Bike year: 2012.
model: EC250-e.
mods: Rad braces.
Gearing: 13/52.
Top speed: ???
what kind of ridding do you do: Woods, slow stuff mainly.
Question: with the current gearing the chain has eaten through the chain guide, will a TM designs (they say up to 3t extra) fit it &/or do I need to revert back to a 50 & possibly fit a 12t on the front for the same effect?
Robs.
