Four Corners components
Fork material
The fork on this bike is made out of steel, which tends to be more flexible than carbon forks in general. However, a carbon fork is considerably lighter.
Wheels
When leaving the production line, the Four Corners model has 700c aluminum wheels. There is no doubt, that 700c wheels are very popular on all road bike models. However, while they give you great speed and control, these wheels are not so bump-friendly.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The Four Corners comes with Mechanical Disc brakes. They are much easier to maintain than hydraulic disk brakes. However, performance-wise there is room for improvement.
Sizes
Four Corners comes in 4 sizes, that range from 158 cm – 199 cm (5.18 ft – 6.53 ft). In short, it won’t be difficult to find the right one for you.
