Concept2 Forum

i ve bought a secon hand 2004 model concept2 model d.
i thought there was only noice coming from flywheel. but there s a noise coming from chain more than flywheel. is it ok? sometihing like vijjj vijjj.

A "sawing"noise from the chain as it goes back and forth is to be expected. I wouldn't worry about it. Compare it with another model D if you want to be sure.

make sure the chain has been oiled and none of the links are too stiff to move free and easy.
