I was thinking about retrofitting my mtb w/ a flipflop hub for some ss/fg goodness once the og drivetrain died, but I'm not sure it'll fly. Conditions range from nice smooth asphalt, perpendicular winds, and near flats, to 10-20mph head winds up ~5% grades of dirt/loose sand. Is it possible to have a reasonable selection of two gears, or will I have insurmountable problems with chain tension unless I'm She-Man and can power up those sandy hills at 400W?Originally Posted by Sheldon
Also, if there really isn't a reasonable combo (i.e. I'd have a way slow city, or way hard climb) could I ream my rear dropouts out into the bike, and tap/thread some screws for adjustment, or would this compromise the structural integrity and run the risk of a warp core breach?
