new cassette: 11x32, 12x23, 12x25, 13x25 or 13x23 ?Haiku d'état

i'm running 12x27 now and rarely spin-out on the 12. i use the 27, but not often. nashbar has the hg70 9-speed, but only in 11x32, 12x23, 12x25, 13x25 and 13x23 ($34.95). what say ye?

also, i've never done this before. assuming i get the park sprocket remover and a nashbar sproket tool (i need two of these, right?), what else do i need?



i'm also picking up the 9-speed hg70 chain and already have the park chain tool.

thanks, all!

The only tools you need are a Shimano Hyperglide lockring remover (Park Tools FR-5) which, like its name implies, removes the lockring that holds the cassette on. And you need a chainwhip--one will usually do.

If you have a 12x27 and don't use the 27, get a 12x25. You'll get more useful gears and better spacing because your 12x27 went 21-24-27 while the 12x25 will go 21-23-25.

If you have a 12-27 and it works well for you why change?
A bunch of online stores have Ultegra cassettes (including 12-27) at $39 (take a look at coloradocyclist.com or performancebike.com) - probably not worth it save $5 to get a 105 cassette in a size you don't want anyway.
And, you will need 1 lockring remover tool (Park is the way to go) and 1 chainwhip.

For Freehubs, the reason Park says you need 2 of their chainwhips is that the end has a socket that perfectly fits the Park FR-5 (Shimano lockring remover tool), however, all you need is an adjustable wrench to turn the FR-5 cause you are obviously using the chainwhip to hold the cassette.

I have a 12-27 on a pair of Speeddream Aerolights (touring/commuting) and a 11-23 on a pair of Zipp 404's (race wheels)

you say you use the 27 but not often. Consider the fact that there may be times when you need it. I'd find another source for parts and stick with the 12-27. That's what I have, and I rarely use the 27, but I'm damn glad it's there when I need it!
thanks, all--i've placed my order...Haiku d'état

ultegra 12x27, price match with performance for $39.99, park chain whip/lockring wrench thingy, lockring remover #5 for hyperglide, and a chain (and some other stuff).

once i see how easy it is to replace the cassette, perhaps i'll save my pennies and get another cassette or two for different rides/times of the year. hmmm...

your help is much appreciated!!!

how 'bout 13x27?cyclopathic
Aug 7, 2001 1:11 PM
oops they dont make one!

there's not much diff btw 12x27 and 12x25, only 2 larger bailout cogs
24 and 27 vs 23 and 25. 12x23 has a very useful 16t cog, and 13x23 has 16t and 18t (with 53/18t being almost equal to 39/13t)

I had the same dilemma and I end up buying 13x23 and swapping lockring and top 4 gears (12,13,14,15) from 12x27 to lockring and top 4 from 13x23 (13,14,15,16). This gives me best gear for hilly centuries, yet enough close ratio gears for riding flats

Get the Ultegra for about $39.95 @ Supergo or colorado cyclist. They have a 12-27, for sure. Why mess with something that you like?
got it. thanks! nmHaiku d'état
