De Beer's Pass

De Beer's Pass cycling climb profile

De Beer's Pass is a climb that rewards restraint more than aggression. On paper, it is 6.2 km long at an average gradient of 3.45%, gaining 215 m from a start elevation of 1,469 m to a summit elevation of 1,684 m. That puts it firmly in Category 4 territory: enough climbing to matter, but not steep enough to force the race or ride open on gradient alone.

The key number is the maximum gradient of 5.71%. That tells you the climb is not defined by a wall or a sustained double-digit section. Instead, the difficulty comes from holding pressure over a moderate ramp while avoiding the common mistake on climbs like this: riding it as if the average gradient makes it free.

How the gradient rides

With an average of 3.45% across 6.2 km, De Beer's Pass should feel more like a long drag than a pure mountain ascent. The road rises steadily enough that aerodynamics and momentum still matter, but the elevation gain is meaningful enough that repeated surges will accumulate quickly.

The gap between the average gradient and the 5.71% maximum suggests the harder moments are controlled rather than decisive. That matters tactically. A short steepening near that maximum is not likely to force a huge gear change if you have paced correctly, but it will expose riders who have been sitting too close to threshold from the lower slopes.

Pacing and gearing

The smart ride is to start below your target climbing effort and let the climb come to you. Because the gradient is moderate, speed can stay relatively high compared with steeper climbs, so pushing a bigger gear early can feel efficient while quietly lifting the cost. If you are riding by power, settle into a sustainable range linked to your FTP, then only lift the effort once you are confident the summit is within reach.

Gearing should be chosen for smoothness rather than survival. You do not need to prepare for an extreme ramp based on the listed maximum gradient, but you do need enough range to stay seated and controlled when the road approaches its steepest point. Spinning slightly easier through those changes is better than grinding and turning a manageable Category 4 climb into a muscular effort.

What matters most

De Beer's Pass is not about one decisive pitch. It is about resisting the false comfort of a 3.45% average gradient over 6.2 km. Ride it with a steady tempo, protect momentum, and avoid unnecessary accelerations. Done well, it is a controlled aerobic climb. Done badly, it becomes a slow bleed from overconfidence at the bottom.
