Summer is flying by! One of the nicest Alaskan summers I can remember! 🙌

The program has been busy, but simple. Family time, trail work, yard work, riding. Repeat till the sun goes down or it starts raining, whatever comes first!

Got to visit another land of midnight sun for a solid mountain bike adventure with a killer crew. The land of fire and ice delivered some harsh weather, epic landscapes, and impressive nuggets of trail 👌
Always a special experience going to a new spot.
Thanks for the local knowledge and photos @leifurh94 👊

Busy last few weeks during this temperamental Alaska winter. Never a dull moment.
Green grass and flood warnings in January, followed by a deep freeze. (Little too close to NH winter vibes) Family ski time, balls cold ski tour (worth the frozen stache) , house projects, friends and family heli time, and just like that it’s February and the sun is back 😎 by @postroski

2025 season has begun. Maybe we’ll get snow to sea level here soon. Until then, let the alders be your friends.

Also first real ski day in the new @blizzard_tecnica Zero G Tour Pro boot. Little lighter, slightly more progressive flex and standard “kinds feels like a resort boot” Zero G downhill performance. Nice upgrades I’d say.

I’ve been trusting @shimanomtb on my bikes for the last fifteen years. Between the tape racing and on the deepest adventures. One standout aspect of the XTR/XT groups that I think separates it, is the reliability and ride feel you can trust. I’ve learned it from racing, but now can trust it deep in the backcountry, like on our Alaska trip this summer. We were all running XT/XTR for 10 days in the Alaska backcountry without any thoughts towards tinkering with our bikes.
And Kyper approves, now that she can pull the break levers!

One month away from winter solstice and we’ll take the warm sunny inversion! 😎 Nice opener amongst the glides and low tide.
