Subject: Q: Lower Gears on Campy Setup
|
I'll give a little background to this question, and hope the babbling isn't irrelevant or boring. I'm a road cyclist in a club, a little slower than most of the folks strong and crazy enough to do the club's most difficult rides. The bike is a Campy Chorus / Record Habanero with standard 39/53 12/25 10 speed powertrain. I go out of my way to attack the hills, having a little over 200K feet of climbing this year to date. While I try and keep a reasonable cadence on the flats, I'm a "masher" on the hills - standing up for most hills, even as silly as freeway overpasses, and willing to stand on it in first gear for several miles if that's what's necessary to get up a significant climb. Maybe that's not ideal in most folks' book, but that's what has always worked for me and that's just the way I do business. The 25 cog has always been sufficient, perhaps with some pain but nothing I can't handle. In general, I stay out of the small chainring except as climbs get steep or, rarely, if there are bizarrely strong Santa Ana winds in my face. But recent situations lead me to ask about lower gears on this setup. Three times in July I tackled what's considered one of the more grotesque climbs in Southern California - the climb to the Mount Baldy ski lifts on top of the normal Glendora Mountain Road jaunts. For outsiders, picture dead Sherpas and quivering yaks, hooves up, strewn by the side of the road. It's really a significant workout, and I'm apparently doing it again this weekend. Doing it in that 39x25 is almost absurd for someone who's not a finely honed athlete. My frequent riding partner, one of only 20 women crazy/good enough to earn this year's "King of the Mountain" title (three centuries, 30,800 feet of climbing) could barely get up that climb in a 34x30 and nearly cracked. I realize that if I'm going to earn that same jersey next year, and I'm leaning toward trying it, that there's no way I'll be able to grind out that many miles and that many feet of climbing in a 39x25. Can anyone suggest the best way of getting somewhat lower "emergency only" gears on that Campy setup? I know there are those "newfangled" compact cranks, triples (which rub me the wrong way), different clusters, and perhaps other approaches. Again, I'm in that big ring most of the time and would prefer to minimize front shifts; the old half-step days are long gone. Appreciate any "here's what I'd do" advice. Art

It also sounds like you and I are in the same boat as far as who we ride with and the style and type of riding we do. I can hang with the cat 3/4 guys on a flat course with my compact double. Think about your reasoning on this one. How long would you spend in the 50x12 compared to the amount of climbing you are going to do in the 34x26? Now, ask your knees the same questions and see what they have to say. I went from a triple on my old bike to the compact double on the Habenero and frankly, I don't want a triple any more. If you really need to have that much speed on the downhill, learn to tuck and daft. You can still get to 31 or 32 without spinning out. OK, you will have to quit pedaling a mile an hour or two before the others. Is that really going to cause you to get dropped? Your knees will love the bit higher RPM's you can do and still maintain a decent speed along the flats. A compact double is the only way to fly.

If you search this ng, you'll see reference to successful use of short rear derailleurs with 29t cogs, and also with triples. IMS, both of those combined will also work. IOW, the only component you'll "have" to change besides the rh crank and possibly the BB would be the front derailleur. There's a lot more inner cage on those triple fronts. Hey, a triple, with a 42t middle, and a triple front derailleur might be an improvement all the way around for you. A low low, a more usable, 42t inner ring, compared the to the 39 you don't use much, and better (presumed) shifting from a triple front derailleur. Um, "Fred" uses big gears he can't turn. Or stomp, either. <g > --D-y

Point being, you get to keep the gears you use, plus add a low low. If this is something you only need once or twice a year, it might be possible to keep say, a Veloce triple plus BB in reserve, maybe incl. pedals, and do the switch when needed. (Said as a longtime "42" user who still isn't used to that much- appreciated 39 I've had on for years now): A compact setup, for riding with fast groups? Might work fine, or you might not like it-- "always in the wrong gear". --D-y

Might work fine, or you might not like it-- "always > in the wrong gear". For an 'event' gear format change, Veloce and Centaur square taper series cranks use the same spindle length for double or triple. So it is perhaps just a right arm with rings, depending on your opinion of shift response. A double front may be useful if you remember to use the inside ring only with the largest few cassette cogs. Simply changing your gear train over to a triple setup isn't a bad idea either. Cranks, FDer, maybe RDer. Chain length doesn't change for double to triple as your largest combination is the same. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971

Well, I appreciate everyone's input. Not sure what I'm going to do, but you've presented some nice suggestions. Tom, I'm sorry, but I don't think that Schlumpf product is intended for a light road bike. Let's see: the compact crank might be the simplest solution, but I could never live with a 50x12. No, I don't use it all that much, but it doesn't take much of a hill to get into the 30 mph+ range where it's useful, and if I can hang for a while with the faster riders in the club they'll routinely get into the low thirties on even a slight grade. I could go with the 11 tooth cluster, which would be fine, but then I'd be limited to a 23 biggest cog, which defeats the whole purpose of this exercise. Triple: Chorus and Record seem to be 175mm only; I ride a 172.5. *Major* cost - the whole powertrain. The 42 vs. my 39 might actually be an advantage - it would probably get used more and there would always be the small cog. Satisfies all the requirements. Seeing how poor front shifting is already, it would probably be worse news with the triple. More weight to drag around. Fred factor to some degree, although I accept your assertion that even the pros are using 'em now. Would probably let me power up to the ski lifts sitting down and whistling a happy tune. Bigger cluster: satisfies requirements, simplest solution, far less cost than the triple. Could live with a 13 cog smallest gear for the times I use it. Would require two chains (and thus "masterlinks") and ideally two derailleurs to not use the medium cage derailleur with the 25 cluster for best peformance (I assume.) If I go that way, what's the best connecting link for a Campy Record chain? That would also maximize cleaning ease - easily take off the chain and toss it in the ultrasonic cleaner like the "good old days". I'm not willing to swap out cranks - they're simply not intended for frequent removal. Other option: leg transplant with world-class cyclist. Allows use of current setup. Disadvantage- time off bike for healing, difficulty procuring donor, company insurance probably will balk at paying. Art

Can't help with your decision but take a look at a 2mm spoke. That's about the crank length difference you note. If it matters, buy the Record triple 172.5 which we have, as will any competent LBS.

When torture comes, I use a Shimano 9, 12/27. I replace the 12 with a 13 and add a 32. You can use the std. cage Campy rear derailleur and may not even have to add a link of chain.

I have two bikes with triples on them, so I can use a 30 x 26 when I need it. No matter how it "rubs" you, even the pros have used triples (the Vuelta a couple of years ago comes to mind). Many people are surprised to see that I have triple chainrings - a lot do not notice. Because I've lost 20 pounds since mid-March, and improved my core fitness, I'm contemplating changing one bike to a compact double chainring and a 12 - 23 cassette. (I'll also get a lighter pair of wheels than that bike has now.) That will suffice for many of the So Cal climbs I do regularly - Turnbull Canyon, Santiago Canyon, and the like. You could go to the compact chainrings and a 26 or even a 29 cog in the rear, if that gives a low enough gear for your fitness. Several of my riding buddies use the compact drivetrain (and they include women who climb like mountain goats) with success. But when I see you on GMR, I'll still be on that triple, just in case I decide to turn up the hill when I reach Mt Baldy Road.
