Designed and manufactured in France by Stronglight. Carefully crafted using the finest materials. The STRONGLIGHT CT2 Campagnolo Ultra Torque inner chainring is a high-performance road plateau. Both robust and precise, made of high-precision machined 7075 T6 aluminum and CT² technology, consisting of a ceramic coating with a layer of Teflon. The addition of ceramic allows for better hardness, increased durability and an anti-abrasion effect. The addition of teflon reduces chafing of the chain, thereby reducing noise and friction, and optimizes indexing between plates. Combining strength, lightness, precision, efficiency and ease of use, this CT2 chainring is here intended for Campagnolo Ultra Torque cranksets with 112 mm centre spacing (BCD). Colour: black. Material: CT2 Aluminum
