Subject: RE: Double or triple crankset - does it really matter? it gives you a wider range of gears to use. If you want to get technical, there is a different amount of teeth on the rings and the same is true with an 8 or 9 speed cassette. I can't think of the numbers off the top of my head. Maybe someone who can will jump in soon.
That being said, I have a triple and rarely use the "granny" ring. But I went into the bike shop and said, hey I'm a girl, give me a triple! I think if I was to ever buy another bike I'd get the double.
I should say "technicall" it gives you more gears to use. But realistically, you lose a few due to the angle of the chain in certain gears. The chain ends up rubbing when in the big ring and the smallest part of the cassette. Same is true for the smallest ring up front and the biggest on the cassette. So I find I don't even use them. But the granny gears are nice when you want them for hills.
Help.....I think I'm rambling.....
