Want to make your bike faster than any other? Had enough of servicing your ceramic bearings so that they will survive another rainy day race? Would you rather have a bottom bracket outlast your frameset? Then you have arrived at the solution. XD-15 ceramic bearings have it all - hands down the speediest, and longest lasting ceramic bearing available on the market. Nitrogen steel is the secret, precision machined and ground to ABEC-5 tolerances at our facility in Gilroy, California. Voted “Hands down the best bottom bracket we have ever tested” from Bike Radar, you can find out why. These bearings spin with the very least resistance of anything we have developed to date featuring oversized Grade 3 Silicon Nitride balls. On top of this, they will be spinning with the same ease one year or even two years from now, with longer intervals between servicing. No one else in the bicycle industry offers this combination of speed and durability: XD-15 bearings for wheels, bottom brackets, and drive train.
- XD-15 are Corrosion Free, little serving required!
- Si3N4 Grade 3 Balls
- Silicone Seals allow Faster spinning
- New Limited Warranty
- Enduro LLB Type Seals
Our most popular seal type, this is a Nitrile material rubber with a steel insert. Rather than the standard 2RS type seal, we go a step further by machining a groove into the inner race where the seal can rotate with better efficiency and less rolling resistance. Rather than one thick seal lip rubbing on a blunt surface, LLB type utilizes two razor thin sealing lips riding in the groove with light contact. The outside lip keeps the water and contaminates out, while the inner seal retains the grease for smooth function and long intervals between servicing.$188.85 (RRP)Add To Cart

* Picture not actual kit
Pivot bearings are exposed to a vast range of dirt, water, sand and other abuses. We have designed our MAX type bearings to handle these extreme conditions and use them in all of our suspension kits. They have a 35-40% higher load capacity than the standard retainer type bearings most people sell. We also pack them on both sides with a high impact, water proof grease.
The result for you is a much more active and quick rear suspension, eliminating play and wag all at the same time. Upgrading your rear suspension with Enduro Bearings MAX bearings will save you time and money, as they will perform well 2 or 3 times longer than the stock set up.$81.61 (RRP)Add To Cart

Proven time and again in World Cup race conditions, the ZERØ Ceramic bearings are the ultimate race day weapon. Oversized Grade 3 balls roll on races which are ground to a mirror finish after receiving Magnetite and then Cryogenic treatments for hardness and longevity. More durable and with even lower rolling resistance than any 2RS bearings, they come closer to that magic “zero” rolling resistance number. Enduro Bearings uses Silicone seals which are more slippery than rubber seals used by other ceramic bearing suppliers. We get more email and blog feedback on the ZERØ's than any other bearing, describing the noticed difference in downhill rolling speed. And they win the independent wattage output tests when stacked against the competition. If you want to buy raw speed, ZERØ bearings are it.

- Grade 5 Chromium Steel Balls
- High precision balls are within 5/1,000,000? round. These are military level specification, used for precision equipment. R-64 hardness, of the highest grade.
- 52100 High Carbon Chromium Alloy Races
- Vacuum de-gassing process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-5 precision and noiseless movement.
- Graphite/Nylon Ball Retainers
- Nylon with graphite retainers are virtually frictionless while providing constant lubrication.
The ABEC 5 Standard
To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.
C-3 Clearance
This specification describes the internal clearance between the bearing and its race. For example, in a 10-18 I.D. bearing, our standard is 11-21 micrometers where as others use 11-25 micrometers.
