The day has finally come for upgraded axle adjusting blocks to be available for SurRon and Segway e-bikes. This unique design allows the left side of the axle to be bolted in removing the need for Allen keys to remove the axle. The Warp 9 design also features captive adjustment bolts meaning when you adjust the axle adjuster the axle will move precisely with the adjustment giving precision chain and axle adjustments while having no play between bolts and blocks. The black anodizing and defined markings on the axle blocks should also help with precise axle alignment over the OEM design which is hard to read the markings on. Features Titanium captive adjustment bolts, 10 mm Left side block stays in place and will not fall out when you remove the axle Titanium axle bolt backing plate is cut to insert into the axle which means you never have to carry an Allen wrench again to remove your axle. All you need is a 17mm wrench Works with OEM Axle and Warp 9 Titanium axle Fitment Sur Ron LBX Segway X160 Segway X260 Talaria Sting E Ride Pro-S E Ride Pro-SS Talaria XXX Note: This does not work with KO Moto Swingarms.
