GMC Denali Road Bike

The GMC Denali road bike is built around an aluminum frame and fork. Component-wise it’s pretty much what you would expect for a bike in this price point. Non-groupset Shimano derailleur and shifters are stock on this bike and the brakes are advertised as “alloy calipers” but there are no other markings that can be used to identify them. The bike rolls on 700c size wheels, which is great since it’s the most common size and there are plenty replacement tires and tubes available. The alloy rims are what’s known as high-profile, this means that they are taller than regular spoke rims. The added height gives the wheel more stiffness and better aerodynamics. High-profile rims can be considered the middle ground between disk and regular spoke wheels.
