Watching the open O-1.0 roll by is like seeing a Stealth Bomber fly overhead. You marvel at the visual experience sure but it's the knowledge that you're witnessing one of the most technologically advanced machines of its kind in action that really captivates you. Gerard Vroomen Andy Kessler and the team at open didn't set out to dabble in the status quo which required unacceptable trade-offs: strength for low weight or stiffness for ride quality. Rather they set out to break the mold. To accomplish that goal they challenged conventional wisdom and adopted the mantra that every aspect of the modern hardtail 29er frame could be improved. The result of this relentless pursuit is the O-1.0.They started with the material itself. There are many myths surrounding carbon fiber. One is that the more 'high-modulus' carbon fiber you use in constructing a frame the better. The simple fact is that though high-modulus carbon is stiffer it's also more brittle and thus weaker. So for the O-1.0 open used stiffer lighter carbon where it made sense and stronger carbon where it was needed like in the tapered 1 1/8 to 1 1/2in headtube. open calls this blended approach TRCinTRS for The Right Carbon in The Right Spot a tongue-in-cheek nod to the industry's love affair with acronyms. The result of the TRCinTRS approach was the creation of the lightest mountain bike frame ever to pass the German company EFBe's structural integrity tests which are some of the most rigorous in the world. Another myth that open was determined to put to rest is that carbon mountain bikes can't have a compliant feel. One look at the O-1.0's profile and you'll notice that the tubing slims down from the front of the bike to the rear. The seatstays in particular are razor-thin when viewed from the side. The purpose of the slender tubing is to provide a little vertical flex in back for comfort without sacrificing lateral rigidity. The key phrase here is 'a little' as open points out that f...
Arc'teryx built the Men's Alpha FL Jacket to serve as a fortress against weather that would otherwise threaten your fast-and-light alpine climbing. This minimalist shell features waterproof breathable Gore-Tex Active fabric burly fabric reinforcement at high-wear areas and a trim fit ideal for unrestricted motion and precise movement. Everything about this jacket is squeaky-clean and spartan-esque from the utilitarian feature set to the legendary Arc'teryx build quality.
