    ABP convert from 135mm to 142mm x 12mm - what is invovled?

    I have a 2012 EX8 and will be switching from Dusters, 135mm setup to XT wheelset in 142 x 12mm.

    I have the Rockshox Maxle on order and the wheels will be coming tomorrow.

    What is involved in changing the drop-outs from the 135 to the 142mm setup? Looks like just un-bolting the old and bolting on the new larger drop-outs? Is there anything to look out for or be aware of?

    What should I expect to pay for the 142mm drop-outs from my local Trek Store?

    Thanks.

    It's as simple as changing out the bolts lol. I can't remember if there is a torque setting on it or not. But there is nothing to it. Probably around $30-35.

    I've got the Rockshox Maxle and the drive side hanger. It appears that I only need the two outer nuts and the left side insert? Do you know if the outer nuts are the same?

    I'd like to say they are but I can't remember 100% certain. I will watch the trek video, but for some reason it is not working right now. I will post an update if you don't find out from another user.

    Both outer nuts are the same in 142 mode, also is the same nut used on nondrive side in 135 mode. For 142, the bike will use just the two dropouts and outer nuts. For 135, it the different dropouts with the big nut on nondrive and cap/insert on driveside.
    Worked at Trek/Fisher dealer 2008-2013. Only a little biased.

    Thanks for the details. The local Trek mechanic was trying to find what parts to order.

    I have the 135 setup right now so I already have the brake side outer nut.
    So I need one more of these now for the drive-side outer nut.

    I have the derailer hanger for 142 and the Maxle.

    I will need the brake-side dropout.

    Thanks for the details.

    Tell your wrench to check dexter under services-technical for the suspension diagrams with part numbers. FYI what you need is W304640 and W301803. You did get the extra long Maxle, yes? The standard length 142 Maxle doesn't work with ABP.

    Thanks for the part numbers. That will make it much easier. And yes I got the longer ABP Maxle. Thanks again.

    This went fine. FYI the two outer nuts are the same in 142/12 setup. I just had to get the two inner dropouts and the one additional outer nut.

    Hello SpeedStarr, I just got a 2013 Trek Rumblefish and and to install my Rohloff on it, thus I need to do the opposite conversion that you did (from current 142 Maxle to 135 QR).

    With you experience do you know what parts do I need? Maybe the parts you took off your bike are what I need, are you interested on seeling them.

    Please tell me if this is not the right place to post this request! Thank you!

    Trek sells a kit that has everything you need except for the extra long skewer. Part #427344 for the kit and Part #W306634 for the skewer.

    Hi Blunderbuss, thank you for the precious info, I'll look for those parts, the problem is the Brazilian distributor that is not that agile, this is why I wonder if a fellow owner that switched from 135 to 142 would have these parts idling on the shelf...

    I already have a skewer from my kid's trailer, it's 160mm long (with the nut already in place), do you think this is long enough?

    Anyway I'll ask for the official support. And thank you for your help!

    Correct. You need the slightly longer, Trek-specific Maxle thru axle.
