The Colnago racing soul triumphs on dirt roads with the Colnago G3-X Shimano GRX 820 2x12, the gravel bike for tackling any type of terrain in any season, designed for riding on dirt and muddy terrain, comfortable even over long distances. The G3-X is made with a carbon monocoque frame and fitted with disc brakes. Plus the chain stays are wide enough to fit tires up to a maximum of 42 millimeters.

The G3-X is equipped with two protective plastic mudguards: one under the bottom bracket and one above the right chainstay to protect the chain from blows. And since longer adventures may require additional bags and bottle cages, the G3-X is equipped with two extra rivet pairs on the top tube and under the down tube.

Horrible quality
Size: 6.5x10ft, Color: Red
Horrible quality. The crank didn't work. The umbrella just flopped open. Once it did I cranked it, but it was cranking in wrong direction. Umbrella sat totally lopsided. The overall quality of this umbrella including the canopy is junk. Looks cheap. Returning!!

Peacock Blue
Size: 6.5x10ft, Color: Lake Blue
Not out yet because of weather, but it looks good, unusual point that some of the spokes according to the directions need to be put on yourself, but at least this way they not bent in box. Note when I bought it - it used the color Lake Blue but the picture was a Peacock Blue - I took the chance and it is a Peacock Blue- I would not call it Lake at all or sky or any of those colors. It worked out for me as it matches perfectly with my Peacock Blue cushions and other umbrellas, It defintiely seems like it is sturdy and the size looks as it should, it has a nice weight as i did open it in house to take a look, the material has a slight sheen which makes it appear a little different than my others, but not something most people would notice.

Attractive and seems like it will hold up
Size: 6.5x10ft, Color: Blue-Green Stripe
Seems sturdy enough. Tilt button is difficult to retract to straight, but maybe just my finger strength, or it will loosen up with time. The color of one of the stripes is off from the photo. I was hoping it was turquoise as shown in picture, but is actually a much deeper blue. Doesn't coordinate with my other patio colors like I hoped it would, but it will do.

Would recommend
Size: 6.5x10ft, Color: Dark Blue
Love the rectangular shape, it allows more coverage in areas that I need it. The tilt feature works well and is handy. Easy to put together and would recommend
