Sometimes it is what you can't see that matters. In this case it is what Campagnolo calls UHS or Ultra-Hollow Structure. This refers to the hollowed out crank arms and spider. Think about that for a moment. Not only did Campy figure out a way to leave a hollow channel in the crank arm, they also carved out all of the carbon in the spider as well. Stout and burly on the outside and completely void of anything but air on the inside. This is not new, but we though it is worth a mention. What is new are the totally re-designed chainrings and how they attach to the crankset.
Campagnolo engineers have developed the XPSS style chainring which offers 8 ascending zones for up shifts and 2 descending zones for down shifting. Coupled with the AFT anti friction coating, the shifting has never been faster and more accurate. These zones along with the slippery AFT coating literally escort the chain back and forth from inner to outer ring and back. Gone are the use of chain ring bolts. Now we see just one bolt that is inserted through the hole of the outer ring/spider and threads directly into the inner ring. This reduces a small amount of weight, but more importantly, increases strength and rigidity.
Updated contrasted white graphics match the rest of the Record group and make the cranks pop. High quality bearings are installed on the axles, but the BB cups must be purchases separately.
