When I first got my bike, it merely had 10 speeds.... yes, the old 2x5. Since, I've moved to a 7 speed cluster for 2x7 which is convenient, especially as I'm getting older.
Originally, it had pretty tight gearing. I'm not quite sure where my old clusters are, but I think the gearing was something like 52/42 x 12/19.
Anybody running a 33 speed bike now?
With a full 11 speeds on a new cassette, I believe the tightest gearing one can have is 11/21. However, the step between an 11 and 12 cog is about 8%, while the step between a 20&21 cog is less than 5%, and it makes sense to start skipping steps, so one quickly ends up with a race cassette as big as the casual clusters of the past.
How long until we start seeing 12 speed and 13 speed cassettes?
Perhaps one could go with a single chain ring, and a bit of a relaxed stepping between cogs on the cassette. Thus, utilizing the entire range on the cassette, and not worrying about cross-chaining. It would make shifting easier.
