Title: Crank - it's not the bloody same !
Post by: BENDYCAT ELEVENTEEN on November 28, 2012, 11:13 PM: Looking at a Mongoose stamped crank and there seem to be more TPI (Threads per inch) than the standard crank ? can any one confirm this ???

and does any one have a spare locking nut (the hex looking one) for a mongoose crank :angel:

cheers B ;)

On US eBay you can get a Schwinn 28ti BB for $13 but then it needs postage.

Post by: threaders on November 29, 2012, 09:33 AM: I had the same trouble last year untill I found out they were 28tpi. I put an ad in the wanted section for a 28tpi bb and got one from there :daumenhoch:

Post by: Waxintaxin on November 29, 2012, 10:05 PM: They fit 401s so they are rarer than the 24tpi
