Xtr chain ring

andrewyzfr6

Hi,
I have 2012 xtr crankset (running 2x10 with 28t and38t) on my orange 5. I think it's m985 trail? Any way I've just changed my 2009 18" frame for a 2012 17" frame. And I've been told I can't run more than a 32t outer ring. So I need to get a 32t ring, problem is I can't find anywhere in the uk that has one. Any he please?

nicklouse

ERR WTF?

what frame?

Dirtydog11

edit: where's the delete?

Just posted a load crap didn't read the OP properly.

What Nick said plus a triple converted to 2X10 will work with a least a 36t outer.

Should of bought an M980.

nicklouse

or convert a 3 ring crankset. to use the two outer rings.

a 2 ring crank with the same chainline as a three ring crankset will be closer to the frame.

It's the pivot on a 5 though innit, gets in the way? Narrower q-factor and chainline on the M985s.

You won't get a 32t M985 outer, new chainset may be more sensible, or a less daft frame.

I'm pretty sure, though I maybe wrong that the Xtr 2x10 trail crank is the same as the triple but with different rings so the chainline is the same. Also pretty sure I've seen plenty of newer fives with this kind of double setup, whether it be sram or shimano.

Who told you it couldn't take that big a chainring?

I agree with Njee, buy a less stupid, overly-priced, over-rated frame.

The Five SE is fitted with the FC-M980 and 42-32-24 ring combination. This provides ample frame clearance and the broadest shift combination for all-mountain and trail applications.

The 38/26 version of the FC-M980 is NOT compatible with the Five frame, neither is the FC-M985 range, all having ring clearance issues with the main pivot.

I'd take it with a pinch of salt as I'm running a triple XT 770 10 speed with 24 /36t and bash, the chainline is the same as an FC M980 (50mm) so I see no reason why an FC M980 would'nt work with a 24 - 36t and bash.

Try your M985 and see!

Just remember to check pivot clearance whilst shifting up and down the rings

Humph. I bought the five frame as my old one did 3 years of abuse with no problem ( everything from the new forest to downhill at fort William and innerleithan) and never gave me any problems. I've seen other bikes crack and bearings go out of the pivots etc. In my experience people who haven't used a 5 are jealous as they can't afford or bought a different bike and just slag them off as they think their bike is better, but that is not the question I asked.
I have checked and my cranks are m980(sorry!) with a 26 and 38t. The guy at the orange dealer told me I couldn't run bigger than a 32t on the outer ring. And yes the cranks are the same as a triple set up. Any further help with where to buy - 32t xtr 10speed ring for this?thanks for the sensible, helpful answers btw!

Didn't know that!! Seems very shortsighted that a lot people would like to run such a gear ratio. Have orange changed the frame for 2012 over the 2011, I'm sure I've seen MBR running that exact chainset on the 5 with no issues? If you can't use it, well, its pretty much useless anyway...

He's wrong, you can run a least a 36t and possibly a 38t however I've not tried the latter !

They don't make a 32t for that chainset however the pcd is 104 so I would have thought any ramped 104 PCD 32t chainring would fit.

Something like

Although I wouldn't bet my life on it.

Singletrack fitted a 2×10 (24-38T) X0 groupset to Sims Longtermer 5 which is why I would try the 26/38 M980 before completely writing it off.

I've got the 38t outer on the bike now and the chain won't jump up to it as it jams on the swing arm. Orange dealer said that a 32 is the biggest that will fit on my outer( which is the same location as the middle ring on a triple chainset) I've tried finding a m980 32t middle ring but nowhere appears to have them in stock. Would buy a 34t or a 36t if I knew they would fit!

lawman

any old 32t ring will be fine, the trail double uses a standard 104mm bcd, so something like a TA specialites will work fine. Massive, massive cock up from orange though, why the hell design a bike that cannot be used with a now very common chainring setup...

You pay all that money for a piece of scaffolding and you can't even use a pretty common chainset :roll:

i would be tempted to get a tipple or add a spacer to the drive side and take it of the none drive. well you may get away with leaving it on the non drive side.

Dirtydog11

Other option would be to fit a 32t or 34t and go 1X10 although it wouldn't be my choice, we have hills round here.


If it where mine I'd sell it and get a triple with a 50mm chainline (XTR-M980 triple, XT- M770 triple or SLX triple) and you'll be able to run a least a 36t and a bash.

andrewyzfr6

'cos I use the bike all over the country on loads of different trails/hills/mountains I need to keep the 2x 10, it worked perfectly on the '09 18" five frame. I only bought the newer frame to accommodate a reverb(wider seat tube) and as the frame was a bit smaller if saves certain parts of my anatomy! An inch makes all the difference! I must see if I can phone orange to clear up the chainring issue, as if a 36t ring will fit I'd be delighted as my gear ratios will still suit me very well. Same problem applies: where to get a suitable 10speed 36t chainring?!

lawman

any 9 speed ring will work, I mentioned TA specialites before and they are very good chainrings and worked perfectly with 10 speed xt kit.

Dirtydog11

What Lawman said,

It's a 104 pcd so any make 104pcd ramped /pinned chainring should work.

Personally, I'm running a 9 speed 36t Shimano SLX ring, however my chainline is 50mm and not 46.8, it's the 46.8 chainline that's causing the clearance issue, if it where 50mm you wouldn't be having problems.

9 speed rings are fine on a 10 speed setup.

As I said earlier if it where mine I'd sell it and get a triple with a 50mm chainline (XTR-M980 triple, XT- M770 triple or SLX triple) and you'll be able to run a least a 36t and a bash.

You ain't going to get that double to work as double!

Here's my setup and proof you can run more than a 32T

Shimano M770 cranks (3X10) running XT24t/SLX36t rings with Gamut bash, Gamut ISCG P30 Dual guide and Shimano 2012 FD-M785-10 double specific mech.

I've ordered a 24t and32t chainrings, and I'll get a more compact cassette for the rear to solve the problem. I phoned orange, and the guy I spoke to said a 34t and36t will probably fit, but he couldn't guarantee it. He told me I should be experiencing the same problems with my old orange 5 but there is very slighty more clearance on the old 28mm seat tube and the hand welded rear swing arms all being very slightly different there could be variations on what works. So on closer inspection the welding is different so there is slightly more clearance on the old unit!

Bit late on picking this up but you might find this site useful for chainrings for your cranks (and others).

How will a different cassette help? You won't get smaller than an 11t on the cassette, so a closer ratio block just limits you at the bottom end. Stick with an 11-36, no point running 10 speed otherwise!
