Overview of components
Fork material
When it comes to the fork, this bike has an aluminum one, which doesn’t add too much extra weight to the bike. However, it is not so stiff as steel or carbon forks are.
Wheels size
The BG Roulux 1 2011 bike is equipped with 700c aluminum wheels when leaving the factory. There is no doubt, that 700c wheels are very popular on all road bike models. However, these wheels don’t perform so well when passing over obstacles.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The BG Roulux 1 comes with Rim brakes. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, you could spend a little extra and get a bike that has hydraulic brakes.
