The chrome wheels have been tubeless since March 2019; and the silver-painted wheels have been tubeless since May 2018.

If you have older, tubed wheels or are fitting tube-type tyres you will need 155/165 x 15 tubes – available with either metal (race) or rubber (road) valve.

This wheel is laced to the outer part of the rim only and so does not require a rim band.

Disc wheels were standard fitment with wire wheels as an optional extra.
