BEYOND THE NUMBERS

What the differences mean.

General context for the specifications where these two differ. Numbers in superscript link to the sources below each topic. How much each point matters depends on your riding, tyres and bike.

Weight: what the grams mean

The Alpinist CLX III is 174 g lighter per pair (1,131 g vs 1,305 g, manufacturer claims).

On a steady climb only total weight counts: a gram in the wheels costs the same as a gram in the frame or a bottle.1 A common rule of thumb is about 2 seconds per 100 metres of climbing for every kilogram, so 150 g works out at roughly 3 seconds on a 1,000 m climb.2

Rim weight matters somewhat more when you accelerate, because the rim spins as well as moves forward; physically that effect is at most about twice that of frame weight, and only while speeding up.1 Claimed weights are measured differently from brand to brand: some include rim tape and valves, others do not, and tolerances of around ±30 g are common.3 Independent weighing usually lands close to the claim once tape and valves are accounted for.4

Rim depth: aerodynamics, weight and crosswinds

Rim depth: 33 mm on the Alpinist CLX III, 51 mm front / 48 mm rear on the Rapide CLX III.

Cross-sections drawn to scale from the catalogue values for outer width, internal width and depth; hooked rims show the bead hook. Simplified shape, not the manufacturer's exact profile.

Deeper rims generally reduce aerodynamic drag, which pays off most at higher speeds on flat or rolling roads, but they tend to weigh more and can be more affected by gusty crosswinds. In a BikeRadar comparison, 60 mm aero wheels were about a second per kilometre faster on the flat but slower on steep climbs than a considerably lighter set.1

How a wheel behaves in crosswinds depends on the rim shape as well as its depth,3 which is why TOUR measures steering torque in the wind tunnel, not just drag.2 Shallower rims are generally easier to handle in gusts, something lighter riders and riders on exposed roads tend to notice first.1

Different rim depths front and rear

The Rapide CLX III (51 mm front / 48 mm rear) uses different rim depths front and rear.

Some wheelsets use a different rim depth front and rear, and brands disagree on the direction. Roval's Rapide CLX II paired a shallower front with a deeper rear to favour stability.1 The newer Rapide III uses a slightly deeper front than rear, and Roval argues most of the aero benefit comes from the front wheel.2 Zipp's 454 NSW rim itself varies in depth along its circumference.3

Treat a split depth as a design choice of the brand rather than an advantage in itself. If crosswinds concern you, the front rim depth is the figure to look at.

Spoke count

Spoke count front/rear: 21/24 on the Alpinist CLX III, 18/24 on the Rapide CLX III.

Fewer spokes save weight and can reduce drag slightly,1 but each spoke then carries more load and a broken spoke is more likely to leave the wheel unrideable.3 Wheels with low spoke counts usually state a maximum system weight;2 compare it with your own weight plus bike and luggage rather than judging by spoke count alone.
