Krumbachsattel

Overview

Krumbachsattel is a category 4 climb in Austria, running 6.6 km from a start elevation of 723 m to a summit at 927 m. Across that distance you gain 204 m of net elevation, giving it a moderate profile on paper: an average gradient of 3.08% places it firmly in the accessible end of the categorized-climb spectrum. It is the kind of ascent that rewards rhythm over brute force.

The headline number to watch is the gap between net gain and total ascent. While the climb only nets 204 m, the total ascent is 376 m — meaning roughly 172 m of climbing is undone by descents and dips along the way. That undulation matters: you are not paying for a single smooth grade but re-accelerating repeatedly, and the effort cost is higher than the 3.08% average suggests.

How the Gradient Unfolds

The 3.08% average is a blend, not a constant. This road rolls, so long stretches sit near flat while short sections spike well above the mean. The steepest recorded pitch hits 16.83% — a wall relative to everything around it. Expect the profile to swing between easy spinning and sudden hard efforts rather than settling into one sustained grade.

• Flatter and false-flat sections where you can recover and carry speed
• Repeated short rises separated by dips, thanks to the undulating terrain
• A single steep ramp near 16.83% that demands a gear in reserve

Pacing Notes

On a rolling climb like this, even-effort beats even-speed. Chasing a constant speed forces you to over-power the steep ramp and coast the flats, spiking your load. Instead, anchor your effort to a target sustainable power output and hold it steady: let speed rise on the flats and fall on the pitches while your effort stays flat.

Because the 16.83% ramp will briefly push you over threshold no matter what, keep a small buffer below your ceiling on the flatter kilometers. If you do not know your numbers, run the FTP estimator first so your target is grounded in real data, not guesswork.

Gearing

Your gearing should be governed by that steepest 16.83% ramp, not the gentle average. A compact (50/34) or sub-compact chainset paired with a wide-range cassette gives you the low gear to spin the wall without grinding. Aim for something in the 34×32 or 34×34 range so you can keep cadence up on the steep pitch and still have usable gears on the flats. Check your chainring and cassette setup before the ride — swapping a cassette at the roadside is not an option.

Summary

• Length: 6.6 km
• Average gradient: 3.08%
• Maximum gradient: 16.83%
• Net elevation gain: 204 m
• Total ascent: 376 m
• Category: 4

Krumbachsattel is easier than its steepest ramp implies but harder than its average suggests. Respect the undulation, gear for the wall, and pace by effort — do that and this category 4 becomes a rhythm exercise rather than a fight.
