Hi, I came across your for sale ad on a 2001 Specialized Enduro Sport. I have the same bike and have thought about upgrading it. I've already had a newer 2012 full suspension trail bike so I'm think to make it a backup bike as it seems I can't get much money from selling this old Specialized. How did the rear disc brake work since it uses a conversion kit to mount the caliper? Were there any issues you had experience? Thanks and hope to hear from you soon.
