MRP Bling or NSB chainring ???

[edle]

I need a 28T front chainring.
Which one should I buy and why ?

Thanks...

I have a Bling Ring. Although they are very similar, I think they have different chainline offsets. The Bling Ring is lighter and may (from reports on this Board) fit tighter on the spline interface of the crank arm. The NSB looks great though!

I've got one of each, but have not mounted the NSB ring yet - waiting to receive the crank it'll be going on.

As in the trees said, the NSB is a bit more inboard offset than the MRP - haven't measured just how much though. It does appear a bit chunkier/heavier, but I don't imagine it's that much.

Whichever is in stock and you can get a better deal on maybe?

If you have a GXP style XO or X9 crankset.. Take a look at the North Shore Billet chainrings.. I am using one with a Shimano XT Shadow + derailleur, 10 speed chain, and no chainguide...never measured the offset...but the chainline is straight when on the 5th cog in the rear..

Bling is lighter but NSB has more choices. NSB has 27T and Bling doesn't.
I look around and I can buy NSB cheaper because of less expensive shipping charge.

*Chainline: 47mm from the bottom bracket center according to NSB.

Thanks.....

This. Just put the NSB ring on the crank that showed up via UPS today. THe NSB was a touch less money.

It is indeed a *slightly* looser fit than the MRP ring, but I don't see it causing any problems, so long as you have the retaining bolts snugged up nice and tight,which you should in any case.

I'd still say go with whichever has the better chain-line for your particular setup, if it matters, then whichever has the ring size. Compromises here and there perhaps.

I'm happy that Wolftooth appears to be making XX1 clone rings to fit the SRAM spider AND the XTR 88mm BCD I have on my other cranks! Taller and retentive tooth profiles sound good. And they have it in the works to have a bash ring attachment for their SRAM spider rings. When that stuff is available, I'll be ordering up a couple!

any chance you could measure both rings offset? maybe from the outside mounting edge to the tooth center? i'm getting ~5.65mm on my 28t mrp but i'm curious how much difference there is with the nsb ring. i've had to get creative with bb spacers to get my mrp ring a decent chainline and centered with my e13 xcx so i'm wondering if the nsb would help.

From what I can tell, it's within 1-1.5mm difference. Not huge, but could be irritating in terms of setting things up without rub with various guide bits. Crappy pics, sorry. (in the middle of updating my garage electric bits - the light sucks)



Just finished swapping mine over - 175mm crank from the 170mm, same ring size, but NSB vs. MRP. Just to see.



Yep, that's an E.13 upper guide on an MRP backplate. May not work in all cases, but I found this works better than the stock MRP upper. Quieter, and gives better upper coverage. YMMV. But the rest of the guide (backplate and lower skid) works with the micro setup, since E.13 has nothing for this stuff...yet. They'd be idiots to not have something in the works, considering this single ring with odd/smaller ring sizes/needing some retention/bash protection market is growing. But I digress.



No spacers with the BB or "ring" and none with the guide back-plate. Works beautifully. Quiet, secure. I can swap the lower guide bits with my spare one which still has the roller for when hitting lift terrain, super easy, a couple minutes.

Have had a few rides like this (well, with the prior MRP ring) where I fully expected to drop the chain or screw up the shifting, but it didn't happen. The guide with clutch rear mech works great! I expect it to be even better with the upcoming XX1 clone rings, enough that I may not even need to run the lower guide ever.

Aside: Wolftooth site shows they will have XX1 clone rings for the XTR 88mm BCD! Woot! Taller, profiled, and single ring specific rings for those will rock, since I'm running them on two bikes...

thanks for the info! time to take some measurements...

also looking forward to how the works components ring and ring/bash/guide look once they are finalized.

We are indeed working on SRAM spline mount chainrings and optional bash ring. Very excited about this as I think it offers a pretty unique solution for those that want something really light weight & simple but still capable of taking some hits. The SRAM spline mount rings are getting really close and the bash rings not too far behind.
Curious what sizes (tooth counts) would be most useful?
And yes, working on 88 BCD also.

I'd be down for a 36t for both my 29er HT race bike and my Blur LTc enduro bike, too.

ABSOLUTE BLACK Kettenblatt Spider für Sram GXP Kurbel blau 51g, 54,50

available in 4 colours and few sizes. i think they will be soon available in US.

Best part is the weight:

MRP: 28t -53g, 30t -58g, 32t -72g, 34t -85g, & 36t -94g

Absolute Black: 28t -44g, 30t -48g, 32t -51g, 34t -67g, (36 in the works)

NSB: 28t -75g, 30t -85g, 32t-95g, 34t -105g, 36t -120g

they should be around 60$ in US.
XX1 tooths will follow soon on this chainring but it will be more expensive option as milling time is considerably longer.

Our rings are being tested right now on the trails and will be available anodized Black, Red, Blue, Brown, Gold, Purple, Green, Orange, Grey and Pink. We have about 6 designs that will be available including the ability to "design your own". Pictured is our 28T Cyclone Spiderless Chainwheel for Sram X0/X9 compatible splines.

I'll take a little extra weight at the ring if that means being able to run sans-bash and not have the thing fold over at the sight of a rock.

However, the Wolftooth option to run a bash seems pretty cool, especially if you don't want to run a BB or ISCG mounted setup, or can't due to press-fit BB or no mounts. Very looking forward to picking one up, and a couple rings for my XTR 88mm BCD cranks. No one else is making any for those, and having taller teeth/single ring specific/profiled teeth on those would be awesome, as they are both on top guide only setups.

I've had good luck with two upper guide/lower taco bash setups so far, but am not sold on the idea. Crank mounted bash, IMO, seems a better idea if one is prone to smacking things (hack riding moments, un-smooth trialsin moments, etc.)

First ride today on my NSB ring vs. the MRP that was on there before. Functionally, can't tell a damn bit of difference. Was quiet, had no dropping or slipping going on, and just plain worked. Go with whichever is in stock/fits your budget/ring size needs. The offset difference is pretty minimal, with the NSB being a bit more inboard, which may come in to play for some frame/crank/guide combinations.

Few photos from todays ride.
Yes it's UK and we have snow from yesterday... with mud. This is a custom brown color in case anyone wonders. This setup is with XX casette (12-36) and X0 rear mech and 32T on the front. I know i have a front mech still on... but chain retention is very good like it is on the photo, so i have not put any chainguide yet - as maybe i will not have to buy one. There is absolutely no problem with chain line in such setup. What i found is in most cases one rides in mid section of casette anyway for 60% of time, so chain is almost straight then.
