wesley_r Posted April 7, 2012 Share I've been toying with the idea of changing the drivetrain on my Commencal Meta 5.5 from 3x9 to 1x10. Well, that's not entirely accurate - currently I've got a bash guard on insted of a big ring, so technically it's 2x9. Am I right in assuming that for the front, I can simply remove the little ring, run a 32 and add a chain guide? For the rear, I need a new casette, derailler and shifter, right? And of course a new chain. Silly question perhaps, but do I need a new rear hub? Anything else I'd need? Link to comment Share on other sites More sharing options...
Pronutro Posted April 7, 2012 Share Sounds about right on all accounts. And no, you shouldn't need a new rear hub. I am not the most technically proficient guy around here though. You are bound to get some good advice from others ... perhaps after the long weekend Edited April 7, 2012 by Pronutro Link to comment Share on other sites More sharing options...
Captain Fastbastard Mayhem Posted April 7, 2012 Share I've just done the conversion to 1x9 on my hardtail. All I need is a bash guard and a chain guide. Very easy to do. BTW: why go to 10sp? You won't need a new hub, but u will need a new rd, shifter and cassette. Link to comment Share on other sites More sharing options...
NotSoBigBen Posted April 7, 2012 Share I would also ask why 1*10 and not 1*9? Perhaps the better ratios on 10speed cassettes? Link to comment Share on other sites More sharing options...
wesley_r Posted April 7, 2012 Share cpt - 1x9 is definitely the way cheaper option - all I need is a chainguide. So I may indeed do that for now. But 1x10 will give me that 1 extra gear on the back for climbing (at least that's the theory). Climbing on a 15.4kg trail rig is not fun on the middle ring Edited April 7, 2012 by the_wes 34clint 1 Link to comment Share on other sites More sharing options...

Climbing on a 15.4kg trail rig is not fun on the middle ring Granny gear and smallest one will be the same. It's just an extra gear shoved into the middle somewhere! I'd keep it 1x9 dude. Just maybe change the cassette if you currently have an 11-34. Slap an 11-36 on there. Edited April 7, 2012 by cptmayhem Link to comment Share on other sites More sharing options...

Just maybe change the cassette if you currently have an 11-34. Slap an 11-36 on there. Agree, I would keep the 1x9. 1x10 won't make a difference on the climbing gear. Of course, if you wanted an extra gear in the middle somewhere, to have a better spread, then 1x10 is the way to go. But you can always do that later. Either put a bigger cassette on, or go smaller in the front if you are going to climb a bit. Link to comment Share on other sites More sharing options...
wesley_r Posted April 7, 2012 Share Thanks for the advice - I hadn't thought of it that way... 1x9 IS the WAY cheaper option - all I need is a chainguide. Link to comment Share on other sites More sharing options...
wesley_r Posted April 7, 2012 Share having said that, it doesn't seem like 11-36 cassettes are readily available? Link to comment Share on other sites More sharing options...
eddy Posted April 7, 2012 Share Do the sums and figure out what that one extra gear wil cost you. New RD, Cassette, chain........ That can add up to a fair whack and the marginal benefit is tiny. Spend it elsewhere and stay on 9 speed, IMHO . Link to comment Share on other sites More sharing options...
Flowta Posted April 7, 2012 Share having said that, it doesn't seem like 11-36 cassettes are readily available? I have a 9 speed 12-36 if you're interested Link to comment Share on other sites More sharing options...
(Deon) Posted April 7, 2012 Share I'm about to make the 2 x9 change. What made you want to go down to 1? Edited April 7, 2012 by Pain or Shine Link to comment Share on other sites More sharing options...
wesley_r Posted April 8, 2012 Share I'm about to make the 2 x9 change. What made you want to go down to 1? I don't actually know what my reason is. I think I'm just full of crap I am curious as to whether there'll be a significant weight saving, plus the thought of having 1 less derailler and 1 less cable that need maintenance and can give hassles (as my FR currently is) would be nice. And I would like the security of a chain guide - having said I can always get a tensioner / roller to run with my current 2 ring setup It's also the fact that I literally use 1 or 2 gears on the granny ring. Seems like a waste By the way eddy I may be building up a 2nd bike - my old Mongoose Tyax hardtail - for puttering around with the family. So at some point I need to start collecting components for that, may as well upgrade my Commencal and "hand me down" the old drivetrain Link to comment Share on other sites More sharing options...
