Hi guys,

So it's finally time to post something interestingSmile

Many people are looking for spiderless rings but they are not cheap nor compatible with many cranks. So from last few months we have been working how to solve that. What we have came up with is lighter, cheaper and works great.

http://absoluteblack.cc/sram-spiderless.html

The ultimate solution for Sram cranks that feature a removable spider. Spiderless chainrings allow for flawless single speed or Sram 1x9/10/11 drivetrain setup. These chainrings save more than 150g over regular spider and chainring combo. Reliable, extremely light, stiff and clean looking on the bike.

For light riding chainkeeper may not be needed. For more aggressive riding chainkeeper will be needed. Tested by XC Silver World Champion Marek Konwa!

weights:
Absolute Black: 28t -44g, 30t -48g, 32t -51g, 34t -67g
this is basically the lightest solution on the Market.

Chainring tooths optimized for great chain retention while riding in rough terrain . In almost all cases chainkeeper is not necessary. Tooth profile is directional that means it will keep your chain on even when back pedaling on descent. Tested by XC Silver World Champion Marek Konwa http absoluteblack.cc sram-spiderless.html

only 5 links is enough to hold onto absoluteBLACK chainring!! Regular chainrings require at least double that.
This is to show how good retention this chainring has. It's all about the tooth shape which can keep the chain in place.
Try to do it with yours and see result.

Tehan, are you worried SRAM are going to patent the directional teeth you have used in their new X Sync patent?

It is certainly one of the features they will seek to patent in the XX1 ring as the Thick / Thin tooth profile was seen in a previous patent?

Surely once this wears a very small amount it will be just the same as a standard ring too? - That will happen pretty fast no?

I am not sure i will see a reply as this post is blatant spam so waiting to be deleted but i am interested, just sceptical - I would think the thick / thin aspect is key? Sram reportedly filmed many chains coming off and it was side to side movement causing it.

Hi Racer,
nothing better then a good beginning of the post.

Sram has patent for its own shape. I don't use their shape at all so don't need to worry about that. Such similar shape was used already 80 years ago so i can't patent it either. Same with thick-thin. what they can patent is exact shape of all the tooths and thicknesses- but that is design patent and i didn't copy it.

Thick-thin idea helps more but the key feature is the tooth shape as It will not wear much in a time.


hope that helps.

edit.
forgot to add a though about patenting.
You can only patent something if it was not public. Once it is public you can't fill the patent as an invention. I don't know US law that well but i guess it works that globally, not only in Europe. That's why when they invented postmount, or shimano their rotors, or anything elese - the patent was filled at least 2 years before launching it to the public.
The only thing they can and will patent is the exact shape, which i am not using.

Running an XTR clutch at the back and my new AbsoluteBlack 30t on my new hardtail. Lost the chain twice on my last ride. Trying a different chain in case the first was worn. Can't run the chain any tighter the mech would hit the rear granny

Sorry, missed that. I guess that you use long cage rear mech as that is usually the problem. Short one is usually best for single ring application aespecially that you use a small ring up front.

I got review lately from BikeRumor and they are extremely happy with that ring.

I know that for few folks it does not work (strangely only in UK) but i guess it's a mixture of mud and long cage.


I have also made xx1 style thick-thin tooth profiles for 104BCD and that cures completely the problem of long cage or a smaller ring and a bit of mud.

Will the absolute black sram spiderless chainring good enough for mega avalanche enduro riding? With only a upper guide?

Looking for something like xx1, 1 chainring and only a upper guide.
But then on my x0 type 2 derallieur.

cheers.

Just to refresh the news a bit.
We now offer our well known ring in narrow-wide version. That means ultralight and super secure chainrings. Its already proven tooth profile from our shimano rings is now in our Srma spideless ones!

Sizes from 28 up to 36T.
