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).

Assembly 
too loose

• Bottom bracket 

shell is too narrow

• 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, add an additional 
1.0 mm spacer (available 
as an accessory- see your 
dealer) to the left side and 
reassemble.

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.
