#askgmbntech Hello Doddy, My names Yusuf and I'm a beginner and absolutely know nothing about mountain bike trails or anything from the looks of your video. I wanted to buy my first full suspension mountain bike and I wanted to know what would be a good start off bike to ride a few trails but also on the road. If you could also suggest where I can get it from that would be very helpful. Thanks

[@markpapke517]

#askgmbntech Could you please do a Video on how to change the cartridge on RockShox forks (I‘d like to have the cartridge of a Lyrik in my yari forks)

[@bugboy152000]

GMBN Tech #askgmbntech Hello Doddy, just picked up some new Santa Cruz Carbon wheels. Put on my lightly used DHF tan walls. I have not put sealant in yet as it’s winter and will not be able to ride for several months. I’m assuming the sealant will dry up in warm storage thus no sealant yet. Rear tire continues to gradually go flat. Is this a problem?

[@jawide626]

#askgmbntech what's your take on Aaron Gwin's move to Intense? I didn't expect it but the bike looks sweet.

#askgmbntech hi Doddy love the vids but my crank arm is wobbling and is making a weird creaking sound and it doesn’t seem to be loose because I almost broke an Allen key trying to tighten it please help I am starting to get irritated about it and the nearest bike shop is an 1 hr and a half away

For the longest time ive been having second thoughts as to whether i buy carbon or alloy, 27.5 or 29, trail or enduro. This video gave me the best insight. Thanks so much! Alloy, 29er, trail bike, im coming for you!

Who did this

[@Driftuner]

I personally would ALWAYS go with alu and better spec over carbon with cheaper stuff

[@jonaskinner5273]

Pe Peroni but what about carbon with high-end components?

[@Driftuner]

@@jonaskinner5273 i will be honest, ive never owner carbon bikes. I guess if i had the choise, i would still always go with alloy. Carbon is a nice material when done right, and as an engineer myself i know how easy and relatively cheap carbon can be made aa well as how difficult and expensive a "real" carbon frame can be, that being said i dont trust 90% of all carbon stuff out there. Why do you think brands like Santa Cruz, Yeti, Canyon offer the same frame in different carbon variants for different prices? Yeah, one of them is the "bullshit carbon" that isnt half as stiff as alloy and barely any lighter...but still more expensive...i dont trust that stuff..if i ever buy a carbon bike it will be a carbon done right...which hardly ever comes for less than 9 or 10 grand..

[@chucknorris2938]

You have no idea about bikes

[@garrettorpin6584]

@@jonaskinner5273 Check out Viathon - high end components with a quality carbon frame. Hardtail only for mtb right now, but SRAM GX Eagle is the baseline for their products.

[@ForkInTheButt]

Yep and I also don't trust carbon for blunt hits like rocks on frame. I'll take a good spec'ed alu vs carbon

[@devisoutdoors5467]

There are many mtb accidents due to broken carbon frame during extreme bike riding. Some mountain bike riders said that carbon frame from Ch1n@ are easily broken due to the low quality of the frame. And some say that there are many types or grades of carbon frame in the market. If you buy the cheap one means the lower the quality and durability of the frame. Can you explain about the grades of a mountain bike frame and the durability according to each grade?

[@DavidSmith-og1oz]

Excellent!! I'm debating between carbon and aluminum hardtail. This was a GREAT breakdown of the pros and cons. For me, since I'm on a budget, I think I'll go aluminum

[@chrisorr3919]

Re Alloy v Carbon. I bought a Scott Genius 940 recently. Im not racing, so went alloy and I dont want to have to take special care of carbon fibre frames. I think the weight saving on a carbon is a little over 1kg. Not worth it to me, plus I was stretching my budget as it was.

[@cooperallen282]

The main reason bike's use carbon is for ride quality. Carbon gives an amazing ride that is better than alloy. It does save some weight but that isn't the main reason for having a carbon frame.

[@deckmageccg3561]

I buy alloy frames and over time, I work with my mechanic to buy lighter and better components to compensate for the weight. On a mountain bike, especially a Hardtail, I would want the extra durability on the frame.

[@rickmoz]

The new transition patrol GX is a good example. Aluminium bike come with amazing spec with stans wheels fox grip 2 fork and fox 2 shock. 1k more for the basic carbon with less spec....carbon can be over rated in my opinion and aluminium seen as just inferior by the bros

[@timotheus34]

Also the trek slash 8 and slash 9.7... While costing over 1000$ more, the slash 9.7 is still inferiorly specced

[@adanielweaver]

Have you ridden it? I'm looking at that bike since I test rode a stumpjumper evo and liked it, and the patrol has similar geometry.

[@rickmoz]

MTB_SF no I’ve not rode the bike yet....just one I’ve got my eye on for then next demo day.

[@ryangilmore2437]

Depending on what you’re doing aluminum might be nice with the more weight and planted feel on downhill but may not be easier to hop stuff vs carbon which is easier to hop stuff with but feels a bit lighter and floating over the ground vs digging in

[@singletracksender6532]

6:22 triggered the roter is rotating counter clockwise to there intended direction

[@Mapl3Syrup]

I had the actual choice of alloy or carbon transition smuggler and I chose alloy. I don’t worry too much about weight but I also plan on advancing my skills which likely means I’ll crash. I’m more comfortable in the relatability in aluminum bike frames.

[@paulg.4139]

I think this is a misconception. In a reel big crash bothe bikes will get destroyed. Whats true is that the characteristics of a Aluminum frame in a crash is much "nicer". It will most likely bend. But its still unusable. Even when you got a dent in your frame its better to play safe and get a new one. But whatever.... its nice that you found a bike you love. Cheers

[@durtyt4770]

They normally do travel differences for frame clearance. A 29inch wheel being larger in diameter will sit closer to the frame than a 27.5. With the exception of some forks like the Zebb which has a higher mounting point on the 27.5 wheel fork than it's 29inch brother.

[@galenkehler]

Buying a cheaper fork without adjuster dials can be a great value if you're willing to tinker. My JrT fork had really basic adjustment back in the day but I made a great fork out of it by using lighter oil weight than spec.

[@zeusdreadbeard8990]

Imo Always go for Alu unless your racing xc where weight matters. I saw a carbon intense carbine snap in half in a very minor crash

[@henry2902]

Agreed. I've been on an Alu for ages and i have no problems keeping up with / passing high-end carbon bikes in XC!

[@newttella1043]

There are lots of lower grade carbons too. They are more affordable but barely lighter than aluminum. Aluminum is still the better bargain.

[@TFritz82]

I also find that depending on manufacturer, the difference in weight between their 'low end' carbon offering and high end aluminum build is very little - not enough to get bent out of shape over nearly a grand! The price difference stretches much further with the higher end carbon layup builds! IE Yeti standard carbon vs Turq and Santa Cruz C vs CC.

[@azreenklose7976]

I like Doddy's comment on cheap transmission ........Now , I can get an Alloy Hardtail with Shimano cheapest groupset without any hesitation ......as my first bike.....

[@fullcarbon991]

Hi Doddy I just wanted to extend the question about carbon vs alloy, if you had two bikes the same spec but one carbon and one alloy would you save some money and get the alloy bike or spend the extra money and get carbon bike? Thank.

[@zxtenn]

Carbon is nice until you smash into a rock and destroy your $2500.00/$1250.00 crash replacement frame when AL you might get a dent. I have a 2018 Spectral 6.0 and I don't worry about a few pounds between carbon and AL not to mention carbon is usually MUCH more expensive. I will upgrade the M-1900 wheels to XM 1501 and save 200 grams that's it

[@2001MBKBooster]

I love the feel of my aluminium hardtail but for my next bike I'm looking at a different frame material - titanium. But if I had to pick today between aluminium and carbon fibre for my next mountain bike, I would stick with aluminium. Better bang for the buck in most cases.

[@newttella1043]

Only problem with bikes is that they get obsolete. I regret buying a Moots titanium bike 12 years ago. It was crazy expensive now it's so outdated with unfashionable xc geometry, non tapered head tube, 26" wheels, quick release axles etc etc. Even my kids don't want it. Aluminum bike with high end parts is easier to sell after 2 or 3 years when you want something newer.

[@shaunbeakley348]

Also if you are looking at an alloy Stumpy vs Carbon stumpy the same price won't come with the same rear travel, and you can't upgrade that.

[@pedroalvaredo6835]

I had that same question when buying my bike, alloy frame with super good components, or a carbon frame with cheaper components, I chose the allow as it had carbon wheels and fox elite fox and shock with xt drivetrain. I totally recommend this option

[@scottrobbins2093]

Pedro Alvaredo so what did your bike end up costing you? I'm in the same dilemma. just don't have five grand minimum for full carbon bike

[@fra93ilgrande]

[@5492sparky]

Great questions, great answers.

[@Mauricio1141]

@02:04 Had the same problem with my SC SOLO last year. I tackled the challenge of building it myself. The problem was that I installed one spacer on each side of the BB, so when I torqued the cranks to spec, they rubbed against the bearings. Removed the spacers and the crank hasn't come loose ever since. hope this helps.

[@paologiovanardi5342]

I once took my 130 mil travel on a double black in Northstar. Very capable👍

[@justinwbohner]

With the way you guys love coasting down hill like you're on an amusement park ride, your frame could be lead and you'd never notice.

[@KDog2264]

I have seen in person and on videos carbon bikes taking fairly light hits and that cracks the frame, I think carbon frames are very over rated, and no we’re near as strong when you crash.

[@kovkou1]

This episode helped A LOT! Thanks and keep it up 🙌

[@didaccarbasa7676]

Hey! I think the user who asked about floating brakes didn't mean floating discs. I think he was talking about those floating brake mounts to avoid interferences with rear suspension

[@tom6493]

Wrong....the "rivets" on Hope rotors are in fact made from Spring Steel and allows the friction surface to move independently from the alloy spider (same construction as a motorcycle rotor), meaning they are in fact floating, unlike the solidly riveted SRAM and Shimano rotors. Secondly, floating rotors only rattle if the retaining springs have lost their elasticity due to being subjected to excessive heat (continued dragging of the brakes can do this due to heat soak). If this occurs, bin the rotor as its structural integrity is compromised and could lead to a catastrophic failure.

[@daleheffernan]

Ryan in some cases the alloy bike might look better than the carbon version as well (at least that is the case with Transition bikes in my opinion).... on that note Transition bikes generally has a pretty good bang for your buck, can sometimes even rival that of the direct brands.

[@Malio75]

The aluminum vs. carbon debate is still interesting. I have an aluminum version of a model that has a carbon twin for the same amount that was stated in the vid. Same price. Both bikes the same weight. The cheaper components add the extra couple of pounds and even the manufacturer admits to expecting riders to upgrade down the line on the carbon.

[@ruanvorster2596]

I ride loads of reds and even black on an XC hardtail

[@Snitchy1989]

i run red routes on a hardtail, with 120mm front travel... All good

[@lusenator]

I don't know if you SHOULD be bottoming out your travel, that seems off right? I've never heard that advice

[@src248]

Not often, but very occasionally means your suspension is set correctly

[@bluestraycat]

Agreed, you should only expect to use full travel on big features like drops and jumps. If you don't ride these sorts of features, you could expect to use most of your travel over very rocky & rooty sections, but not to the point of bottoming out.

[@RCWildvideos]

I use up my 140mm rear travel on just about every ride. That is with a 25% sag setup. Set the sag right and if your bottoming out too much you can always add some volume spacers to progress the shock through its travel.

[@rollinrat4850]

Neither one. Steel is real!!Steel (or titanium) will last longer and endure more abuse than other materials. Steel bends and dents, it doesnt fail catastrophically. Order a custom frame. You get EXACTLY the bike YOU want. Not what marketing idiots think you want. You know who built your bike and maybe support your local economy. If you have issues, you know who built your bike and whose feet to hold to the fire! Ive never had issues with my 5 customs over 40 years. Every one of mine are still ridden. The price can be competitive with upper mid level to high end carbon. There are quite a few smaller name builders, usually one man businesses that are more affordable than the big names and you probably wont wait as long either. I ride and recommend Rock Lobster of Santa Cruz. Paul is a great guy, great work ethic, great quality and over 30 years of experience!!!

[@Jeerven]

I really want a Carbon XC bike but my mom FORCES me to get a alloy just cause the guy at the local bike shop said "Carbon brakes easily" 😩😫

[@BMH1965]

This has dated fast: the cost of production for carbon and alloy frames is nearly the same today. Any significant price difference is due to profiteering by the importer or shop.

[@Bungle2010]

The same? Carbon fibre is more labour intensive to produce, and therefore more costly.

Hey Doddy, some feedback...please can u cover more questions, by having way shorter answers...almost 1/3 of this show was on one question which u answered in the first min of the 4 min answer...just means others miss out on getting their q's in. Your clearly a detail guy like me, but often the answer gets burnt in the toaster imo....maybe a yes/no/dont know Segment also... like the ask gmbn quick fire round

I always thought the shorter travel 29 was due to the room when the larger back wheel moves up. And to have more travel they would need longer stays. But that was just a guess

[@elvis929]

#askgmbntech Hi doddy. I have two questions. First one - How do you build and trials bike simmiliar to Danny Mac's orange bike? Do you buy dirt jump frame and seperate fork or are there any trials type of bikes, that came with frame and fork together? Asking because i do not want an reak trials bike, i do not like the look of those. And second - How do you tell the differences in tool hardness and stifness? Like with steel tools - How do you tell which is hardened, which is more durable and so on by colour or what? Asking because there are good bargains on good tools, but a lot of them say that they're made from metal...like what sort of metal? Thank you!

[@ShermanStrike]

#askgmbntech Last Christmas I was given the promise of a new bike of my choosing. I live in the northern parts of Sweden and temperatures regularly drop beneath -20°C, and I love to be able to ride in the snow. I'm currently borrowing a 2015 Fuji Wendigo (on 26x4.7 Vee Bulldozers) fatbike for the first time and I must say that I'm loving it even though it's a 17.5 frame and I need a 21.5er. Either way, no matter where I look I always seem to come back to the 2019 Trek Farley 5, a 27.5x4.5 fatbike. The thing is, I doubt I want to run a fully rigid fatbike in the summer. I've seen a lot of people talk about changing to 29+ wheels, both with and without adding a suspension fork, during the summer. Not only do they fit, but it won't "compromise the geometry". Now, finally to my question. Do you think that changing to 29+ tires on a fatbike is a good idea, and what does the aforementioned quote mean? Also, from what I've read, it's not worth bothering with a suspension fork when it gets this cold, would you agree with that? A little sidenote, I currently own a Merida Maroon Matts. I mostly do urban mountainbiking and commuting, but I'm getting into trail riding more and more. I should note that rolling resistance is not my biggest concern. The way I see it, it's just more calories being burnt and I really need to loose a few extra kilos, gone from 99 to 86kg last year, I still have ways to go. Also, excuse the mile long question. It's my first time doing this.

#askgmbntech hey there! I have an X fusion Hilo dropper post that I have owned for 6 months and it is starting to sink slowly through the the top of its travel when I sit on it and slowly coming up when I am not sat on it. The air pressure is right so I don't know what to do. Any help?

[@dancingkids5158]

I'm no Doddy but i have the same problem. Have to add pressure every two weeks now. Oil has started showing on the stanchion. From what I've read the hilo doesn't have the greatest reliability. I'm thinking of changing the seal kit again (done that once a year ago), but I'm looking at replacing the whole unit if the problem crops up again. Not worth keeping in my opinion.

[@StevefromCincinnati]

I have 2 bikes with hilo droppers, they both did this to me after install... check the cable first and make sure it's not too tight. It has a barrel adjuster on the lever. Try to loosen it a bit. Been using one for more than a year and the other for 6 months. No problems since.

#askgmbntech My SRAM NX derailleur since day 1 of having my bike doesn’t go tight. The bolt tightens up but the derailleur still has a large amount a side to side movement. I’ve checked and everything is tight but the derailleur still moves.

[@TFritz82]

You mean a mounting bolt?

[@benkemp6546]

I had the same problem with my GX derailleur. On the main pivot bolt where the derailleur bolts onto the frame, there is a spring behind the b-tension collar which needs to be held back with a circlip that sits in a groove on the bolt. On mine, the circlip had popped out meaning that the bolt bottomed out before it was tight. It can be a bit fiddly to get the circlip back in, but if you use a flat bladed screwdriver and a bit of patience you should get it!

Sure, you love carbon-fibre MTB frames, but it ends up as carbon-fibree because as my old bicycle courier pal #46 Simon Osborne found out on his carbon Specialized you crack a frame that has to be, as MTB's go, so heavy-duty it's outweighed an aluminium MTB frame the Consumer Laws in most places say "replace with comparable or better quality item" so YOU get aluminium under warranty Simon was given an Avanti, then there's my exwife Samantha also a courier for a few years on the bicycle she had a basic accident destroying her then brand-new Mongoose SX120 Pro and given a DBR as replacement, yeah fibree

#askgmbntech Hi Doddy! I currently own a 29er hardtail and it used to be 3x but I converted it into 1x 30t (I have 11-36 cassette), but made me a bit slow on the bike lately, even at high cadences. Our trails are around 7-10 km far and I used to sprint as a warm-up, so I wanted a bigger chainring for that purpose, but I don't want to use a front derailleur anymore. I've heard of Vyro Cranksets (24-36) and it had a nice review, but I don't hear many people talking about it. What are your thoughts about it?

Ask gmbn, I have nukeproof horzony pedal and have the bearings and bushings to service them but I can not find the bushing tool, online, is there another method to remove them, I have noticed chromag use a Tao to remove the bush in theirs, would this be a ok option with the horizon I don't want to damage the pedal body and nukeproof won't answer my enquirys and it's honestly put me off a company I was a massive fan

[@Mo-po8xc]

#askgmbntech Somebody told me once that I should shift to the smallest pinion when I don't use my bike for a longer period of time to relieve the pressure off the derailleur's springs. Do the springs really wear out by staying in a bigger pinion? Thanks for your Q&A - it's great!

#askgmbntech Hi Doddy love the show watch it everyday and has taught me lots about bike history. I have a question relating to broken spokes. I have a 26" rear wheel ( transition revolution 25), which is a Norco fluid lt2, a bike that spends most of its time riding park and jumping. In the last 3 months, I've had 5 or 6 broken spokes ( all at the j bend). I was wondering if there was anything you recommend doing to prevent spokes breaking, finally, it would be awesome and useful if you could do a video on how to replace spokes. Thx Arif Khan

#askgmbntech I am a mtb starter and it has been 3 months since i bought a cube aim pro xc starter level hardtail , i also shoved a rockshox recon rl 100 mm last month . Should i keep upgrading it with better wheels , bars and drivetrain , or should i buy another bike ? I ride lots of roots and rock gardens btw. Thanks in advance

#Askgmbntech does is it really matter which way you put the rear shock? I’m think of upgrading mine thanks!
