What our customers are saying about Bonin BSA bottom bracket

This economical square taper bottom bracket offers excellent value. It features a full aluminum body and metal housing, providing good quality construction and smooth-spinning performance. Praised as an easy-to-install replacement part, it is available in a hard-to-find ITA 70mm version. While long-term durability is unconfirmed, it´s a solid choice for the price, though one user noted a crank screw loosening

Moreno

I bought this bottom bracket and the Prowheel Shimano triple crankset at the same time but the coupling seems not to be suitable, it remains to be seen if the taper is the same for both considering that the locking screw tends to loosen even with the use of thread lock. The bottom bracket has a good quality-price ratio.

Product conforms to the description

Hugues

Product conforms to the description, neat packaging, despite a small price. It seems to be running smoothly, more than to try it to check how long it will last.

Amigo includes the bolts that hold the steering wheel and at the same time also the threaded bucket, it comes complete!

Hello, will this case be able to replace a Kenli case in 73mm and 127mm length? The description is not very competent!!

Answer of ADRIAN

Hello, if you choose the 127.5mm long option, it is valid for you. Then the width of the case in its middle part is 68mm and in the thread where it anchors to the frame it is 73mm so if your old one has those measurements it should be valid for you.

Answer of JOSE

Hello, it is 127.5 x 68mm in its middle part and in the thread where it anchors to the frame it is 73mm.
