Overview of components
Fork material
The fork is made out of carbon, so, it’s a great addition to the bike’s value. However, carbon forks should be regularly inspected for damage because even the smallest crack could cause the fork to fall apart.
Wheels size
When it comes to wheels, the Threshold A Tiagra bike is equipped with the 700c aluminum model. These are the most popular wheels for road, aero, gravel, cyclocross, race, and gravel bikes. However, while they give you great speed and control, these wheels are not so bump-friendly.
Brakes
Stopping the bike when needed, it’s essential for your safety. This bike has Mechanical Disc brakes. They are much easier to maintain than hydraulic disk brakes. However, performance-wise there is room for improvement.
