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.

Neat gadget
Color: Gold
Neat little gadget. Works great, easy to use and has a light indicator for temperature range. Keeps a cup of liquid hot right to the bottom.

My tea stays warm to the bottom of the cup!!!
I am so glad I purchased this mug water. I drink tea all day but it cools down quickly. Since I purchased this mug warmer my tea stays hot to the bottom of the cup. The temperature is adjustable so you can keep your drink at your desired temperature. The top is glass and wipes clean easily. I like the rubber gasket that fits on top of the warmer. It keeps your mug in the center of the warmer and should you have a spill it catches the liquid. I've been using it every day for over a month now and it's going strong and is reliable. Perfect for personal use or as a gift.

Keeps my coffee as hot as I want it to be
Color: Silver
This coffee warmer is much better than the candle warmer that I was using for my coffee before. With a range of 3 temperatures, I have a choice of temperatures from hot to very, very hot, and the warmer shuts itself off after a while, just in case I forget. The description advises that ceramic cups do not retain heat as well as flat-bottomed cups, but I have not found that to be a problem. Coffee in my ceramic mug stays as hot as I want it to be. The knob on the side makes this warmer easy to turn on and to select a temperature, plus I feel that it is a good value.

Perfect Mug Warmer
Color: Black
I bought this to replace one I'd had for more than 25 years & I'm glad I got this one. Keeps my hot drinks hot for hours & will shut off after that. Quickly heats back up when needed. Very sleek looking. Easy to set up. Just take it out of the box & plug it in.

I love it for my workspace! Hot tea all day
Color: Wood Grain
I love this item. The size is perfect, as I prefer something less bulky for my work desktop. It isn't as fancy as others that has the digital display screen, which is fine by me, because I don't necessarily need that. The knob and different colors that indicate the temperature range works fine. The temperature on this thing works fantastically well for me. Using it on the lowest setting keeps my drink nice and hot in a cold office. I use a heatproof glass teapot with this and its a good fit. It keeps my tea hot throughout the day, so I am able to pour smaller amounts of drink and take my time sipping it throughout the day without worrying that it will get cold. At point I almost forgot that it has an automatic shut-off safety feature when I noticed it was off. So that is a good feature to have. I highly recommend this.
