Pick your line and let it rip. From chunky alpine terrain to warp-speed park runs, this hard-charging 29er feasts on rugged terrain, giving you the confidence to charge harder.
Race-bred suspension
Maestro rear suspension and a 170mm fork developed and tested in Enduro World Series races. The trunnion mount rear shock has a longer stroke and smoother feel, and an Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight.
Progressive enduro geometry
A strong and durable ALUUX SL aluminum frameset helps you ride aggressive descents and rail corners with confidence. Enduro-optimized head and seattube angles, plus a 170mm fork with 44mm offset, produce confident front-end handling.
29er confidence and control
Larger 29-inch diameter wheels roll over rugged enduro terrain with improved balance and stability, giving you the momentum to crank up tough climbs and the confidence to fly on fast, technical descents.

| Front Derailleur N/A | Weight The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality. |

Very good
Size: Standard (Mid Loft), Number of Items: 1
Excellent pillow. Soft but medium support. Fell asleep on it right away and it stays cool. Like sleeping on a cloud.

A Good Night’s 💤
Size: Standard (Mid Loft), Number of Items: 1
I’ve bought many pillows over the years and this pillow is by far the best for me. I am a back and side sleeper. Finally wake up without a headache or neck discomfort. I bought the medium standard. Just the right consistency. Not to soft not to firm. Stay cool pillow.

Confortable
Size: Standard (Mid Loft), Number of Items: 1
Excellent support. Always fluffy. It does have a smell but as recommended I let it air out for a day. I also washed the cover and had no issue.

Perfect latex pillow
Size: Queen Size
I’ve been using the pillow for about a week, and I’m really happy with it so far. It’s soft and bouncy but still gives enough support for my neck, which is hard to find in a pillow.
When I first received it, there was a slight odor from the new materials, but it went away after about two days, so it wasn’t a big deal at all.
What I noticed right away is how it kind of molds to your head and neck without feeling too firm. It’s definitely more supportive than regular foam or down pillows, but it’s not stiff at all. I also like that it stays cool throughout the night—I never wake up feeling overheated.
Overall, it’s a solid choice if you’re looking for a pillow that’s soft but not too soft, with enough support to keep your neck comfortable. Definitely worth trying if you’re picky about pillows like I am.

Our favorite pillows & we're picky!
Size: Queen Size
My whole family love these pillows, & we are picky pillow people! They are comfortable through the whole night & I get the best nights sleep. We even put them in our AirBnB house & guests ask where they can buy one. I highly recommend. They are soft on your head but still supportive.
