My wife just bought a Raleigh Cadent and it has quick release hubs. We ride a lot with a trailer with our toddler, but the trailer hitch mounts to the rear axle. I tried putting the hitch on the QR axle, but with it on there, it is too short to fit all the way back into the dropouts. Is there a longer QR skewer you can purchase, or do you have to change to a solid axle like on cheaper bikes? Also, if there is a longer one, is a skewer strong enough to support the weight of the trailer and child?
