what's the difference (besides the obvious)?
which one?

ps. the bike i take out of town for long rides over unfamiliar terrain has 105 triple, and i've used the small chainring on large bumps in the road.

Last year when I bought my 10 spd. I was told that 9 spd was hard to come by. Hence I dropped the triple and went 10.

You can get just about the same gear range using a 10 spd. ie from memory my set up is 9 spd 30-42-52 12-23 gives me a low of 1.30. My 10 spd 39-53 12-25 gives me a low of 1.36. Granted I'm a climber but I have only found one hill I could not get over in a 1.36. I recall it was something like 18%.

I hope you're not thinking of putting a triple on that Merckx. Unheard of. Eddie would slap you silly.

I opted for the Chorus 10-speed because I wanted some good climbing gears but I didn't want a triple. So I got the Chorus 10 with the 13-29 cassette. It has almost all the gearing of the triple without the hassles -- that is, the fussiness in getting derailleurs adjusted just right. Most people I've talked to w/triples rarely if ever use the small ring (for that matter, I rarely use my 29 gear.) The Chorus triple also uses a lower-quality bottom bracket, comparable to Daytona.

I'm not positive, but I think the biggest gear you can get with the 9-speed is 26. If I'm wrong, then you would have more gaps with the 9 speed. The one advantage of the 9-speed (other than lower cost) is the chain. The Campy 10 chain is a pain in the butt. It's more expensive, apparently doesn't last as long, and requires a special tool to change it. (I don't know what happens if you break the 10-speed chain out on a ride.) My 10-speed chain has about 3,000 miles on it and is starting to shift a little funky at times, even though I've cleaned it regularly and kept it well-lubed with ProLink.

Now, my question for you, is how did you talk your wife into getting you a Surly Steamroller -- as well as the Merckx? You must have accumulated some serious brownie points.
allowance...and plausible deniability!Js Haiku Shop

as in, "what you don't know won't hurt you."

we're setup on an allowance scheme, like a 9 year-old. this is by design, as, when we moved in together, i was pretty bad with money (making plenty, blowing most). i gave her my checkbook and asked her to pay the bills and set me up on a regular weekly allowance for gas, cigarettes and miscellany. now that i don't drive so far, and don't smoke anymore (several years now), the weekly monies go mostly toward pabst blue ribbon and cycling stuff.

now that i'm a grown-up (big 3-0), i negotiated a raise in allowance and additional ways to make more money, as in doing her chores 'round the house as well as mine. sometimes i feel like all i do is clean, and need one of those french maid outfits. then, i remember the hassle from MB1 about the pantyhose for cold weather riding, and forget about the outfit. d'oh!

the merckx will be paid for, with chorus, and shipping, but will take several months. i didn't necessarily tell her it was another bike, just that i'd be saving a couple grand in my piggy bank from weekly allowances. another thing i'm doing to afford the merckx is eliminating out of town rides for the majority of next year. $35 entry fees aren't that bad, but traveling, hotels, meals and the rest add up.

what else, pray tell, would i do with a couple grand? i could invest in crack, but smoking it melts my teeth. ;o).

I have a Racing T/Chorus triple set up [phil wood bb] and I like it. Actually there's nothing wrong with the ACH Daytona/Centaur bottom bracket, though. I don't race, just ride as hard as I can, and I don't want to have to get off the bike and walk up a hill - any hill. The small ring is good to have when you need it. I'm running 30-42-52/13-23. Plenty of low end. Shifting is no problem. If you're used to a 105 triple, and want to change, I'd go with the Chorus 9 speed triple. Just my experience - 2 cents worth.

I've had the Chorus-Racing T on my last two bikes, and it works fine. I live in a place where I don't get to ride very many serious hills, so for trips where there's extended climbing the triple makes it easier on me and my old knees. (I can sit and spin just like Lance, only at less than half his speed....)

No mechanical problems (except a cracked left crank--I think they've changed the design since) and easy to shift and trim. Lots of gear choices.

The best thing to do is to compare the gear-inches for each setup, double or triple. To do that, go to

Unless you are doing some serious mountain climbing you can probably get by with a 13-29 cassette.
