definitely try before you buy

even on pro teams sponsored by rotor you have

-riders that tried em and permanantly switched
-riders that tried em, hated em, and tried em again after teamates made the permanant switch
-riders that tried em, hated em, and don't use em

I was hoping your lines of info were links.....

Your own thoughts are ?

lol, no personal experience ive been interested but after my own research it seems too hit or miss for me to invest the time/effort

check out cervelo test team videos on Youtube, a few of them spotlight the rotor cranksets with rider insight from the first two lines i listed

hope this helps

This rotor thing looks to me like a rehashing of the old Shimano Bio-pace technology of the early 80's. I had it back then on my single and I have to say that I really felt no difference. It was kind of a flash in the pan. It sounded really good on paper, but in reality, it didn't really make an impression in the marketplace.
If you feel that your pedalling is choppy, you need to train yourself to pedal in circles, not to fixate on the down strokes. The best way to train smoothness, is to spin on an old fashioned set of rollers. This was a very much more popular training aid back in the day and we who used it, were forced to be smooth or we would end up on the floor. I used to be able to put on and take off jerseys when spinning. The difficulty, which made it a casualty of stationary bikes and wind resistance stands, was that it took great concentration to ride on the center of the rollers and this made time move like a glacier! It was incredibly boring!

Been racing on them for nearly 4 years. I like them, they shift fine once you have the FD set right. You'll need to play with the clock/counter clock settings to match it to your pedaling style, I'll run the inner and outer one point apart on my climbing bikes.

They are a personal preference item, but I know a lot of very good racers who use them.

Might be good to have some understanding of the current product before making a comparison to a 30 year old failure. The ramping on Osymetric and Q rings is the exact opposite of Biopace.

I installed a set of compact Q Rings (50/34) on my Record 10 equipped bike. I love them! I put about 120 miles on them over the weekend and am very impressed. Shifting is just as nice as it was before, and on my reg training routes I find myself pushing 1 bigger gear for any given situation than before with less "burn". The down side is I spin out rather easily now with my 12t where before I would just use my 13t (down side being campy cassettes aren't cheap, especially for 11t clusters lol). I am not a small rider weighing about 210lbs and I find that climbing is great. We have a ton of kick azz climbs here, some 18 to 22%, climbing is notably smoother for me now. I am riding them in the recommended starting "regulation" holes but hope to mess with alternate orientation this weekend.

Snake oil.

Okay, more helpfully, claims about biomechanical superiority, increased power, reduced cramping, etc, should be viewed with suspicion. Some riders are going to like them. Some are not. There's ample reason to be skeptical of claims that non-round chainrings are superior in a clear and generalizable fashion. Go ahead and try them. You might like them; there are definitely riders out there that do. I just wouldn't take all the hyperbole very seriously.

To put this in perspective, things like this come in cycles. Asymmetric rings are not a new idea; they date to at least the middle of the 20th century, probably earlier. They've hit the scene, become a fad, and then faded. And when they've been popular, the arguments made for them have been broadly similar to what you hear about the same products today, albeit without all the sports-science mumbo-jumbo. Round rings have consistently won out over asymmetric rings. It's a safe bet that there are some pretty good reasons for that.

...and then there are those chainrings on Hinault's bike...

Noticed this thread, what's the word on Osymetric rings? Wiggins and Millar are using them this year and I believe Millar is sponsored by Rotor?
