Campagnolo Record Double Bottom Bracket

This is a bottom bracket with an oversize hollow axle, truncated taper, carbon fiber spacer joint and an oversized axle pin that is suitable for double cranksets.
It has a composite/light alloy cartridge and as a result is very lightweight, yet extraordinary rigidity and interfaces perfectly with the crankset to convert the rider's energy into motion with maximum efficiency.
Weight only 190g.
