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?

  1. Nik James

    I used these as replacements for the stock bearings on my cannondale, the stock ones lasted 300 miles before the creaking got too much for me. The difference between the NTN and the FSA are like chalk and cheese. The NTN one feels super smooth and does not creak. 600 miles on the bike and I’d forgotten about my previous woes.

  2. James Betts

    I swapped the original bearings on my classic hambini BB after 8000miles for these ones. The originals were very good and didn’t give problems, these are like butter. So smooth. Spins forever.

  3. Slick50

    Best bearings by a mile. None of that cycling boutique bollocks. These bearings are super smooth, fit well and creaking goes away. A fraction of the price of ceramicspeed and they last well.

  4. Rob Timmins

    Great bearings and you can feel the difference. Not sure they are worth the expense of the non super precision.

    Fast service, no friction, no bullshit, and cursing. What’s not to like?
