Are deep rim wheels faster?

As cyclists, we know that deep aero wheels are usually faster than lighter, shallower wheels when riding on flat roads. And we know that when climbing very steep roads, lighter wheels will be faster than deeper wheels.

Why are deep rims faster?

Deep section wheels are more aerodynamic than standard box-section road bike wheels. In simple terms, this will make you faster for the same amount of effort. As well as making you faster, there is not a road bike out that doesn't look cooler with aero wheels.

Are deep section rims stronger?

The reason a deep section wheel is helpful is that the deeper cross section is much stiffer, i.e. harder to deflect, than a rim with a shallow depth. The strongest, most durable wheels have deep section rims, lots of spokes (think 32 and up) along with a well designed hub.

Does rim depth matter?

The stability of a wheel is affected primarily by rim depth and profile. The deeper the rim profile, the more aerodynamic the wheel will be, however, the trade-off is that the deeper the profile, the more it will be subject to getting knocked around by crosswinds.

What difference does rim depth make?

Rim depth is broadly speaking a trade off between weight and flat speed. Shallow 25 – 40mm Can be lighter, great for hill climbing and accelerating. Mid depth 40 – 60mm – Is often the best all-round option – relatively light for climbing, whilst still fast on the flat – best of both worlds.

Will lighter wheels make me faster?

Rotating weight only comes into play during accelerations or de-accelerations. Lighter wheels speed up quicker, but they also slow down faster compared to heavier wheels, which speeds up slower but carries speed longer.

How long do carbon rims last?

From ENVE:

This is a good question and one that merits explanation, given that many of us grew up on a 3-5 year lifespan expectation from alloy. The short answer is that a carbon rim is expected to last until it is damaged in a way that compromises the bond between resin and carbon fibers.

Why do carbon wheels explode?

Overheating Carbon Rims Linked to Dangerous Blowouts

The problem has been traced to carbon clincher rims transferring heat to the thin latex tubes, which causes them to either bulge out to the point they deform the heat-softened carbon rim or simply explode–which results in the tire being blown off the rim.

Do lighter wheels save gas?

According to testing by, a combined 3 lb reduction per corner (wheel and tire) improved freeway MPG by 5%. Even bigger savings are generated with city driving as wheel weight is crucial during frequent acceleration and deceleration.

Do carbon wheels go out of true?

Carbon is unlike aluminum in that it will always go back to true if you were to untension all the spokes, aluminum can be bent to the point of no repair meaning that if you release all the tension the rim will still be bent.

Can you use carbon brake pads on aluminum rims?

A carbon-designed brake pad will work on an alloy rim, but since the rubber is harder and designed for higher temperatures, the braking will not be optimal.

What happens if you lose a wheel weight?

The common symptoms of out-of-balance tires are uneven and faster tread wear, poor fuel economy, and vibration in the steering wheel, the floorboard or the seat that gets worse at faster speeds. When all areas of the wheel-tire unit are as equal in weight as possible, the tire will roll smoothly.

Are heavier tires bad?

That added weight can hurt your car’s acceleration and expend more fuel. It can also put more strain on your brakes to slow down the vehicle. Second, wider tires may stick out from the wheel well instead of staying in line with your truck or SUV. This can make your car less aerodynamic and increase fuel usage.
