Q. I'm experiencing chainsuck or chaindrop on my Sugar, what should I do?
All mountain bikes are prone to experience chainsuck or chaindrop. In most cases if you are experiencing these issues on your Sugar, they can be remedied at your local Gary Fisher dealer.
Here are some of the common causes of these issues and possible solutions. It is important to remember that a bicycle is a machine, and this list attempts to address mechanical problems. It is not likely that occasional shifting issues will disappear completely from any bicycle.
Derailleur adjustment
Drivetrain maintenance (dirty or worn chainrings, un-lubricated or worn chain)
Component incompatibility (mismatched chain, chainrings or front derailleur)
Shifting habits (unplanned or high tension shifts will cause problems)
Inclement/severe riding conditions (increases occurrence and may lead to ongoing shifting problems on any bicycle model)
Some models of Sugars shipped with incompatible chainrings on the stock Bontrager crank. The offending rings can be identified by the 'V3' stamp on the middle ring itself. This ring can cause or add to shifting issues and should be replaced with the 'V5' version chainring. These replacement rings can be obtained through your local Gary Fisher dealer at no charge.
Frame alignment
The first six items on this list can be addressed by a local Gary Fisher dealer and by improving shifting and maintenance habits.
If these have been addressed and shifting performance does not improve then you may need a frame alignment evaluation. Alignment should be checked by an authorized Gary Fisher dealer who can work with our Technical Services department for a solution. The likely solution is for an authorized Gary Fisher dealer to install Adjustable Chainline Bushings that allow the dealer to tune the alignment of a Sugar.
