    Silkier than a silk worms under crackers !

  2. Joseph

    Finally, no more creaking BB! Lesson learned? Just say “no” to cheapo bearings. Shipping to USA was quick.

    Bearings run smoothly, huge improvement over Enduro bearings fitted by LBS, easy to fit with correct bearing press, and good instructions on YouTube by Hambini.

  19. Philip W.

    The bearings were excellent quality. I had 2 questions and both were answered within 24 hours – excellent service.

  20. Riley H.

  22. Adam Taylor

    Arrived very quickly. The difference in drag from my old bb is ridiculous

  23. Paul Webb

    Great service and fast delivery. A quality set of bearings that were easy to fit with a bearing press, my bike’s bottom bracket now feels amazingly smooth. Thank you Hambini

  26. Ian B.

    No frills quality item

  27. Kester Hewett

    My ocd precision engineer father-in-law was impressed by the quality (he makes fishing reels) but sceptical about your price. His go to bearing supplier couldn’t do this spec, other than Enduro – so I feel vindicated 🙂

  28. Zuhir Khan

    Super smooth, Hambini always delivers with premium parts! Highly recommend. Customer service is 10/10!

  29. Graham J.

    Bought to replace worn out BB bearings. Easy replacement in the Hambini BB and very smooth and friction free so far.

  30. Jeffrey B.

  31. Ian Claridge

    No fuss no bother and prompt delivery of a quality product

  32. Philip W.

  33. Patrick McKnight

    NSKs delivered. Original FSAs lasted about 1500km. Ceramic Wheels Mfg lasted about 4000km. Looking forward to see how a quality bearing performs.

    Thanks Hambini for fair and honest distribution of high quality bearings!

  34. Anonymous

    Despite being shipped internationally, got to me faster than domestic orders. Very happy. Great experience.

  35. Patrick M.

    Great purchasing experience. I had a few technical questions after the installation of my new bearings. Response was prompt and insightful for my situation. Highly recommended!

  36. Richard Howl

  37. Iain Arthurton

    great q

  38. Christopher

    Easy purchase process. Quick shipping.

  39. Paul W.

    Great service as always from Hambini. He spent a considerable amount of time and effort helping me with an issue I was experiencing with my BB. I ended up ordering new bearings which arrived promptly. He could have suggested spending more on a new BB but he didn’t. He really wants the customer to get the best option without spending for the sake of it.
    If I could give 6 stars for customer service I would.

  41. Martin F.

    I have purchased these as a replacement for the existing bearings which I intend to replace during the winter, so I have no experience yet of their performance, but they seem very well made

  42. N A Hutchinson

    Good gear !

  43. Daniel

  44. Maria Lashley

  49. David N.

    Excellent customer service. Fast delivery to ROI post Brexit. Responsive and helpful on email. Recommended.

  50. Dominic Britt

    Excellent quality sourced bearings. Direct response and fantastic advice from Hambini himself on how best to fit them. Can’t fault the quality of goods and service – highly recommended.
    Will be looking at bearing bracket kits in the future.

  51. Hung Ngo

  52. John C.

    Arrived rapidly, super quality bearings. I followed Hambini’s video on BB30 repair and the job was done in 15 mins. My BB is now now quiet and smooth. I am an absolutely happy customer. Thanks.

  53. Nick

    Excellent service, 100% recommend!

  54. Paul M.

    Contacted Hambini to find out my options for replacing the bearings in my Hambini BB settled on these and I’m not disappointed good quality and super smooth
    Brilliant service with prompt postage

  55. Anthony Turner

    The postage requires a signature which is not possible when working away from home. The bearings then end up back at the PO sorting office which is only open weekdays 0800-1000 requiring time off work to collect. Is it possible to post the bearings so they can be delivered through the letterbox?

    • admin

      Thanks for your comment, as the item is postage tracked and fully insured, it requires a signature upon delivery.

  56. Iain

    Spot on

  57. Lukas

    The NTN bearings that I received fit well and run smoothly.

  58. jose

    Definitely better then what came with the bike delivery was quick, had a question hambini responded same day, in his usual fashion, answered my question in detail what else can say, keep doing what your doing Hambini

  59. Craig F.

    They’re bearings, they spin.

  60. Darryl K.

    Got NTN. No BS. It took about 2 weeks in snail mail to Toronto during all time bike part shortages.

  64. Richard Beasley

    Super quick delivery, efficient ordering, quality bearings and without doubt a supplier of the highest standards. These bearings spin so much smoother than the usual stuff you’ll get from your LBS.
