humm....just trying to find out what number of chain is usually used on Mountain bikes....#41 or #35.

Monstrobolaxa; I'm not familiar with the numbers you are using, can you provide more details as to their respective sizes and I can tell you which is the one you want.

Well actually the numbers seem to be the sproket thread...

The chain from a high end mountain bike (9 rear sprokets) has a pin length (overall width) of 6.8mm and a pin spacing of 12.7mm.
