Wishlist: Rotor Q rings

So I've been trying to think of a better name for the Monday post when i take a look at something that's kinda cool (new or otherwise) but have really never managed to figure out one so it's just been the name, but this week we're going to try with something else.... the wishlist because usually most of this stuff is pretty cool and I do wish that I could have it, so here it is.  Wishlist for this week is something that's bike related, which may be due to the fact that I'm finally back on the bike more, at the expense of running, you can't win em all.


So today's post covers something that I saw a couple years ago when Cervelo started using these on their team bikes, or atleast some of them did and they did a little feature on them.  Now anyone will know that your chainrings (the big circular rings in the middle of your bike) are usually circular as are most gears, but these rings are different in that they're ovalized.  The idea behind them is that because your pedal stroke is not even throughout.  If you imagine a clock pattern on how you're pedalling the majority of your power is only generated effectively through 1-6, and more specifically between 2-5 which leaves leaves a good three quarters of your pedal stroke not producing a whole lot of power.  So to fix this one can get a more efficient pedal stroke but that is only effective for so much more power

Essentially to generate more power you can either get a bigger chainring (more teeth) or just push more power.  Q rings are ovallized so that in the portion that you can use your biggest muscles the quads, the ring is like a 56 tooth cog, and in your weaker portion, it's like a 50 tooth, which gives you the joys of a compact and a double.  Proteams use them because you get a more effiicient pedal stroke, less lactic acid build up, and it's easier to ride them.  But don't take my word for here, check this out from the now defunct Cervelo Test Team.


I'll let you know when I get a chance to try these out, but they look like they should be pretty good, and common who doesn't love new gear for your bike
