I decided to give the Kredo a mini-makeover courtesy of the good folks at Fort Worth Cycling.
- Switched from silver to white Fizik bar tape
- New white and black Arionne saddle (had my old Arionne for 3 years)
- Put on a set of Rotor Q-Rings (elliptical chain rings).
I’m loving how the white tape and saddle changes the personality of the bike ever-so-slightly (white is the new black). But the big change here are the Rotor Q-Rings.
I’ve been considering a set of Q-Rings for about 2 years, but only recently decided to take the plunge after learning a couple ThinkCash Racing teammates were using them with some success. I went for the “aero” rings in 53/39 which are black and quite frankly, look pretty badass. The science behind Q-Rings is simple – round rings force you to pedal at the same speed through the entire stroke. As a results, you spend just as much time in the dead zone (at 12 and 6 o’clock) as you do putting on the power zone (between 2 o’clock and 5 o’clock). Q-Rings are shaped so the chain ring is effectively smaller as you enter that dead zone (equivalent to 50 or 51 teeth) . It smoothly accelerates your feet through the dead zone and gets you back on the power sooner (where you push the equivalent of 56 teeth).
I’ve only done one easy ride on the Q-Rings, but they pedal just like round chain rings (there is no choppiness). I did notice that I was pedaling at a slightly higher cadence then normal, but too early to tell if that is the result of the rings. There have been several studies of the Q-Rings showing power improvements of ~5% at threshold and above. Considering how fast our company Tuesday Night rides are getting, I’ll take all the help I can get. I plan on doing some testing of my own in the next week or two, so I’ll let you know what I see.
