Have a nice new frame. ALso have a nearly new 3x9 xtr group. Can anyone tell me major disadvantages of using this on the frame? Everyone seems to run 2x10 and the top bikes these days all come with that as standard
thanks
I'd just stick with 3x9 if you already have it, few if any actual advantages on 2x10 just more usable gears really as less chainline issues + maybe a tiny weight saving.
I've put 3x9 xtr on my 29er, no problems..it's just gears. 'click' easy gear.. 'click'' harder gear,..
Try it and see...
Just dump the big ring/change chainrings and voila, 2x10!
Good point in favour of 3x10 from Cy from Cotic here.
(...) I'm a long time triple chainring user. It seems somewhat unfashionable these days, but I've never run into trouble with wrecking outer chainrings, so a bashring hasn't really been necessary. When I've used double/bash set ups before I've either found them noisy and unreliable (32t largest chainring, constantly bouncing out of gear on the 11 or 12t sprockets at the back, noisy chain slapping on the chainstay despite being very tight for the setup), or I've not at all got on with the big jump between front ratios (on a 22/38 where I found it very hard to deal with the big gap when dropping from 38 to 22). So, I've always come back to a triple, usually 22/32/42. It suits my spinny pedalling style, and I HATE pushing my bike up anything, I like the challenge of a techy climb, and sometimes (whisper it) I'm so tired from a long ride I can't push a gear any bigger than that, so 22/34 is lovely thanks.At the other end, as soon as the trail points downwards, I like running in the big ring/middle of the cassette which keeps the chain nice and tight and quiet and out of the way of the frame. I prefer this. On my hardtail I can push an even bigger gear really slowly to help calm the bike down over rocky sections (it's one of the keys to going quick on a hardtail in my experience), and on a full sus you get much less pedal kickback effects in the big ring so your suspension actually works better. It's a minor thing, but doing what I do, I like knowing that.
In between I like small jumps between chainrings which make managing gears on climbs easier, and whilst lots of gears means lots of duplication, it also means much closer ratios by-and-large, and I like that too.
and also worthwhile mentioning in this context
However, I'm not trying to win you over to my way of thinking at all. Most of the guys I ride with use double/bash. Yet another group I know have a lot of singlespeeders. My point is that I don't go around pointing and sneering at them for their drivetrain choices, and neither should anyone else sneer at mine.
happy with it on my 26" hardtail - saw no reason to change...but will the bigger wheels make it relatively harder to pedal for the same gear? or not noticable?...off to pedal up some alps and used the 22x34 a lot ...
29er feels about 2t harder. E.g. I run 32:18ss where I'd run 32:16 on small wheels.
22x34 is really low, 22x32 equivilent is fine.
In summary, run what you brung and MTFU.
