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.

Mans XXL Light Baby Blue Linen Suit 6'5" 225 lbs
Mans XXL Light Baby Blue Linen Suit 6'5" 225 lbs "This suit fit me perfectly. I was unsure of fit initially so I looked at measurements carefully and selected -true to my size- On suits that arrived a size too big I used a strategy found on Google to shrink my suit. On the wash setting, set it to hottest water setting and tumble/time setting. On the dryer set it to longest hottest heat setting and two things will happen, it will take out wrinkles and be a perfect fit!

4.5 Stars.. Comfy, but Really Check the Size Charts
I love the material of this suit. Very comfy fabric. Out of the box, it was WAY less wrinkled than I thought it would be. The pics I took are of the suit are straight out of the packaging. When it comes to the suit itself, I really have nothing but complements. I will note a few items on the sizing: I am 6'3", 270, and I got the 3XL. The size chart says it goes to 260lb, and I think it is right, but with a caveat... Here's why: Pants: The pants actually fit me great. There is a comfort waistband, but I don't even really need it. I generally wear a 40" jean; 38" when they go to a loose fit.. The inseam is great as well. I am either a 32" or 34", but most 32" inseams are a bit short... Jacket. I tend to wear a XXLT or a 52L from a suit shop. The shoulders of the jacket fit fine. It feels OK through the arms and chest, but it is probably 1/2 - 1" away from a comfortable ability to button the jacket at my "gut". Thus my comment about sizing. I am a bit surprised that the pants fit so well through the waist but the jacket does not fit as ideally. Still - I think I am only a few pounds away from a good fit. So I kept the 5 star review with the note as the size chart does call it out... Being so descriptive here for your benefit.

 Pretty good suit
I am pleasantly impressed with the quality of the suit. Out-of-the-box, this suit fits me nearly perfectly and I may only have to do minimal alterations. I usually wear a size medium and the jacket fits me perfectly in the shoulder area. In dress shirt sizing, I usually buy a 15-15 1/2 x 34-35 sleeve length. The sleeves in this suit fit me perfectly, and the buttons are high enough so one can take the sleeves in a little over an inch, making the sleeves an inch shorter. This suit is a slim fit suit, yet the suit hangs loosely around the stomach area. Tightening up the stomach area is an easy alteration, and I may just move the button an inch to give me the desirable V-shaped look. Talking about buttons, the suit is only a single button jacket, and the cut is like a two button jacket. Why they make single button jackets is beyond me, but they include a second button if one wants to alter the jacket into a two button jacket. I understand the decision to make midsection a little loose as many people to have a belly. Yet this suit is slim fit, and if one wants the tailored look, one would have to move the button in or alter the jacket a bit. My typical pan size is 32x32 and these pants fit fine. The legs may be an inch long, so I would say these medium pants are 32x33. There is some extra fabric so one can let out another inch, and one can shorten the pants as much as they like. The fabric feels alright for a polyester suit.  Overall, this is a really nice suit, but does not have the complete tailored look like I get with some other designer slim fit suits. They designed this suit for someone with a little belly as well.

Not what I envisioned
The linen looks like cotton and the lapel is VERY wide. The sleeve are too long for the size I ordered. I had to spend an additional $50.00 for alterations.

costume and professional
This is a fun suit and would be amusing to wear to a date. It screams out pompous in a delightful way. I like the fit overall and while not perfect it wears well enough. Best of all is that I can dance in it. I attached some media so that you can get a crystal clear idea about what this suits appearance is. The bottomline is that most people will find this suit playful and maybe even a bit classy.
