Aluminum is known for being corrosion resistant, fairly light and having a high strength-to-weight ratio.
Hydraulic brakes are smoother to operate, more responsive, and require much less brake-lever force to bring you to a stop.
The advantage of suspension lock systems equipped on a Bicycle is that you will get great responsiveness out of the pedals.
