After a huge dissapointment regarding rider's position, I finally got the risers!!!
I know it's a trite topic, but I think it's worthy.
My doubt was, Rox risers (rise and approach) vs single risers (just rise).
I went for the latter ones, the SW-Motech 20 mm risers, and can't be happier!
It's simply amazing, how much, just a few mm, may improve rider's position! Besides, due to original XC risers orientation (a bit tilted backwards), the SW-Motech not just rises the handlebar, but approaches it aswell!
The position may be properly set rotating the handlebars, which results in an excellent and relaxed position for almost any rider.
The quality of the SW risers is excellent, and the installation is very straightforward.
