broke L345 Posted October 24, 2017 Author Share Posted October 24, 2017 Sorry for not responding Patrick They are 25mm, I have found the bearings, now I believe I need to find Redline Techmatic BB cups to suit the outer diameter. I guess I need a new search. The outer diameter of the bearings is 47mm Quote Link to comment Share on other sites More sharing options...

supercross Posted December 16, 2017 Share Posted December 16, 2017 Hey Broke L345, I was going thru the storage today and found a bin of some of the old Strong Arm Crank Cups and some bearings, They are NOS from 96' or so, so about 21 years old. E-mail me if you need them and we can work something out. And it is a 25.4mm 1" spindle on our old Strong Arms, it is part of what made them so stiff and allowed us to run Aluminum Spindles back in the 90's. Hope you all have a great day!
