DT Swiss | Converting BOOST 148 to BOOST 141 | Replaceable endcaps 

Happy to help! This is exactly why I made the video 😁

No problem! Mine is hg but I think it can be either ordered with any of the two, or retrofitted. Mine are 30mm wide on the inside. But it comes in many widths for your specific needs 😊 but it seems that 30mm fits everything from 2,2-2,6 tyres 😁

The exact one I show in the video

There's a world of opportunity out there 😎

i have a Rosco 6 and thought the same,i was thinking why would trek make a 141 boost thats so dumb.

Same here, actually regret buying my xcaliber due to having similar priced bike having thru axle 148s

Same. I thought I can only use the shitty bontrager wheels.

right?! then after watching this i was like wait thats it?

I`m glad that you appreciate the effort :)

That is correct.

Why is that? Why won't you replace your wheel using the 12x148 hub with end caps as suggested in this video?

Nope, nothing changes compared to using a 141 wheel 😄

I think they're supposed to be the same. But don't take my word for it 😬

It was pretty hard to find them at first. think I got them at like, chainreactioncycles. But they might have been subject to a change in the parts number maybe?

Haha yeah it would help alot!

Hmm I have no idea! Maybe take it to your local bike-repairshop!

Hmm, That's odd, seems strange that they'd make their axles too weak. But yeah, it seems like you could put a maxle in to strenghten the whole thing.. Couldn't hurt trying!

Your question kind of doesn’t make sense. 9x141 QR is not a standart mount. I’d say most common are 5x135QR (older bikes/ cheaper bikes), and 12x148 (newer bikes, often a bit more expensive). As I said your 9x141QR isn’t nowhere near standard dimensions, I don’t think you’re going to find fitting endcaps. The endcaps in the video turn a 12x148 TA into a 5x141 QR for example, or a 12x142 TA into a 5x135 QR. The endcaps basically are narrower at the end so that a 5mm QR can fit through both ends, and the weight is being held by the endcaps and not the QR axle itself. This „patent“ (I think you meant these endcaps?) works for all hubs that support interchangeable endcaps. A few examples would be Hope, and DT Swiss (he mentioned more at the end of the video).

Hmm, are you sure? On quora and in few other places I found information that 5x141 vs 9x141 makes no difference. Some comment were stating that actually that "9" in 9x141 is kinda made up, and all should fit. Currently I have Shimano FH-MT200-B rear hub. What does usually that first digit in hub size represent?

This exact feeling is what motivated me to make this video 😂 Happy to help!

Hello! I have a trek X-Caliber 7 (2021) with Boost 141 QR 5mm hubs. I want to replace the rear hub of it. What DT Swiss hubs is compatible for my trek?

@@whodafakru7668 I think most of the hubs are compatible but you have to get one called boost148 with replaceable endcaps.

@@Mikesbikerides are the DT Swiss replaceable endcaps compatible with all DT Swiss boost 148 hubs?

@@cristofer2433 At this time I do not have any information about that, sorry! Isn't it so weird that they don't just provide a good clear list with compatible hubs?

Thanks dude! Hmm not too sure.. I guess they should be the same but not 100% sure

No idea, sorry!

Not entirely sure, but I think they do..

No problem happy to help! For sure a good upgrade! Haven't had a single hiccup with this wheel, strong as hell but heavy!

You wouldn't. Gotta have a 148 wheel and put on endcaps that make it 141

Thanks! Happy to help where I can :)

That's awesome to hear! Can't fathom why they stuck so long with the boost 141 on this bike. Luckily they seem to be moving away from that now with the new roscoe, and hopefully the x-caliber will follow. Can't find any good wheel in 141 size.

Not that I'm aware of! Dt, nukeproof, hope and some others can!

Thanks mate!

Hehe good luck with that 😛

@@Mikesbikerides thanks for silly comment ... U couldnt see video? There is a solution and already is also what he shows right ... so very weird u comment in such a way to a video that shows it... maybe u didnt see it HAHA good luck with your "logic" in future 😁

I have no idea where you can find them in your country. But the number I show in the video is used world wide so search for that 😁

Never tried with that driver but I imagine they should be the same?

Gotcha, my model and some others have come with microspline. I was hoping yours had but I seen previous comments. I believe this will be another workaround that I and others will have to solve. They don't make qr end caps for microspline.

Not sure you can do this conversion on shimano stuff. Here I am fitting a boost148 wheel into a frame that is narrower, boost141. If the HUB of your wheel is boost141 it's likely to be quickrelease and is built totally different with cup and cone bearings

I don't think they have replaceable endcaps..

That is a whole other ball of wax I have yet to mold 😂 took some time to even figure out what torque caps were and if I needed them 😅 Sorry but I have no intel there!

Hmm I'm not sure about that one! Would advise asking a certified dt swiss dealer 😄

I have no idea about the number right now, but it's shown in the video actually :) Good luck with the upgrade :)

I believe it will. It comes in hg and microspline so make sure to choose the correct spec. I have run two different cassettes and they're both 10spd

Thankyou! Happy to help 😌

maximilian mager did you ever figure out if there work with the xd driver?

Good to be able to help 🙂 Hope it works out fine!

Haha yeah but before you understand how easy it is, it's kinda confusing 😩 Violence always helps in mechanics 😂

O problem buddy! 😊

No problem! Thanks for the sub! :D

I don't speak italian, but thanks for commenting :)

Can't say for sure. But I think they use the same system on most hubs..

HG :)

Hmm which year model is the x-cal?

@@Mikesbikerides 2020. But I just figured out I didn't get the adapter for dt swiss microspline.

@@Mikesbikerides probably for hg or sram or somryhing. :)

@@hargibi oh ok. Well it's very difficult to offer any kind of insight when I haven't seen the stuff 🙃 hope it works out 🤩

Did you ever get this to work? Thanks i also have a microspline driver

I actually have no idea, sorry! :)

Happy to help!

Haha bike viking 🤩 No problem :)

It should be yes! But not all wheels can do it

Happy to help 😃👍🏻

Wouldn't have any idea 🧐 I just measure by eye I guess 😆

Exactly! They make the big hole smaller and add flanges for the qr dropouts

No problems! Happy to oblige :) Say hi when you see me! :)

Gött att du fann denna videon informativ! 😁

Yeah they’re probably the same on my x-caliber.. I was looking at nukeproof horizon v2 with 102 engagement points but cheaped out for now with dt swiss. Really nice upgrade though and proper sealed bearings, not that cup and cone BS😁 And yes, violence always helps 😂

Boost 141 had a spacing of 141mm. Non-boost 142 had a spacing of 142mm. But most 142 hubs have through-axle which will not fit the 9mm dropouts. and if you replace the endcaps on a 142 through-axle hub it will become a 135mm spacing. With 9mm axle. So confusing!

Nope! Or.. maybe by hacking the endcaps and sawing them off by a couple of mm.. But I wouldn't recommend it.. Or maybe there's an aftermarket kit for that?

Happy to help! 🤩

That'll be a great update for sure :)

@@Mikesbikerides for sure as I can feel that horrible vibrating sound coming from the rear hub.

No it will not fit. If the wheel is a 141boost it doesn't even have that type of cap 😊

@@Mikesbikerides thanks bro

Hmm I just used whatever came with the wheel and didn't look twice.. 😮😂 Sorry I can't be of more assistance on this! Happy to help with the rest though 🤩

190,240 and 440 are the models of the hubs from DT SWISS, not the disc size, if that was your question.

Don't know.. But it's more work changing a hub..

Definitely gonna have to do a review of this shortly.. It has been performing great, has taken alot of beatings but not buckled once! It is a 24 engagement point hub so not the greatest sounding hub, but still alot better than the stock 15 EP..

Boost 148 with adapters will make it a boost 141. But 1mm is not much and might work. Can't promise a good fit though

@@Mikesbikerides I will try and let you know how it runs.

@@mihkelm.6853 Looking forward to hearing about it :)

No problem :) I needed a video like this when I was buying a wheel!

Not really sure.. But if the frame is through-axle and not quick release, it would be either a 142mm or a boost 148. Quick release exists in 135mm and boost 141. You can take a 142mm non boost TA wheel and turn into a 135mm Quick release. Or you can take a boost 148 TA hub and turn into a Boost 141 quick release. I think you use the same endcaps for both. If your hub has an axle with threads on and a small hole going through it, and cup and cone bearings, it is either a 135mm or 141mm. The 135/141mm dictates the spacing between the chainstays, not the length of the axle. Hope this helps.. haha so confusing

@@Mikesbikerides hi, I know what the sizes mean. I measured the axle yesterday. It’s a boost 141. The frame and axle are both TA (of course). So they just placed a 141 boost wheel in a 135mm frame….😩. The only thing I can’t explain is why the rotor is so close to the brake mounting points. The Shimano disc has less then a mm play. The floating Hope disc has this connection bush and is thicker. It rubs against the mounting points. Is it possible for you to measure the length of the 141mm and 135mm end caps?

The 148TA -> 141QR option is als possible… I have to find a way to identify the hub itself… no measurements on the DT website

They would be replaced the same way but I don't have the parts number I'm afraid!

@@Mikesbikerides i asked DT Swiss just to be sure and will give you the part number if you want to update your description for others like myself ;)

No problem at all!

Happy to oblige 😁

Thanks! ☺️

I'll take your word for it :)

No problemo! 😊

No problem! :) happy to help!

@@Mikesbikerides what do you think of the hub now that you've had it for a couple of months? 😁

@@MathiasMassias Nothing bad to say about it :) Haven't had a single problem and the wheel as a whole has held up to everything I threw at it :)

@@Mikesbikerides awesome!! Thanks again mate.

I have no idea, sorry!

@@Mikesbikerides Thank you nevertheless.

and my bike is 12 x 141mm! sorry forgot to mention this!

All QR skewers are 5 mm in diameter I believe :). I don't know any bike that has 12mm axle and QR though? The axle is usually 10mm and hollow, so that the qr skewer can go through it.. There are bikes with 142mm and through axle though!

@@Mikesbikerides Thanks Mike. and yea you're right! I just had a confusion because I went to my LBS and they said that these were for 9mm thru axle. I was disappointed, however, I did some research and found out that 9mm axle is only for the front. Then I saw your video and asked, and you confirmed, plus another amazon review also confirmed. So piece is arriving Monday brother! Excited to get rolliiiiiiin' thanks again for the help 👊🏾👊🏾👊🏾

@@luisarodriguez9136 Haha yeah axle standards are weird! The axle is 9mm front and 10mm rear, and the skewer is 5mm.. then we have 110mm and 115mm front axles which can be 15mm or 20 mm thick. and rear of course with the 135, 141, 142 and 148 :D They should just decide on one and go with it.. Not to mention bottom brackets and crank standards..

@@Mikesbikerides I know bro. Trust me! And for a new rider like myself is a bit overwhelming, but once you know your bike, you can learn easily about others! I was waiting for the piece to arrive to reply. It just did, and it works PERFECTLY bro, so soon I'll be on wheels again! thanks again for the informative video, truly truly helped! Greetings from California!

Glad att kunna hjälpa till 😊

I would advice against it. 1. You'll possibly ruin the frame 2. 142 is getting more rare, why upgrade to something that's soon obsolete? Getting a 148 wheel and using the endcap trick will work great on your qr frame until you get a new frame with 148. The one downside of the qr wheels is their bearings which are cup/cone. The qr mechanism itself is not particularly weak.

@@Mikesbikerides 👍🏻 I just found a Nukeproof neutron v2 wheel/148 for great price & adapters. Ty for the advice!
