Just got a new bike a while bike so I am parting out my old bike and putting some of the parts on my wifes trek marlin.
The crank I am putting on is an SLX crank (3 x 9). The crank that came on the Marlin is a Shimano M311. Since the marlin is a 29er, her stock crank has a smaller chainring set than is on my SLX crank (that came off of a 26" bike). Can I swap the chain ring set from her stock crank to the slx crank?
Any tips on doing this?
