BB386/PF30 Go/NoGo Gauge

This BB386/PF30 Go/NoGo Gauge is an indispensable tool for checking if your frame meets the BB86 Press-fit tolerances. Precision-machined from 304 Stainless Steel.

Diameter specifications: 45.95/45.98mm

Material: 304 Stainless Steel

Note: A frame that does not fall within this band of tolerances is not necessarily unusable. However, one may experience degraded performance such as bearing roughness, premature failure, or creaking if our Revolution Bottom Brackets are installed in an out-of-spec frame.
