Is there a hub that uses standard Shimano axles so that hollow axle, and thus quick release, is still possible to do?
All that has to match is the thread diameter and pitch and the axle has to be long enough to match the dropout spacing. The "curvature at the ends" is of no matter. As a guide the correct axle length for a qr hub, it's 10- 11 mm longer than the dropout spacing so a 126 mm frame uses a 137 mm axle and a 135 mm spaced frame uses a 146 mm axle. As noted, the axle shouldn't be too long or it will protrude beyond the dropout faces and keep the qr skewer from tightening on the dropouts properly. As also noted a too-long axle can be shortened rather easily but a too short one can't grow.
