Description
- R2V 1974 > 1980 ATE 38 mm ATE CALIPER
**Caliper repair kit with a single 38mm diameter piston, for bikes built before 09/1975.
40mm calipers have ’40’ stamped on the outside of the caliper body.
If your caliper is unstamped it will almost certainly have a 38mm diameter piston, but please measure your piston diameter before ordering!
**This upgrade piston is made from anodised aluminium and will not rust and seize like the original is prone to do.
