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 Aero CS 50 is 45 g lighter per pair (1,237 g vs 1,282 g, manufacturer claims).

Aero CS 501,237 g

Aero WT S 501,282 g

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

Carbon or steel spokes

The Aero CS 50 uses carbon spokes, the Aero WT S 50 steel spokes (16/20 vs 24/24 front/rear).

Close-up of the aerycs Aero CS 50 hub and spokes — **Aero CS 50** 16 front / 20 rear · carbon

Close-up of the aerycs Aero WT S 50 hub and spokes — **Aero WT S 50** 24 front / 24 rear · steel

A carbon spoke weighs roughly half as much as a premium steel bladed spoke,¹ and brands state that carbon is stiffer for its weight.² That is why carbon-spoke versions often use fewer spokes and weigh less: Hunt's Limitless Ti_UD uses 15/18 carbon spokes against 20/24 steel spokes on the standard Limitless.³ Some reviewers describe a more direct feel when sprinting; that is a riding impression, not a measurement.⁵

Steel spokes such as DT Swiss Aerolite or Sapim CX-Ray are standard parts that most workshops can source and replace.⁴ Carbon spokes are more sensitive to side impacts, for example from a derailleur or debris, and may need brand-specific parts or tools;¹ some brands include spare spokes or crash replacement to offset this.⁵ Visually, the lower spoke count and slim blades give carbon-spoke wheels a lighter, more open look.
