TNT1 Posted April 12, 2007 Share Didn't Sh!tmano bin their attempt at square rings years ago? Link to comment Share on other sites More sharing options...
Ivanb Posted April 12, 2007 Share Yes but there is a huge difference see www.rotorbike.com Link to comment Share on other sites More sharing options...
4feet Posted April 12, 2007 Share We ride the TT Q Rings (54/42) on the tandem and can state that:   1. There is definitely an improvement in our ability to "turn over" a heavier gear. 2. Recurring knee pain (age related )in races has gone completely. 3. Top end speed has been curtailed somewhat - spinning out at between 70-80 kph. Stoker does not see this as a bad thing!   So......recommended by an aging enthusiast Link to comment Share on other sites More sharing options...
Ivanb Posted April 12, 2007 Share 4feet, you can look at moving the Q Ring to position 4 and this might help your 'spin out'. Link to comment Share on other sites More sharing options...
Marius Posted April 12, 2007 Share I'm just waiting for the LBS to tell me my middle blade needs to be replaced then I'm also getting Q-Rings for the Mtb. Link to comment Share on other sites More sharing options...
4feet Posted April 12, 2007 Share Thanks Ivanb will try that. What effect will that move have on the other aspects of the ride...flats and climbs? Link to comment Share on other sites More sharing options...
Ivanb Posted April 12, 2007 Share its trial and error. It should make a difference. If that doesn't help try position 2 Link to comment Share on other sites More sharing options...
Ivanb Posted April 12, 2007 Share Guys we even offer a 30 day trial period if you not happy I will refund the money spent. Obviously the rings must be in good condition, etc etc. Link to comment Share on other sites More sharing options...

PhilipV Posted April 13, 2007 Share ivanb,what are they like on a mtb, my common sense tell me they will be just as effective. worth it? Link to comment Share on other sites More sharing options...
prinsses pink Posted April 13, 2007 Share Hi... I ride with them and they GREAT...you save alot more energy ! Link to comment Share on other sites More sharing options...
Ivanb Posted April 14, 2007 Share On a mtb they are great from what feedback I get. The guys are impressed with better traction and an extra gear. Also they say when you need the small gear you don't feel like you are spinning and going nowhere slowly. We had a crazy rush before the Epic and so far no one has called to replace blades or k-k on me to say they were no good. So thats good news that they are lasting. The Wharthog guys had some very good things to say. Link to comment Share on other sites More sharing options...
The Guy in Pink Posted April 14, 2007 Share I see a negative aspect with oval rings for a road cyclist in endurance events.Effectively a length of the chain is lifted vertically and dropped about 20mm  twice in each crank rotation, or 180 times a minute at a cadence 90.  Although the studies show an increase in maximun power, a road cyclist spends most of his time riding no more than at 60% power.  The effort of accelerating and lifting 100gms of chain 30 000 times during a 3 hour event will probably negate the benefit of an extra 12 watts for the 5 seconds of the sprint when maximun power is needed.The Guy in Pink2007-04-14 02:54:35 Link to comment Share on other sites More sharing options...
Ivanb Posted April 14, 2007 Share Guy in pink, No way there are studies showing the increase in power. It has nothing to do with what you say as standard round rings consume most energy at the dead spot where you try to go forward while pushing down. Now with q rings the drive and power are placed in the correct position so that the bike moves forward effeciently and with the most economical power source.Power increases dramatically, effeciency improves and speed. The dead spot is reduced and with the increase of the accelaration through the dead spot is increased and there fore made easier to travel through all but eliminating the waste of power and energy. riders ar now seeing these results on their own powermeters etc. Get a set and prove it to yourself Link to comment Share on other sites More sharing options...
