    2011 Trek Cobia - 10mm through axle?

    Does anyone know if I can convert my 2011 trek cobia from the QR to 10mm through axle? I have searched a bit, and it seems like its possible, but have not found definitive answers...especially for the trek models. I have hope pro 2 hubs that can be converted, just worried about working it with the frame.

    A regular dropout will take a 10mm thru-axle or a Dt Swiss RWS thru-bolt. I use one and the 9mm RWS on the front dropouts.

    Hey just to answer your question, I wanted to do this to my superfly but I have the bontrager wheelset and they do not make replacable end caps for my hubs (non dt Swiss bontrager hubs) I took everything apart and measured out the end caps that are on it now, and a 10mm axle will go all the way through. I just need to drill out the two end caps that take the quick release skewer and make them a slip fit for the 10mm axle. I'm already running a 15mm axle up front so no need to do front. Hope this helps.
