BSA English Threaded Shimano Road Bottom Bracket

They run smooth and work very well for bmx racing. Plus customer service is first class. I ordered a year and half ago and took apart my supercross bmx bike yesterday for inspection because of some noises. Come to find out the drive side cup was split. Sent a picture to bbinfinite and they shipped a replacement out next day. Will be back when my son moves to 2 piece cranks.

Working good.

Spins like a dream. I still can't get over how smooth and efficient my drivetrain is because of this bottom bracket. Highly recommended!
