This may sound ignorant, but I don't see enough about X-Fusion and so I know nothing of them. I see Velvets and Vengeance' on dj's, and slope bikes. Which fork is more suitable and why?
Either or is fine, although keep in mind the Velvet is a lighter and XC/Trail oriented fork, whereas the Vengeance is yor AM/FR fork. Being a bit burlier and stiffer, it is nicer for rougher riding applications.
