New on the blog: Featured Rider Spencer Kessler.

We spotted a few Tumbleweed riders in BIKEPACKING.com’s coverage of the rigs of the Tour Divide this year. Among them was Spencer Kessler’s Midnight Sparkle Stargazer, affectionately named Ursa.

In June, Spencer rode the GDMBR northbound as a tour, not a race, covering 2,100 miles of the Rockies at a pace of about 50-60 miles a day. After he wrapped up his tour, we reached out to hear how it went and he generously shared his photos, thoughts on the build, the route, and what his self-supported tour was like.

Spencer’s a self-proclaimed bike nerd who tends to place reliability above most other factors. He felt confident that his Stargazer would be able to handle whatever was thrown his way–and man was he right.

Here are his bike’s specs:
Bike: Tumbleweed Stargazer, gen 1, Midnight Sparkle
Drivetrain: 1×12 combination Shimano GRX 820 and XT mechanical. 10-51T cassette, 32T chainring. Swapped to a 30T Wolf Tooth oval on the CAMO system.
Wheels & tires: Alloy DT Swiss wheels, 350 hubs. Vittoria Mezcal, 2.4″ front, 2.35″ rear.
Bars: Tumbleweed Big Dipper
Saddle: WTB Volt
Pedals: Shimano PD-M8100
Seatpost: Started rigid, swapped to a PNW Coast Suspension Dropper

Head to the blog for Spencer’s full story, photos, highlights from his build, and a piping hot take.

We have a bunch of new merch that will be on the webstore this evening, all with artwork by Kyler Martz. 26oz water bottles, Comfort Colors pocket tees in black, olive green and blue, and bandanas in brown and turquoise (printed in Portland by Spencer Curtis). We also have stickers and matchboxes that are included in every order. Kyler designed our first bandana about a decade ago and we are super happy to be able to collaborate with him once again! Supplies are pretty limited, especially for the T shirts.

We’ve been getting a lot of bikes out the door this summer but haven’t been doing a great job shooting photos of them all. This one is an XM Stargazer in Steel Blue with some really nice silver accents. It’s mostly a standard build spec with 12 speed fully mechanical brakes and shifting, a rarity in modern drop bar bikes. The customer opted for a set of polished Big Dipper bars and silver PNW Loam dropper post, as well as a silver headset, stem and seat post clamp. We even sourced some silver DT rims for this build (we build 99% of our wheels in house by hand). This Stargazer rides beautifully and is ready to take on trails and tours with confidence.

Our titanium frames are due to arrive in the next couple weeks, we will have our hands full with builds and shipping out framesets, we have a few still available in some sizes between the three models. We are also taking deposits for an early 2027 production run, get in touch if you’re interested.

We’ve got an update from Madeline, and one thing is for certain: her Sunliner is covering miles and miles.

Madeline broke in her new Sunliner on a recent journey from Jasper to Banff. 200 miles through the Canadian Rockies, home to more glaciers than you can count. Her sister came along for this preparatory trek, which Madeline treated as her pre-divide training. This trip resulted in that all too familiar soreness settling back into her legs, and excitement for the adventure to come.

Then came the Great Divide, and the first week was full of nothing but surprises. Day one threw singletrack at her before she even knew whether she’d be on dirt or asphalt. She passed a grizzly at a respectful distance, a fair reminder of just how wild this route is, and turned down a lift to escape the big guy, trusting a little sense and some bear spray instead. Slowly the track eased into gravel forest service road and, post grizzly encounter, her confidence came back.

A few more days through Canada and she crossed into Montana, riding into heavy smoke and hoping for a bit of rain to give the burning lands some relief.

Through all of it, the Sunliner has been holding up like a charm on rough roads. That’s the whole point. A bike so dialed you can spend your energy on grizzlies and glaciers instead of your rig.

Give Madeline Hryse a follow to see where the divide takes her. The adventure is just getting started.

Nine wild days in Chile with Daniel Camp as he rides the last stretch of Pacific coast he’ll see before Argentina.

It started at sea level and climbed to the biggest altitude of his trip at 15,000 feet followed by four days through the Atacama, the driest place on earth outside the poles. The road was smooth and empty, and by his account, one of the most mentally taxing days he’s ever spent on his bike. The hours pass and it feels like you’ve gone nowhere. But he’s learned that beauty turns up in every place, mostly in the sunsets and star-filled skies.

The desert kept testing him. Eight liters of water down to nearly nothing before the next source. A stranger’s oasis with mate and fresh-baked bread. Then the Chilean Puna, five days of remote riding, hailstorms rolling in before noon, and lightning close enough to feel static in his hands and face. One night the police and rangers handed him a barn to wait it out. Another he dug a trench around his tent while thunder cracked overhead.

Then, after five days of pavement, he finally hit dirt. All dirt from there to the Bolivian border. Salt flats, hot springs he’d earned, and a smuggler’s route to shortcut the last miles.
That’s the kind of riding these bikes are built for.

Follow Daniel Camp for the next stop on his journey: entering into Bolivia.
