Sella del Piccolo Roite

Overview

Sella del Piccolo Roite is a genuine hors catégorie ascent, and the numbers make the case on their own. Over 25.2 km the road lifts you from a valley floor at 221 m all the way to a summit of 2088 m — a net gain of 1867 m. That length alone puts it among the longest climbs a rider will ever attempt, and the 7.42% average gradient means there is almost nowhere to hide. The total ascent of 1843 m confirms this is a relentlessly upward road rather than a rolling profile: only a handful of metres of the climb tip back downhill across the entire 25.2 km.

How the Gradient Unfolds

The defining trait here is consistency at a punishing level. An average of 7.42% held for 25.2 km is not a wall you sprint over and forget — it is a grinding, hour-plus effort where the road keeps taking without giving much back. The spread between the 7.42% average and the 15.79% maximum tells you the ramps do bite. Expect the steepest pitches to spike toward that 15.79% figure on the harder switchbacks, then settle back toward the average on the straighter drags. Because the net gain (1867 m) and total ascent (1843 m) sit only 24 m apart, there are essentially no recovery descents built in. What goes up, stays up.

Pacing Notes

On a climb this long, discipline beats bravado. Your best tool is your FTP: pick a wattage you can genuinely sustain for well over an hour and refuse to exceed it on the early slopes, no matter how fresh you feel at 221 m. If you don't know your ceiling, the FTP estimator will get you a working number in minutes. Aim to ride the 7.42% average sections at or just below threshold, and treat the 15.79% ramps as brief over-efforts to absorb — sit, spin, and let the gradient ease rather than surging. Over 1867 m of gain, the riders who blow up are almost always the ones who spent too much too soon on the lower half.

Gearing

Do not under-gear this one. A 25.2 km climb at 7.42% with pitches to 15.79% will punish a stiff cassette long before the summit. A compact 34-tooth chainring paired with a 34×32 low is the sensible baseline for strong climbers, giving you a bail-out that keeps your cadence alive on the steeper ramps. If you are carrying any fatigue, riding at altitude near the 2088 m summit, or simply want insurance for the last few kilometres, step up to a 34×34. That extra sprocket is cheap protection against grinding to a walking-pace crawl when your legs finally fade.

Summary

Sella del Piccolo Roite is a long, honest, unforgiving HC climb: 25.2 km of sustained work at 7.42%, with no meaningful descents to break the rhythm. Pace it by your threshold, gear low, and respect the full 1867 m of vertical between the base and the sky.
