Just got my bike back from my mechanic and he was not able to get the two to work together. Currently running 50/34 Rotor Q-rings, old Ti red FD, and 11/28 red rear cassette on a Litespeed C1. I was having issues shifting from small to big chainring, so I purchased the new yaw FD thinking this would solve the problem but I couldn't have been more wrong! Not only was it having the same problems shifting, but the chain rub in both the lowest and heist gears was out of control. Pretty sure the the yaw is supposed to eliminate that completely? Could this be an issue with the frame flexing at the bottom bracket?

So, is it my mechanic or my grouping? Is anyone running Q-rings with the new SRAM FD?

Thanks!

1. Sram doesn't have the best front shifting but we know this, before the Q-rings how was the shifting ?
When I first tried Q-rings I was using sram apex with 52-36 aero rings on a sl2 roubaix, worked pretty good. I switched to a force FD and it worked better. Now I have di2 and it shifts perfect, every single time.

2. I don't think its the frame flexing unless you are shifting under a heavy load every single time, my guess is find another mechanic.

have you shifted the 2013 yaw FD?

Im not sure the skill level of your mechanic but there is no reason why this shouldn't work. I have an almost exact set up:
BMC SLR01
Sram Force shifters (used the set up with the 1st gen force and the new gen force shifters with great results)
New Sram Red YAW FD
Sram Force BB30 crank with 53/39 Rotor Q Rings.
11-28 Ultegra cassete
I'm no mechanic and never worked at a LBS but my shifting in the front is flawless with no chain rub at all. I simply followed the install instructions on the sram site. You do have to be very precise when setting up the height and angle of the FD. This will make all the difference. Make sure your cable is nice and tight as well. Many mechanics, including the one who sold me the FD said it wouldn't work because Sram said so but it's simply not true. Many tests were done showing otherwise.

+1 on finding another mechanic. Setting up FD's for non-round rings is not your typical tune up or cable replacement. I have not delt with the Q rings, but spent a couple hours dialing in my FD with Osymetric front rings (which are much more "unround"). It ultimately required some filing on the FD and bracket; that's not something I'd put in the hands of the typical LBS tech.

The OP is referring to old red FD. His mechanic couldn't adjust the new red FD. To awnser your question yes but it was on a full group, don't know how it would perform using just the new FD. I know many people have just switched the FD and say it shifts great but I believe part of the problem with sram's front shifting is in the weak rings they use.

The main attribute of the YAW FD is it's much stiffer, both the linkage and the cage. YAW only serves to eliminate chain rub when cross chained. The improved stiffness makes it much more forgiving of imperfect shifting technique, which we are all guilty of when tired and/or under stress, than the old flexible Ti Red FD. How does the extra stiffness play with oval rings? I dunno.

YAW FD with the Sram Red Quarq on my CAAD 9 runs perfectly. Maybe you need a new mechanic, maybe not, but he yaw FD can be tricky to adjust, but once it's done correctly you should shift with zero loss and no rub even if cross chaining.

Thanks for all the replies, I was afraid (yet relieved) that the answer seems to be to get a second opinion. I'll be in touch!

I'm in the military stationed in Germany, and turns out finding a good mechanic is harder than I thought...

Turns out it was easier than I thought. I youtube'd instructions and sure enough I was able to install and adjust it relatively quickly. Huge relief!

So to answer my question, you absolutely can run SRAM's new Yaw FD with Q-Rings. No chain rub, spot on shifting, love it! Unfortunately right now this is all on the stand, we got 4" of snow last night and it hasn't stopped yet so I'll have to wait a few days before I get back out on the road. Thanks for everyone's help and input!

Awesome job! Youtube instructions is what I used as well and had 0 problems. Just make sure you have proper cable tension on there As much as I'm for supporting your LBS, this is one of those times when it good to know how to do some of your own wrenching
