Roam 40 Wheels 2016.

OUR OPINION

 SRAM has created a hub 148mm wide to improve stability and ride, reducing the length of the swingarm.
Why the wheels are important?
Here is the Boost Technology!
A very ambitious project by SRAM that the dish of these wheels ensuring more torsional rigidity, greatly improving your driving uphill, but making the bike easier to handle down the hill!
With this wheels SRAM shifts the imaginary line between the cassette and crankset to the outside.
The transmission operation does not change, but with wheels 29 '' and gaining in torsional stiffness you get to the level of a 27.5''.
I recommend: wheels, hub and crankset must be compatible with the Boost Technology.
