• Enduro XD-15 ceramic ball bearings are made from pure silicone nitride material with extreme high density and uniform compaction
• The race material is an advanced stainless alloy that is nitrogen infused and will not rust or corrode
• Dual stage anodize black and gold machined aluminum bottom bracket cups
• Kluber NBU52 grease runs better and smoother with time, and is highly resistant to being washed out
