ALL COLNAGO BIKES ARE BUILT TO ORDER – PLEASE CONTACT US TO DISCUSS YOUR  BUILD AND CHECK THE LATEST LEAD TIMES BEFORE PLACING AN ORDER. IMAGES ARE FOR ILLUSTRATION PURPOSES ONLY.

The Colnago G4-X is built for riders who demand uncompromising performance on gravel, cyclocross, and everything in between. Handmade with Colnago’s advanced carbon construction, the G4-X blends race-level stiffness with confident handling and refined ride comfort, delivering a platform that feels precise, planted, and ready for the fast line.

The updated frame optimises tyre clearance, stiffness-to-weight, and vibration diffusion, giving the G4-X the capability to excel across technical terrain, high-speed gravel, and race-intensity efforts. A balanced geometry promotes confident cornering, sharp response, and long-haul efficiency, while the integrated cockpit and internal cable routing keep the entire bike clean and aerodynamic.

Paired with Shimano’s latest GRX Di2 12-speed, the G4-X gains ultra-reliable shifting performance designed specifically for the demands of fast gravel. Wide gear range, powerful braking, and the precision of fully electronic shifting make it a drivetrain that thrives under pressure.

Whether you're taking on the biggest UK gravel events, racing CX, or building a high-performance all-terrain machine, the G4-X stands out as Colnago's purest expression of off-road racing DNA.

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.

MY CHIHUAHUA LOVES THESE BALLS!!
Color: Samll Set of 8
My little chihuahua, BamBam, is addicted to balls, especially little balls that squeak! However, any balls that have material on them, BamBam will tear them apart, swallow the material and then get an upset tummy! These balls saved the day! BamBam LOVES them & she cannot tear them apart! They hold up so well! No matter how much BamBam plays with them, they keep squeaking away!

Squeaky ball
Color: Large Set of 4
Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.
