Product Description

Not to let the roadies have all the go-fast goodies, Enduro offers their latest high-tech bottom bracket for the off-road set as well. The XD-15 Ceramic MTB Bottom Bracket is set to change the way we think about bottom brackets. It's combination of smoothness, reduced drag, and durability make it perfect for the mountain biker looking for every advantage to go faster down the trail. Even though it looks similar on the outside, it's different than any other external bearing bottom bracket currently on the market. The truth is that the XD-15 is different than other bottom brackets at its very heart -- the bearings. Where every comparable bottom bracket assembly relies on radial contact cartridge bearings, the XD-15 uses an angular contact design. It's almost a throwback to the days of square taper spindles, before cartridge type bottom brackets. If you remember that far back, bottom bracket bearings were of an angular contact design. This allowed the most particular mechanics to fine tune the preload on the bearing set to that point of perfection between zero drag and the tiniest hint of play. And here's a secret that shouldn't be one -- the loads on a bottom bracket were the same then as they are now, except for the fact that installation of the cranks didn't load the bearings back then. And sure, moving the bearings and increasing spindle diameters changes things a bit, but the basic radial and axial components are still there when we pedal or stand on the cranks. The current problem with standard sealed cartridge bottom bracket bearings is that they're not designed to bear much axial loading, if any at all. At the same time, most crank manufacturer's designs rely on axial loading as part of their recommended crank installation. Enduro has found this to be one of the culprits that leads to premature bearing wear. And the XD-15 eliminates this singular weakness of typical, modern external bearing bottom brackets.The XD-15 is optimized from the outside in. Look at the cups. You'll see that they've machined away excess material on the outer diameter, actually removing every other tool notch. Careful installation will get it in place and torqued to spec, and the saving of a few more grams helps the XD-15 tickle the scales compared to the best from Shimano, FSA, and SRAM. Inside these featherweight cups is where the real action is. Enduro presses in ultra-hard and corrosion resistant nitrogen infused steel races for the Grade 3 Cerebec ceramic ball bearings to roll on. These high tech bearings are round to 3 millionths of an inch. The 3/16

Strengths:    Increased climbing performance. Super smooth. Increased my ability to overcome technical inclines and scale drop offs.

Weaknesses:    None that I am aware of

Bottom Line:   
I recently replaced my SRAM GXP BB that came with my crankset. After about A month I started getting a lot of creaking and squeaks especially when climbing. I decided to try the XD-15. I noticed a significant improvement in power to the cranks. I'd say 20-25% increase in climbing ability. I usually take 3 breaks on a trail that has a long steady incline. Now I only need one break and am extending how far and how fast I ride. The smoothness and power transfer were really a positive surprise. I also noticed a significant amount of power when taking on technical challenges. I think this was one hell of an upgrade.

Bottom Line:   
Been running this for a year after dealing with replacing my SRAM GXP BB every 6 months. No drag on this at all, spins forever. Easy to work on and a quality part.
I had an issue with the interface of the spindle offset of the SRAM spindle and the BB but Enduro answered me request for help in short arder and had me back on the trail.
Great product and excellent customer service.
