I met up with my biking friend John T after work today. He was excited because he made a major change on his bike: he got a new cassette.
I’m sure it will. When I got a new cassette more than a year ago, the bike shop found one with a 28t cog. A 26 was the largest that came with my bike. I couldn’t climb Heart Attack Hill with the 26, but I can with the 28 (and better conditioning).
In fact, my cassette has a wide range. Its smallest cog is an 11, so its progression is 11-13-15-17-19-21-23-26-28. Yes, nine speeds. I like it, because I can really fly in the big ring with the 11t cog, and the 28 gets me up the hills. But lots of bikers hate wide range cassettes.
Their concern is with the gaps between some shifts. I have two-tooth jumps in most gears. A lot of cyclists will tell you they prefer one-tooth jumps — that wider gaps like I have make it hard to figure out just what gear you should be in, and that means more shifting between the big ring and small ring up front.
So, the more gears you’re running in back, the tighter your cassette will be. Another option would be a triple up front with a tight range in back. The small front ring will get you the granny combination you’ll need for climbing.
Both John T and I run 50/34 compact cranksets up front. We’re not racers. We’re not climbers. We both need help on the hills. For us, a wide range cassette works.
What do you run on your bike? What do you see as the pros and cons of wide range versus tight range cassettes?
