SRAM Releases Wireless Eagle Drivetrain and Reverb Seatpost

Big news from the mountain bike world as SRAM released a long-awaited wireless drivetrain and dropper seatpost. The new Eagle AXS system is based off their existing 12-speed mountain bike drivetrain, but nixes shift cables for a wireless system. Additionally, their new Reverb AXS seatpost utilizes a similar wireless system to actuate the hydraulic internals.

Why bother messing with a system that has worked for decades, you may ask? SRAM claims the Eagle AXS system is lighter, shifts faster, gives perfect actuation every single time (pending the fact that your derailleur hanger is straight), and allows you to set up your shifting just the way you like it via the programmable shifter.

Speaking of the wireless shifter, the whole system is customizable via SRAMS AXS smartphone app. All three buttons can be assigned to your liking, similar to how Shimano’s Di2 wireless road shifting is designed. The third button will likely be best suited as a “sprint” button, eg. drop a bunch of gears to bust past the slowpoke ahead of you, or even to control the Reverb post.

For anyone who’s ever owned a Reverb, you surely know that horrifying feeling when your dropper inevitably gets squishy after a few months of riding. The reason? Air mixing with the oil inside the system and compressing. The fix? A costly or complicated bleed of the whole system to purge the air. Fear not, those days are gone. The new Reverb contains a nifty little port called the “Vent Valve,” which provides for a super-quick way for a user to purge the system of air, similar to Bike Yoke’s Revive dropper post.

The Reverb comes in 100, 125, 150, and 170mm drops and will fit 30.9mm, 31.6mm, and even 34.9mm seattubes. 

Amazing technology used, no one could have imagined such amazing ideas, thanks for posting, this is really interesting to watch.

IFHT Films knows a thing or two about mountain bike humor, and their latest short tells exactly what it’s like to get into the world of mountain biking. It goes something like this: see someone else having fun on a bike, buy sh***y bike, hate it. Buy better bike, break it. Buy nice bike, love it. Get hooked on the sport and empty your wallet on it. We can all relate, can’t we? RELATED: Micayla Gatto + IFHT Films = Kendrick Lamar and Bikes

Walmart Just Launched A Proper Mountain Bike

There’s a new player in the bike industry, and it’s a rather familiar but unexpected name: Walmart. Technically, their new hardtail is being sold online through the brand known as Viathon, but it's still owned by Walmart. The retailer's move into the high-end bike market shouldn't come as a huge surprise considering last year's expansion into selling outdoor goods.  RELATED: Nico Vink on the Evolution of Freeride Walmart's heirs, the Walton brothers, are also huge cycling fanatics.

Sam Pilgrim is known for getting rad on two wheels, and has even gotten pretty rowdy on a tricycle. Now, he's upping the ante with a quad. Pilgrim explores the bike's capabilities in a variety of disciplines, including urban downhilling, wheelie-ing, skatepark, and drifting. Despite its somewhat-unwieldy appearance, the quad performs surprisingly well.
