This is not about money. This is about chainring options and controlling chainline (50, 53, 55, 57 on and on)

the chain line can be easily changed with spacers or different offset chainring, wolftooh, garbaruk, hope, praxis all have T-Type compatible chainring, and probably others I don't know from top of my head. So you can pretty much do all you might want with a T-Type compatible chainring. You have options to run non transmission wide cranks 8 or 3 bolts, you can change the chain line with T-Type sram chainrings on wide spindle transmission cranks, as well as any other combination you might think.

There is really no reason not to use a T-Type chainring given there are plenty available.

 

Who has any experience with the new SRAM T-Type chain on any other chainring?
Is there a chainring you have working?
Does it work very well?
As you can see below, the new chainring teeth are .13mm narrower That means the T-type chain will rub on the old chainring teeth for a while until it wears thinner.

FYI:
2018-2022 SRAM Eagle Narrow-Wide Chainring Widths
Narrow - 1.93mm
Wide - 3.53mm

2023+ T-Type SRAM Narrow-Wide Chainring Widths
Narrow - 1.8mm
Wide - 3.4mm

Interesting. I wasn't aware that the widths had changed. It sure seems significant. If/when I change over, I expect I'll go for compatibility.

 

Thanks. Those are all good options but...
What I'm looking for is examples of people using non-T-type chainrings. I'm looking for people using rings other than T-type.

Changing the chainline more than 1mm via BottomBracket spindle shims is not an option in my book. I want my pedals equidistant from the center of the seat. Not off to one side or the other.

Furthermore, I am seeking a chainline that is dead-center in the middle of the cassette. This business of the 4th smallest cog being straight off the chainring is too inefficient when you are on the 2 biggest cogs. Manufacturers want the chainline out to give the chain clearance from the rear tire as it spans across, however, I can't find any 2.6" tires I like or any tires that rub the chain. I am looking for the chainline to be in the center of the cassette. Not in. Not out. Center. You would be surprised but that's asking a lot.

Yes. There are options for T-Type but in the grand-scheme, those are rare compared to the 10 million mountain bikes on the trails at this time. I'm looking for standard 104 BCD (bolt center diameter) options available via Amazon or Ebay with names like DEKAS or Bynccea or YBEKI or MSRECK or BUCKLOS or Dyomece or whatever crazy name you can think of. They cost peanuts and can be had in days.

Wolftooth and Garbaruk and Hope and Praxis all want 100 bux, give or take. When you have a lot of bikes, you look for standard parts that don't break the bank. When you are a bike shop and you service hundreds of bikes, you look for parts that don't turn the customer away.

Rest assured, a bike shop isn't going to stock 1,000+ rings when you consider tooth count, chain-line (offset), bolt-patterns, direct mount types, oval or not, oval %, color, material, tooth shape and tooth width. I'm sure I forgot one but you get the point.

 

What you are asking really doesn't make any practical sense. If you can empty your wallet for t-type, then why spend any time trying to find a cheap non-t-type chainring that works? Just get one designed for t-type. Its like buying a Ferrari and then saying you want to find the cheapest possible oil to run in it, even though the manual says to use expensive synthetic oil.

 

Exactly. You understand but don't agree. That's Ok.
I want to use all my S-Works carbon and aluminum XTR cranks with 104bcd now that threaded BSA shells are back. I could spend a lot but I don't need to.

 

The pin to pin length on T-type chains is the same as previous Eagle or Shimano chains but the rollers are larger. This means the pitch is functionally smaller than a previous Eagle or Shimano chain.
This has potential to skip on non T-type chainrings because the teeth don't line up with the rollers. This is potentially dangerous.

I agree. I'm aware. The rollers are larger on T-type chains but maybe that doesn't matter.

Riding any bike is dangerous. I've considered that.

 

Wolf Tooth makes a Drop Stop B and 5Dev makes a $200 Ti chainring. Both work with the T Type chain.

 

I'm sure someone will make a platinum chainring for $1,000. I'm aware. I'm looking for people who have tried non-T-type rings with T-type chains.
I'll eventually buy T-type stuff and try it myself but it could be years down the road. I'm trying to know now via a forum. Someone knows....

 

I think what I'm finding here is that no one has tried it. It's just a matter of time.

I expect that's right!
Your first three questions were much to explicit and simple to get a simple answer.

 

I've got over 1k miles on a Garbaruk Eagle chainring on my mine (regular bike) w/ no issues (they have since updated their rings to be T-Type compatible; mine predates that running change).
Cam Mcrae over at NSMB also used an Eagle ring on his ebike w/ no issues .

Nice!
SRAM Eagle 12 speed 2018-2023 Chainring works. Logged.
Thank you sir!

 

The next question is if someone has tried one of these? The DECKAS for 12 bux on Amazon. Sure. You can spend $500 on some new T-type cranks but if you have 104bcd cranks, spend 12 bux. If the ring wears out, spend 12 bux again. You get the point.

I've had 100+ mountain bikes in the last 35 years. I know T-type won't be the last drivetrain so I'm treating it as just another standard. In order to have 100 more bikes, I have to think twice when they want $650 for a derailleur. Heck, Wal-mart has a whole 29er aluminum hardtail for $350. I bet it sucks but that puts this in perspective.

 

It's only $12 bucks, buy it, ride it and report back.

Yah but $1,000 for some T-type parts as winter approaches. Not happening. That's why I posted here.

 

Out of this whole (stupidly overpriced) system, the chainring is what you're worried about? Best go back to Microshift.

 

That doesn't help.

BTW, Microshift has a new Advent X Version 2 derailleur that is supposed to come out this year. It's delayed due to some production problem.

 

[Nevermind...better thread for this elsewhere.]

 

Bump

 

This one does not work with T-Type chain

 

Good to know. What does it do that's bad?

Just purchased the one up switch (0mm offset) and their 12 speed chainring that claims to t-type compatible. will report back and see how this works.

 

Have you tried yet?
I'm desperately looking for 0mm offset oval chainring compatible with T-type chain for SRAM's 3bolt system, and aside from Wolf Tooth (that's out of stock until january), I couldn't find anything.

 

A chainring that DOES NOT WORK with SRAM T Type flat top chain is the Absolute Black 104 BCD premium narrow wide round chainring.

It says in the description that it is NOT compatible and it really isn’t. The T Type flat top chain barely fits on the teeth it’s so tight and if you tried riding with it the chain would jam and ride up off the chainring teeth throwing the chain.

absoluteBLACK | Round 104 / 64BCD 1X chainrings

I had one spare lying around and thought I might be able to use it but it’s nowhere near working.

Absolute Black do make some compatible chainrings but not in 104 BCD sizes just yet.

The chainring I’m actually using is a Wolftooth Dropstop B 104 BCD chainring which is fine with no issues.

The Pass Quest above is the same way.

 

I contacted OneUp and this is what they told me:

Great question!
All of our chainrings were designed around X-Sync2, rather than T-Type chains.
So far our experience with the combo has been in line with that of a reviewer from NSMB -

"SRAM X-Sync rings will work relatively well. I know this because I have been using one since the T-Type version wasn't available for the eMTB application on the Trek Fuel EX-E I've been testing
(which was the only UDH bike I had at my disposal to test the T-Type system).

Apparently, the long-term durability of the chain and cassette won't be as impressive without the new chain ring, and chain retention may be compromised as well, but for me thus far, it has been flawless."
So while we don't have an officially compatible ring, they will work happily with the Transmission drivetrains.


My takeaway from that is no way I'm doing it with the price tag of X0 cassette and T-type chains.
I'll rather keep riding the stock GX cranks until WolfTooth stocks the chainring I want again in january.

 

Thanks guys!
