Common questions
Can I use a conical bolt where a ball seat is required?
No. Conical and ball seats are not interchangeable, and the wrong shape will not clamp the wheel properly. Match the seat your wheels were built for.
How do I know the shank length is right?
The shank must match your wheel and hub thickness so enough thread engages. This bolt uses a 40mm shank; compare it to the one you are replacing.
