agreed, but it really is as flat as he says it is, he might as well make the jump to single-speed. No point in having all the stuff if it's not needed?jacksonpt said:why does it really matter? I would do it to force myself out of the granny on a few of the bigger climbs, so it would be like a training aid for me. If you are already in the big ring, what's the point?
That's what I was trying to figure out, is there a point?jacksonpt said:If you are already in the big ring, what's the point?
I agree - but he didn't ask about SSing, only goign to a double.LordOpie said:agreed, but it really is as flat as he says it is, he might as well make the jump to single-speed. No point in having all the stuff if it's not needed?
as opie aluded to above... some very minimal weight gains perhaps (unless you have an anchor crankset now and go with a carbon double, then the weight gains would be a bit more)... but probably nothing you'd notice from the saddle, especially if it's flat riding.mogulskr said:That's what I was trying to figure out, is there a point?
I'm almost positive you don't have to change the shifter. At least the 105 is one model and works with both setups.sanjuro said:The cost of switching over to a double is prohibitive. The proper way to do it to replace:
Crankset
BB
Front derailleur
Left Shifter
It's the same. The only shifter that I know of that is double/triple specific these days is DA. That is Shimano speaking, of course. The old R600 was not that way, but everything is now.jacksonpt said:sanjuro - is the ring spacing different on a double versus a tripple? I was considering making the switch at some point this summer if my budget allows, but I wasn't planning on swapping out my der or shifter (but definitely the BB).
Cool - so I can keep my 105 stuff then if/when I make the switch.loco said:It's the same. The only shifter that I know of that is double/triple specific these days is DA. That is Shimano speaking, of course. The old R600 was not that way, but everything is now.
Why?Arsbars said:With the new compact cranks & how cheap you can get them I am hoping we see less and less triples on road bikes.
Loco, DA still works from a triple down to a double.loco said:If it's Dura-Ace, you'll need a new shifter.
Perhaps there is more to your comment, but it seems like that is pretty blind tripple hate to me. Tripples are/can be crucial to someone just getting into riding, especially if they live in an area with little flat ground.Arsbars said:With the new compact cranks & how cheap you can get them I am hoping we see less and less triples on road bikes. There are a view applications that I can see them (Touring is the big one.)
I have never set one up, but would assume it would shift like crap, opposed to a true double shifter. Those micro shifts don't look like that would work well for doubles. I am assuming you are saying it would set up like, say 105, but those don't have the adjustment in the pawls that DA does.Pau11y said:Loco, DA still works from a triple down to a double.
I have never understood this comment. I've never had an issue with triples. I even went and tuned one that they said the DA shifter was broken on yesterday. I run an Ultegra double front der on my compacts with no issues. I don't get why people say you need a special derailleur for them. I don't have any rub on any of the gears. I rub in the 2 high cogs when using the little ring, but that is so cross chained that I wouldn't run it anyway.LordOpie said:<snip>For one thing, I've heard consistently mixed reviews about compacts' shifting. Jumping that big seems to be just as bad as dealing with triple's shifting.
No, I've locked out the lower ring w/ the throw limit screws and it worked just fine.loco said:I have never set one up, but would assume it would shift like crap, opposed to a true double shifter.

I think bibs are the most under-rated piece of equipment.Serial Midget said:Converting an existing triple crank drivetrain to a double is a waste of money... keep what you got and bank your savings for coodinated spandex bibs, jersey & wind shell.

I got my roadie last summer, and wasn't new to riding but was new to the road. If I had a double I would have quit in a hurry. No way could I have survived with a double (even if it was a compact). Even now, after a year on the bike (including all winter), I still need my granny for certain climbs.
I don't remember if it was Truvativ or not but last year there was HUGE ring issues. To the point you would call for an RA on the crank and they would simply send 2 or 3 sets of rings to replace all the other ones you might have in stock.loco said:I have never understood this comment.

Triples is not some magic gear. If you can maintain momentum with a double on the steepest climbs, then you don't need a triple.rooftest said:I did a century this weekend, and was smoking stronger riders on the climbs. I've got a double, while they were riding triples. The double, I think, forces me to turn a bigger gear and go up faster, and makes me a better climber.
OC's pretty hilly, and I've never had to walk a hill yet. (although I have needed to stop and rest a couple times for one hill)
I guess my point is that it seems kind of snobby to say tripples are unnecessary the vast majority of the time. My Quest has a tripple and a standard casette (I think it's 12-25, but not 100% sure), and I walked ALL the good hills in my area for the first season. Now I can ride them all, but I still need my granny/25 for most of them.Arsbars said:My girlfriend just got into road cycling. She lives in upstate PA/NJ and it is a very hilly area. She was pretty out of shape & has a compact FSA with a 12-25 in the back. I haven't seen her walk a hill yet.
They used to have a hill profile, but I can't find it anymore.1.8 miles, the "not so easy" side is 1.1 miles of hill averaging 10.5%, and ending with a final insult at around 19% with another half mile or so to get to the finish
I assume this was directed at me...Echo said:But I don't see why some people are concerned with what others think of their chainring config choice, and I don't see why some people are concerned with what config other people choose for themselves. But hey, I ride a double so I can spout opinions without fear of reprisal
First off - I'm not trying to pick a fight here... sorry if it sounds that way. See my response to Echo as to why I'm drawing this out.Arsbars said:I have "snobbery" due to working on the stupid things daily. Not saying it isn't right for you, but it would be great if some companies would be giving alternative to the triple.

there is absolutely nothing beyond ones opinion. There's no definitive reason, no end-all-be-all answer.jacksonpt said:is there something to gain by bumping up to a double?
LordOpie said:there is absolutely nothing beyond ones opinion. There's no definitive reason, no end-all-be-all answer.
If someone goes double cuz a triple makes for sloppy shifting, then they simply don't want to maintain their drivetrain.
It's a fact that anyone who has a little skill and puts forth a little effort can make a triple, 8-speed Sora drivetrain run fine.
Lastly, I challenge ANYONE who's opinion, for whatever reason, that double is better than triple to go single-speed.
jacksonpt said:I assume this was directed at me...
If he is just expressing an opinion as "I hate tripples", then I don't care. I just wanted to know if there was more to it than that (a performance gain by going to a double... something like that). If it's just an empty opinion, then we'll disagree and it's no big deal - he rides what he likes, I ride what I like.
But if there's some substantial reasoning as to why he doesn't like tripples, I'd like to know.
