AI quick summary
- Aero gains grow with speed — the faster and flatter you ride, the more they show.
- Rim depth should match your weight, handling, and typical wind, not the pros'.
- Tire fit, external width, and warranty support matter as much as the grams.
/ 01
What 'deep section' means
'Deep section' refers to the height of the rim's wall — typically anything from about 45 mm up. A taller rim is more aerodynamic in clean air but harder to handle in crosswinds and heavier to accelerate. The depth is a trade, not a free upgrade.
/ 02
Where the aero gains actually come from
Aero benefits scale with speed cubed, so they show up most on fast, flat roads and barely at all on climbs or around town. If your riding is mostly steady 30+ km/h on open roads, deep wheels can return real watts; if it's stop-start or hilly, you'll rarely feel them.
/ 03
The crosswind trade-off
A deeper rim catches more wind, which means more side-force in gusts — and a twitchier front wheel. Lighter riders and riders new to deep wheels feel this most. A 45–50 mm rim is a stable middle ground; 60 mm+ rewards confident handlers on calm, fast days.
/ 04
Weight, stiffness, and comfort
Deep wheels are often heavier and stiffer, which can blunt acceleration and sharpen the ride quality on rough surfaces. A few hundred grams are easy to see on a scale and almost invisible on the road. Don't trade comfort and handling for depth you don't need.
/ 05
Choosing a depth for your roads
Work backward from the routes you keep riding. Sharp corners, gusts, and broken tarmac favour a shallower, stable wheel with wide-tire clearance; flat, fast, smooth roads reward depth. The best reference for any wheel choice is always the road you keep coming back to.
