A compact chainring setup (50/34) with an 11-30 or 11-34 cassette is ideal for most riders on a climbing bike. Stronger riders may prefer semi-compact (52/36) with an 11-28 or 11-30. The key is having a bailout gear for the steepest climbs — a 34×34 ratio gives you a 1:1 gear that can spin up almost anything. Do not gear yourself too hard to look pro — proper gearing lets you maintain cadence and power on steep gradients.
