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.

T-Lab X3

Frameset starting at $3,750
Complete bike starting at $4,650

The critically-acclaimed T-Lab X3 continues to redefine all-terrain performance. If you're looking for the ultimate one-quiver bike, look no further.

Key Features

Proprietary Shaping

Unique forming capability produces an exceptionally profiled titanium frame that delivers 30% more lateral stiffness and related performance versus leading round-tube Ti frames.

Mega Wheel Clearance

Compact back triangle now accommodates tires up to 700X45c and 650BX51.

T-One Dropout

Exclusive, future-proof design offers an exponential advantage with regards to stiffness, shifting precision, adaptability and durability.

Top-Level Ti

Seamless, Grade 9 (3Al - 2.5v) titanium is cold-worked to optimize stiffness-to-weight in the frame without affecting the inherent qualities of Ti.

Quietly Strong BB

BB-386 titanium bottom bracket shell optimizes lateral stiffness where it counts. T-Lab’s meticulous post-machining ensures a “creak-free” ride.

Singular Fabrication

Made completely to order based on rider specifications and preferences.

Rider Feedback

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.
Cycling Plus
X3 Review
One word: SICK. Impossibly quick bike that’s just looking to go faster.
Louis Fortin
Montreal, QC
Really sets itself apart from just about every other titanium gravel bike on the market today. "The X3 can do it all."

X3 Review
The X3 is really sweet. Very solid and responsive frame, tracks beautifully.
Bob Steimle
Salida, CO
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.
