OVERVIEW

A balanced gravel racing bike, to perform at its best in every context.
The G4-X is the result of optimizing all those factors that are important when you have to compete or go hard on dirt roads: handling, lightness, downhill rideability, stability, frame responsiveness, and, like all Colnago bikes, surprisingly wonderful to ride.

The G4-X is the new Colnago designed for gravel racing. This model is intended to replace the G3-X, using the best of what the Cambiago-based brand has learned in its important and storied experience in off road on cyclocross and, in road racing, with the V-Series bicycles, the carbon monocoque bikes made for the UAE Emirates and UAE ADQ WorldTour Teams.

The G4-X is the product of Colnago's off-road experience, which in CX has dominated and won everything that could be won. Some of the brand's most notable victories include those of Sven Nys, winner of six CX World Championships, and Wout Van Aert, who won two off-road World Championships with Colnago.

The concept of the G4-X is derived directly from the V4Rs, the bicycle that the UAE Emirates team and the UAE ADQ team use in the WorldTour. The two models share the design spirit and the aesthetical look. V4Rs was designed to be the perfect point of balance of everything that a professional rider needs. The same is true for the G4-X: the optimal balance of those features requested to win races on the dirt roads

PERFECT BALANCE OF ELEMENTS
It is easy to tell a bicycle by one specific number: the most aero, the stiffest, the lightest... Yet in the end, it is not one number that makes the pedaling experience. The riding experience is the result of the perfect balance of many factors, and it is this balance that we focused on to design our fast gravel bike.

The G4-X is the result of optimizing all those factors that are important when you have to compete or go hard on dirt roads:

  • Handling
  • Lightness
  • Robustness
  • Aerodynamics
  • Stability
  • Frame responsiveness


TIRE CLEARANCE
The nominal tire clearance of the G4-X has increased from 40 to 45 mm compared with the previous model. The Colnago G4-X is available either with standard two-piece stem+handlebar combination or with Colnago's Integrated CC.01 Carbon Cockpit, Wide version as standard but the road one is compatible as well. Since it has a regular 1 1/8 inch fork steerer tube, spread compatibility with third-party solutions is guaranteed.

INTEGRATED HANDLEBAR SOLUTION - CC.01 WIDE
The Colnago CC.01 Wide has more flare than its road counterpart, the Colnago CC.01, with 3cm for each side instead of 1cm. Like the basic version, it is a carbon monocoque, which allows for both significant weight savings and increased bike stiffness. The reach is 72.50 mm and has a drop of 120 mm. The stem angle at the handlebar is 82 degrees.

MOUNTING POINTS
The G4-X features features four riveted mounting points, two on the standard bottle cages location on the main triangle, plus one facing down on the down tube and one on the top tube. The Colnago G4-X can mount any type of electronic, both single and double chainring. In addition, it is compatible with UDH, a new universal rear derailleur hanger designed by SRAM.

A Good Offering From V8
Flavor Name: Peach Mango, Size: Pack of 6 (8 Fl Oz)
It's no secret that I'm a fan of the V8 energy drinks. This is a six-pack of 8-fluid ounce cans of V8 energy in the flavor duo of peach and mango. Out of all the V8 energy drinks, it's probably my second favorite behind orange/pineapple. It's easy to find and can also be found in a 12-pack on occasion. V8 falls under the Campbell's brand. There are 80mg of caffeine in each can of V8 energy. This is about equal to most cups of coffee. I've found when I drink one can to get started in the morning that I have a nice energy boost that allows me to get my morning routine going. The temptation I have to resist is to have too many of these. The cans are smaller and they have such a deceptive, smooth taste that it's easy to forget that you're actually getting a fair amount of caffeine. Too much caffeine is definitely not great and I find it really messes with my digestive system. So, this is definitely a drink I enjoy in moderation. The peach and mango duo has a nice balance to it. It lacks the spark of the orange/pineapple, however, it tastes substantial and I always feel like I'm getting a solid drink when I have one of these. V8 Energy has definitely gone up in price during the pandemic and some of the flavors can be hard to track down, however, I pretty consistently see peach/mango. While the price has gone up, it's still less expensive than nearly anything in the energy drink category except for the cheap stuff that isn't at all healthy. This energy boost comes from green tea and it's just a smoother energy boost without all the jitters and without a sugar crash. There are 50 calories in each can and each can actually counts as one serving of fruits and veggies. Overall, I'm a definite van of the V8 energy brand and Peach/Mango is my second favorite flavor duo. I get the boost I need, however, it's healthier and more evenly spread out without giving me the caffeine crash that I hate. While I have to drink these in moderation, when I need an energy boost the first place I'm going to look is at these V8 energy drinks.

Hands down best drink ever!
Flavor Name: Peach Mango, Size: Pack of 12 (8 Fl Oz)
The Peach Mango V8 is genuinely one of my favorite drinks ever. I honestly love these more than coffee or any caffeine drink I get from drive-thrus. I’m not a huge fan of carbonated drinks, so this is absolutely perfect for me. I’m actually the type of person who lets pop go flat before drinking it (yes, I know that’s weird 😂), so having something flavorful without carbonation is amazing. It has the same fruity, energy-drink type flavor that drinks like Bubblr or Alani have, just without the sparkling part. The peach mango flavor is so good and refreshing, and I always keep these stocked at home.

Great combination of veggies and fruits
Flavor Name: Peach Mango, Size: Pack of 6 (8 Fl Oz)
Thanks Amazon for making this drink affordable. I was buying it from Walmart which was pricey. This is my go to drink in the mornings after drinking water. The energy I feel all morning while I am at work. No jittery feeling, I was diagnosed being pre-diabetic. This drink is perfect for me. I get to drink my veggies and fruit.

GREAT GRAPE FLAVORED AND INCREASED ENERGY
Set name: Welch's Grape
I have tried the competitor’s grape flavored versions. This is by far the best grape flavored energy drink. It gives you the increased energy level you’re looking for without making you feel “fidgety.” Highly recommend this energy drink for its effectiveness and flavor!
