Road cycling wheels: shallow, mid or deep section?

Cyclists know that road cycling wheels are an important asset as they are your main contact with the ground. Your cycle wheels support your body weight and are important in determining the quality of ride.

The rims on your cycle wheels are an important factor in determining quality of ride and are usually shallow section, mid section or deep section, ranging from 25mm to more than 40mm in depth.

Shallow section wheels can be very durable and usually provide a comfortable ride experience. These wheels can be used for any kind of riding and prices range from entry level to more expensive top of the range models.

Mid section wheels are not so popular but they do have a lightweight rim and modern developments in cycle wheels mean they can be ideal for general use, being light enough to use for climbing and fast enough for the open, flat roads.

Deep section wheels provide the highest speeds when flat road riding. They are great for sprinting but are also light enough for mountain riding, when necessary.

When you purchase an entry level cycle it’s likely that shallow section wheels will be fitted as standard.

Road cycling rims: why are they so important?

The cyclist’s choice of road cycling rims is a choice that will support his for her ascent to the championship or descent towards road rash. This is a choice that has safety, performance, and more subtle technical qualities at play that affect comfort and joy in cycling. Rims are a large factor in how long the wheel lasts on the road, and its resiliency when faced with the cyclist’s weight, and momentum against a sudden need to stop.

One of the bicycle rim’s major functions is to ensure proper handling despite the dangerous implications of the laws of physics. Cycling should be about enjoying movement, and the tires should certainly be in no position to detract from that. For this reason, consumers are likely to notice that rims are starting to come out with wider bases to better combat turbulence and allow for maximum speed with minimal instability.

Another development in the cycling industry that can impact a cyclist’s decision in rim is whether or not to go tubeless. Tubeless tires are becoming all the rage these days, making the bicycle rim industry have to adapt new compatible rims. Tubeless tires do, by several accounts, help improve speed. The consumer is, however, left with a little bit of a heavier rim to fit with the tubeless tires, though this potential downside is minimizing as advancements are made in the industry.
