This 5mm rotor spacer and bolt kit turns any old 20mm front hub into a Boost DH compatible hub.
The spacer is machined from 6061T6 aluminum and is supplied with 16mm long stainless steel bolts.
The only difference between old 20x110 spacing and the latest Boost DH 20x110 is the rotor spacing and spoke flanges. Adding this rotor spacer brings the rotor inline with the wider brake spacing found on Boost DH forks. The spoke flanges remain centred, meaning there is no need for any re-dishing of the wheel.
These spacers are made to order. Please allow enough time for your order to be made - usually within one to two weeks, depending on demand.
