Hey all:

This one is a puzzler to me.

I recently bought a Raleigh Competition with a Spidel crankset. due to weather I haven’t ridden it more than a quick “tryout “.

I’ve been working to get it up to snuff and just realized that the left crank arm doesn’t match. It’s a cosmetically similar (but 5mm shorter) Japanese crank arm, maybe an SR.

of course I need to rectify this. There’s a Spidel crank arm on the ‘Bay right now that’s listed as “French threaded”. Does this refer only to the threading for the pedals? Would I be able to fit this on the existing bottom bracket?

I’m kind of a newbie when it comes to wrenching on this stuff. What do I need to know/look for when seeking a replacement?

thanks!
