Seems lots of folks are now putting out aftermarket parts for GG but they seem to start at 2001 or so models. Does anyone know if the 1998 rear sprocket is compatable with later models?( I've let my 03 go and never tried to see if they would swap out .) As for entire wheels, I know the fronts are way different due to fork changes but would the rears from later models fit the 98?
