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?

    Don’t listen to the professional haters or B$ of the over priced vapourware marketing gainz.

    Hambini provided me with a super fast response over email on how to get hubs reamed and improve bearing fit prior to making a purchase.

    The advise and new bearings have brought about not only a silky smooth ride, but also competitive times in TTs.

    And prices are superb! will be purchasing more Hambini supplied bearings in future.
