I apologize in advance if I mix-up some lingo, I have almost no experience in fixing bicycle drivetrain.
Previously I had Comet CKM-7159 as crankset (I managed to find this datasheet that seem to describe it pretty good - datasheet)
Long story short, pedal track on the left crank got completely destroyed. Since it's a two-piece crankset (or I just have not enough muscles to detach left crank from the spindle) it looks like I need new crankset .
Based on my filters:
- crankarm length from 170 to 175 mm
- bottom bracket diameter - 24 mm
- crank gearing - 1
- chain gearing - 11
I get exactly 7 sets: Search results :(
I'm not trying to spend a fortune here, so I look at the cheapest option on the list: https://www.bike-components.de/en/Shimano/GRX-FC-RX600-1-Crankset-p72011/?o=200945-black-175-0-mm-40-tooth
It looks okay to my non-trained eye, I think it should work. However, when I look at the description of my bottom bracket, I see this interesting bit:
Only for cranksets without clamping screw on the left crank arm (NBD)
And as far as I understand my main candidate for new crankset actually has this clamping screw.
Do I interpret this correctly and this set is indeed incompatible with my bottom bracket? Or it will fit after all?
Also any other constructive criticism of my though process is very welcome, as I said in the beginning, I have almost no idea what I'm doing.
