Ok so now that I have a road bike and I've been riding for a while (and raced once) and I understand how the gears etc work (with a lot of help from this place) I've been getting much better and faster workouts by upping my cadence. That said, now that I understand how everything works, i don't know that the group on my bike was he best choice and maybe I should have upgraded when buying it. Or maybe I have no idea what I'm talking about.
Its a shimano sora 8 speed setup, triple chainring in front 52/42/30 and an 8 speed shimano cassette 11-28. So far I have found no use whatsoever for the 30T chainring or the 28T rear gear (even on the worst hills), however I do find myself hunting for the sweet spot on the lower gears, and I sometimes I feel like I can't find it. I am getting very good at keeping an 80-100 cadence, but sometimes its just not right and I feel like I'm over or under driving myself.
So now I look at gears, and I see these 10 speed cassettes 11-23 or 11-26, seems like a lot more options! A double front chainring is fine too, since I never ever use the smallest.
Am I right in assessing my situation? HOWEVER I guess the bad news is I need to replace almost everything (besides the brakes) to switch to such a setup. I've been looking at SRAM Rival... and wishing I had just ponied up the extra few bucks when I bought the bike.
