What size cassette are you using?

...and why?
I think my current setup has a 12-25 on it, but I also have a triple. I'm switching to a 53/39, considering going to 11-? I'm just wondering what everyone else is using?

12-27 with a standard 53/39 crankset.

I use them all. I have never "needed" a 53x11 when catching up on a descent in a road race. I am probably going to put an 11 on my TT bike though, since I don't want to be spinning like a madman to get a few more MPH on downhills. As it is I use a 54/42 on the TT bike.

As far as the 27T cog goes, I use it quite often in training, less often in racing, but there are definitely sections of RR courses in NY state where I need the 27T. Most notably the wall in the Owasco Road Race which has sections of 20% or more. At the moment, I have no intentions of changing my gearing, since I am just getting to the point where I can do L2 rides on hilly terrain. Once my power goes up to perhaps 4.5 w/kg at threshold then I could see changing to a tighter cassette.

12-25 for most races. 13-26 for cross, 12-23 for crits (I'd rather have an 18 than an 11)

11-23 for most races. 12x25 for training, and the rest of the races.

Edited to add.... can this be moved to 41?

It makes no difference what I use. I live in Florida where it's pretty flat, and the few hills we do have are short enough that you can just muscle over them in 2-3 minutes.

If you live in a flat location like me, then 11-23, or 11-21 is probably ideal. Maybe 12-23. If you live some place hilly, you'll want something else.

11-23 9 speed with a 50/39 semi-compact...means I just changed my 53 for a 50. I usually always raced on this gearing regardless of the race but for races like Streaked Mtn, Putney, Fitchburg, Killington, Smugglers Notch, etc. I would use an 11 or 12-25.

52-39 with a 12-25 cassette. 39-25 is low enough since it is pretty flat by me and 52-12 gives enough top end not to spin out.

I'm going to have to spend some time in my 52x12 to see if I'm actually spinning out or not (descending). I'm pretty hilly here, so maybe by dropping the triple, I should go all the way up to a 28 in the back? Hmmm...why is it that NONE of my decisions regarding my training/racing can ever be EASY??!

53x39, with either a 11-21 or an 11-23 in the back. I run a 46x39 and a 11-25 for cross. They get me up even the steepest hills around here.

Begin the accusations about how I'm a liar.

12-25 on a 53/39 for racing and training. I will be putting a compact crank on though for longer climbing training rides. I'd like to be able to do some 10,000+ ft rides without hurting my knees too much.

I use a custom cassette that's just 11s all the way across. I filed a tooth off one of them, so I've got a 10.

11-28 8-speed, because I can get up most of the hills with the 42 little ring, gonna get the 39T little ring on there soon and will climb all the hills with ease

13-25 7-speed, because that was on the wheelset that came with the bike. They're sewups, so only for special occasions.

This is me on my road bike. I use the 11-23 for crits and the 12-27 is on my 'climbing' wheels. I've got some really steep hills that I train on sometimes, and I just gotta have the 27 for that (OK, the 26 would probably work, but....). The other 2 are just really good all-rounders.

I also have an 11-32 8-speed on the 'cross bike. I=Wussy.

After today's ride, I found that on some of the steeper descents, I am spinning out. My big ring is currently a 52, so maybe the 53 will be all I need to gain a little more on the downhill.
I think I may try a 12-28 once I make the switch next month. Some of my local hills are beasts. Thanks for the info...

You should spend some time working on spinning past your comfort zone. I think just about everyone has over 150rpm in them if they work at it, and I would think 200rpm is likely for lots of riders.

Still, nothing wrong with a 53-11. It helps me keep the power up on steady SST rides even when descending some steeper hills.
