liam-pantera Posted November 6, 2007 Report Share Posted November 6, 2007 (edited) hi im looking to buy a tpro because my ko frames has died and i was wondering will using a echo externall bb preserve the threads on the bb .last time i woned a tpro the bottom bracket threads went two times and i had to get a halfprice replacment but my understanding is that a echo bb works like a 3 peice bmx bb so would it work.
