With contemporary cogs I rarely miss a shift, and Shifting faster, as I spoke of it, is not about missing shifts, it's about the care and time it takes to shift. On the terrain I was talking about, dirt roads in the Piedmont, where grades are often quite steep but short, and changes are very abrupt, you sometimes have only a very short window to complete a shift and keep pedalling; if you take an extra half second or second to finesse a shift you may lose momentum and bog down, possibly may even have to dismount lest you fall over. I wasn't theorizing in the absence of experience. I have two 650B bikes, a Saluki equipped with indexed bar ends, and a Kogswell with what Riv once called "supermix" shifters: Shimano bar end pods and SunTour Sprint downtube levers. I've taken both on those dirt road rides. Friction is fine on the C&O Canal, where changes in grade are very gradual. It's a whole different story out in Fauquier County only a few miles from the Blue Ridge. I've used the Kogswell to commute on a daily basis, so I'm completely familiar with how the bike shifts; and I used friction shifters for many decades before that, so I'm no novice. It was MUCH harder on the Kogswell; and all too often I found myself being forced to go to the largest sprocket because that was the only one I could count on hitting accurately in the time I had to make the shift. > I can throw the chain across the entire range with one quick move, > which you can't do with sis. You may not be able to do that with brifters, but you certainly can do that with indexed bar end shifters (what I use) and with indexed downtube shifters (which I don't use, but that work the same as bar ends). SIS was Shimano's tradename for indexing. STI is their tradename for integrated brake and shift levers. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
