The Great Divide Mountain Bike Route (GDMBR) is a cycling adventurer’s dream. The route travels 2,747 miles from Banff, Canada to Antelope Wells, NM through the Rocky Mountains, criss-crossing the Continental Divide and some of the most beautiful terrain on the planet. After months of training and planning, and nearly a decade of dreaming, I set off to complete the GDMBR on June 22, 2019 on my trusty Mahall stead. Through this series of posts I will discuss some of the highlights of the journey, my gear, and bikepacking tips for those looking to set off on their own epic adventures.

A Friendly Face in Whitefish, MT

I was excited to get moving on the morning of June 25th, day 4 of the journey, because part of the day would be spent in Whitefish, MT with my friend and framebuilder, Mark Hall. Jeremy and I had spent the previous night at Tuchuk Campground, just west of Glacier National Park in the Flathead National Forest, after completing our first century of the trip. My excitement was chilled as I emerged from my bivy and felt the 25℉ air on my face, and my fingers were not thrilled about packing up and pumping water from the nearby stream. Besides the chilly start, it was smooth sailing on the ~60 miles from Tuchuk to Whitefish, during which we were treated with incredible views of mountain ranges within Glacier, a lovely lunch stop along Red Meadow Lake, and a sweet gravel downhill from the lake that extended for nearly 20 miles. Not long after I hit the pavement I was greeted with shouts from a passing car, and it was none other than Mark tracking me down to dish out beer and bananas!

The hospitality did not end there. Mark and his wife Shari had planned a stay at a friend’s vacation home in Whitefish around our GDMBR timeline (no complaints from me about a roof over my head and a cozy bed!). As we arrived the drool-inspiring aroma of a hearty pasta sauce was in the air, so Jeremy and I made quick work of laying out our wet gear in the sun and showering so we could enjoy a delicious, home-cooked, protein- and carb-filled spaghetti and salad dinner. After filling our bellies Mark brought us into town to resupply, check out downtown, and imbibe local beer and whiskey. When we returned to the house for the evening Mark and I made the short walk down to a dock on Whitefish Lake, where we enjoyed chatting about the trip, a lakeside beer, and a lovely sunset over the lake. This moment on the dock had me reminiscing about the beginning of our friendship, which sprouted along with the lovely Mahall frame that I was riding on the trek…

The Birth of Mahall 015

When I started dreaming about the GDMBR over a decade earlier I never gave much thought to the bike I would ride. I got more serious about the trip in 2016, thanks in large part to improved fitness riding with a band of Hooligans in the Tri-Cities of Washington (including Damion from the previous post). Thinking more about the bike I wanted to ride, I realized that bike did not exist. I reached out to Mark with my dream bike wish list in July 2016. From this point forward, I had the best time working with Mark to take the bike from a dream to a reality. Mark was exceptionally responsive to my messages and ideas. I think what I absolutely loved the most about working with Mark on this frame is his willingness to push the boundaries of his framebuilding to meet the needs and desires of his clients. Prior to this bike, Mahall 015, he had never built a belt drive compatible bike or one that had equivalent front and rear axle spacing. He worked tirelessly with Gates Carbon Drive to design and build the bike around their drivetrain and with Ti Cycles in Portland to bring my 142×12 spaced fork to life.

With Mark, the service does not end when the bike leaves the shop – he ensures that his clients are 100% satisfied at every stage of the process from design through application. When there were issues with the belt “ratcheting” (slipping on the sprockets) Mark was quick to work on a solution to the problem with both myself and Gates. To this day I still work with Mark when it comes to this frame and its components, and he has done countless other modifications to the other bike frames in my garage. I always look forward to time spent in the shop enjoying a pint and discussing the next adventure. I cannot recommend Mark enough for the cyclists out there thinking about dipping their toe into the custom bike world – you will not be disappointed.

Next up!

Cap the Climax Stagecoach Odyssey:

Building America’s Wildest Gravel Bikepacking Route


America’s Most Rugged Gravel

– – – – X

I’ve been cycling across Oregon’s rugged backcountry in search of stupid for some time now… Stupidly steep, stupidly technical, stupidly beautiful, stupid that somebody calls this a road, and stupid fun.

Eric Hoberoth, owner of Ren Cycles summed up my route selections best:

“Terrain that is more the idea of a gravel road than it is gravel or road. Most of the miles land in between challenging but never impassable; loaded with interesting vistas, dotted with livestock and wild animals, pitched at varying grades, and susceptible to the occasional rapid and dramatic change in weather. All of it runs through alpine forest, intermediate scrub, grassland, desert, and pasture that seems to spread off into the distance in every direction forever.”


When I first moved to Prairie City, Oregon (population 500) I was frustrated with the lack of singletrack. The nearest place to ride mountain bikes was Boise or Bend, each a 300 mile round trip away.

Desperate for backcountry riding, I got my hands on a map of the decommissioned US Forest Service roads in the Malheur National Forest. I quickly discovered I was sitting in one of the Nation’s greatest untapped treasure troves of cycling.

Eastern Oregon has tens of thousands of miles of gravel and natural surface “roads.” Most are now more like paths and cattle trails than anything else. Old ghost towns, timber sales, and mining sites dot the landscape and while the industries and its workers are long gone, the access to these places remain, connected by a seemingly endless network of decommissioned roadways.

I became obsessed with connecting them into rideable routes, slowly stitching them together with the most absurd terrain I could find. I was always on the hunt for some extra little piece of brain-candy here or there: a mine, an overlook, a change from brown dirt to red, a hotspring, a fire lookout tower you could sleep in. Some of these rides grew into Ride with GPS Ambassador Routes, now available to the public on their website.

It’s now been four years since my first forays into Eastern Oregon’s rugged backroads and they’ve changed my approach to cycling for good. These landscapes made a gravel believer out of me. Today my collection of multiday ambassador routes is substantial, and I’ve started plotting something absurd: a mega-route linking all my multiday routes together… A gravel odyssey to cap the climax.


A demanding, epic, amazing, scenic, tough, well-planned ride on the edge of nowhere.

From Boise to Burns

– – – – X

I moved away from Oregon two years back to return to my first cycling love: Alaska, but I am still drawn to Eastern Oregon’s endless roughtrack. I’ve made a habit of returning each June to work on my gravel odyssey and attend the Skull 120 Gravel Grind, in Burns, OR.

This year I intended to knock out most of the missing pieces of my mega-route in one massive, 500 mile, 35,000 foot gain, 10-day push from Boise to Burns. Other than the roads leading out of Boise, the entire route traveled gravel perfectly suited for a lover of the absurd.

When we rolled out of Boise we had to carry every tool and calorie we would need for the journey. This expedition was to be completely self-sufficient. The only signs of civilization along the entire route would be two tiny gas stations. We would encounter these as we crossed the only paved roads we saw among the unending gravel, mountains, canyons, desert, and prairie. More difficult still was carrying the 13 liters of water needed to pass through the arid landscape. All said, my loaded Mahall Bikeworks gravel rig weighed in at 117 pounds. This would be the heaviest I’ve ever loaded a bike, and the hardest I’d ever pushed myself.

Entire days went by without seeing another human being. One of the few people we did meet was a rancher, named Kent. He didn’t mince words when we rolled onto his ranch:

“You’re a couple of damned fools. Nobody’s ever

pedal-biked across these lands. Damned fools is what you are.”

The landscape dished out all manner of weather: punishing heat, snow, wind and rain. The tracks were diverse in their brutality. They seemed to seek some fiendish way to puncture a tire or dent a rim at every turn. Alongside the hardships, in robust turnout were landscapes to boggle-the-mind. Every day I found myself muttering ‘this is the most amazing place I’ve ever ridden’.

As far as bikepacking route scouting expeditions are concerned, this trip was pure gold. It was as though our bikes had the Midas Touch. Every new direction led to exciting discoveries. And we never got shot at – not even once! While some may take that as a given, it has happened to me on more than one occasion. Public access easements across private land are common in this part of the world, making our route completely legal… But when nobody other than you or your family has stepped foot on the land in generations, such laws seem to be forgotten.

With this year’s adventure to Burns a monumental success, the completion of the Cap the Climax Stagecoach Odyssey feels closer than ever.

Bikepacking on Only 24 Spokes!?

– – – – X


I started riding Rolf Prima wheels this spring with the Alsea+ 24 spoke paired midfat wheelset after my friend Mark Hall, owner of Mahall Bikeworks recommended the Rolf Prima line. I’ll admit I was more than a bit skeptical. My cycling focus has always been on bikepacking and deep backcountry exploration. I’m no weight weenie, and I push my gear hard. Given the remoteness of my adventures, I put durability as the top requirement of all my cycling purchases.

I’d found the Alsea+ to be a joy to ride, and incredibly robust, as I tested their mettle throughout the Spring, but they’d seen nothing as arduous as this journey. As my Oregon expedition approached, I was in need of gravel wheelset. Rolf Prima, sponsor of the Skull 120 offered some new gravel products for testing during my June expedition. I hesitantly agreed to tackle this already intimidating ride on the Hyalite 25 – a paired spoke 25mm internal gravel wheel designed with these sorts of adventures in mind.

My prior gravel wheelset was quite different. Heavy and robust, its high spoke count and weight gave me confidence in their strength, but added little to the joy of my ride. I was happy to shed some weight and roll a bit faster, but it was difficult to imagine how a 24 spoke gravel wheel could possibly meet the demands of a 117lbs gravel bike traveling over seemingly endless rock gardens and cattle track. Knowing that Rolf Prima hub internals are machined in the USA with titanium bits by Rolf Prima’s production partner – White Industries, one of my personal favorite brands – set my mind at ease hub-wise, but the spoke configuration still had me guessing. As we rolled into the hills outside of the Snake River Valley I was wondering what in the hell I had signed up for. My worries proved needless.

During the following ten days, I went from cringing and braking over every big rock to thoughtlessly barrelling down steep grades filled with nasty bits of potentially wheel-killing debris. The 650b platform mated with Rene Herse Juniper Ridge Endurance tread made for the most inspiring trip I had ever executed across these harrowing lands. Though my partner in this expedition would taco his 29er Nextie MTB 36 spoke rim riding the Skull 120 at the end of the trip, the Rolf Prima Hyalite 25 wheels stayed true and strong throughout the entire ordeal, and continue to ride flawlessly as of writing this.

Just a few months ago I would have felt crazy saying it, but after what I put these wheels through, I now fully and unequivocally endorse the Rolf Prima 24 paired spoke technology. If the Hyalite 25 wheel can survive the punishing slog and brutal load I subjected it to, I have full faith that it will be a great wheel for anyone.
