Am a disabled bike rider ( use of one arm ) presently run a specialised hu8 shimano equiped hub gear . I have been an active club member for 30 years, and have difficulty keeping with derailure equiped bunch. The reason for choice of hub gear despite well versed practical application,s is the simplification of physicall input when changing gear. ? Has anyone any expierance in maintaining the pace on a club run. ? is the RST a suitable mount ? is there any need or plans to manufacture an RST with 700c wheels,and equipe it with calliper brakes, ps The hu8 was purchased as a cheap option to evaluate the practicality of an RST.. Any infomation will be much appreciated, Cheers JIM.
