running a 2-5 on my bike, would do it again in a heart beat, rode about 40 miles of trails with it and did not have a single problem, if you go with a 1-5 or a 2-5 you lose 6th gear, but if you go with a 1-4 you can clutch shift 5 and 6th. let me know I can get you the number to a guy in florda that can hook you up with any of the above.
