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. |

One of my favorite Sunscreens
Style: SPF 30, Size: 3 Fl Oz (Pack of 1)
This sunscreen is great. When applying, I am very pleased at how easy it is to spread and soak into my skin. It also stays on during the day and also whenever I get in the water. I love the smell as well.

Item As Described
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
Great product. Smells like the beach. The only thing I dislike about it is that it didn’t have a safety seal.

GREAT FOR ADULTS TOO!
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
This isn't just a great sunscreen for kids, it also works great for adults too. I've used this on my face under my makeup for years and it doesn't make me break out. I've tested many facial sunscreens and none of them go on as smoothly as this one. A lot of them aren't moist enough to spread out on the skin, but this one is very moist and I don't need to use a lot of it for coverage. Facial sunscreens can be pricey, but this Kids Sunscreen is under $10 and is a great value. It has a subtle, delicate scent and that's another plus for me. When it's on my face, I don't notice it. I avoid overpowering scents in all my facial products.

Moisturizing, effective, pleasantly scented sunscreen
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1), Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
This is the go-to sunscreen our whole family has been using for years. It feels moisturizing (but not greasy) and is easy to rub in to avoid any kind of chalky, white residue. The scent is subtle and pleasant, not the strong pronounced sunscreen smell that a lot of others have. Best of all, it is effective! The bottle received is different than the one pictured on Amazon, but we’re not buying it for the bottle, so that’s okay. :) Would recommend.
