    Mojo SL rear wheel issue

    Today after work I was able to get out and get a nice one hour ride. Towards the end of the ride after a short downhill I was climbing and on the rear cog the chain shifting on its own. I put up with it and did another short downhill at speed. Then when I started to climb again the ghost shifting continued and it was frustrating. I stopped at the top of the climb got off and looked at the rear derailleur which looked ok. I lifted the seat a little to spin the wheel and the wheel fell off. The quick release was completely loosened. I feel very fortunate that it didn't come completely off on a downhill. Has anyone had this happen to them on a Mojo SL. This weekend after my ride I took off the rear wheel and cleaned a greased the quick release. I tightened it but I am always hesitant to put too much pressure on it because of the carbon frame. Is there a rule as to how much to tighten. This is the first time the wheel has ever come loose.

    Scary!
    I've been told as a rule of thumb that if it leaves a mark in your hand from tightening it, it's sufficient pressure.
    Don't worry about over tightening it for the sake of the dropouts - you can't hurt them that way.

    Last year (I usually ride to the trail head) I was on my way for a good session if climbing/descent with my FR rig and before the climb I always stop at the park at the mountain's beginning to stretch out a bit and setup suspension. So I arrive, stop close to a bench, get off the bike and lift it by the saddle to lay it against the bench and then the rear wheel just stay right on the ground, with the drop-outs in the air... I've since add the QR check to my pre/post ride checklist and to the list of mid-ride verifications... That was scary knowing I wasn't planning at first to stop to stretch out, but to do it later after a good heat up climb...

    I had something similar on Sat. Did some brake work and didn't tighten the rear properly.
    I'd rather err on the side of too much pressure than not enough. I don't think you could generate enough pressure with a QR handle to damage the frame, the handle would probably break before the frame gets any damage.

    Make sure your qr's are tight kids!

    Don't care about tighten too much. There are stainless steel inserts at the droputs that won't let damage the carbon with the pressure of a skewer. I use a 135x10mm Hadley thru axle on my SL, and i keep it tightened way much that any skewer can resist. Never had any issue.

    You could switch to a DT Swiss RWS skewer. The ratchet down instead of cam, letting you place a lot more force on it than with a traditional skewer. Alternatively, you can see if your hub can accommodate a through bolt.

    I had the same problem along with an annoying popping sound. I got tiered of check if my QR was open, so I just got a new one (sorry I donít remember the brand) and all my problems were solved.

    Send a note to Scot or Hans. I had the exact same issue w/ my QR and they promptly shipped a new one. No issues since it's been on there.

    I recently added the 10mm DT Swiss RWS to my Mojo SL rear & it works beautifully, stiffens up the rear triangle and super secure , )
