Would it be possible to run 11-speed with just the purchase of a chain, cassette and right shifter? Anyone try this yet? I'm guessing it would be no problem.
Yeah, I'm thrifty!
I imagine you’re talking 2009+ 10 spd Veloce, Centaur ? I doubt you'd consider an old style front brake/shift lever and new style rear.
I upgraded a friends bike a couple years ago from old style 2004 Record 10 to 2010 Record 11 and played with swapping rear drivetrain parts one at a time to see how it would work, only spinning it on the stand so no road test. I have two recommendations below based solely on that one experiment:
1. Put 11 spd derailleur pulleys in the 10 spd derailleur. 10 spd pulleys are too thick to efficiently run the 11 spd chain. They kind of work, but not really. Even after the swap the 2004 derailleur was very vague, shifted poorly IMO. The 2009+ design is considerably more rigid.
2. Need newer rear derailleur cable housing to fit new style shifter. Old derailleur housing has a larger Ø than the 2009+ stuff. If I remember correctly the cable fit fine. 2009+ 10 spd would have come with the smaller housing.
I may source a shifter at some point and a chain and cassette and try it out. Ten bucks says it works fine. Solo shifter show up all the time on ebay and I already have a couple sets of the new shape floating around so that's all good.
We'll see what happens...
Mine ran FINE on 10s cranks and FD. In fact, it ran perfectly, such that I'd say it was a total load of crap that you'd ever have needed new chainrings, etc. (Besides, the ramps have changed, but the rings have not - not really. It's the spacing on the spider between the rings that slightly different.)
Then I switched to 11s SR cranks. Then I had to switch to an 11s FD, too. Now it's mostly fine again, but front shifting isn't quite as instantaneous and trim-free as I had it running with the 10s cranks and FD.
In my opinion, the 11s shifters are so good I don't know why you wouldn't switch - and I was a longtime 10s holdout.
Other than adding a gear are the 11-speed shifters different than the Centaur 10-speed shifters of the same shape? I find the Centaurs decent but the feel of the shift less precise and more plasticky than the Record 10s I can get used to it and it's no biggie.
I like the new shape but don't find it massively superior to the old shape. To my hands it's just a different feel, not a better feel.
Dave's post in another forum I tried it and for several reasons ended up going with a Chorus 11 rear.
We'll see what happens. Today I installed a set of 10-speed Centaurs on the Zanconato. They are indeed nice. Maybe I was ambivalent about them before because the bikes I had them on fit less than ideally, which is not case with the Zanc. Anyway, it is transformed. I knew the 10-speed Records were in need of a rebuild but I don't think I knew how badly.
As for 11-speed, there's no rush on any of my bikes but when I need a new chain or cassette on the Pacenti I might give it a shot.
Do you say the same assinine things to those who mix Shimano cassettes with their Sram groups? Or use connector links? Or use aftermarket cable sets?
Using a 10-speed der with an 11-speed cassette (same exact width of cassette) hardly seems high risk..... I'll take my chances.
if you really believe you need 11-speed chainrings to operate an 11-speed drivetrain, you are a marketeer's dream. as the saying goes, it is not difficult to separate a fool from his money.
note that i say that with all due respect, honestly. it is one thing to want to do everything "by the book", but the real world reality is that some stuff just works, despite what the technical manual says.
by the way, last night, i opened my beer bottle with the back of a bic lighter. it worked out OK.
AngryScientist, you should be careful opening beers with lighters: you can skin your knuckles, and wrongly inspire others to do the same.
