Bontrager Mustang 29 Wheels – as fitted to 2012 Superfly AL Elite

Does anyone have any bad experiences with these wheels? My first ride (usual route) on my brand new Trek ended after about half an hour when it threw me off! I could have gone into a rut, or hit something (but we couldn’t find anything – and it happened so fast) but I’m wondering if the wheel just failed in some way?

Eh? Are you saying your wheel buckled/broke? Post not clear?

Sorry – my first ever post in a forum! Yes, the wheel is well buckled! I wrote the post and I’ve been trying to add a picture of the wheel – hopefully be on here shortly…

Properly pringled. Did you hit a rut or rock?

Hi,
Looks familiar! First ride on my Anthem X 29 with Hope wheels same thing happened! Very baggy wheel build! Claimed a new rim under warranty.Yeah,threw me off bike and didn’t hit anything! I would contact Trek and explain situation.Make sure I tensioned all the spokes before my next ride!
Thanx

I wasn’t aware of hitting anything! Walked back up the track to see if there was anything I hit but didn’t find anything. There were plenty of ruts (Ridgeway in Oxfordshire!) either side of the track I was on but I didn’t get the usual ‘wobble on’ in that situation – I was literally riding along one minute and then over the handlebars and on my back the next…

Result! After they checked over the rim and saw what looked like a crack, the LBS have advised me that Trek will be replacing (and probably upgrading) both wheels under warranty! 😀

Bought a Trek/Gary Fisher x-caliber 5 weeks ago, which came stock with a Bontrager Mustang 29er wheelset. I have had rear spokes repeatedly get loose. Not a little loose, rattling around loose. I have been diligent about checking/retightening and keeping the wheel true. I have had it checked by the LBS a couple of times. Most recently a rear spoke was broken. I am new to MTB-ing (long time roadie) and am a cautiously aggressive rider, keeping to an intermediate flow trail. My experience with MTB-ing is limited, but this seems a design or quality issue with the wheel. I had a similar issue with Bontager road wheels in the past. I am 6’1″ & 178 pounds, so I don’t think rider weight should be an issue.

Yeah – most Trek mtb bikes have a max rider weight of 300lbs – so no issues there! Trek are pretty good with warranty claims, so it may be worth pursuing that. I got upgraded to Rhythm Comp’s – bonus…

Did they warranty the tire for you? This exact thing happened to me today. 2nd ride on my new bike on an easy trail. Don’t believe I hit anything. Tire looks exactly the same…..

Trek replaced both wheels for me. My LBS inspected the wheel and noticed it had failed where the valve comes through the rim…

Can we assume the tyre unbuckled itself as soon as it was fitted to a new, straight rim?

The wonders of modern technology…

Ah – 29er wheels – they do that apparently!

Seriously though – either you hit something or the wheel is faulty.

Wheel with tire:) Yes my wheel/rim is bent and my tire looks wonderfully straight when off and on a new rim:)
