Campagnolo Record UT 39/52 Crankset

One of Campagnolo's top tier groups. A Group Set made from excellent materials with an approachable price to match. This group weighs less than the Chorus Group Set but is not as light as the Super Record. The three groups share the same technology for their mechanical parts but the materials they are made from vary resulting in the different weights and price ranges. The 2014 Record Group Set tries to emulate the previous Super Record generation. The updated ergonomic design of the shifters has made them more comfortable. Campagnolo produces these shifters from new materials that make them lighter without sacrificing strength. The new design allows for a light shift and a more positive feedback from the sound of shifting. The XPSS (eXtreme Performance Shifting System) chainrings also improve the the shifting experience.
