Chainring Campagnolo XPSS 5-bolt 50T 11-speed (110 BCD)

The Campagnolo XPSS 5-bolt 50-tooth 11-speed chainring (110 BCD) is designed for 2011–2014 Campagnolo 11-speed compact cranksets (such as Super Record, Record, Chorus, and Athena)

Key Specifications & Features

• Tooth Count: 50T (commonly paired with a 34T inner ring) 

• Speed: 11-speed Campagnolo shifting systems (not compatible with 12-speed or hydraulic-group specific changes) 

• BCD & Bolt Pattern: 110 mm BCD with a 5-arm mount, featuring Campagnolo's proprietary hidden bolt placement (where one bolt threads into the back of the crank arm). Standard non-Campagnolo 110 BCD rings do not fit due to this layout. 

• X.P.S.S.™ Technology: Features specialized shifting pins (4 pins for the 50/34T configuration) and flat-machined alloy construction for smooth, precise chain pickup and shifting performance
