Rotor Q-Rings Chainrings

4.09/5 (11 Reviews)
MSRP : $199.00

Product Description

Rotor Q-Rings help to minimize the time spent in the dead spot while pedaling. While oval chainrings have historically been controversial, we believe that allowing a rider to fine tune the chainring position offers opportunities to minimize the dead spot never before realized with conventional chainrings.

Strengths:    For several years now I have used Rotor Q Rings installed on different bikes since their introduction to the market. I liked the way it reduces the dead spot on the pedaling stroke and the ability to adjust the intensity by changing the regulation points.

Weaknesses:    Just recently however, I noticed pain and tightness on my left calf only, my right calf is not affected in any way. Wondering if because the Q rings keep you in the power strong longer this is placing more stress on my left calf muscle. I am going to change to #2 or #1 to see if it help relieve the pain in my left calf. Hopefully this is just individual physical thing and the aging process taking its course, and not related to the rings. Anybody else have this problem?

Bottom Line:   
Other than the above, I like the Q rings.

Strengths:    Better pedal stoke with decreased knee pain. Not sure about the climbing part yet, but I'm smoother and slightly faster on the flats....we'll see. Definitely something that's fun/interesting to try and seems to have some merit.

Weaknesses:    Shifting is slightly worse, but still good. Price isn't terrible either.

Bottom Line:   
These came on a recent purchase of a compact crankset. I'm using the Aero 52T outer ring and a 36T inner ring. I'm running these on a Look 595 Ultra with full Campy Record 11 speed setup (excluding cranks obviously). For comparison I have a Pinarello Prince with full SR11 setup (Campy 50/34t compact cranks with standard rings) as well.

I'm still testing, but after several long rides (60-80 miles) here is what I've noticed so far. 1) It took almost no time to adjust to the feel of the q-rings and switching between bikes is pretty much effortless. 2) My spinning efficiency is improved on the q-rings, as they simply feel more natural. My cadence did increase a bit and with less effort. 3) My legs were more sore after using at the beginning because I was engaging my hamstrings more, which is where I felt the soreness most. My regular round rings put more emphasis on my quads. However, I starting to find that I'm stronger on my regular rings after riding the q-rings, most likely because my hamstrings are definitely getting stronger from the q-rings. 4) My knees hurt less and I feel less fatigued after long rides. However, this did not happen right away, as you need to finish the break-in period that Rotor describes on their website. 5) Shifting is very good, but definitely a notch down from my full Campy setup. I feel it shifts more like my previous Record 10 group (i.e. less smooth and a bit noisier). I haven't had a single dropped chain after 400 miles. 6) I must admit they look rather cool.

I'm not certain I climb better yet, but will find out after I try the Horrible Hilly 100 next month (200K and 11,000 ft of climbing (18% grades on some parts)). Should be interesting/painfull. I did it last year using Campy Record 10 (compact crank with a 25t on the rear)

Lastly, the inner rings are far less ovalized than the outer, so it's tough to feel the difference between my bikes while climbing. I feel most of the difference when in the big ring. I will try to remember and post how they/I performed.

Strengths:    Pedaling efficiency particularly at max effort

Weaknesses:    A little pricey

Bottom Line:   
After a knee injury earlier this year I decided to try these to see if they might help in preventing a recurrence. As a road racer I was reluctant to try something that might compromise performance so I put them on a training bike before I rode them in a race. Pedaling in circles on the flats was more efficient but the real surprise came under max effort when out of the saddle climbing and particularly sprinting in a break or for the line. They are definitely smoother under pressure and give confidence that all of the effort is being transferred into forward momentum-there is no sudden and noticeable change in cadence from the top/bottom of the pedal stroke. They might not be everyone's bag but they're not coming off my bike.

Strengths:    awesome chainrings great on climbs and time trailing. bit expensive but worth it.

Weaknesses:    none

Bottom Line:   
When i first saw the q-rings on Carlos Sastre when he won the tour de france 2008. i was amazed. Then i researched on osysmetric rings the bio pace of shimano. too make things short. i bought mine then put them on. On my cervelo Team soloist. I didn't even feel the difference but noticed i could last longer on the big chainring even on big climbs and long flats. even my teammates were surprised that i could keep up with them in the ttt.

Strengths:    better on flats when you get use to them, less stress on knee joints.

Weaknesses:    I didn't find i would climb as good and definateley did not sprint as fast,made my leg muscles crap up nearly all the time .Far too expensive £148 , not worth the money .

Bottom Line:   
I've had these rings on for two months now,they seem to give less stress to the knees , however they seem to cause more stress to leg muscles and i have been much more prone to cramp when sprinting or climbing ,i'd say i don't climb as well with these or sprint as fast with these, but they do feel smoother if your on flat road or turbo trainer where your sitting down ,i'm going back to round rings , most of the teams in the tdf use round rings , Contador climbs and won on round rings and Cavendish sprints superfast on round rings ,i have gave them a good go though , but not for me as a road racer .
