CYCLE PARTS
FRONT WHEEL RIM
• Using a dial gauge, check that the radial (A) and axial
(B) eccentricity of the rim (2) does not exceed the
specified limit.
Excess eccentricity is usually caused by worn or
damaged bearings.
If after the bearings have been replaced the value is
not within the specified limit, replace the rim (2).
Maximum radial and axial eccentricity: 2 mm (0.0079 in).
