110 BCD elliptical 2

Elliptical chainrings have come and gone, but lately they seem to be gaining a lot of traction. Not only has the technology improved to create better profiles, but the advance of 1x drivetrains leaves fewer limitations to the chainring design.

In the case of Wolf Tooth Components, their newest elliptical rings are a direct result of consumer demand. After releasing their 110 BCD Shimano elliptical rings, apparently the demand was so loud for rings geared towards road, CX, and gravel that WTC moved up the production to be able to ship in 6 weeks. That was 6 weeks ago, and the new elliptical rings are ready for your bike…

110 BCD elliptical 1

Machined with a 110 symmetrical BCD, the new rings will be right at home on many road/CX cranksets. Each ring is designed to be used in either the inner or outer position on the spider depending on the chainline situation. As always, each ring is machined in Minneapolis out of 7075-T6 aluminum with WTC’s patent-pending Drop Stop tooth profile.

110 BCD elliptical 3

Available in 38, 40, and 42t rings, each Elliptical 110 5-Bolt Drop Stop ring will sell for $78.95. WTC also snuck in a little teaser saying 2 new lines of elliptical rings are on the way!

2 lines? Hoping for a double setup

I don’t see anyone making directmount sram cx rings? Are they just too big to keep stiff with the center attachment? Cannondale’s SI direct mount seems to get pretty high marks for stiffness.

40T and 42T should be 130 bcd

I do not think a direct mount would be a problem. It would be close to 200g I would assume. I currently have a direct mount carbon on an older set of cranks and it is 109g and there is zero flex.

Garbaruk has some Sram Direct Mount chainrings up to 42T I believe. Maybe even larger.

I honestly do not understand direct mount for “large” road/cx/gravel chain rings. Why would one not want to take advantage of tying into the crank arm…maybe fears the crank arm is not stiff and actually induces flex into the chainring? (which for the most part is only tangentially loaded sans frame flex and chainline)

We already do Sram CX1 direct mount rings for some time in 36, 38, 40 and soon 42 and up to 50T. Same with 110/4 and 110/5bcd

If the crank has integrated spider with arms, ie. one piece design like Shimano road cranks, then such solution is a little bit stiffer than direct mount.

But in case of Cranks with removable spider like most Sram Cranks including CX1, attached spider to the crank arm and then chainring to the spider is not stiffer than one piece direct mount ring if made correctly.
Such removable spider is essentialy a part direct mount chainring in a sense if you know what I mean. More over such spiders are usually cast from softer aluminium. So to keep certain stiffness they are quite bulky and heavy.

One piece design like direct mount rings is best possible solution for cranks with removable spider. Such solution is lighter, looks better, uses less bolts and is as stiff as spider+ring combination if not stiffer in some crank cases. You can also use every possible size as you are not locked to BCD diameter.

hope that helps

Thanks Marcin – now I just need to get you guys to sell me a 64BCD 30t oval ring. Love my 28t AB oval. Although I won’t buy it for about 6 months…winter/holiday fat gain mode has really put a damper on my ability to push a 30t

JBikes – For me, personally, it’s about

1 – replacing a boat anchor rival spider (not the same as force/red models, not even swappable actually – different shape)
2 – looks. I admit it. I think DM chainrings in 1x setups look bad ass. I like my bike to look bad ass.

Alas, still no stainless SRAM direct mount in a 32 tooth.

There is good reason to use bolt on versus direct mount for larger sizes.

First – The spider, although heavier, is also stiffer because of its deeper forged design (even if mounted in a direct mount style). Most spiders are forged not cast and there is no loss in stiffness between these “softer” materials and the 70XX used in rings. In fact, some 20XX spiders are actually stiffer for a given geometry.

Second – The replacement cost of a flat ring is significantly cheaper than replacing a direct mount.

will these work with SRAMs hidden bolt cranks? ive been looking for an elliptical chainring for my QUARQ Red crankset but all the options I’ve found say it doesnt work with the hidden bolt cranks. i hope this one does!

@ saddlesore
It will not fit Sram cranks with hidden bolt. Reason is timing of the ring. You can actually mount WT or AB rings on those cranks with no problem but timing of the oval will be in wrong spot. So this is why we say it will not fit.

But I see WT does not have such information to warn customers on their website about this and if you use it that way you will be really not happy. You would get Biopace timing…So I am guessing they forgot to put that information or simply not realized that as they try to catch up with ovals too quickly 🙂

For Sram cranks we do Direct mount oval CX chainrings, but it will not suit your power meter then.
