My Merlin Extralight is 20 years old, is in outstanding condition, and I just noticed the right crank arm is cracked. I "think" the crankset is American Classic. It's running 39/53 chainrings and a 7sp freewheel (remember those?). I don't mind spending $$ for a quality lightweight crankset, but I'm concerned about compatability with the current sets out there.
Can anyone recommend some lightweight choices? Thanks.
