Ultegra Cassettes..what to use for flatland training/racing?Wallace
Jan 23, 2004 6:48 AM
Currently I run a 12-25 in the back. I'm looking to upgrade with a different one. This is not to say my old one is bad, I just want to try another option. With the different choices I have for cassettes, which one would be a good setup for the open roads/rolling hills of Illinois? What do you recommend or use? Thanks in advance.
11-23 is one of the most popular....Doc Hollywood

If the terrain that you are riding is pretty much flat with some minor rollers and you favor power over spinning, 11-21 is nice too. With an 11-21, and 9-speed, you get a 1-tooth increment increase for each gear. This makes finding the "sweet" spot for your cadence easier.

Your missing the 18 with 11-21, need 12-21. nmTFerguson

Do you use 12? Do you use the 25?Spunout

Don't drop the one gear easier than you normally use, you might need it someday.
Agree with SpunoutChen2

Too many riders buy gears based on what the pros use. Get what you really need. A 53 X 12 combination gives you 35.5 mph at 100 rpm cadence. How fast do you plan to ride? I believe in being realistic. I use a 13-26 and 13-25.
Same here....PEDDLEFOOT

...I think you're more likely to use the easier combinations than the hard ones.I use 13-26 and find I'm using the 26 more than 13.
