Gravel Bikes

Underlying the growing popularity of gravel bikes are the notions of versatility and adventure. With a properly designed bicycle frame and the right components — including disc brakes and wider tires — you will be free to take on whatever road you choose, on and off the pavement. The best gravel bikes are all-around performers, combining power transfer, agility and riding comfort, as well as offering superior traction and stability on any surface.

The accommodation of tires (up to 700x45c), combined with the longer-range nature of gravel / adventure ride, result in a frame design that typically features a relatively longer wheelbase and a more upright, sustainable riding position. Whether you are looking to occasionally ride off the tarmac, or are seeking to ride mostly off the beaten path, the best gravel bike can get you there and deliver loads of fun along the way.

Rider Feedback

On the hills it was snappy out of the saddle, and the handling on the flowy turns felt solid. The top impression the X3 demonstrates though is the smooth ride compliance it give over the rumble and bumps. Your one of a kind frame design lives up to your claims.
Scott Dayberry
Colorado Springs, CO
The bike is supple and stiff and handles beautifully, very impressive piece of work!
Hill Abell
Austin, TX
Has a feel like no other titanium bike. The much-lauded compliance of titanium is ever-present, soaking up road vibrations, but the X3 also brings razor-sharp handling and response to the party. Pressing on the pedals produces an immediate reaction, with acceleration like a kick in the pants and great torsional rigidity that counteracts it and ensures precise control.

X3 Review
I have been too busy riding it every day to put all my thoughts on paper but suffice to say I feel like the happiest guy in the world. The ride quality and solid performance of this incredible frame have surpassed all expectations. Everything about this bike is absolutely perfect.
Daniel Straus
Toronto, ON
Really sets itself apart from just about every other titanium gravel bike on the market today. The X3 can do it all.

X3 Review
Just completed a ride from Seattle to San Diego. I have loved my X3 the entire 1800 miles. No creaks, no problems and best of all, it’s such a comfortable ride.
