COMPATABILITY -CHAIN DAMPERS

The 

STFU chain dampers

 wrap around and contain the chain on your mountain bike, limiting how far 

it can move when riding over rough terrain. This results in a quieter ride as the chain is no longer 

slapping  against  your  frame  but  also  increases  chain  life  by  preventing  it  from  flexing  sideways, 

which can cause the chain to wear and flex too much over time, decreasing shifting performance.

Gearing:

 The STFU chain dampers are designed to work with 1 X setups only. This means if you 

have  more  than  one  front  chain  ring  the  system  will  not  function  as  designed.  We  have 

tested using a single larger unit of the TRAIL set with 2X setups (2 front chain rings) and it works 

on some bikes. A

t this stage we only offer each system as a set. 

Specific Applications:

•1X gearing for trail bikes up to a 52 tooth cassette 

- use the TRAIL set

•7 speed DH gearing with cassettes up to 26 teeth 

- use the DH-07 set

•10+ speed DH gearing with cassettes up to 32 teeth 

- use the DH-10 set

Fit: 

The STFU modules attach to the top side of the chainstay. For this reason they are generally 

only compatible with bikes that have ‘traditional’ chainstays positioned between the upper 

and lower portion of the chain. The modules will generally not work with ‘elevated’ type 

chainstays that sit above the chain but some users have been making them work. However, we 

take no responsibility if you buy and they do not fit.
