My initial reaction was "I'd be a little wary", but as I think about it, I'm not sure why. There's no intrinsic reason I can come up with. The FD might help to keep the chain on, and I do know folks who still have one in place with a single ring setup to use as a chain keeper.
There are probably two immediate things which I'd watch for: (1) the angle of the chain when on the inner ring might cause it to catch any "lifters" on the big ring (those ramps and pins used to assist shifting) if you end up in the smaller sprockets in the back, and (2) the ability of the rear derailleur to pick up chain slack when in the smaller front chainring. You might run the gearing through Sheldon's calculator, to see if you are really gaining very much range. http://sheldonbrown.com/gears/ I think if you are just going to use it mostly in the larger ring, and just use the small ring as a climbing/bailout gear (only using the larger three rear sprockets, for example), it ought to work. hope that helps, - Jim -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
