I thought I'd share some pictures and first impressions of these cranks. I haven't ridden them yet, I'll share my experience with them later. If others have experience with these cranks, please feel to share them.

I just bought and assembled the Fovno Thunder 216 RC-216 24mm axle cranks in 170mm, with a Fovno RL-228 spider for 2x 110 BCD chainrings, to replace my old Sram S350 175mm cranks. I wanted shorter cranks for my 11 year old road bike, without splurging. Seems like good quality for the price.

Some specs:
- Axle: 24mm, aluminium
- Chainline: 44.5mm
- Q-factor: 146mm
So far so good, it was easy to assemble. I went with a Shimano BB86 SM-BB71-41B BB, as I wanted to avoid steel bearings in direct contact with the aluminium axle.
