Got a new fork for my road bike, happens to be a track fork with a narrower dropout. The axle I have (approximately 9.5mm) is just slightly too large for the dropouts. I have looked online for a slightly smaller axle but all I have come up with are skewers, apparently around 5mm. I haven't used a skewer before but it looks like it may come with a hollow threaded axle. Anyone know the circumference of a hollow threaded axle that might come with a skewer? Sources for purchasing skewers or axles? Do they generally come with caps/bearings/locknuts that would fit the hub such as what was on the 9.5mm axle and the hub? Comparative experiences? Thank you and happy holidays.
