I just bought Roam V2. UI is really great and as everyone else here says, "Very easy to set up". Best pricing, simple setup, and easy to use; it's no brainer.

[@mlegrand]

Great feedback Eric! Thanks for posting this!

[@TiagoFerreira-w8c]

I had the first bolt and now the new roam, I set up bolt years ago and never needed to change anything. Synced the backup to the new roam v2 and it's done... Amazing! And the ability to just save the track on dropbox and open it on the phone and it's done... amazing!

[@GravelHerault]

I have a Wahoo Roam v1 and just bought a Garmin 1040 solar because the Roam was lagging a bit too much for my liking. From my early testing, the Garmin lags the same, is less readable even at max screen brightness, the UI is more cluttered and hellish to configure, the maps are cumbersone to read in any mode and details level… I've been suggested to navigate using turn to turn direction instead, there's no alternative world where I can do that. I'm gonna send the Garmin back and upgrade to a Roam v2, hoping for a little less lag with map refresh. Wahoo has definitely got it right with their easy to use products.

[@mlegrand]

This is awesome feedback even if it’s not positive. I’ve also been gravitating towards the Roam v2 lately. It’s just easy to use. Thank you for watching and taking the extra time to comment. I really appreciate it. 👍

[@jamesturner9858]

I have used the Garmin 820, 830 and now the 840. I go with the 8 series Garmin because they have full navigation unlike the 5 series that is more of a cycling tracker. That tracks where you have ridden. The 8 series is great if you like to ride new roads in areas that you are not familiar with. You can create a course right from the device or you can enter a specific address or point of interest and the Garmin will direct you there using cycling routes. When I travel and rent a bike I must bring my Garmin to create myself a cycling route of what every mileage I would like and bring me back to start. The 5 series you use to have to download a route to follow, I’m not sure if that’s has changed with the new 540

[@mlegrand]

Great feedback James! I think you'll like the 840. The new UI feels like it was really designed around that touchscreen. Thank you for watching and taking the extra time to comment. I really appreciate it. 👍

[@jimpeyton1459]

I have the Bolt v1, still going strong. Been looking at the Roam v2 and Edge 840. Wahoo is so super easy to setup, but comparing these two is running me in circles. Some days I'm sold on Wahoo's simple approach, other days I'm swayed by Garmin's ecosystem. Thanks for the rankings by attributes...

[@mlegrand]

The Bolt V1 is a fantastic option. I think I'd still be using mine if I wasn't reviewing bike computers here. Thanks Jim!

[@AJXOXO-vz1pn]

I had a Garmin. It was great until it start getting buggy. I would recommend to go with Wahoo. Garmin needs to get better tech guys or whoever does their software updates because they are sooooo bad at it.

I also have the Bolt V1. The original one I got had battery charging issues so Wahoo replaced it with a “refurbished unit”. Now that I want to replace it, deciding between the 840, 1040 or Roam v2. 🤔

Great video. The section where you ranked them on different features was fun. Fast and to the point yet informative.

[@mlegrand]

Thanks! Yeah, I’ve never done that here before. It was kind of fun 👍

[@ltu42]

I bought a Garmin Edge 840 and after 2 months decided to go back to Wahoo Elemnt Bolt v2. I think the data presentation is better, there are fewer screens to switch to see the data that interests me. The map is much more readable on the Wahoo, and the elevation chart is much more informative with the altitudes labeled. But the killer screen is a map with 4 fields and an elevation chart. I experimented with the Garmin setup and Connect IQ fields that solve some of the issues, but I just like Wahoo better. As for battery life, I think Bolt and 840 are on par: the Wahoo promises 15 hours and delivers 17 hours in practice, whereas Garmin promises 22 hours and delivers also around 17.

[@mlegrand]

Amazing feedback for people to consider. Thank you for watching and taking the extra time to comment. I really appreciate it. 👍

I used to think Wahoo were so fresh and user friendly then went back to Garmin for all the features. Hammerhead 2’s battery not great because of high res screen. The hammerhead 3 should be very nice. I’m staying in the Garmin eco system with my Epix pro watch. 840 is really the sweet spot as Rainmaker says. Subscribed!!!

I own an Edge 840 and a K2 and definitely prefer the K2. It was easy to set up and is easy to use. It’s very intuitive. It’s also very easy to import a route. Like, way easier than on the Garmin. I also like that HH is updating the unit every two weeks, so we’re always getting new features and improvements. I also appreciate the larger screen on the K2. I’ve never used the Wahoo so can’t comment on it.

I went with Roam Element V2. Today was my first ride with it and love it. I am new to cycling so knowing what gear I am in is helpful. I was told Roam Element V2 was the only computer that will tell you what gear you are in so that was why I went with it. Also the climbing feature does what I need which is tell me % gradient and distance to the summit. All so cool.

[@markflorence11]

Thanks for the great review. Interesting what features people find important. To my knowledge, only the Garmin offers incident reporting (notify a pre-determined person in the event of a crash). Also Garmin Connect is quite useful for route and workout creation without need for an additional subscription. I've not tried the Karoo but the Garmin does the best job of live tracking too, the Wahoo lags a lot, at least in my area. It's too bad because I like the display and the UI of the Roam 2 much better. The Roam 2 syncs seamlessly at the end of a ride, while the Garmin often has to be forced to sync. This has been a frustration since the 30 series, in my experience anyway.

[@mlegrand]

Great feedback Mark! Thanks for posting.

[@Xhadp]

Went with the roam v2 because of its compatibility with a radar utilizing the lights with the radar function and didn't really look into other bike computer options. I'd say that I am happy with it so far. Just not finding myself using the vertical light bar and just using the top one for radar so maybe the Bolt V2 might've been better. Oh well maybe the increased screen and battery size of the Roam v2 was worth it. At the end of day most of the features seem pretty similar among the bike computers so I think it is more of a matter of preference about which company, price point and nitpicks determines which one you go with.

[@mlegrand]

I really like the Roam v2. I think it's very visible in direct sunlight. I don't think you'll be disappointed but keep me posted on what you think as you go. Thank you for watching and taking the extra time to comment. I really appreciate it. 👍

When I started cycling 4 years ago was thinking of either buying a Wahoo or Garmin device, my dad got me the Wahoo Elemnt Roam V1 back then. Unfortunately it somehow got a waterdamage recently, but the costumer service is awesome. I contacted them and after 2 weeks I got a new Elemnt Roam and it is the new version as well. I don‘t know how the costumer service is with the other brands though, but Wahoo is 👌

[@mlegrand]

That's awesome to hear. Customer service is something that my reviews really lack. I think it'd be interesting to make an entire video on just that subject.

[@AllenStauffer]

I’m all over the place on this one… I bought a Bolt v2 as my first cycling computer - but I do probably 65/35 MTB to road riding, and *none* of the MTB trails near me were on the Bolt (and we have a lot around here!), so I returned it and grabbed a Karoo 2. I actually liked it, and (almost) all the local trails were there, but I exchanged it for a a Garmin 840 because I use a Garmin watch for all of my running and wanted my cycling in Garmin Connect. I’m actually kind of hating it, though - it just beeps at me nonstop, for jumps, for strava segments, for being off of a strava segment NONSTOP because I’m riding an adjacent trail, for riding without my radar, even though I’ve disabled it in the sensor menu, because I’m on the trails that day. The only option was turning off ALL alerts, but then I miss the beeps for navigation and radar when I’m back on the road. 🤯 Starting to think keeping all of my tracking in the same eco system just isn’t worth it and I should save the $200 and swap back to the Karoo 2. Do you give any consideration to where things end up tracked/stored when you choose? I saw the end of the video (“get the best computer for you, don’t worry about mix and match”), but on paper the 840 does seem to be “better” - I prefer the size, I bike a lot in dense woods so the multi band gps is better, some other minor things. I’m just so tired of it beeping at me 😅 Or do you have any advice for unbeepifying the 840? I’ve turned off the jump alerts, but the radar disconnected alerts/beeps seems to be a bug (reported on the forums at least) and only thing I’ve found for fixing the strava segments is to turn it off completely, Hah.

[@AllenStauffer]

Just took it for another ride and I at least didn't have the radar thing beeping at me, but the last 30 minutes of the ride were "Off segment" beeping and popups that just returned after dismissing them, and then an undismissable "26668 mile" climb popup???? 🤦‍♂️ I love my Epix, but this thing is just a pain.

[@mlegrand]

I will say that I've encourage many people to mix between brands. Everything might not be on Garmin Connect but you can sync everything to Strava or Training Peaks to have a central repo of all of your activities. I don't have any unbeepify tricks. Sounds like it's trying to navigate some detailed trails that are close by other trails. 😬

[@AllenStauffer]

​@@mlegrand Yeah, something like that - even with navigation off and not following a Course! 🤯 I messed with it a bunch this morning before work - I just cannot figure it out, about to give up. I'm starting to think I might have a buggy unit, 26,000 miles is more than one trip around the planet. Where would I be climbing to??😅 Oh well. 🤷‍♂ I do sync everything to Strava, but it doesn't give the same recovery metrics, training status, VO2 estimates, and such that Connect does. I frequently ignore the recovery metrics, so maybe that's a sign that I don't need them as badly as I think I do. I've never used Training Peaks - I'll have to check it out and see what it offers - the "feel free to mix and match" advice is really freeing and encouraging, maybe I can use TP to break free from Connect and brand lock-in. 🙃 Thanks, Matt!

Nice comparison, I have the 1040 and tried a HH K2 at the beginning of the year - never tried a Roam. Probably the climbing feature would have been another comparison - each now have as you ride climb data features, and Wahoo's is pretty good here.. This has been a big one. Hey, I think the Endurance specialist is just someone who does most of their riding load in Zones 1-4. Add lots of hills and you become a climber, and then doing less mileage and do crit racing will turn you into a 'well whatever the last one is.' It's a meaningless measure and needs to be removed IMHO.

[@mlegrand]

Yeah, it's not my favorite feature by any means. I'd be curious to talk to someone who is finding it helpful. 🤷‍♂️

[@NeilLavitt]

@@mlegrand it’s a great feature for long climbs > 175m vertical ascent that require Zone 3-5 efforts. Pacing on those climbs is always important and the climb features give that information up front. Probably for the Gran Fondo riders. All 3 do this now interactively.

I just returned from a vacation in Nice where I did a couple of rides with my wahoo bolt v2. I was really frustrated by the routing of wahoo when I needed to change my route. I was on a road bike but it insisted on defining a route on a trail when I needed to route home early after overheating. Extremely frustrating. In the end I had to create a new route using ride with GPS to get me back. I could not find any wahoo settings to stick to road routes. I doubt this is a situation that everyone will run into, but when you do you need it to work. I’m looking to leave wahoo for bike computers as a result.

[@mlegrand]

It's not that unusual of a scenario. I've fount Garmin's onboard routing to be a bit better than Wahoo's. I also think it's great for people to hear that kind of experience. Thanks so much for taking the time to comment here. 👌

[@alexmseu]

Great comparison, thank you! Quick question, for the money (I believe it’s a $25 difference), which computer would you pick as your daily go to: Garmin 840 or Karoo3?

[@mlegrand]

Tricky call. The 840 has a bit longer battery life so maybe that one. 🤷‍♂️ They're both great. What kind of stuff will you be using it for? If you mountain bike, I'd say the Garmin has a few more featured geared specifically towards that type of riding. Otherwise, it's kind of a tough decision.

I travel (camp) about once a month where the terrain can be unpredictable (fire roads, gravel, MTB trails).

Hi Matt! I have a trek 920 that I use for commuting to work (40 miles round trip) per day, riding the best of our nations rails to trails and doing more self contained bicycle touring. I use a basic Bontrager battery computer, and my phone for navigation...when it's not overheating. I am wanting to upgrade and purchase a computer with all the basic computer features and good navigation/gps features. I recently purchased the 840. After unboxing it, I became a bit overwhelmed by all its coaching features (most of which I would not use). Also, does one need sensors--cadence and/or odometer? Don't really care about my cadence and would not use the HR sensor as my watch reads HR. I appreciate your feedback.

[@mlegrand]

The 840 is a fantastic device. But it is a bit overloaded with features. If you're within the return window, it might be worth considering switching to something like the Wahoo Roam (also featured in this video) The wonderful thing about the 840 is the mapping and routing. Don't feel obligated to get heart rate monitors, speed cadence or a power meter if those things are of no interest to you. Best of luck Deborah!!!

Thanks for the great review! I’m going in circles thinking about this as my Bolt v1 is dying, with the additional thought that a Karoo 3 may be on the horizon. Also, it looked like you had a mount for the Karoo for the BMC ICS cockpit - was that a 3D printed one, or was it a Garmin mount with the adapter? And did I see that a power cable was connected to the Karoo while mounted on the bike, early in your video?

[@mlegrand]

The Karoo was using the Garmin mount and that little cord was just a 3d printed usb-c cover with an attachment so it doesn't get lost. I think I talked about it in my full HHK2 review. If I were you I'd at least wait until the HHK2 goes on discount (next week maybe?) but my main concern is that it'd be going on sale because of an upcoming update. But I honestly have no idea.

Hi Matt. Did they improve the total height and current incline calculation in the 840 model during prolonged rain? In the 830 altimeter, it miscalculates height and incline when water gets into the sensor.

Hey Semper762, I actually don't know. I've used it in the rain but didn't notice an issue. I've even used it while it was hailing but that would actually be easier on the altimeter because there's less chance for rain to block the sensor.

[@kpolszewski]

Which one do you think gives the best turn-by-turn prompts and well handles making a detour of a previously downloaded route? I have a Garmin Edge 530 and it tends to force me to do a U-turn even a few kilometers in when I'm 50m away from merging with the original route.

[@mlegrand]

Hard to say. It could even depend on which route you're doing within these devices. Hammer Head says that there device is the fastest to re-route but I still think Garmin does the best job. Thank you for watching and taking the extra time to comment. I really appreciate it. 👍

[@wolf-gd3oc]

Between the garmin and the hammerhead which one would work better for MTB as i am racing mtb now

[@mlegrand]

I would say the Garmin. Better trail details , mapping and routing. It also has a few MTB specific metrics.

[@RonaldPoulin]

Do you know if we can control screen with the button of my handlebar grip,I have di2.

[@mlegrand]

Yes that is an option on the Wahoo computers but not the Hammer Head Karoo 2 due to Shimano having issues with HH’s new parent company.

[@randibechtel879]

How easy is it to upload a route to the wall who? I’m not super text savvy so basically, I plan a route on my Google Maps app and I’ve been using my phone. But when I’m doing more than a century ride, I kind of would like some thing else versus just using my cadence monitor…. I’m looking at the Garmin 840 bundle and also the bolt by wahoo. But which is easier to upload a map and track my avg mph and cadence

[@mlegrand]

The Garmin has more flexibility in how you upload routes and the Wahoo requires the smartphone app.

[@radekgacek8050]

I can get on promotion for 260euro hammmerheaf karoo 2 with hr monitor or Wahoo bolt v2 bundle. What do you advise to buy ?

[@mlegrand]

It depends on if you’re ok with the slightly lower battery life and the bigger screen of the K2. It’s a very nice device and it’s always great to save money. 👌

[@RonaldPoulin]

Do you know if we can control screen with the button of my handlebar grip,I have di2. with the Roam v2.

[@mlegrand]

[@Ahl3rt]

The Karoo 2 now only costs 260 EUR instead of 400. If you had to pick would you take the Karoo 2 over the Roam V2 as you get to save an extra 100 EUR?

[@mlegrand]

That’s a lot of money. I’d probably save the cash. 💰 But I also don’t need the massive battery life. However I’d be very curious to see if HH would be developing a Karoo 3. 🤷🏻‍♂️

[@alexperit]

Is it possible to connect Wahoo heart rate monitor/sensor to Garmin EDGE 840?

[@mlegrand]

Yes, Wahoo's HRM is designed to work with third party computers and devices. The two should work well together. I typically recommend people mix and match between the brands. 👌

[@andybrown141]

I think it comes down to whichever device is the most visible at the end of the day . Features are irrelevant if you can’t see them .

Well, at least you got a deal on the 1040. That’s a great device. 👌 My fear would be that a Karoo 3 might pop up soon. But I honestly haven’t heard any rumors yet. 🤷🏻‍♂️

[@ЛёхаБукреев]

It look like Karoo 2 has not enough brightness on a sunny days. Are there any problem with it in reality?

[@mlegrand]

Battery life in comparison to the other options is a problem and I would agree that the screen is great but not as ideal in bright sunlight conditions.

[@kithinders1086]

There are some HITTERS! The computer name text is very pretty. LOVE USB C. I'm curious about the climb type feature...I'm not sure I want to know! Ahhhh, battery life. We're here! I had a Karoo for a couple weeks before deciding it wasn't for me. I noticed the battery life was rough on the Karoo. You joke about "not riding for six hours"... did a 10 hour ride due to a snow storm halftime. It was horrendous. The battery saver, that's where the screen turns off, right? I love that mode! I don't want my computer telling me how disappointing I am. Is there something different about your color grading? Your shirt seems blacker than it normally does? That stamina/stamina potential seem really interesting... have you used them extensively, or are they more of a gimmick? I loved the bit at the end where you physically moved the best computer for the given category. Nice work!

[@mlegrand]

Thanks Kit! Battery saver can dim the screen or change GPS modes or a few other options which are configurable on this 840 (also 540) I'm always color grading these videos slightly differently so yes, my shirts might look different. I don't think Stamina is a gimmick as much as 'Cycling Ability' but I also don't use it that much. Typically, it doesn't effect how I would ride but maybe it would if I was doing some sort of ultra endurance event? 🤷‍♂️

[@kithinders1086]

@@mlegrand I must do more research on this stamina feature. It is quite interesting. For example, big ride... first half of the ride, I felt like do-do. Second half of the ride, my buddy felt like do-do but I felt great. Wonder how the stamina feature would have graded us.

[@FrankFiorentino]

I used the K2 for several years and the battery life was terrible. I use standard sensors…HR, power, shifting and radar. I also use live tracking since I often bike alone. The K2 battery would get uncomfortably close to drained on a 100km ride. There is a also n ongoing problem with K2 elevation being way off. I wound up switching to the Garmin 1040 and I am much happier.

[@mlegrand]

Thanks so much for posting this really valuable feedback Frank. I think this will help a lot of people trying to figure this stuff out. 👌

[@rocstar76]

I've been using the K2 for about a year and a 100km ride with all the sensors uses about 30% - 40% of my battery. Not sure what was going on with yours but I don't think it was normal

[@FrankFiorentino]

@@rocstar76 I wish it wasn’t normal but I am not alone with this experience. HH replaced my unit and I saw no improvement which is why I switched to the 1040. My last 2 rides I logged a total of 200km with all sensors, tracking, multiple data screens and interacting with the unit. I charged before the first ride and I still have 53% charge remaining. The K2 is not in the same league with battery. The K2 is a nice head unit and I am keeping it as a backup but for my needs it’s not good enough. It’s great that we have so many choices and quality head units to pick from.

[@obidr]

My experience has been completely different. In fairness, my first ever ride with the K2 was a 100 Mile race (160KM) and it did die before I ended. It died about 140km in. However, and this is a bit however, since then it has DRASTICALLY improved through its regular updates. Now, I just fineshed another 100 mile race and I finished with close 60+ battery life. That is with power meter, HR and wifi on.

[@FrankFiorentino]

@@obidr I am glad it is working for you. Mine is not working for me and I am on my second unit (after they replaced the first one). Personally I don't want to have to sacrifice the number and the type of data fields in use, limit the interactions with the computer, keeping the brightness at a level that was not readable for me, always using battery save mode and sacrificing other features just so the battery would not die on a 4-5 hour ride. With the Garmin 1040, I don't have to worry about any of this and I can get multiple rides out of a single charge. I understand that there are K" users that are OK with the battery performance but that does not mean it is not there. There are so many reports about battery life to think it is isolated. I stuck with the K2 for 2.5 years before making a change.

[@joenevins]

Just bought the 840 (had the 520) but returned it the next day. While the connectivity is so much better, it still has crap graphics and screen. Not worth the money IMO.

The only good thing about the Garmins these days is battery life. They come full of fluff software that is useless apart from the Climb feature.

[@uptown710]

It really depends. I bought a garmin because I have vector 3 pedals and an epix 2. The amount of data I get back is actually damn astounding. It even shows me how much offset exists in regards to my foot position relative to the pedals. Most avg users may not need this info but that doesn’t make it fluff.

[@johnschwenk7722]

While I love my Karoo 2, I am super disappointed about Shimano Di2 not being allowed on their platform without a hack or sideload. They should buy the sideload company. And Shimano should stop blocking them from uploading Di2 data. May move to Garmin 840

[@mlegrand]

Yeah, that’s on Shimano. That’s a pretty crappy move by them.

[@gijsnooteboom8769]

hey Matt, I am wondering if you really have used the K2 in full. Me being a heavy and enthusiastic user I think its a device on its own. Made for cyclists by cyclists. Its graphics, personalisation power, side loading of apps, it even doesn't look like a Head unit...to me a far more pretty thing to look at it from a screen point of view than the others. And enjoy the integration into the hoods for Di2 users. You didn't mention the amount of pixels, which is twice that of the Garmin/Wahoo.....Just saying.

[@mlegrand]

And have you noticed that it's been on mega discount lately. I'm seeing $250 👀 Could be a great option for people. I hope that they're working on a K3.

[@gijsnooteboom8769]

@@mlegrand Not sure what the K3 would bring other than the K2. The rider that is looking for more battery power could be the one but the ones that are riding more than 6-8 hrs per ride is a small market. Let us see currently you are right it is very good value for your money!

After my second Garmin Edge 520 died unexpectedly I decided to try something different - the Wahoo ELEMNT Bolt instead of the Garmin 530. Boy! I'm glad I did. kzbin.infoUgkxXZCtB-wGdHVTBSz8RswePK5vllHNi06N The display on the Wahoo Bolt is much easier to read. I like the configuration of the display more (up to 7 items visible on page 1 without scrolling and the first item chosen is larger characters than the next 3 rows that have pairs of items (still very readable). I also like the configurable item selections. The Bolt synced with my Garmin ANT+ Speed sensors on both bikes easily so no additional investment was required there. While the rated battery life is a couple hours less than the Garmin 520/530, I easily get a weeks worth of 1+ hour rides before recharging (and it's never really low on charge). At the end of a ride syncing to the Wahoo app, Strava, and Apple Health app is painless.
