When it comes to adventurous riding, a wider gear range is often better. With 9 speed and a 11-42T range, the ADVENT cassette has the low gears you need to get up and the high gears to get back down. The steps between gears are optimized to give an even spread in gear ratios, reducing the need for double-shifting to find the right gear.
