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.

Pieces missing, poor instructions, would not buy again!
Let's start with the good news: I did, eventually, get the shelves hung after a trip to the hardware store and some trial and error. Now for the bad news: * One of the screws holding the brace to the shelf was missing, making the shelf wobbly before I even hung it. * The directions for hanging the shelves show a different anchor than the one that comes packaged with them. This anchor will ONLY work in sturdy drywall and it's going to leave a huge hole behind. * The directions tell you to flip the shelf upside-down to position and mark the screw holes, BUT that means the sides of the shelf are reversed, and the hole positions do not match on each side. So if you start hammering or drilling based on those marks, they don't align and now you have extra holes in your wall. Honestly, I regret buying these and wish I'd just chosen a free-standing shelf instead. But I made it work for me, so I guess there's that.

Nice oak corner shelf but check your measurements first
5 stars for the shelf, 3 stars for myself :-) This is a well-made oak corner shelf that looks great where I put it. The wood is nice quality and the construction is solid. Before you order though, do yourself a favor and check two things: 1) Make sure the size is actually big enough for what you need, and 2) Check that your corner is actually a true 90-degree angle. Turns out mine isn't perfectly square and now I'm trying to figure out how to position this thing properly. Good product overall, just wish I'd measured more carefully before ordering.

i’ve been wanting this shelf for quite some time and finally decided I’m doing it. I’m absolutely completely satisfied with the size the quality of the wood and the paint job. It’s made very well. I have to say I was surprised at how nicely sanded it was and ready to hang.
