  1. James –

    Super easy to deal with, very very fast shipping. Just wish all suppliers were like this. Product 11/10 OUTSTANDING !

  2. Martin Arundel –

  3. Jon P. –

    Shipping was very fast. Product arrived well packaged. The Hambini BB does not come with spacers (which I knew). A set of Chris King spacers, the SRAM frame spec, and a metric ruler were necessary beyond the BB installation tool.

    I was rebuilding my previous BB after every gravel race so I went with fully sealed (LLU) bearings. They spin decently despite being fully sealed. I’ve done three gravel races (totaling ~235 miles) and maybe another 400 road miles on the Hambini BB and it still spins like the day I installed it.

  4. Greg James –

  5. Joseph –

    Fantastic to deal with, extremely prompt with enquiries and shipping was received earlier than expected

  6. Nicholas A. –

    I needed to exchange the BB as I’d ordered the wrong one – Hambini turned around a replacement without issue. Can’t recommend them highly enough.

Q & A

Will the T47 x 68 BB clear SRAM's AXS road power meter (for 107 BCD chain rings)? It can be a tight fit, and some bottom brackets interfere. Specs can be found here, on pg. 42: https://www.sram.com/globalassets/document-hierarchy/frame-fit-specifications/road/2023-road-frame-fit-specifications-rev-c.pdf Steve Wynveen asked on December 28, 2023

I don't make any confirmation of fitting of my products, the engineering drawings are supplied and it is for the end user or bike shop to determine that.

Hello, I am looking at using this in my new gravel build. Should I use a standard or wide Sram DUB crank set? The frame builder tells me both cranks will work and the differnce in spindle length will be offset by the placement of the bearings, please adive. Thanks Frank Maresca asked on January 17, 2022

it needs to have a DBCA of at least 90mm. Hence it's usually the wide one.

Thanks for adding this item! Can I have a sleeve that is 5.5 or 6mm recess so that the hydraulic brake hose could pass through the bottom bracket area? CCJ asked on June 21, 2021

The dimensions are fixed by the standard, the sleeve section is 36mm, the outside of the bottom bracket is 47mm, so that's 5.5mm as a minimum.
