Mountain Gravel

The front range foothills town of Nederland, Colorado is named after a Dutch mining company that operated the Caribou mine in the late 1800s. Funnily “Nederland”, or “Netherlands” in English, means low land. The town was given this name because it sits almost two thousand feet lower than the high elevation mine and was a better place to mill the mined ore. The town has also been throwing a gravel bicycle race since 2021, and there is literally nothing “lowland” about it. The main event is the 70 mile Tungsten Course, named after a nearby ghost town and once prosperous mine, and is a beast of a ride featuring 8,000 feet of elevation gain over an absolute roller coaster ride of various terrain including hellishly steep grades, washboarded descents, rocky singletrack, rockier double track, breathtaking views and cool mountain air. It is truly “mountain gravel” at its pinnacle.

Fellow Alchemist Ryan Bennett and I signed up and raced the Tungsten course together, although I use the term “raced” a bit loosely.
The race started at 7am which always means not ideal sleep, an early wakeup, and trying to cram in hurriedly made coffee and a snickers bar on the drive to the start, listening to the Tour de France stage commentary to get hyped up. Bennet met me at the starting paddock and we agreed to hit the start hard and hang on the the front of the pack up the first paved climb out of town and onto the gravel. Our strategy worked great, as we pinned it out of the gate with the lead group and got ahead of 200 or so riders so we had mostly open roads for the first fast gravel descent. At the bottom of this first section there was a short bit of probably the only flat road on the whole course before climbing up Sugarloaf mountain and the southern part of the Switzerland Trail, which is an old rail road grade that used to service the mines as well as provide tourists transportation to the incredible views of snow capped peaks and green valleys all around us. The grade is never that steep, but the terrain is so rocky and rough that it might as well be as you bounce along through puddles and over rocks, crisscrossing the double track looking for the perfect line.

Fortunately the race was spread out by this point so it never felt crowded or intense, just a long solid grind, which turned out to be the theme of the day. At the top of this section was a road climb followed by a short gravel climb, a rolling downhill, and a wickedly steep washed out downhill on Sawmill Gulch. This would be really sketchy in a bunch, but was okay to take cautiously. My race rig also features a dropper post, so using that along with the magical stopping power of modern disc brakes got me safely down the gnar. A looooooong road descent and the only real recovery of the day was followed by some slightly sketchy single track and then some wicked steep switchback ascending up Sunshine Canyon led us to the first rest stop. I got dropped off Bennet’s wheel on the Sunshine steeps, and I rolled into the aid station at Gold Hill to find him eating bacon and being prodded to do a Fireball shot by the Sram support crew. I already felt pretty bad, and figured why let him suffer alone. Fireball, skittles, water bottles topped off and we were on the move again. More ripping descents, more hour long grinding slogs uphill fighting cramp pain and not being able to hold anyone’s wheel eventually led us to the next aid station, where our arms where twisted into drinking more Fireball. My legs had never hurt this bad before, but I could somehow keep pedaling, so how could this make it any worse.
Loaded up with water for the last climb, I got dropped before the climb even started. Bennet had graciously or foolishly waited for me on every hill until now, so I grinded on alone at a snails pace, trying to will away cramps (didn’t work) and just keep grinding. Over the last hump and down one more ripping descent back into town and the finish line, cheered on through the chute by my amazing family and friends hollering and ringing a cowbell. I survived! And lucky for me, the post race had a sweet festival atmosphere with bands, food trucks, beers and vendors displaying their wares. The highlight for me was my 18 month old daughter clapping for me at the finish line, followed by ice cold water and mini Cokes provided by the race organizer. Last, but certaintly not least was the Alchemy crew set up under a big tent to greet us with Colorado Kool-aid for a job well done, or, I guess a job done to be more accurate.
cheese!
As I write this a week later, my legs still hurt, my bike is still dirty, and I can not wait to sign up again next year! See you on the start line!

2016 Best Mountain Bike – NAHBS

Bike Radar by Nick Legan
At the North American Handmade Bicycle Show, a convention hall is filled with bikes that represent the pinnacle of cycling ingenuity and craft. Here, the job of picking award winners is not an easy task. But each of the past four years I’ve had the honor and the chore of doing just that, helping to judge the beautiful bikes on display at NAHBS. This year several categories were especially tough, in which case the judges’ panel decided to include Honorable Mentions.

The People’s Choice winner was Alchemy Cycles for its Arktos full-suspension bike:

 

The Carbon Fiber Advantage for Full-Suspension All Mountain Bikes

Carbon fiber, carbon fiber, carbon fiber…These days, carbon fiber is ubiquitous. Everything from the wings of Boeing’s famed 787 Dreamliner to that iPhone case in your pocket utilize the material. And with good reason. Carbon fiber allows manufacturers to produce high-strength parts that are extremely lightweight and durable. It’s also the ultimate material for bicycle frame construction. That’s why we produce each full suspension all mountain bike with carbon fiber.

Carbon Fiber: Lightweight and High Strength

When Boeing set out to design the Dreamliner, they had lofty goals. They wanted the airplane to achieve much higher fuel efficiency standards, while carrying the same number of passengers and going even further distances. They realized quickly the solution was to make the plane much, much lighter. But reducing weight typically means using less material. When flying at 40 thousand feet with 300 plus passengers, it’s no time to throw caution to the proverbial wind. The solution Boeing landed on was carbon fiber. Now, over 50% of a Dreamliner uses carbon composites.

Carbon Fiber Mountain Bike Designs

Like the Boeing’s engineers, Alchemy’s designers also have lofty goals. Reducing weight improves a full suspension all mountain bike’s efficiency. But we can’t only consider weight, as reducing strength in our design would mean disastrous results for the rider. Getting a high strength-to-weight ratio is the key, and carbon fiber delivers that magic formula. It’s 70% stronger than steel, and 40% stronger than aluminum at the same weights.

How We Use Carbon Fiber in Our Design

How Alchemy uses carbon fiber to build a full suspension all mountain bike is equally important. Alchemy Bicycles has over ten years of experience hand-building carbon bikes in Denver, Colorado, and it’s given us a leg up on the competition. Take a close look at our mountain bike frames, and you’ll see the fibers orientated in a specific direction. We use a bi-directional technique to optimize the carbon’s strength without excess material and added extra weight. And our experience and proprietary lay-up techniques have earned us accolades from riders and industry alike. Each Alchemy frame starts with the base carbon material, in the case of a full suspension carbon fiber all mountain bike like the Arktos, something commonly called prepreg. Prepreg is a sheet of carbon that is impregnated with a resin that acts as a curing agent during the molding process. Alchemy is unique in that each new mountain bike we create is prototyped in the US, and we determine the process by which we cut and apply the prepreg material to make the frame (called the lay up schedule). This is one of the key steps in optimizing stiffness and strength.

The Cost of Carbon Fiber

Mountain Bike Hall of Famer Keith Bontrager is famously quoted as saying, “Cheap, light, strong…pick two.” This maxim applies to building a full suspension carbon fiber all mountain bike. With the Alchemy mountain bikes as an example, we’re able to produce one of the lightest, strongest frames on the market. But like all carbon bike frames, it comes with a price. The base carbon material can be as much as 10 times the price of other materials. And it’s not just the material. There are no magic robots tossing together carbon frames in split seconds. Every full suspension carbon all mountain bike is handmade, by real people in our warehouse laboriously taking CNC-cut pieces of prepreg material to make a frame. We also start with only the best high-modulus prepreg sheets, made by Mitsubishi in Japan. Using quality carbon ensures that the resin and carbon are consistent through the base carbon sheets. Today, it’s hard to imagine not having a full suspension all mountain bike made with carbon. The benefits are too numerous, and the sport and riders are evolving at the same clip as the bicycles themselves. Carbon allows Alchemy to optimize the strength, weight, stiffness, and durability of our designs, and produce a bike that is capable of pulling off things that that would have been unimaginable even 10 years ago.
