Light, nimble & tire clearance-capable!

With all carbon parts in the build, my size 54 Crux weighs in at 17 3/4 pounds, with a 700 x 50c/2" tire set on it. Great lines, light, super nimble and with additional downtime bottle mounts... well thought/designed!

This is THE bike!

This will be my 3rd gravel/cyclocross bike in the last 5 years. Just couldn't find the one that felt "one with me" until this Crux came into my life. This bike is exceptional! I literally feel one with the bike. Completed my first successful cyclocross season and had tons of fun on the Crux. Geometry is great, the head tube angle makes pedaling through sharp turns so easy, the bike is so light and nimble you feel like you have an unfair advantage. Looking forward to putting it through the ringer during gravel season.

Great all around bike. After

Great all around bike. After ridding “gravel” bikes as my road bikes for the past 10+ years and receiving a custom ti, big tire grav bike I wanted to get a road bike. While the Athos was appealing, the 32mm tire clearance and 74 degree headtube angle (my size) was polarizing. So I went with the big tire Athos, the crux, and I am pleased with the decision. It is very light, very stiff, versatile, looks great, and as much road bike as I need. GRX DI2 build (2x), carbon bar/post, normal stem, power meter, normal saddle, Terra CLX wheels, 35mm slicks, SPD pedals, cages (3), pump, blinky lights, computer, bell…17.5 lbs in a 61cm. Great platform for the two wheel sets one bike set up.
