Ha! Kinda like the 17 year locusts??Peanya said:Do a search, or check Sheldon Brown's site. They make a reapparance every 10 to 20 years or so, getting much hype. Shortly after the hype falls away, no one gets them for another 10 to 20 years.
Shimano provided research on their BioPace rings PROVING that they were 3% more energy efficient. Of course it's just possible that those lab results didn't transfer to the real world all that well.OldZaskar said:Was any research done on the various rings, e.g. big vs. small. I could see why a eccentric 52 would not be much use. But I have wondered (since my last eccentrics rings - 1987) if an eccentric small ring would be of use. Maybe only the granny on mtbs and roadbikes with triples? Seems like it'd be.. could be of benefit for very low cadence climbing.
My first post here... I don't agree with your conclusion. You only have to look at the widespread use of a ring like Rotor's in Europe - used in both road and mountain biking disciplines. I don't think things are as 'clean cut' as you describe.skyliner1004 said:its so weird that it happens, haha. i had a long thread on this not too long ago in components, and the conclusion was that eccentric chainrings such as the RotorQ chainrings ARE NOT more efficient and DO NOT make you faster. i guess i'm sticking w/ round...
The problem is that widespread use does not tell you if a product works or not. This is particulary true in sports, where in a quest for better performance, millions of people spend large sums of money to buy products of no value whatsoever.markw1970 said:You only have to look at the widespread use of a ring like Rotor's in Europe - used in both road and mountain biking disciplines.
P. T. Barnum said "There's a sucker born every minute" In the 20 years since Shimano Biopace there are at least 10 million new suckers. I guess that is a good marketfrmrench said:I'm starting to see various versions popping up again lately from both indie manufacturers (Moto) and main line (Shimano). The concept always seemed to have some validity to me. Anyone using them or have any knowledge of the new crop?
More likely, because a sponsor is paying a great deal of money to get their component visible.bike981 said:Do any pros use eccentric chainrings? Presumably their teams have the money, gear, and motivation to go after even a small efficiency gain.
This is absolutely true. My observations during my expensive training in Europe has shown me that Rotor chainrings create a huge performance advantage in Europe. However, as shown by the nonpresence in the US, the Rotor chainrings do not provide a benefit while on US soil. As such, I have a set solely for use in Europe.markw1970 said:My first post here...

Nah. It's just that many ppl here have seen the trends come and seen the trends go, so they don't get all exciticated about the umpteenth marketing push for non-round 'rings.markw1970 said:Wow some closed minds out there... surprising really.
