Faster Where it Matters

The Mach 4 SL is XC, distilled to its fastest form—engineered for efficiency, sharpened for precision and built to master the modern racecourse. Born from the crucible of World Cup XC and epic endurance racing, it balances a feathery build with an obsession for stiffness, control and efficiency.

Efficiency Engineered

Built with our highest-modulus carbon fiber, the Mach 4 SL sets a new standard for stiffness-to-weight ratio. A reimagined frame channels every watt into pure acceleration, while updated geometry places you in the optimal pedaling position and keeps handling precise and predictable at speed. On the trail, the Mach 4 SL’s dw-link suspension design delivers instant acceleration out of corners, unwavering traction on steep climbs and the momentum to stay ahead when the pace surges.

XC Evolved

XC courses have evolved, and the Mach 4 SL is evolving with them. A slacker head angle, 120mm fork and refined kinematics deliver composure when the trail gets rough while preserving the bike’s razor-sharp cornering precision. It’s stable when you’re dropping into technical descents yet agile enough to carve corners at race speed.

a good choice
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
Assembled chair only to find that the lift cylinder was faulty. Would have preferred to be able to just get a replacement cylinder but calling China didn't seem like a viable option. Guessing which one & buying it online would involve paying for a good portion of what the chair cost. Customer service could only offer a replacement or refund. We're disassembling (so much fun?!) to send it back. The chair itself was very comfortable, assembled fairly easily and instructions pretty clear. Again, if we could only have asked the seller for the replacement part......**Update**...Or if the instructions that seemed so clear were clearer!, as we started to disassemble, we decided to see what would happen if the tension knob (see photo) was loosened. IT ALLOWED THE LIFT CYLINDER TO WORK. Not at all what the instructions say. At any rate, we're keeping the chair.

This chair is amazing
Color: Sky Blue, Size: Pack of 1, Color: Sky Blue, Size: Pack of 1
⭐⭐⭐⭐⭐ Absolutely love this chair! It was super easy to assemble—I had it set up in no time with clear instructions and minimal effort. The comfort level is fantastic; the seat cushion is just right and the back support makes it great for longer sitting sessions. The color is beautiful in person—clean, modern, and adds a fresh pop to the room without being overwhelming. I also really like the smooth wheels and sturdy build; it feels stable and well-made. Overall, this is a great combination of style, comfort, and value. Highly recommend!

Great Chair! Worth the Price!
Color: Sky Blue, Size: Pack of 1
LOVE my new desk chair! I got the Sky Blue which is a really pretty blue in person. I work from home in tech, and had been getting constant headaches no matter what position I was in. I finally decided to invest in a better desk chair, and I'm SO glad I did! It's much more supportive and comfortable. I really like that I can flip the arms up or down, and the height is easy to adjust. Also, because I can flip the arms up, I can keep the chair out of the way when I'm not working by putting it right up against the desk. Very much worth the price! Assembly was simply and quick. Not even 30 minutes. Also, when I had a question about the chair, their support team was quick to respond and very helpful. Highly recommend!
