I got my Fuji Touring Series III from eBay today (will start a separate thread since lots of folks seemingly like my cleaning exploits ). Very dirty, reminiscent of the 85 Club Fuji I worked over, but otherwise in fine shape.
It has a Suntour 6 speed drivetrain (Mountech FD/RD, 6 speed cluster, 50/45/28 crank). I've read that some folks have used Shimano Hyperglide freewheels to improve the shifting performance over the straight toothed Suntour freewheels. Also, I read that 6 to 7 speed generally isn't a problem, in friction mode of course. I'm 90% sure I'll be using Suntour ratcheting barcons.
Any truth to this? And yeah, this might be putting the cart before the horse but since I'll be going back to my co-op treasure trove either today or tomorrow I figured I might look for a nice Shimano freewheel is there's any truth to this.
Oh, and yes, RD alternatives have been examined and explored although the Mountech currently installed is smooth as buttah, for now right?
