Cotter Pin Crank conversion?

Recently I had the joy of being clipped by a taxi and my bike taking most of the damage.

My pedal snapped out of my crank arm taking the threads with it.
I have a cotter pin crank but its been a pain to find a low cost replacement component however I have found numerous crank sets on here that I would install instead. Is there a way of converting the crank without replacing the BB completely?

There are square tapper axles for sale. I've considered this option for a minute but bought cartridge BB in the end. It's easier and cheaper.

I have 2 cotter pin style bbs and 1 cotter pin crankset I have no intention of using. Kat something from on here took 2 halfs(a drive and a non drive side from one and the other) as the other 2 are rather stuck. If you have the tools+time to get them out then they are yours. I'm only planning to use one of the frames which is currently half way sanded for painting. Have said once I take time to get the other crank arms off will pass them to Kat but I'm sure she won't mind you having the other if she has a set still.

Yeah that would be great thanks! Would it be extremely difficult to get them out?

The BBs look ok(no signs of rust or anything) so I can't see a reason for them to be overly stuck. The crank arms one of them the pin is loose but need to get around to getting a punch to get it down past the edge of the crank arm, the other one the pin is out but it's just really stuck on but maybe there is some trick to removing them I don't know.

I'm in streatham hill SW2, send a pm or something and it shouldn't be hard to work something out.

No: the interfaces between the cranks and BB (ie "square taper" or "cottered") aren't interchangeable.

However, square taper cranks and BB are cheap, plentiful and a useful upgrade over cottered ones.

Just remember to match the front and rear chainlines.

PM'd

Thanks guys!

No need for a PM, bit pushy, and a problem resolved in public is available for future reference and the benefit of all.

Was a pm to take up on the offer of free cranks/BBs.

Mine wasn't.
