Mike,

Your photo shows one hole off the standard 5-dot highracer setting. The bolt on the second spider arm CCW from the drive side crank arm is one hole off from the 5-dot hole. Technically speaking, this may be outside the range intended by Rotor. But what the hey, if it works, it works.

FYI: I aligned the 1-dot hole to the same bolt when I got my best results.

Said it before and I'll say it again. You don't need a photo with cranks in the dead spot. The key to setting up Q-rings on a highracer is aligning the appropriate dot with the second spider arm bolt counterclockwise from the drive side crankarm.

Keep on guessing, speculating, and posting. You can make it as complicated as you wish. Then try this method. It's the standard. (This method does not work on lower bottom bracket bents.)

That's the point...there is no "standard" and no "guessing" involved and the setup isn't off of any "standard". The instructions according to Rotor are:

While the cranks are held at your right LDS, place the large Q-Ring onto the spider and put the chain on the Q-Ring, so that the first tooth trough that fully engages the roller of the chain at the top of the Q-Ring (the side that pulls the chain) is directly above the Diamond frame regulation point #1.

The photo I've posted shows exactly this setup and, as mentioned, another individual may find that their personal setup is slightly different due to having a slightly different dead spot

The instructions provided aren't really as convoluted as some make them out to be in my opinion.

I agree, and I also believe we try to make it harder then it really is.
I certainly did at first.

My Q- Ring arrived late Thursday.
Just one (the large 53t ring).
Got it from the Hostel Shop.
Came with no instructions just in a plastic bag.
I guess if you buy a whole set you get instructions.

Set it up following posts to this thread.
Took it for a test ride and it felt a little Humpty Dumpty.

Rechecked this thread and read more carefully.
Did a readjust cause I missed a post or two.
A discusion back and forth about wich index point to use.
Readjusted, and it really smoothed out. Felt right thought it must be right.

Rechecked thread this morning and a couple more posts got me thinken.
The Creator has a manual, why not check the website of the creator of the Q-Rings
and read there manual.

After reading there instructions, I thought I understood there cryptic instructions.
As many have said you realy have to wrap your mind around there instructions.
Readjusted ring.
I now had it set to large side of ring ingaged at dead spot, small side on power stroke.

Printed out instructions from Rotor and reread this thread.
It was at that time I opened my box of cereal and got the decoder ring out.
Ureka, the instructions finaly made sence.

It comes down to correctly finding your #2 OCP spot, and a couple other details.
This won't mean anything to you if you havent read Rotors instructions.

As it turns out I was only one whole different than the one I had it set to before consulting Rotors manual.
Now as others have said their is a significant leway left to right from Rotors suggested sweet spot.
I am anal about getting it right so I wanted to be positive I was starting from creators suggested sweet spot.

Rotor says a higher ocp # is better for acceleration.
A lower # slightly higher top speed.
Also Mashers (earlyer resistance in stroke) lower ocp #
Knee savers (later resistance in stroke) higher ocp #

In my humble opinion the image of the Black Corsa setup in this thread is correct for a high racer + or - a whole or two.

It turns out my suggested sweet spot is only 1 whole different from Tweetys setup.
(plug for Tweety). If I only had listened to Tweety I could have saved some greif.
But I wouldn't know for sure.
Now I think I do.

This is my setup (do not assume it is your setup)

After only 30 miles my thoughts so far.

They seem to be a definit Knee Saver.
They relieve the force needed to stay at cadence when your knee is compressed.
Resistance gradualy increases as knee is extended.

It also feels like it will be a small performance boost.

I like them. They are pricey, thats why I opted for just one for now.

I just received my set of Q-rings Friday, and I'm still trying to get the crank arms off. Guess I'll have to find a hex socket because I can't get enough leverage from my standard set of allen wrenches.

I hoped I could remove the standard chainrings without removing the crank arms, but the inner ring will not clear the spider (unless magic is involved).

That hex bolt isn't glued is it??

The bolt you're refering to should have a minimal amount of torque on it (about 5Nm if memory serves) on the FSA Gossamer crankset . If you're having that much trouble it's likely the bolt is seized. Try laying the bike on it's side and applying some liquid wrench and allowing it to sit for a while.

it's definitely tighter than that...it's the SLK crankset on a new CA2...I'll try the liquid wrench

Are you sure it's a hex bolt? My chainring bolts required a star wrench. I got frustrated w/ hex wrenches not working and looked closely and said "doh".

It's definitely a hex bolt. I also have the installation brochure and it's shown as an M17 hex...

That is the way mine is set up and the bike came to me that way. I tried setting up the new 27 tooth ring with the high point in line w/ the larger 2, but I don't know if this is correct for easiest hill climbing.

My Ultegra has star bolts, but since I did not have one, I tried(just for grins) the largest allen which fit inside the star and it found an allen socket under the star.

I now have about 300 miles on my q-rings and I'm sold. Setup is crucial. Find your dead-spot, that's tye key.
My longest ride to date was yesterday. 68 miles with lots of rolling hills. I can definitely climb in a larger gear and my legs are not as fatigued at the end of a ride.. Take the extra time and set them up correctly.

I thought I would post a 5 month follow-up. Today I rode a fundraiser Metric century on Cape Cod. If anyone knows the Cape, the outer part has some pretty good hills out towards Provincetown. Now, I'm not a speedster and at 63 I never will be. But I averaged 16.5 (a person best) and was able to ride my 50 tooth outer ring the majority of the time. My legs are tired, but not cooked.
I guess I waited too long for the Q-rings. The best part is that I raised over $4000.00 for Hospice and Alzheimer's and had a real Cape Cod Clam bake to boot.

After reading much of this I went to http://searchallcraigs.com and found a triathlete in Florida selling Q-rings; I'll have mine by Saturday. Could have used them for Lookout Mountain (Golden, Colorado) this morning...
I'll share his contact info if you email me (paid $150 for 53/42 shipped).

Re: RE: Anyone not like Q-Rings? 2022/02/19 13:40:39 (permalink)
I haven`t tried a Q-ring yet, but I already have a 60 tooth big ring and a 10 tooth gear on the rear wheel for more speed, especially getting going downhill to get loose from the upright riders ( ie, until they catch me going back up the next hill, LOL!).  My chain had to be lengthened of course, and it takes meticulous adjustment of the derailer in order to be able to use all three chain rings....  `Don`t think the Q-ring would work for me.  My brute legs seem to be able to handle the current setup, although as I get older it becomes more difficult on the hills....
