Fancy cross-country mountain biking? Want a waif-like carbon steed to help you to a step on the  podium? But you do not want to spend a crazy amount to make this happen? We have built you your dream frame then. Our M17 carbon fibre XC mountain bike frame is just for you.

We have used aerospace grade carbon fibre to make sure that the ride quality of the M17 frame is out of the world. We also know that even if a frame is comfortable that alone will not win races, so we have worked hard to make sure the frame is light and super stiff where you need it to be stiff. We even made sure that your cables stay hidden through our internal routing.

To create a more substantial bottom bracket area we have used a BB92 bottom bracket shell. This gives our engineers more space to play with and look at the size of our chainstays, and down tube, your pedaling effort will not be flexing ant of these carbon tubes. Our chain stays run all the way to a 142 x 12mm rear thru axle, meaning your wheel will have no room to move it will be held tightly in place.

The downtube mates up with our tapered headtube, you will have no problem finding a fork to fit this XC beast. This frame will then go precisely where you point it, and it will not let you take B-lines you will be A-line through all the courses. Our carbon seat stays, and top tube though are designed to help manage the stiffness from below and cancel out any vibrations, adding a bit of vertical compliance to your ride.

Comfortable and Supportive, but Adjust the Filling
Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.
