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.

Is this one of the early Merlin's that had a built in bottom bracket ? If so you might be stuck with square taper cranks.
That's not so bad, lots of square taper stuff on eBay. Might even find a match to your original crank.

Good luck bill

What's the BB on that? OK condition?

Assuming it's a JIS (Shimano) type square taper, I'd be looking for a 9 speed crank in good or NOS condition. A 9-speed chain will work fine too on that 7-speed cluster (I know).

You can also replace the bottom bracket with a different compatible version if it is not the proprietary BB that Merlin produced. I really like the late 2000s Shimano Hollowtech cranks. The 9 speed DA cranks had issues with pitting and I replaced all mine.

My Merlin does NOT have the proprietary BB. Looks like IRD and FSA make some nice classic looking cranksets. Might go with a track crank since here in S. Florida there's no climbing, thus no need for a bunch of gears. Save weight and gain simplicity and clean appearance. Thoughts?
