Basic but good enough
Straightforward bottom bracket at a great price, easy to fit and doing its job.

After 3000 kilometres it's still in good working order. From my experiance the external cup bottom brackets always outlast internal bearings. I much prefer the the Hollow Tech ii over the octalink I had previously. It seems much stiffer.

I am replacing a bottom bracket marked "BC1.37 x 24 ROAD". Chainrings are Shimano FC-4550-S 50 teeth and Shimano Tiagra FC4550 34 teeth. Is this bottom bracket a suitable replacement as "BC1.37 x 24 ROAD" does not appear to still be available.
Is this compatible with tiagra a fc 4600 groupset and a fc 4650 tagra crankset, reason for asking about both is i have a 2013 caad8 tiagra and im bidding on a fc 4650 crankset. The caad8 uses a fc 4600 groupset.
