What carbon road bike wheel depth do I need?
When the carbon fiber era is coming, what carbon road bike wheel depth to pick becomes a vital questions. In the old alloy age, the rims were very narrow and shallow. So the weight was the primary consideration for the riders. But then carbon fiber took over everything, this new miracle material is lighter and stronger than the metal. It is also easier to shape, which means that the designer spent a lot of time in the wind tunnel. Perfecting the ultimate aerodynamic rim of the road bike.
If you look closely, you will find that the deep carbon fiber rims give the impression of a heavy tire. Those wide carbon fiber hoops are the product of intense aerodynamic development. And their overall cross-section resembles teardrops, rounded at the front end of the curved profile of the tire. Compared with the shallow edge, the elongated teardrop part has different windproof properties. The cross-section may be V-shaped, with a sharp edge where it meets the spokes, or U-shaped, like a wine glass without a stem. Some aerodynamics experts prefer a hybrid combination of these two contours. They say that the deeper the better-the final depth is on the rear wheel. And people might say that the rim profile ends at the hub!
The advantages of the deep carbon road bike wheels.
Let’s take a look at the advantages and disadvantages of deep carbon rims. The advantages of the deep rims are obvious. They can shorten your personal best time by a few seconds, or give you an advantage when resting alone. The farther the distance is, the more energy is saved and the less time it takes. They also increase the stiffness of the wheels, thereby more effectively transmitting power from the pedals. Of course, they may be heavier than shallow rims, but it is undeniable that they cross the finish line first-in some races, not all.
The disadvantages of the deep carbon road bike wheels.
However, there are still some disadvantage of the carbon deep rims. First is the comfort. Extreme stiffness brings a difficult ride. However, the 88mm deep carbon rim is a big advantage in the triathlon riding stage on a flat and straight road in a calm weather. Second, the ultra deep carbon fiber rims become a burden in windy weather. When the wind blows from the front, the deep rim can work well. But when the crosswind hits them from the wide side, they will react like a windmill, pushing the bike aside. When contestants have to work hard to keep the bike in a straight line, performance will be affected.
The pros and cons of the shallow carbon rims.
The shallow carbon rims are lighter. The shallow rims, such as the 30mm carbon rims are easier to accelerate and have less inertia. This allows them to gain a 1/100 second advantage in the last 200 meters of the sprint. On routes like major mountain passes, where large forces climb at speeds below 15 mph, aerodynamics are not a problem. The shallow and light rims help the rider fight gravity. But there will be no advantage in the high speed descent that usually accompanies a steep climb. Click here for some other news in our facebook.
What depth is suitable for you?
Like many other choices in life, the correct rim depth requires compromise. For club riders who like Gran Fondo, 45mm to 55mm deep carbon rims are a good choice. It finds a pleasant medium between the extremes of comfort, aerodynamics and stability. Especially in a crowded army-even when a crosswind hits. For riders who compete and train on the same carbon wheel, this rim will also provide higher durability. Cyclists who live and race in the mountains can walk more shallowly. If a heavyweight professional player is looking for the ultimate rim to use on a flat court in calm conditions, he can choose 88mm carbon rims on the rear wheel.
How to choose the best suitable depth carbon wheel?
