A necessity.

  • Familiarity: I've used it several times

Needed to convert a front wheel from 15x100 TA to 12x100 TA for use on a different CX/gravel bike. Super easy to install; but requires a little effort to remove if you need to swap back & forth.

Unanswered Question

Is there a spacer that comes with these? Does the thru axel make direct contact with the bearing? I'd be converting from a 12mm thru setup.

easy to install

easy to put on, no issues on a couple of these now.

Easy conversion to 142 thru axle

  • Familiarity: I've used it once or twice and have initial impressions

Works great, but has to be used with DT Swiss hubs that are compatible (listed on DT Swiss' website). Super easy tool-less installation!

They work but a little pricey.

Big pro is that if you were running a qr skewer of some sort you can easily convert your wheels to 142mm. These will not the solve problem folks are encountering when trying to jump to the new 148mm boost standard. These adapters will work on both 142mm and 148 DT boost hubs but they will not make a 142mm into a 148mm. Your will need to buy a new boost hub for that.

what option do I need for my dt350 rear mountain bike hub? I currently have 9mm qr and need to go to 12x142. Im running shimano 10 speed.

This conversion works on both DT350 and DT240 hubs. Be aware that end caps are freehub specific. You will either get Shimano/Sram (Older 10spd) or the Sram XD (Newer 11 and 12 Spd)
*End cap kits do not include the thru-axle.

Would this allow me to convert Shimano RX31 from QA to 12mm thru axle?

Sorry, these are DT swiss hub spacers.

End caps make it easy

I needed to convert a set of wheels from QR to TA...these made it simple.

in order to convert DT240S QR hubs to TA do i need the TA as well as the end caps?
