Title: 165 mm cranks for Scalpel Si?
Post by: Joda55 on April 18, 2026, 04:36:52 AM

I have knee problems and want 165 mm cranks for my Cannondale Scalpel Si WC 2019.
Currently 175 mm Cannondale SI 8 bolt crankset.

I could just buy Hollowgram cranks and put on current spindle but they are like 300 eur a pair.

Does anyone know of cheaper alternatives?

Chainline is 55 mm
BB shell: 46 mm ID, 83 mm width

I think I found a potential budget lifesaver for your knees. Check these Senicx FM3 in 165mm:

Thank you but I don’t think they would fit very well unfortunately!
Bummer as the price was so low  :(

My Scalpel has bit of a weird geometry so the the crankset needs to have specs below to work. Maybe low chance of finding a Chinese one..

* MTB Wide DUB + 3 mm offset = 55 mm chainline
* MTB Ai DUB + 6 mm offset = 55 mm chainline
