where did you get your time trial version of the rings? I've seen them on the internet once somewhere, but no where readily available.

If you're lucky enough to be British ( :lol: ) they're available from http://www.cyclepowermeters.com/osymetr ... -148-c.asp

I've put extensive miles on Qrings and tried endlessly to get Osymetrics set up on my TT bike but eventually gave up. The shifting was awful but the feel was great. Enter the new QXL rings. In my mind they're the best compromise of all the non round rings. They produce a feel similar to Osymetrics but shift smooth with zero problems especially with the new Red.


Yes, I'm sooo happy about the QXL rings, too! No problems with shifting as well on my SRAM Red.

Contact Jonathan Carvner at OsymetricUSA.com that is where I got mine, might be a special order.

I emailed the OsymetricUSA guys once, they said they were prototyping the TT rings now and that they would put them up in the store in the next month or so. This was like November or December.

Okay guys. I need some help here.

I´m thinking about buying a pair of O.Symetric chainrings to try out on my road bike, and TT this winter. The thing is that I ride as a Junior-rider. This means that I have "gear restrictions". Right now, the heaviest gear I can use is a 52t chainring combined with a 14t cassette. This gear is quite easy if you know what I mean (50 km/h++). As some of you said; the O.Symetric is "easier" than round chainrings. So, will this mean that I will "spinn out" my gears faster than the other riders?

Thanks.

Roll-out is just how far the bike goes with one full revolution of the crank. For a 52t chainring, that's 52 teeth-worth of chain whether it's an oval 52t or a round 52t or an osymetric 52t. If you can achieve a higher average cadence with the Osymetric due to the easy effective ratio in the dead spots, then you'll go faster on the Osymetric than on round rings.

You should probably ask your local officials about how they handle Osymetrics. You don't want to spend hundreds on new chainrings only to be disqualified by an unexpected clause in the rulebook (or by an uninformed official).
