This is a recently purchased 103mm square taper bottom bracket with 103mm axls and 68mm blue anodized alloy cups for Enlish threads, sealed bearings. The body is engraved.( I think- as very difficult to read small lettering) "SHONGU◇ZY FOR 68MM - L-R -ZXZY BIKETAOBOA.COM " and a product serial number "2501054" It's a well made UN-72 clone wis steel axle and smooth bearings. It was purchased new online in April 2026 to replace a worn unit but was is too narrow. I later used a 110mm unit for clearance and this is now surplus. It has some grease from fitment but zero miles. The surfaces and threads are pristine.
