road/cross bike: which XT cassette, and why?(20 posts)

road/cross bike: which XT cassette, and why?JS Haiku Shop
Aug 15, 2002 6:00 AM
this will also be my "really freakin' big hill" bike, randonee bike, rain/winter bike, trail bike, and everything in between. 9sp ultegra triple, xt rear derailleur. and i like having low gears, thank you very much!

11/32: 11-12-14-16-18-21-24-28-32
11/34: 11-14-16-18-20-23-26-30-34
12/34: 12-14-16-18-20-23-26-30-34

the 11/32 looks like closer spacing at the bottom of the range, but i'm not sure how much i'll acutually use an 11. my current primary road bike has 13/29 (campy 10, double), and it's fine by me (the 29, that is! 13-14-15-16-17-19-21-23-26-29).

TIA!

Fool around with all your gears.MB1

How about a nice 12-32. Make it by fooling around with a few cassettes. It wouldn't hurt to run a 26/39/48 set of chainrings too. That way you will have gears you will actually use.

I ride in the dirt a lot in the winter with those gears and Avocet Cross 700X38 tires. Off road is really fun on a cross setup.

All that stuff is available on-line from Peter White Cycles or Harris Cyclery.

BTW have I ever mentioned that you can get a fixte cog and lockring from Harris Cyclery for about $25.00 (since you are sepnding money and all....(fixte in the dirt is great fun)).
might consider that down the road, but...JS Haiku Shop

the options i have at this time are stock, off the shelf. it's part of a build kit, so i'm picking from the standards.

LOL: i'll get that steamroller fixed, my kilt-clad friend. don't you worry your chicken legs about it! you should never have posted that pic. i've been having problems sleeping ever since. food doesn't taste the same, either. kind of the same effects as when i quit smoking (cold turkey, might i add).
Check it out.MB1

Harris cyclery builds custom cassetts for a fair price. Worth a try.

BTW #2. So you dream about me do you???

but sometimes i sit bolt upright at the office, cold sweats, chills, fever, the like--my coworkers often find me rocking back and forth in my chair, chanting "noooo kit...noooo kilt...chiiicken legs..."

you get the picture.

39/29 is roughly the same as 30/22dzrider
Aug 15, 2002 6:19 AM
I guess the question is how easy do you want it. I have a Campy 9sp triple and a 12-23 most of the time and a 12-27 for touring. I've never mastered spinning at very low speeds and it sounds like you have, so you may want bigger cogs. I'd try the 12-27 first, you may be surprised at how easy a gear 30x27 really is. I agree with you about the 11, they're made for mtbs with little bitty chain rings.

i've used 30/27 before, and am getting 30/32 or 30/34 for a reason--the reason is 'cuz i climb like a brick. actually, i'm a moderate climber for my size (imho), but little hills get pretty tall after long miles.

thanks!

I'd go with 12-27. As a randonee bike 30/27 is enough to climb trees sitting; given the steepest paved climbs even bonked, hurt etc, etc, etc. Unless things get really bad granny won't see any action.

For cyclocross you don't need as low gear, cross events are short and you more likely to loose traction and end up running.

Personally for crosser I'd go single (36-38t) or double (42/32) chainring set up, and 11-34 in the rear, more clearance then 52. Probably the easiest would be to get MTB double cranks (Coda makes 44/29) or triples w/o granny good luck

also, Rivendell is selling those really nice Ritchey double cranks with the 110 bolt pattern.
ok, then...can xt w/triple front address steeper cassettes?...JS Haiku Shop
Aug 15, 2002 6:46 AM
if i wanted to be able to use 11-32 sometimes and 11-23 sometimes, just for example, are the xt rear der and ultegra triple compatible with the steeper cassette option? i know it's all 9sp, but i'm asking about reach and all that.
Yup (mn)Spoke Wrench

I have that exact set up on my Gunnar. Ultegra triple, XT w/ 11-32 on the back. Shifts great, and it'll definately get you up the "Oh my God we're riding up THAT?" hill. Needed it yesterday on a 4.5 mile monster in my back yard.

This late in the season I find I don't use the two lower cogs as much if I'm in the granny, but like them if I want to stay on the middle ring. Guess I'm ready for a double huh?
I should have done it ! :-)PeterRider

Recently, in the mountains behind Pasadena, I was going at 4-5mph in my lowest gear (30-27)... maybe it was the heat or my bad legs, but I was really wishing I had a quadruple instead of a triple ! :-)

With a 30/32, I bet you're going slower than walking ! :-)

Nope. I spin pretty fast.theBreeze
Aug 15, 2002 1:54 PM
The slowest I've ever done in my 30/32 was 5.5 mph up an 11% grade. When I usually kick it onto my granny ring, for instance on a four mile 7% grade I regularly ride around here, I manage to keep it around 7 mph. Like I said I could maybe get by on a double on 80% of what I ride. I'm starting to ride some of the steeper stuff in the 30/24 or 30/21 or 42/32,28. Kind of weird I know.
Customize!LC

The 11-32 XT is made for 22/32/44 chainrings. For standard road you will have to customize to keep the gaps closer. Get the 11-32 and also a 12-21. Now you can put it together any way you want. I would suggest 12-14-15-17-19-21-24-28-32
It's never as easy as that.Spoke Wrench

At least with Ultegra, the 18, 19 & 21 are going to be revited together. There is a 17 & 19 two cog combo, however, that I think comes on a 12/25 or a 12/27. It looks to me like to get the combination you indicated in Ultegra/XT quality you would either have to mix three different cassettes or buy the individual cogs. Buying the individual cogs would cost about as much as two cassettes, but then you wouldn't have all of the necessary parts to make a 12/21.

Aug 15, 2002 11:04 AM
Your right. I have a whole pile of various cassettes that I piece together. With the 12-21 and 11-32, plus whatever he has got right now, there will likely be a combination that will be perfect.
Sounds like my setup ...IFRider

My Paramount has a Campy 10 speed double with a 13/29. That is my nice weather cruise fast bike. I have also have a "really freakin' big hill bike, randonee bike, rain/winter bike, credit card touring bike" which is a Independent Fabrications Club Racer. Built up with long reach brakes for fenders, room for fatter tires and braze-ons for racks and panniers. I have been running an Ultegra Triple with the 12/25. For a recent trip to Vermont (Waitsfield and Stowe) I swapped out the rearend for an XT derailleur and a 11/34 with a new chain. I found the range perfect for long days and big hills with lightweight panniers. Shifting was great although I needed to adjust the b-screw in all the way. You can get up most anything and shifting is great. As far as a range goes, I do miss the closer cassette and do plan on switching the derailleur, chain and cassette back for most of my local riding. I have a couple of craig superlinks for swapping the chains.
thanks, all, for you input...JS Haiku Shop

11/32 it is. i can change later if desired. i'd rather have a pie plate and not use it than need it and not have it. i love to ride, but really despise walking.

another good point that was made: loaded touring. be it with panniers or a trailer, i'd rather have the low gears for multi-day or encumbered rides.

thanks again!
