Oval chainrings are nothing new, but single-ring drivetrains may breath new life into the asymmetric design.
Riders looking for the top-notch 11-speed group from SRAM but want it in black can now have their cake and eat it too. SRAM today announced the new XX1 ‘Black,’ a gunmetal version of XX1. SRAM also added injection-molded plastic crank boots and a high direct mount front derailleur cover to mask that unsightly stump where your front mech used to go.
SRAM has announced the release of direct-mount, spiderless chainrings. While their current model X9, X0, X1, X01, and XX1 cranks have been capable of accepting direct-mount rings since their inception (dating back to 2010 for X9 and X0), SRAM has been relatively slow to produce the accompanying rings.

There is a lot of hubbub in the cycling world right now in regards to drivetrains. Shimano has their Di2 system, SRAM came out with the XX1 and a couple independent companies are producing oval chainrings.
If I had to name the source of the most considerable frustration during my time as a mechanic it would easily be press-fit bottom brackets. Even a skilled mechanic armed with expensive measuring tools, bearing presses and sleeve-retaining compounds, is not guaranteed a good interface.
Following the release of the one-by XD driveshell upgrade option for the ISO and ISO DH hubs, now offers the same upgrade for all mountain wheelsets.

After years of living a mundane spandex-clad existence hammering out road miles, Di2 is finally ready for some real fun. That's right, XTR Di2 is here, or almost here. Shimano says it'll be available this fall, and it's designed to work with the recently announced XTR 9000 11-speed group.
From SRAM X1 comes the integrated drivetrain engineered in Germany for every rider and every trail. The simple, smart and synchronized design delivers confidence in the face of any terrain—from cross-country racing to all-mountain adventure.
We take one more walk around the pits at Laguna Seca to highlight this year's most promising gear.
No matter how excited we get about the next best widget, in the end it doesn’t really matter what we are riding, just that we are. A massive amount of work goes into creating this gear guide, but do we actually need any of this stuff? No. I’m looking at all the white space on the page below my blinking cursor, wondering what to write, because none of it matters. In fact, you should stop reading this immediately and…run to your shop and demand they put this group on your bike right away.
Reeb is one of the first American companies to incorporate the German-built Pinion gearbox on one of its bikes. The 18-speed gearbox is mounted to a specially modified Reebdonkadonk rigid fatbike frame. The Gates belt drive propels 29-inch wheels mounted with 3-inch-wide Surly Knard tires.
