P.1 components
Fork material
When it comes to the fork, this bike has a steel one, which tends to be more flexible than carbon forks in general. However, a carbon fork is considerably lighter.
Wheels size
As for the wheels, Specialized P.1 2012, has a 26″ aluminum model. Being a little smaller, these wheels will fit both small and tall riders. However, you will need increased suspension than in the case of 29″ wheels.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The P.1 comes with Mechanical Disc brakes. They are much easier to maintain than hydraulic disk brakes. However, performance-wise there is room for improvement.
