Phil,

That's what I'm looking for. As it is now I'm in the big ring in front and pedaling like hell in the smaller cogs. I have a road bike with bigger front rings and can get plenty of speed using the big ring and staying in the middle on the back cogs. I run marathons and have plenty of endurance so I don't think it's a fitness thing. I like to maintain a cadence of around 90 as that seems to be about right for me. I'd just like to maximaize that cadence. Like I said, I'm new to this mechanics stuff and really have no idea if changing rings and gears is the answer.

Thanks.

Jim
