The Campagnolo 11-speed cassette in 12-29 provides a very usable gearing range with the 29 allowing an easy ascent up virtually any incline. The largest three cogs are made from Titanium for the most weight savings while the smallest 8 are made from nickel-chromed steel for longevity. It is only a few grams heavier than the Super Record but should last a tad longer.
Ultra Shift® profiles cogs give excellent shifting and work hand in hand with Campagnolo's 11-speed Ergo levers to provide smooth, lightning fast shifts with almost effortless rider input. The largest first two sets of 3 cogs are mounted to a lightweight alloy carrier frame for strength and weight savings while the smallest five cogs are loose.
