1x 11 Sram NX

Postby hjd10 » 4 Feb 2017, 7:33pm

Hi,

I've just upgraded to a 1x 11 on my MTB with the Sram NX system, as it fits straight onto a normal 9,10 speed wheel.
Early days yet although it changes nice and smooth, surprisingly the chain line issues with these systems don't seem as bad as I was expecting. Maybe this is due to it using a narrower 11 speed chain.
NX Cassette 11-42 - £60
NX Derailleur - £58
Sram Chain - £10
Chainset FSA Comet 32T - £45
NX Shifter - £19

Has anyone else tried the 1x 11 before?

The existing 10 speed XT/SLX that I took of this bike will be used on my touring bike.

Regards,

Does the NX Cassette really fit a 9,10 speed freehub? That is pretty unusual. I'm pretty sure that with SRAM you will normally need an 11 speed freehub for it to fit.

Yes the new PG-1130 cassette uses a standard 9/10/11 speed freehub. My wheels are Mavic Crossrides.
I guess the advantage is that it makes this group-set more suited to people who are upgrading and saves having to buy an XD driver that the other 11 speed Sram offerings require.

I have just put Rival 1x11 on my drop bar tourer, really impressed with the "double tap" shifting. PG1130 here too, no issues with chainline or fitting cassette etc.
Happy-happy.

you can read about it here;

http://www.mbr.co.uk/videos/bikes-and-equipment/sram-nx-the-new-1x11-groupset-for-250

SRAM say £250 all in; HJD's looks cheaper than that because

a) it is a different crankset(?) and
b) the shifter price is omitted for some reason.

Because the cassette is (like shimano XT 11s) 11-42 it will fit onto a standard 8/9/10s freehub body. The SRAM 11s cassettes which are 10-42 require a different freehub body.

You can do the same thing with shimano kit but it is (at present) more expensive, in places. The XT-8000 11-42 cassette is £54.99 at wiggle.

The reason MTB 11s cassettes can be made to fit 10s freehubs and road 11s cassettes don't (despite the same sprocket pitch) is all to do with spoke clearance for the rear mech. The MTB #1 sprocket can be set further leftwards than the road version, because it is larger and therefore further away from the (angled) spokes.

I can't help but think that with a compact double, you could have a nice set of touring gears with this cassette. Dunno how long it would all last though.

If you just want the gear range you can get 10s 11-42 instead.

11s goes 11-13-15-17-19-21-24-28-32-37-42
10s goes 11-13-15-18-21-24-28-32-36-42

so basically you get an 18T sprocket in place of 17 and 19T ones, and a 36T instead of a 37T.
cheers

Ooops yes forgot the shifter price, it was £19. I sorted mine for less than £200.

I've tried a Sram GX 1x11 and even if I do not like trigger shifters (the bike had that) it was ok.
Not sure if for me works better than a 2x10, but you don't get the FD clogged with mud. Also it saves you the rant of poor shifting and wear from Sram chainrings.
The NX is a bit on the heavy side, but it may be a good solution for the ones that want a "no brainer" and do not need a super wide range. After all, better legs are always in need more than gears :wink:
It is by riding a bicycle that you learn the contours of a country best,
since you have to sweat up the hills and coast down them.
Thus you remember them as they actually are...

Its definitely not the lightest setup. I've noticed however the groupset is on some bikes that are below £500 all the way up to +£2000.
Anyway I'll give my bike a test on Wednesday as I'm going up to Dalby Forest with a group from work. :wink:
Have to wait for the 12-speed Sram Eagle gearset to drop in price, the 10-50 cassette must near to or very close to the ideal touring range. :evil:
