"Quiver killer", "Swiss Army Knife", "If I could only have one bike". We say this but "that bike" always comes up short somehow. We optimized our AFS suspension around an AM 29 inch platform and gave up nothing. The Onset 140 truly is the "have your cake, and eat it too, bike". So enjoy your cake... with a grin that your buddies are sure to get sick of.

As mountain bikers, we thrive when things get nastier, riskier, faster. The point at which terrain and speed force lines between mind, body, and bike to blur. This is the zone we thrive in, both on the bike and while designing it. MORE risks and challenges are where MORE rewards are found. To that end, we’ve asked, how much MORE can we push the Onset. It turns out quite a bit. Enter the Onset MT, our definition of “full enduro”.

One word describes this bike: Exact. The Onset 120 is a serious trail machine that turns 100% of your effort into speed. We made this bike agile and efficient, but since it shares the same DNA as it's longer travel sibling it still straight up smashes when it needs to.

Breaking the Mold with a 29er Bike As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It's shown people the light of how high volume, large diameter tires can vastly improve the ride experience. It's also done a bang-up job dispelling the myth that big tires make you slow. Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business. "Lean back, hang on, and ride that wild horse." -Thor - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 29" x 3" tires

With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat tire trail bike that can truly handle anything you want to attempt. If you do an equal amount of off-road touring as you do hitting trails, Wednesday's ability to play both parts equally will suit you well. Or, if you're looking for a fat bike and don't need the fattest tires on the market, Wednesday's 26 x 4.6" tire clearance is just the ticket.
