I'm not a small guy and run a 1x11 setup, after going to a 1x setup I've never looked back, I've not had a chain jump off the chainring, no annoying rubbing of the chain on the front derailleur, no shifting problems.  I believe that a 1x setup will work for most people if you choose your chainring according to the trails you ride in your area.  Admittedly SRAM's 1x11 setup was originally designed for racing, and because of that, they designed the front chainring to be changed out easily without the need to remove the cranks.  I've ridden lots of trails, and all the standard setups, 3x9, 3x10, 2x10, 1x9 and now 1x11.  By far my favorite setup has been 1x11.  It gives me enough range, very fast shifts, and a level of reliability I have never known until now.

Happy to see you got your issues sorted out with the front derailleur, I would not have guessed that changing the chain would have fixed the problem.  Reading your post initially I thought you did not have enough throw on the front derailleur, bad chain line, or a bad chainring but you have proved the problem was with the chain.  Understanding why moving to a Shimano chain fixed the problem would be interesting to know.

Honestly I can follow you regarding the 1x11 setup but I need a 42 back and a no bigger than 27 in the front to climb the long steep sandy hills around here and at the same time racing some fast Enduro sections with 30+ km/h - I cannot see how I could manage that without some crazy 120+ on the pedals :D

Regarding the chain issues, the chainrings are brand new same as the chain and the testing was done with the chain in a straight line in order to eliminate chainline issues. To be honest I did not even consider the chain itself but that was the only part that I had a spare one and it turned out to be a good idea, not too impressed with the SRAM combo to be honest.... I hope that XX will be better than X9 or I will change for a XTR setup.

Unless you are doing the long steep sandy climbs and the fast enduro sections on the same ride, the 1x11 would still work, however, if that's the trails you have, I agree that you are one of the few that need a huge range of gearing.  What drew me to a 1X setup is how much overlap there is on multi-chaingring setups.  I had already moved from a 3x9 to a 1x9 setup and while it was more difficult to climb hills, it was doable and made me a better rider.  I'm not quite a single speed guy but I can appreciate the simplicity.

On my ride last we had a guy running a 2x10 X9 setup and was having nothing but drivetrain issues.  Next time I see him, I might mention to him to try replacing the SRAM chain with a Shimano XT chain.

@Carbon_Dude:
what trails are you riding? I never rode 1x11 and I really should. But I doubt that I would be happy with 1x. (I'm rather light compared to size.)
Firstly, the range for the marathons I ride would probably not sufficient. If I chose a gear to climb 3000ft with steep sections I would not be able to keep up on the long descents.
Secondly, the gear jumps would be too big on sections with little speed change.

Still I need to try a 1x11 to see if my theory is correct.

Not saying a 1x11 setup works for everyone, but many of the pros have switched to it.  Here is one of my favorite trails that's just 15 min from where I live.



This trail has a decent amount of elevation change, some good long climbs, and some fast sections with max speeds around 22-24mph.  I think it's a great all around trail and it works well with my 1x11 (32T, 10-42) drivetrain.

Unfortunately you are correct, the local terrain here is a good combination of quite flat terrain with some very steep climbs up to 25%. As Denmark is very flat we do not have long climbs like you guys have but we still have trails that can keep my average pulse at 160+ and I'm 53 :D

Hi Karsten

How do you like your 036 frame?
I'm looking at the same frame and will be buying one soon too from Peter.

Ps. Where in DK are you riding?

Best regards

Hello Kim

I'm located in the northern most part of Denmark(Jutland) and mainly riding in that area - I have yet to take the bike for a test ride as the weather have been really bad the last few days with snow, hail and rain. I don't want my first ride to be too muddy/wet.

I will give a good feedback here when I have something to share

I finally got around to take the 036 for the first testride yesterday, weather here in Scandinavia have been terrible and I was awaiting the last bits and pieces for my XX groupset. Anyway, it became a very short testride as my MTB shoes are hitting the seat stay :( My crankset is a Truativ XX 2 x 10 with a 166 wide Q-factor and my pedals are the CB Candy. I'm hitting quite hard especially on the right side and I have to force my shoes out in the cleats, making it very hard for my worn knees after even a very short ride. Do any of you have the same issues on the 036 frame ?

I'm now looking into longer spindles for my Candy's and apparently I can find a ultra long kit on eBay, problem is that I can only find them in Titanium and I'm afraid that I'm too heavy for Titanium - Any suggestions ?

I've had no problems with my shoes hitting my seat stays on my -036, I am not sure how much clearance I have but I don't think I've ever brushed the frame with my shoes.

I assume you mean that you have a Q-factor of 168mm not 156mm, that would make a difference.  Also, when I installed my SRAM GXP bottom bracket on my BSA threaded BB -036, I needed to add the included 2.5mm spacers to either side to compensate for the 68mm wide frame and move it out to 73mm.

You might be able to get a few millimeters of clearance just by adding a washer to your pedal spindle.  Of course you want to still have a minimum thread engagement equal to the diameter of the shaft.

You may also pick up a millimeter or two by adjusting your cleats, or by changing to a different brand of clipless pedals.

On the SRAM/Truativ XX 2  x 10 speed GXP crankset the Q-factor is either 156 or 166 mm. On my set its stamped 166 mm at the sides of each arm. I have already tried with a small extra washer as well as mingling with the cleats but it is unfortunately not enough. I will need at least 5-7 mm more to stay clear. I either have the choice of finding a longer spindle for my Candy's or maybe another pedal system - However I love the Eggbeaters and would hate to change to another setup. Also, the "knee saver" adapter is a no-go as they move much too far out for my liking.

I went on a longer ride today and I definitely have to do something with regards to rubbing, I have just ordered those:

Hope they work for you.  How much extra clearance do the longer spindles provide?
