Warp 9 Surron Lockdown Axle Blocks

Axle blocks that take the guesswork out of chain adjustment and rear wheel removal. The steel axle bolt backing plate is cut to insert into the axle itself, which holds the axle against turning, so the wheel can come out with a 17mm wrench alone rather than a wrench and an Allen key.

The captive adjustment bolts are titanium and 10mm. Because they are captive, turning the bolt moves the block both forward and backward with no play between bolt and block, which makes small chain adjustments repeatable rather than approximate. One block stays in place when the axle comes out instead of dropping into the dirt. They work with the original axle and with the Warp 9 titanium axle.
