Excellent product, after sales and support even before I bought it. It’s so much easier when you can talk to the guy that made it and not someone who doesn’t give a rat’s ass in CS. I got the local bike shop to install it and wasted $50 doing so. I could have done this myself it’s tooo easy. On the bike and it’s a dream. The internal sleeve does a job to line everything up. Put the crank in and away you go. Extremely well made, this is not a bike part, it’s a work of art. My mechanic said this was the best bottom bracket he had ever seen.

Installed on my custom T47 frame. I have not had any issues. Very well engineered and the customer service is excellent. It might seem expensive but you will not regret it.

Fantastic. Went straight in to my Enigma frame and paired it up with DA, it spins like crazy. The rigid center sleeve was a genius idea. I see this has come over from the BSA. I would buy another without a thought. Great Job Hambini

Perfect in every way. So well made. Info for others, I used a Park Tool BBT47 and it fitted like a glove for installation.

Beautiful looking product and great quality – Hambini very helpful in dealing with queries and responded promptly. Little pricey?!

This BB is a work of art and science, top of the line no BS engineering from a highly qualified Engineer. Hambini answered all my questions promptly and has been super helpful before, during, and after the purchase. A true professional/expert and gentleman. We need more professionals like Hambini to tell us the truth as it is, help us understand the True Science/Data/Research findings behind the engineering/quality of each product so we can make well-informed purchase decisions based on the Truth, NOT Marketing Gibberish/Captivating Commercials from the big players on Youtube or GCN’s highly sponsored/biased videos. What a pleasure it’s been riding my Litespeed with this BB, much more smooth, quiet and transfers power much more efficiently than the Chris King T-47 on the stock bike.
