Danielle Bordeleau

Growing up on Vancouver Island it was inevitable that Dani would find herself following a passion on two wheels. Fast forward to 2017 she made the move to Whistler where her passion grew. You can now find her pushing her limits, throwing sick whips and going big in the bikepark and most recently joining the women’s freeride scene as a digger at Redbull Formation.

Raimundo Guzman

Raimundo Guzman is a professional mountain biker who lives to ride, Rai doesn't care about the trail as long it's on the way down — he will have fun! Rai found a whole new world when he jumped from BMX to MTB at 25 years old. His first ride hooked him for life. Rai packed up and moved from Chile to Canada with nothing but hope and a big dream to become a pro rider. Since then, he’s been racing at events like Crankworx and the DH World Cup. "Mountain biking completely changed my life, and I believe it can also change others,” he says. "I blend riding with storytelling to inspire more people to grab a bike and live this lifestyle!” Rai started mountain biking as an adult (25) and living the dream traveling the world with his bikes led him to another passion, helping others achieve their dreams too. Combining that with Rai's background as an industrial engineer is how his business was born. "Now, I ride bikes and help others for a living,” Rai said.

2026 Activities:

  • Crankworx Whistler, British Columbia
  • Local DH races in British Columbia
  • UCI Pumptrack Worlds 2027 (TBD)
  • UCI DH Nationals in Chile

Favorite Trails: I do not have a favorite trail, I like them all as long as they are on the way down!! I'm not picky and for me it's super easy to have fun — But if I have to choose I’d go with Hot Tuna, Wu-Tang and Gouranga.

Delium Tires:
Honestly, I’m excited by how reliable Delium Tires are. I haven’t had a flat or ripped tire in two years (knocking on wood right now!), even in the gnarliest races and conditions. That’s priceless for me — not having to stress about flats means I can just focus on riding hard and having fun. I fully trust these tires, especially the Rugged Reinforced. I run them front and rear on both my DH and Enduro bikes. Sometimes, if the weather calls for it, I’ll throw a Versatile on the rear, but the Rugged is my favorite!

Thomas Bjelic

Originally from Toronto, Ontario, Tom currently resides in Las Vegas and works as a Professor in the Department of Film at UNLV. He got his first mountain bike in 1985, a fully rigid, friction shifting, cantilever brake mounted Norco Sasquatch. He managed to break the frame 2 hours into his first ride. After a long walk back to the shop, they offered him a better bike and a part time job to help pay for it. And so began a life-long obsession. After living through the purple anodized craze of the 90’s (it’s back!) and the early years of suspension evolution and still being alive to talk about it, Tom’s main rides now are a Pivot Trail 429 Enduro (29), a Yeti SB160 (27.5) and an Alchemy Arktos 150 (27.5). His tire of choice is the Delium Rugged Reinforced for its maximum traction, durability and value. Gooseberry Mesa in Hurricane, Utah ranks as his all time favorite trail with Kingdom Trails in Burke Vermont and Tsali/Dupont State Forest in North Carolina rounding out the podium. A strong coalition of cycling advocacy groups and a thriving MBA chapter has resulted in an excellent variety of trails in the Las Vegas valley. His favorite local loop up Flow Job and down Ebb and Flow has enough vertical to keep you honest, enough flow to keep you smiling and enough air time to pray for a good landing. He often describes the trails in Vegas as something akin to riding a dried-out bed of coral. And he has the scars to prove it. A durable performance tire is essential for control and longevity on the sharp, rocky Vegas trails and Delium handles all of it.

Colin Burgess

After traveling extensively throughout the US with his family, Colin landed in the mountains of Eastern Tennessee and currently calls the city of Chattanooga home. The vibrant outdoor lifestyle, supportive cycling community, and year-round access to trails started Colin’s cycling journey, but an Enduro race in Dec 2020 on a friend’s borrowed bike, ignited his passion for gravity racing. He is stoked to be part of the Downhill and Enduro scene of the Southeast, racing for Huck and Braaap Cycling and for his college King University. He is also currently helping to coach and mentor the Junior Enduro racers on his team. You will catch Colin riding the large variety of trails that the Southeast has to offer or between the tape at a race.

Sasha Yakovleff

My name is Sasha and I'm a freeride MTB athlete originally hailing from New England, USA. These days, my family splits our time between Utah, New England, and Canada. I'm fully addicted to riding all kinds of DH/trail/dirt jump bikes, in any weather, on any terrain, any time of year, anywhere we go. I seem to love riding more every day, somehow, and I hope that love continues to grow as long as possible. Trail building is a big part of mountain biking for me: envisioning something, building it, riding it, and then sharing it is a holistic and creative process that motivates me. I'm pumped to partner with Delium for the product and its value! Their MTB tires are both amazing and affordable — I can't wait to see where my Delium tires take me next!

I love the feeling of hitting big jumps, blasting through‬ the bike park, and railing corners. The mountain bike community is always something I have felt‬ connected with, digging new trails, sick sessions with all my friends, and sharing party laps are‬ all something that is special to me. I actually learned to ride a bike when I was only 2 years old!‬ Some of my goals are to race internally at a professional level and travel the world with my bike!‬
