Q. What is the best bearing brand?

NTN, NSK, FAG and SKF are all quality bearing suppliers and their products meet ISO/JIS/DIN standards. When selecting a bearing it is important to ensure that the bearing fits correctly within the enclosure. Far eastern bearings sold on ebay or amazon are often out of specification in one or multiple parameters, these fit issues manifest themselves as creak or poor bearing life. Some sellers have been known to sell fake bearings which are very difficult to spot without specialized measuring equipment, fitting these usually presents the same problems. In short, fitting genuine branded bearings is recommended

Q. Which seals do you recommend?

For road racing, NTN LLB series, SKF RZ series and NSK VV series are recommended. For inclement weather or extended life, NTN LLU series, SKF 2RS series, NSK DD series or FAG 2RS series are recommended

Q. Which bearings have the lowest friction?

NTN LLB series followed by NSK VV series, SKF RZ series and then FAG BRS series

Q. How many bearings is this listing for?

    Just spares for the long run – the ones already installed in the BB beat the Shimano Dura Ace BB86 composit shells by lengths

    I tried a few other online UK sellers before I got these ones. I would come here again, they are expensive but you are buying real bearings and not the defective ones

    I wish I had bought from here originally. Hambini is a bit more expensive but you are getting genuine bearings. Some of the other online retailers are blatantly selling fakes and ntn don’t seem to care about it.

    Service and technical support are as to be expected, the lick

    Fast shipping. There has been a mix up in the bearing type but Hambini immediately offered a discount! Top notch!
