2018 Trek Roscoe 8 Rear Boost 141 Hub Upgrade!

[@ToogyHowser]

I updated the links to the rear Hope Pro 4 hub and the conversion kit in the video details, make sure to select the 28H version of the rear hub

[@alexivanchenko7889]

many thanks! 😇

[@sportmedtech]

Would this work with a Roscoe 6 as well? It came with Formula DC-2241, alloy, 6-bolt, Shimano 8/9/10 freehub, Boost141, 5mm QR and it’s total junk and Trek really doesn’t have a fix for it. Thanks in advance!

[@thatmtbguy5211]

Did u have to get new spokes an if so why kind an size I’m about to do this to but I need to know exactly everything I will need before race day

[@TheTrace8]

Can't find that conversion kit. Ebay is going to be a moving target... I just found that for the Pro5, the kit is HUB257. Found some of those on Ebay. $28

[@TheKubaX]

Hey, I have final solution for everyone! If you will buy ANY hub for thru axle with Boost (like 12x148) with possibility to replace end caps for quick release, you will get 141 mm width. End cups will adjust width from 148 mm thru axle to 141 mm QR. I have done it with Mavic CrossMax 29 Boost 12x148 (R2468110) and Mavic QR ID360 end cups 9x135 (V2510801). Final width is 141 mm. And you can do the exact same with DT Swiss, Hope, Bontrager or any hub with replaceable end cups. Mavic is probably the cheapest, you can do it for around 140 EUR. Other mentioned brands are 180 EUR for Bontrager and 220 EUR for DT Swiss and Hope.

[@ToogyHowser]

very true, I did the same with some Bontrager 29" wheels for the Roscoe

[@TheHawer7]

Thanks!!

[@mikemacias6319]

Do you know if that works for a xcaliber 8 2018?

[@mtmiller302]

@@mikemacias6319 - it's the same frame, so it should work jut fine.

[@pietergodderie7923]

Hello Kuba. I've bought a Mavic with Boost 148 and the conversion to quick release, but it does not seems to fit on my 141 quick relase frame from Giant. Probably I do something wrong. Do you have somewhere some instructions for the installation of the adapters?

[@SuperSnipehunter]

Lacing wheels is tedious, but extremely rewarding. There are a ton of videos here on KZbin that will show you how to do it. Hope hubs are extremely sturdy, but out of my price range, where function and cost are concerned. It sounds great though.

[@toooldfortwowheels2048]

This made my day, didn't realise Hope did a conversion kit and those Forumla hubs are far from optimal and I've heard a lot of people slate those specific ones.

[@mtbthrillseeker5487]

OMG Toogy, you just solved the issue I have with my Roscoe 7. The slap in the hub drives me nuts. I will look at the Hope option you chose, it looks like a good one. Thanks my Roscoe Brother.

[@ToogyHowser]

Glad the video helped out!

[@maccueto2613]

@@ToogyHowser hi there. Will this conversion work on microspline freehub?. Will buy the hope pro 4 microspline boost 12x148 and convert the end caps using this hub 238. Would it fit?

[@GamesBond.007]

That hub costs 1/5 of the entire bike man (plus spokes and lacing). You can buy a very good wheel for the price of that fancy hub. I mean I cant justify spending 200 Pounds just to change a HUB, on a bike that costs 1000. Are there other alternatives ?

[@JimmyBeanz13]

@@GamesBond.007 I only did it because I am going FS next year, and just ordered a Big Al frame to upgrade the rest until I am ready to transfer the parts over. Pass my X-caliber 8(same frame) off to my son with the stock parts on. Cartridge bearings are a huge improvement alone, I built a entire new wheelset though

[@KILLER2280]

Hi, what length of spokes did you choose for the 27.5 rear wheel?

[@jmack2010]

Just ordered an Industry 9 Hydra rear hub for my Roscoe 8. Can’t wait to get it laced up! That stock rear hub is ATROCIOUS! Just an FYI for anybody looking to upgrade a Roscoe to save you some headache, I9 offers their hubs in boost 141 qr so you don’t have to mess with converting a 148 hub, and they offer all driver bodies so they’ll work on any drivetrain. They also offer their hubs in 28h so it’ll work with the stock Bontrager Line 40 rims.

[@RideAlongside]

The Trek Stache has the same hub and I am also upgrading the rear hub to the Hope Pro4. Love my Hope Pro2 hubs on my El Monsterachi. They are going on 4 years. Excellent hubs.

[@ToogyHowser]

yes they are! At least with the stache you don't have to worry about swapping out endcaps lol

[@sanjinred]

Thank you so much for this vid. I have a 2020 Roscoe 7 and it has been hard to find a fitting hub. I love the bike but the rear hub, Trek: I CANNOT BELIEVE THAT YOU HAVE CHOSEN SUCH A SHITTY BAD FORMULA HUB QUALITY ON A SUPREME FRAME LIKE THIS. I sent a mail to Trek about this because I am so disapointed. I'm an engineer and worked a lot with materials and metals, the metal they have chosen, not to mention the unbelievable bad dimension quality, it should have been a mass law suit. My hub is completly destroyed and I havent ridden my bike for 2 straight months in the wait for Trek to respond. They didn't so I am getting a Specialized next time. It is such a shame because the Roscoe has such an incredible fun frame! Still, I'm keeping the bike and I am upgrading with the Hope hub my self, thank you :)

[@Big_Boi23]

Ahhhhhh so it's not just my Roscoe with this issue!

[@wadepratt9654]

Exactly what i needed to see. I remember watching this video awhile back but now watching it again i see you have the exact hub size i do. Thank you again toogy🤘

[@roddieko7330]

I realize this video is a few years old, but if by any chance, you're still getting your service done by the same LBS... beware? As many have already pointed out, the cassette was indeed loose. If the shop installed it, that's "very bad". Additionally, they goofed the wheel build. Valve hole is incorrectly clocked with the spoke groupings. This is not as bad as a loose cassette, but that shop charged you for a service that was executed subpar. Being that you are seemingly quite knowledgeable and care about your bike, I just wanted to mention this. In any case, this is a very informative video--thanks!

[@ToogyHowser]

Thanks and yeah I had issues with this wheel build and issues with that shop! Check out this follow up video kzbin.info/www/bejne/hKKQeJuAoN5rbq8

[@andrewscasualmtb]

That's a loud hub. I like the quieter ones and if I'm rebuilding a wheel with a new hub that's exactly what I would get. That did look great and the engagement was much improved.

[@hermittranslator]

Aaand my Formula 141 QR hub also started doing everything shown in the video. The driveside cone came loose during a really wet and dirty ride and got filled with water and abrasive materials. Took it apart and regreased everything but apparently the freehub body is basically shot now. Good thing I was planning on a wheelset upgrade anyway.

[@hogg033]

Good to see I have an option for my Roscoe. I just got mine back after blowing out the rear hub (made it freewheel both ways). Trek did a great job replacing it under warranty though. Wondering how many they will replace. Thanks for the videos, cool to see upgrade option on my exact Bike.

[@charlesholland6851]

I have the Salsa Timberjack. Same hub. I'm definitely going to upgrade. Only difference is I may replace the dropouts to use the regular boost 148. But if i9 hubs have that same conversion I may stick with 141!

[@jockobo]

So the stock hub won't be able to accept a thru axel with the proper dropouts on the frame?

[@Northstar-Media]

Think a rear hub will be my next upgrade to my X-caliber.I have noticed the slight engagement slop on technical climbs & had a slight rumble noise from rear hub bearings. I cleaned & lubed them for time being.

[@sangcho5356]

I have been riding xcaliber 7 2021 for almost a year. The rear hub was making ticking sounds and had to bring the bike to Trek to repair the hub. They insisted on the hub being fine but the trueness and spoke tension being the issue. However, when they returned the wheel back to me, the ticking noise was gone and knew that they repair the hub. Probably they dont want to admit the issue because it sounds like to be a general issue with the rear hub on the start line of x caliber and roscoe. I will be replacing the rear hub to Hope just like this guy did.

[@zavir7490]

@@sangcho5356 the rear hub is just shit, imo it is close to a scam, just holding long enough so we don't give the bike back

[@luisweber960]

Great vid. Have the same issue with my Cannondale Trail, and those 141 QR hubs are hard to find... One little thing I saw in the video: the valve is not where it should be in relation to the spokes, LBS should have done a better job there, especially when you expect them to be the experts in the matter

[@ToogyHowser]

Yeah someone else already pointed that out, kinda bummed they didn't do a better job, they also failed to install the provided spacer between the cassette and hub, I had to do that myself. Overall not impressed with them on this. Gonna take the wheel to a different shop that is highly recommended and get them to sort it out. I know the wheel is functionally fine, but I'd like it to be right.

[@bjcresswell]

@@ToogyHowser Hey man thanks for the vid. Definitely folloing suit. Quick question in relation to the above - did the spacer come with the hub or with the cassette? Or did you have to source elsewhere? Appreciate you did this years ago so no worries if you can't remember! Thanks again!

[@hermittranslator]

Got a Cannondale Cujo 1 and it's also running 141 QR Boost (and has the Formula hubs too). Not the end of the world, but it does sure make upgrading the wheels trickier.

[@ToogyHowser]

glad it helped you out!

[@OYeahan]

Why is there this 7mm difference between corresponding QR and TA standards? Is it just that with TA the "locknuts" (as in "O.L.D.", but these are just endcaps with most hubs nowadays) seat 3.5mm inside the rear triangle, and QR "locknut" surfaces seat flush with the frame?

Changed to Hope Pro4 based on this video. The original skewer sucks badly. Hope make a quality skewer too.

I just broke the axle on my backup raceface wheelset. Apparently that axle isn't very strong and probably depends on the through-bolt for strength. Just ordered DT 350's with DT XM521's. I am wondering of those of us who are bigger guys (230) shouldn't cut the ends off a maxle and insert it into the axle prior to putting the QR caps on.

Did you have to shim the brake rotor on the hub out at all so it would mate up with the caliper a little better? I see adapters for the front and rear Hope hubs for rotor shimming is why I'm asking. I too had my my rear hub grinding on me too. I overhauled it, and found the drive side is not sealed up very well, and had all kinds of gunk in there. Its better now, but I know it wont last. My front hub took a dump on my Roscoe this weekend, it too was grinding. When I tore it down, I was missing 1 ball on one side, and 2 on the other. It has NEVER been tore into, that was like that from from Formula Engineering Inc. (Taiwan) if anybody wanted to know. Front hub is a DC511. I want to replace my front hub as well. The grease (what was left in there) was rusty looking. But most likely from dust from the trails getting in there. I'm excited to upgrade my hubs into my factory Sun rims just like you did. Thanks for the video!!!

I could of saved here or there but I just went all out even getting blue spoke nips for $20 more. Ha oh well, its gonna look sickening.

Do i need the hope pro 4 mtb rear hub-boost 148mm × 12mm for my trek roscoe 8

[@zacherytoone9957]

So im gonna pull the plug, and upgrade the shitty formula hub to a hope hub...Any other suggestions or tips for the hope hub? Also, how is the hub in general ..i was looking the hope or the dt swiss 350..

[@steele2223]

Hi. Just wondering why you only replaced the hub rather then get a whole new wheel or wheel set? I have been looking at the same upgrade but once I pay for labour and new spokes to build the hub into my existing rim, the cost is about the same as buying a hope fortus 35 complete wheel. Thanks

[@ToogyHowser]

new wheelset is probably the better option all said and done.

[@abmvt]

Super helpful bro I just for my 2020 Roscoe 7 And I want to upgrade is there anything else besides Hope 4 Since you made this vid ? Found the Hope 4 for 200 bucks but not sure of there is something less expensive that works Also can you recommend riser bar that suit the Roscoe

[@ToogyHowser]

I'm not 100% sure of the alternatives, I know Hope, DT Swiss and Bontrager make hubs that are compatible

[@abmvt]

On ordering the hub On the drop down menu on eBay The last question Is it Shimano /steel / allow or SRAM allow ?

[@carlofogelberg15]

What company Cassette did you use. Does the Cassette have to match with the rear hub?

[@bradshaw3081]

how much does your bike shop charge to do this if you dont mind me asking

[@vadymborys4754]

Can anyone provide alternative hubs and conversion kits? It's impossible to find exact hub model nowadays

[@ryan240sx2]

I see that you have a loose cassette stack, just make sure it's tight cuz it could ruin your freehub body

[@memofo8654]

My question is since you have to replace the spokes as well, which size, brand, modelnumber, etc spokes do you need to complete the hub swap?

[@ToogyHowser]

Sorry I just had the shop do that stuff!! sorry can't help you with that

[@richardwebb3013]

Did you upgrade the front hub?

[@chrismccrimmon6699]

Hey bud. Can you clarify for me. The links in your description, is the conversion kit and the QR end caps the same thing? When I pull them up on ebay and Amazon they look the same. The end caps also state they convert it over to QR. I have a 2019 Roscoe8 with this same issue and trying to narrow down parts so I can order them and fix it. Hope to hear back from you!

[@ToogyHowser]

yes they are the same thing :)

[@chrismccrimmon6699]

@@ToogyHowser Awesome!! Thank you. That is what I thought. I found the hub and the end caps on Amazon.

[@418garcia]

So I also have a boost 141 on my 2020 Xcaliber 7 and that thing is trash. The only thing that worries me is my rear cassette. I only have 9 speed cassette. Would this be a problem?

[@ToogyHowser]

I think so, but I'm no expert haha

[@aarongamata4955]

My gt avalanche 2020 uses boost 141 you think the hope conversion kita used here will work?

[@Mcfc2Rich]

I've noticed in the description you've linked the HUB238 but also QR end caps...do I need both of them or 1? may have missed you installing 2 different sets of caps..

[@ToogyHowser]

just the one set, the HUB238 is for a set of end caps

[@rayr268]

Is there a website showing all the wheelsets or hubs that are 148 that convert to 141 QR?

[@dunneryak]

Overall how much did this cost and was it worth it?

[@gbubbler1]

Hi I’ve recently purchased the same bike 2nd hand, 2 days later the the rear hubs gone. I’m new to all this but going to try to look for an aftermarket one as I don’t have the money to do it brand new... So I’m looking for a hope pro 4 148x12 boost, 28 hole, shimano hg? Not sure what the shimano hg is as I don’t see many there mostly xd!!!

[@ToogyHowser]

yeah for the stock Sram NX cassette you'll need the shimano HG freehub. There are a few other hubs/wheels you can use if you can find them, DT Swiss, Bontrager etc.

[@sushruthravishankar105]

Why did u upgrade it drivetrain to slx. Was there anything wrong with it old on??

[@polrudolf]

Same shitty rear hub on my Trek roscoe 6 . Cant find any better for replacement. My is 141 boost 32 holes for 10 speed. Cant find an replacement.

[@jasoncorazza195]

did you change the cassette? stock is PG and not XG driver?

[@Gamebit450]

Question for you, does the formula hub have the same removable end caps. Curious if you can turn the old Hub into a boost 148?

[@ToogyHowser]

I didn't really look that closely, I'll check it out later today. Not sure why you'd want to do anything with that hub other than toss it haha

[@automotivedistributors9708]

Michael the 141 x 9 QR Formula Hub I have is from 2017 and from what I have seen is the end caps are fixed. I wouldn’t use this thing on any other bikes tho. It’s better as a paperweight!

[@Gamebit450]

Yeah I know but I have the possibility of getting a procal aluminum frame set. And thinking of transferring all my parts from my Roscoe on to that frame. More than likely not what I'm going to do but good to know my options.

[@Drogos79]

Roscoe 6 here. Same hub. Same issue I think. While free spinning, I hear normal clicking but very loud "dry, worn out bearing sound" on top....is that the issue you had?

[@ToogyHowser]

yeah totally :(

[@Drogos79]

​@@ToogyHowser thank u. So much fun when u wanna ride but all shops have 3 week turn around time. If i continue to ride it, am I further destroying just the free hub or both hubs? I am not sure if I should ride it until I get my hands on the replacement or is it more immediate service call? Do you think there is a chance of saving it with cleanup and repacking with grease?

[@lukesanders768]

I have a X caliber 7 2018 and it also uses this hub measure, so thanks for the information and the video!

[@ToogyHowser]

Glad it helped you out!
