Long cranks.

That’s the bike I did my PBs on minus the discs & did a 19.49 for 10miles
Me in 1986 on a cold morning outside Aberdeen.

I’ve used a 140 mm one piece crank on a klunker I once built. It had a low bb and I kept getting pedal strikes. It worked as I eliminated strikes but the cadence was very weird, choppy. I gave the bike away.
