Hey guys. I just stripped the left crank thread on my Mercier Kilo TT. It's a Truvativ Touro crankset and I'm looking to buy just a left crank arm rather than replacing the whole crankset.
What should I know about compatibility with the bottom bracket etc?
Is there a reason (other than long term durability) not to go with a cheap arm from the interenet (i.e. http://directbicycleparts.com/produc...r2125-qc53.htm)
