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. |

A Must-Have for Sensitive Skin
Size: 5 Fl Oz (Pack of 1)
recently tried La Roche-Posay sunscreen and I’m really impressed! 🌞 The texture is lightweight, non-greasy, and absorbs quickly without leaving a white cast, which is a big plus for daily wear. It feels gentle on my skin and doesn’t clog pores, making it perfect for sensitive or acne-prone skin. I also love that it provides strong, broad-spectrum protection while still feeling breathable. Overall, it’s become my go-to sunscreen—I actually enjoy applying it every morning because it feels more like skincare than sunscreen. Definitely worth it!
I would be honored if you would consider me to receive a PR package. I’d love the opportunity to try more of your products and create authentic content that highlights the benefits of La Roche-Posay skincare.
Thank you so much for your time and consideration!
Warm regards,
Andrea Mohanlall

It feels very good on the skin.
Size: 3 Fl Oz (Pack of 1)
I’ve been using this sunscreen for about a week now, and honestly, I’ve liked it even more than I expected. The skin on my face feels much softer and healthier, and one thing I’ve definitely noticed is that my dark circles are gradually looking a bit lighter and less tired. I love it because it doesn’t feel heavy, absorbs quickly, and doesn’t leave a greasy residue.
I also like that it works well under makeup or just on its own for everyday use. For now, I’m giving it 4 stars because I haven’t been using it for very long yet and want to see more results, but so far, I definitely feel a difference in my skin. If I continue to see more positive changes, I’ll come back to update my review.

Blends nicely, is not greasy.
Size: 5 Fl Oz (Pack of 1)
Light, blends nicely into skin. Does a good job of blocking the sun. I will buy it again before the summer is over.

Feels like nothing!
Size: 3 Fl Oz (Pack of 1)
Fantastic! I never write reviews but this is incredible. Just as advertised it dries quickly, doesn’t feel oily and doesn’t leave marks. And the coverage is no joke in this AZ sun! Held up during Memorial Day weekend at the pool all day. Excellent all around!
