When it rains, it pours, it seems, every time one brand introduces new single chainrings, a competitor slips one out within days. This time, Absoluteblack’s 94BCD oval narrow-wide chainring comes hot on the heels of OneUp’s complete collection. But, AB’s founder Marcin is quick to point out some of the differences that separate his oval rings from others. But first, let’s have a taco.
Their new Taco Bash Guard fits on standard ISCG05 mounts and uses a special polymer with glass fibers for the bash plate. They say this makes it stronger than the typical plastics used on other bash guards, helping it hold up to small and medium hits, but still letting it breakaway on major impacts to save the frame. Replacement guards will also be available separately. The metal mounting plate is 7075-T6 and will be anodized in a darker gunmetal gray than what’s shown here for production versions.
It’s sized to protect a 34-tooth round chainring, or a 32-tooth oval one. Retail will be €59.99 / £43.99 / $67 when it goes on sale in a couple weeks.
Now, about that oval…
Absoluteblack already offers oval chainrings for SRAM direct mount (GXP & BB30), 104BCD and Raceface Direct Mount. Now, they’ve got a 94BCD, too, which should fit just about any recent SRAM spider below XX1 level. It’s available in 30, 32 and 34 tooth counts, each offering a +/-2 tooth count equivalent in the strong/weak portion of your pedal stroke.
Here’s what Marcin told us about his oval rings:
“…every single size has to have a bit different clocking and ovality and this is what we do to further optimize the ride. This is why we do not list ovality percentage and clocking. We only give an estimate of 11% ovality so people understand. But this is just an average. It is really important to pass that information at this stage as this is what defines us from the rest. Every size of the oval needs to be done a bit differently as pedaling habits change with the size. For example the smaller the ring the bigger the ovality is as you will use it more on steeper uphills. Also clocking changes as pedaling behavior changes.”
These are available now on their website.
