Absolute Black Spiderless BB30 Oval Ring
The Absolute Black Spiderless BB30 Direct Mount Oval Ring is a simple step toward significantly augmenting your ride, through its' lightweight, stiff construct, and clean good-looks. Is oval shape promotes optimal power transfer by maximizing the section of the stroke where power is produced, and minimizing resistance where it isn't. To put it simply, oval rings provide you with a few more teeth in the stronger part of the pedal cycle, and take away a few teeth in the weaker section. For example, a 32t is equivalent to 30t at deadspot and 34t at the power zone. This results in a more efficient pedal stroke and more tire traction in the rear. The Spiderless BB30 Oval Ring has the famous narrow-wide tooth profile that retains the chain snugly, allowing you to end things with your bulky chainguide.

I was running a 28T round ring on a Sram XX1 10-42 setup, and the smallest chainring for my Press Fit BB30 XX1 cranks was a 30T oval, and this means that the "easiest" is 28T and the "hardest" is 32T, so I was afraid that I would struggle considerably. I recently went from an Orbea Rallon with a 2x10 running 22-36 in the shortest ratio on 27.5 wheels to a Specialized Enduro 29er with a 28-42 short ratio. It's a longer ratio and on bigger wheels, so I was having trouble pushing it on the steepest climbs I do. I hope that gives you some perspective on why I was worried about installing a 30T oval.
Well, having installed it, it's been amazing to me how I'm pushing the same gear or even a taller gear in all climbs. The ease with which I can put down power in a more controlled way is a great help. I've gone for three rides, two short ones (under 25 minutes of continuous climbing) and a longer one (one hour and 20 minutes of all-out pedalling). I've gone on pavement, mud, technical climbs, and I'm doing better everywhere. On the long ride, for example, I got 7 PRs and 3 2nd best personal times on all 10 segments!
I definitely recommend this product. I believe that, with some time, this might eventually become what higher-end bikes ship with from the OEM.
