I have a 1989 Miyata 615GT. As far as I know everything is stock as is with exception of the cockpit, should I upgrade the drivetrain to 8 speed or tour as is?
Its got a 40 spoke rear wheel and 36 spoke front, the cogs are 13-30 6 speed with 48-38-28 front, I'm sticking with friction shifting as I'm beginning to like it (this is my first bike with friction).
Edit: My possible upgrade include Deore XT rear hub with Velocity Dyad 36 holes, Deore RD, Deore LX crankset 44-32-22 with 8 speed 11-32 cassette. Wonder if I should run the components to ground before upgrading or upgrade right away? Note: I have all of the required parts except Dyad and Deore LX crankset.
