    Bontrager Duster question

    Hey all, I just picked up my EX7 and am loving it. I was curious if anyone knows if the hub on the 2014 ex7 Bontrager Dusters is convertible to 142x12? I know the frame is, but just curious if I'd need new hubs to do the conversion.

    I would just upgrade the rims as a whole. the Duster rims are ****.
    I will toast a duster rim in a month.

    The wheel doesn't appear to be convertable. It probably is not worth switching to a through axle, unless you are having some issue that it might fix. I rode my Superfly 100 AL with and without the 142x12 set up, and couldn't really tell a difference.
    FWIW, I have good experiences with all of the Duster / Rhythm rims that I have used, but i am 165 lbs and ride Trail / XC type stuff.

    Completely disagree with this post. I've been riding my Dusters for over 3 years. Not only have they held up great, they're probably one of the easiest and most reliable tubeless ready rims to deal with. Get the proper bounty rim strips and valve stems and you have a UST spec'd tubeless rim in minutes.

    Thanks for the tips, all. So far I like the rims. They are a lot better than the generic ones on my old el mariachi that would go out of true by looking at them! I'm sure they're no Stans or dt swiss or something but for no additional cost they're nice!

    Disagree. Been riding my Duster's for a year. They're awesome and stay perfectly true. (I'm 6'4, 220lbs so I'm putting plenty of stress on them)

    To each their own.
    I have had my bike for a year and on my 4th Duster rim. AZ doesn't have smooth trails.
    The tubless setup on the rims is flawless though. I give them that. Never had a problem with that.
    Never had a problem with my rims off my Carve.

    Then you sir, need different rims. Lol I would replace a rim 4 times with the same model. I would cite possible user error, but I don't even know how that could be possible.

    Wonder if the bike is to blame. I use them on my Fuel.

    I find the conversion business really strange because I have a 2013 EX8 and it says on the website they are already 142 x 12. Is that not right?

    Check with your LBS. I think you can buy different end caps for the hubs for a 12x142 axle. Most all wheels Bontrager/Trek offers come with different end caps to accommodate different bikes. As for the hardware for the frame you would have to order what ever the parts are on the EX8.

    The Bontrager Comp, Elite, and Pro wheels are swap-able between axle standards with new end caps. The wheels on the EX7 have Formula DC32 hubs and do not appear to be upgrade-able to 142x12.

    That is true and maybe Formula is behind the actual hub.

    What I do question is the description on the Trek website says Bontrager sealed hub just as it does on the EX8 which is 12x142. Why would Trek make a completely different hub laced to the same wheel and not just rely on end caps for different speced bikes? From a manufacturing / parts standpoint that does not make sense.

    On a side note I did speak to my LBS a month ago about my stock duster wheels fitting on a friends non 142x12 bike and they said you just need different endcaps. While they did not look up any part numbers to verify it the guy is very knowledgeable and I trust what he says.

    To the OP I would just ask your local Trek dealer.
