Hadley Hubs
From Pvdwiki
Hadley Rear MTB hubs are some of the best in the world. Dura-Ace, XTR, and Chris King are all of paramount quality, but only King is as flexible a design.
A Hadley Rear MTB hub can be converted to any of these configurations very cheaply:
10mm QR 10mm Through Axle 10mm Ti Bolts 12mm Through Axle 14mm Through Axle 15mm Through Axle 16mm Through Axle 17mm Through Axle
This saves the rider a lot of money as he/she moves from one frame design or option to another.
