Problem Cause? solution
Assembly
too tight • Bottom bracket
shell too wide
• Bottom bracket
shell not faced
• Bottom bracket
shell threads mis-
aligned
• “Stack” of parts is
wrong
Face the bottom bracket shell
to remove all paint and
square the surface.
Make sure the bottom bracket
shell is within tolerance (see
page 6).
If shell is faced and tolerance
is correct, remove the 1.0
mm spacer and reassemble.
If this does not correct the
problem, change the stock
elastomer washer on the left
side to the thinner, 2.5 mm
(available as an accessory-
see your dealer).
If this assembly is loose, switch back
to the standard 3.5 mm elastomer.

Chain-line
incorrect • Incorrect bottom
bracket shell align-
ment
• Incorrect chain-
rings
• Incorrect spacers
on axle
If the chain-line is incorrect,
shifting performance may be
impaired. The 1.0 mm spacers
can be moved from side-to-
side or removed as necessary,
as long as correct bearing
adjustment is achieved. The
spacer arrangement used in
this manual should result in a
chain-line of 43.5 mm.
