Are Wider Road Bike Rims Better

The claims are lower rolling resistance better aerodynamics a more comfortable ride and better handling.

Are wider road bike rims better.

Wider rims are faster and they save you power that is they re more efficient particularly on rough roads. The ride quality is better. The width of the rim can impact the width of the tyre. A 25mm tyre fitted to a wide rim can actually measure 27mm across and it s a trick that some manufacturer have recently employed with their latest endurance bikes.

What width tyres should i choose. That depends on the width of your current tyres and if your frame and rim will accept wider tyres. While the area of the tire patch for both tires is the same as long as your weight and the tire pressure is the same that area spreads further across the width and less along the length of a wider tire. Most are the result of the increased air volume due to the wider base.

The limitation now is. The wider tire provides a wider contact patch than on a narrower tire. While the burgeoning dirt gravel and adventure riding segments have certainly directed newfound attention to road tire and rim widths the wider is better movement started well before heading. Wider widths have helped transform the feel of a wheel over the last few years.

A typical 23 mm tire tube on a 19 mm rim holds about 720 000 cubic mm of air. Moreover wider rims are better on descents.
