    Bontrager hub conversion.... Desperate need of help!

    First off I would like to say hello and this is my first post...

    I just purchased a used wheel set off of eBay (for a steal might I add) with bontrager hubs. The rear is a 142x12 and I need to convert it to a 135x10 thru bolt Qr for my 2013 Trek superfly Al. I wish I new what hubs they were but it looks like the DT Swiss end caps would work. Does anyone know what kit I would need or if it would work?

    Trek probably makes a conversion kit for this hub. Do you know the wheel or hub model? A Trek dealer could be of assistance.

    Thanks for the good advice so far but I forgot to mention I talked to my local shop and they even emailed trek with the pictures but they said they needed a model number...
    Which I can't find anywhere on the hubs. I can always take it in but I kinda wanted the to save the money and do it myself...the seller in eBay didn't specify what hubs he used when he pieced them together...

    Does anyone know where I could find the model number?

    you might be able to take the cassette off and run the part number that is on the freehub, maybe that will give you a cross reference as to which hubs that freehub came on.

    Hub is made by Formula. It's heavy, loud and has slow freehub engagement. I like Bontrager stuff generally....but this is not one of them. Their RXL Scandium rims are light and spin-up fast, though.

    No conversion for the hubs, but trek has the ABP axle conversion kits for about $50.

Desperate need of help!-image.jpgBontrager hub conversion.... Desperate need of help!-image.jpgUnfortunately My 2013 superfly doesn't have the ABP drop outs. But I took apart the hubs (somewhat) and they look like they would be convertible... I took some pics and found the free hub part number if it helps at all

    A guy on eBay makes a custom axle reducer, for 10x135 conversion. His seller name is mtbtools. See if his billet adapter works, for your application. I bought his front axle kit, reducing my 15mmTA FCC Bontrager hub to QR and it works PERFECTLY:

    Does anyone know if it would be possible to get 135x12 end caps for these hubs? Then I can run that billet reducer axle. Thanks for all the help so far

    I had these exact setup and ran into the same problem. Bike shop wanted 95 in parts and 25 for the labor. I got them cheap like you and ended up with a rebuild as I found out why they were a bargain.
