I run a 110bcd CinQo on my MTB but you are limited to a 34T small ring (33T if you can find one). So on my XC bike it is 1:1 in the lowest gear. I have one on my singlespeed, which works out fine because 34T is pretty standard up front. We are looking at MTB cranks, but we will need to support 4 bolt systems and a smaller inner ring. Any product is at least one year away.

I run 46-34 up front and 11-34 in back. The 46 is plenty big for MTB, usually people have a 42 or 44. Overall the gearing is a bit tall for general use, but not too bad. It is certainly fine if you ride in rolling or flatter terrain (Texas, Minnesota, Wisconsin, etc.) It is also fine for racing, the low gear is 1:1 so when that is not enough, you are not worse off to just push / run.

If you CinQo is a year old, you are welcome to it back and we will give it the check up for free. Email us at thinkfast@quarq.us to arrange.

I currently have a Deore LX FD from around '04 or '06. The main thing is to make sure it can get positioned vertically correctly and not have the inner plate contact the 34T ring.

Yes, the Rotor 3D 110 bcd CinQo will fit the Rotor 3D MTB cranks. However, there is no 74bcd inner ring.

Jim

Lan,

We only have one 110bcd Rotor CinQo. It is primarily for road use, but works nicely on a mountain bike. You can run one or two 110 bcd rings on it, but there is no mounting point at all for a 74bcd ring. So you will have power measurement in both rings, but the chainring sizes are limited. I use 46/34T on mine.

"We only have one 110bcd Rotor CinQo. It is primarily for road use, but works nicely on a mountain bike."

Does this comment mean the 110bcd Rotor CinQo is available for Rotor 3D or is in reference to the old Agilis one?

I would buy a Quarq if it was mtb-specific. My preference would be one with XX chainrings.

I already have a PowerTap, but it is built into a wheel. Not only do I have multiple mountain bikes, but they have different wheel sizes.

I'll reiterate: I WILL BUY A QUARQ WHEN A MTB-SPECIFIC VERSION IS OFFERED.

Now, get to work!

XX CinQo. Gotcha. 10-4 good buddy.

don't forget about Shimano XTR 2X

+1 regarding the wish to see a MTB XX CinQo. I love my road Cinqo, and will be first in line when you offer a Specialized XX set-up.

For what it's worth, SRM is offering both a Cannondale 2x10 set-up, and an FSA 2x10 set-up.

Hey! I just noticed the Cinqos on the SRAM XO and on C'dale XX, that you posted on twitter...

Any news you want to share? I don't see anything for sale; are these prototypes, are "ready for prime-time"?

Awesome. I would love to see a CinQo XX on my Top Fuel.

Jim,

Are you using the Rotor 3D road crank arms and spindle on your mtb?

We have plenty of testers. We just need to get more machine time in between the road CinQos...

We're still shooting for a late spring release.

The first units will likely be for SRAM XO and Cannondale Hollowgram cranks.

I could test the crap out of one of those in the Lumberjack 100 in a couple of weeks....

Are the SRAM X0 cranks still on the agenda? Any news?

Just to add to that... There's no technical hold up. They're currently in testing. --Troy@Quarq

Troy, any update on the MTB cranks?

Troy, any plans to offer a 172.5 mtb crankset ? I set my MTB bike up as close as I could to my road bikes, including xtr 172.5 crankset. Thanks for your response. Keith

Thanks Troy! I am ordering my wheels. It will be nice to drop the weight of the Power Tap hub.

just came across this thread and was very excited. i've been a long-time quarq user on my road bike. i just recently made the switch to 2x10 cranks (and settled on the sram xx system)....and while riding an endurance race i recalled a teaser pic jim had posted a long time ago of a sram 2x10 setup that was being researched.

i've been amazed at how quickly the xx setup shifts in the front (lightning fast....seriously as fast as my road bikes); i even tried the xtr 2x10, and while it is great, it didn't shift as fast as xtr.

based on what i see from SRM, i'm guessing that the quarq may be based on the x0 crankset, not xx.

one reason i selected the xx crankset was that it came in a 156Q version, and i found that it works better for me to have the cranks as narrow as possible to get as close as i can to my road setup.

if/when the quarq product is offered, will it be available in a 156Q version? i have to temper my excitement a bit as it looks like the x0 is not offered in a narrow-Q version (the only spec i've been able to find is for the SRM x0 crankset, with Q of 168.5mm.

i appreciate any info you are at liberty to provide. i'm going to guess no to the xx and no to the 156 q.

thanks!

So now that the Quattro was released at Eurobike, what is the actual release/order/purchase date (incl. QBP)? The articles on bikerumor, cyclingnews, etc didn't mention. Thanks.

Seriously! What is the hold-up? When will this be released for sale? Will it be open for European orders?

Thanks, Johan in Sweden...

We announced the Quatro MTB power meter at Eurobike. Originally we anticipated shipping them in November but now we expect to ship them in October. At this stage they will be SRAM 2x10 only with an X0-level carbon crank arm and 39/26 X-Glide chainrings. The Quatro will be available worldwide from SRAM's distributors and dealers. We will not be retrofitting spiders to existing cranks and are not yet making Specialized and Cannondale versions. I'll get back to you on Qs. --Troy@Quarq
