Enduro 2437 24x37x7 XD15 G3 BB90
Direct OEM replacement for most BB86/92, Trek BB90/95
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.

Enduro Bearings manufactures some series of bearings using 440C stainless steel balls and races. This material provides maximum corrosion resistance in applications and environments where critical. Depending on the application, they are designed to ABEC-3 or ABEC-5 tolerances. Stainless steel has 20% less load capacity than the 52100 chromium steel, used in most of our bearings, but with far superior corrosion resistance.
When the rain won’t go away, and your bicycle is more often used as a boat rather than a land craft, you may want to consider 440C stainless steel bearings. While a little softer than chromium bearing steel, 440C stainless steel is a good alternative in constant wet conditions, or where sweat becomes a problem such as headset bearings. Enduro Bearings uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements.Stock Level:In StockStock Level:In Stock$73.46 (RRP)

- 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.
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.

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.

Enduro VV Type Seals
Developed with the idea of rolling as fast as possible, this dual lip configuration does not make contact with the bottom of the machined groove. Since these bearings also have a high rate of grease fill, the grease migrates to the bottom of the groove where a hydromatic type seal is established between the 2 lips and the grease in the groove. This grease barrier keeps the dirt and contaminates from coming inside the bearing, while still rolling smoothly and with the least resistance of all our bearings.Stock Level:In StockStock Level:In Stock$96.89 (RRP)
