When it comes to building or upgrading a wheelset, spoke count is a key factor often overlooked by casual riders. While rim choice and hub engagement matter, the number of spoke holes in your hub has a direct impact on strength, weight, and performance.
For road cyclists aiming to strike the perfect balance, selecting between a 20 hole rear hub, a 20h disc hub, or a 24 hole rear hub requires an understanding of riding style, terrain, and wheel design.
The spoke count refers to the number of spoke holes in a hub (and rim), which determines how many spokes can be laced into the wheel. Road hubs typically range from 16 to 36 holes, but 20h and 24h configurations are among the most common for modern lightweight performance builds.
Lower spoke counts reduce overall weight and aerodynamic drag, while higher spoke counts provide additional strength and stiffness—especially important for heavier riders or rougher roads.
A 20 hole rear hub is typically used in high-performance wheelsets where weight savings and minimal wind resistance are the priority. These hubs are ideal for:
However, the reduced spoke count does sacrifice some lateral and vertical stiffness. Riders over 75kg or those regularly riding on uneven roads may find 20h rear wheels less durable over time.
The 20h disc hub is a specialized option, usually chosen for disc brake bikes that prioritize lightness without sacrificing stopping power. These hubs are relatively uncommon but serve a niche purpose:
Because disc brakes place asymmetric forces on the rear wheel, 20h disc builds must be carefully tensioned to maintain strength. They are best suited for lighter riders or race-day use.
A 24 hole rear hub is widely considered the sweet spot for many road cyclists. It offers a solid compromise between weight and structural integrity. Benefits include:
For most riders, especially those who value versatility and everyday reliability, the 24h rear hub is an ideal choice. It handles a broader range of rider weights and riding conditions while still keeping weight reasonably low.
| Hub Type | Best For | Considerations |
|---|---|---|
| 20 Hole Rear Hub | Weight-focused road setups | Less stiffness, not ideal for heavier riders |
| 20H Disc Hub | Lightweight disc brake builds | Niche option, tension-sensitive |
| 24 Hole Rear Hub | All-around road use with a balance of features | Slightly heavier, but more robust |
Your rear hub’s spoke count is more than just a number—it directly impacts how your wheels perform under stress, accelerate, and withstand long-term wear. For featherweight builds or race-day wheels, a 20 hole rear hub or 20h disc hub can offer a competitive edge.
But for most road cyclists looking for durability without sacrificing speed, the 24 hole rear hub is the go-to choice.
Make your decision based on your riding goals, body weight, and road conditions—and you’ll enjoy the right balance of speed, strength, and performance.
