bottom bracket threads....
« on: September 03, 2013, 07:55 PM »
is the bottom bracket thread on a one piece cranks much bigger than the thread on maxi cross cranks?

ps I don't mean the pcd....

Surely it depends on the spindle?

I've seen 2 set ups, one (generally US BB) is threaded like the BB area on a 1 piece, and then you have the euro BB spindle, with races for bearings.

Been a while though......

that's just what I though until I just tried fitting a one piece crank BB onto the threaded spindle for a 3 piece cranks.... :-\

Is it a different thread? Mongoose cranks had a different TPI on the same diameter spindle.

Or, I have a `small' us BB on a supermarket 16" mini bmx, looks like a US, but isn't!!!

Could it be either of these scenario's ?
