FatBack is Wired Gadget

Alaskan Snow Bike Rolls Into Sunny California

MONTEREY, Calif. -- Alaskan biker Greg Matyas' Fatback snow bike has huge fat tires and a unique banana-shaped top tube that slopes down in the middle.

The tires are designed for snow and so is the top tube: it slopes to stop you whacking your privates when you step off the pedals and sink into the snow.

"It's saved me many times," Matyas laughed.

Matyas got a lot of admiring looks and 'Cool!' comments as he rode his Fatback bike around the Sea Otter bike show.

Based in Anchorage, Alaska, Matyas custom builds Fatback bikes for customers, some of them who ride on soft sand as well as snow. The bikes start at about $3,000.

"You air down a little bit and it rides better than a full suspension bike," says Matyas, who rides his bike in Alaska year round.

"It's way more fun than staring at the TV," he says. "We have underground race series all year long. After the races, we hang hot around the fire like a bunch of homeless guys with $4,000 bikes. There's a magic to being out in 30 below."

Iditarod Trail Invitational on VELO

VeloNews

Snow machine: Jeff Oatley's Rig for the Iditarod Trail Invitational

One of the most famous and unique endurance races in the world takes place annually in Alaska. The Iditarod sled dog race was won on March 18, when Alaskan Lance Mackey reached the end of the 1049-mile route from Anchorage to Nome in nine days, 21 hours, 38 minutes and 46 seconds. The last finisher came in nearly six days later.

A separate but similar race pits self-propelled competitors against each other on the same route as the Iditarod. The annual Iditarod Trail Invitational (ITI) is limited to 50 racers, who may choose a mode of travel (bike, ski, or hike) and a race distance (350 miles to McGrath, or 1100 miles to Nome).

VeloNews had the opportunity to talk with ultra-endurance rider Jeff Oatley, winner of this year’s 350-mile ITI, about the equipment needed for the event.

The RaceThe 350-mile ITI begins in Knik, Alaska and follows the Iditarod Trail to McGrath, which took Oatley five days, 19 hours, and 34 minutes this year. As you might imagine, the preparation is unlike that of pretty much any other race out there. Extreme cold, snow, ice, and variable trail conditions place unique demands on both the bike and rider.

The most important concern for any competitor of the ITI is safety, which means readiness for the harshest weather that Alaska can dish out. “The thing about the ITI is that it demands a much larger skill set than any other race I know of,” said Oatley, “It traverses the Alaska Range in the middle of winter, so you have to be prepared to deal with everything that goes along with that.”

While simply surviving the race is essential, getting to the finish line in good time is the goal. With these two priorities in mind, it’s all about finding a balance between functional lightweight travel and packing the right equipment to ensure survival.

Those competing in the ITI are expected to be entirely self sufficient, which means carrying food, water, and sufficient gear for warmth. There are two checkpoints where riders are able to replenish supplies, including food and batteries, which must weigh no more than ten pounds. “The checkpoints are roughly 30 to 80 miles apart and you get warm and eat something in most of them,” said Oatley, “but in some conditions mileage is irrelevant … The stretch from Puntilla Lake to Rohn is about 35 miles but this year it took me 57 hours to cover due to some extremely bad snow conditions.”

“Self sufficiency is paramount,” says Oatley, an avid cyclist who has competed in many of the popular epic races, including the Leadville 100, 24 Hours of Moab, the Colorado Trail Race, solo Race Across America in 2007, and the ITI the last five years in a row.

The BikeOatley chose to use a Speedway Cycles Fatback because the titanium frame weighs less than a Surly Pugsley and features a no-offset design. Using a 165mm Hadley rear hub, the Fatback design allows the rear wheel to be dished to the center, just like a front wheel, yet with no interference between the chain and tire.

Oatley uses Nokon housing because the solid aluminum shells stand up to the cold better than other synthetic cable housing. In extremely cold temperatures, traditional housing loses its malleability, putting it at greater risk of cracking.

Equipment choices like these make sense, but why aero bars for a race that averages about four miles per hour? “Using handlebars to push the bike has resulted in some nerve problems in my right forearm,” said Oatley, “I found that the aerobars provide a very neutral arm position for bike pushing—plus they provide a bomber mounting point for my bivvy system.”

So how much pushing should one expect to do in the ITI? “In a ‘normal’ year you can plan on pushing a bike about 50 to 60 miles,” said Oatley. “This year I probably pushed between 110 and 130 miles.”

In temperatures as low as -40F, common grease and chain lube can begin to work against the rider. “The first absolute imperative is to remove the factory grease from the free wheel mechanism,” said Oatley, “The factory grease will freeze around zero degrees.” Oatley chooses to use arctic-grade Mag 1 grease. “All other lubes can get pretty tight so my race bike has a bottom bracket that I soaked in kerosene to remove as much of the lube as possible.” Oatley also removes the grease from his hubs and replaces it with Mag 1.

For chain lube, Oatley prefers a normal Finish Line Dry Lube. “I carried a small bottle during the race and reapplied it three or four times,” said Oatley.

“Tire pressure is the name of the game in snow riding,” said Oatley. As you can imagine, the pressure required to comfortably ride a 3.7-inch Surly Endomorph is quite low. “During the race this year I started with around 15psi,” said Oatley. “Pretty quickly I dropped that to something less than 10psi… By the end of the race I was probably running 5psi or less.”

A few modifications can go a long way during a 5-day race through Arctic conditions. In an effort to save on weight, Oatley drilled 108 one-inch holes into each of his 36-spoke, 80mm wide Remolino rims, which reduced the overall rim weight by about a third. He also modified his Selle Italia Flight saddle by covering it with a 5mm thick seat cover. The pad provided a good cushion for the nearly six-day race, and also helped as a barrier to the cold.

And in a last minute decision, Oatley decided to replace his six-degree stem with a 17-degree riser stem. With previous back injuries, Oatley said that “a relaxed position is better considering the course record is 4.2 miles-per-hour.”

Simply using the Lake MXZ300 mountain bike shoe is not enough to keep a rider’s feet warm in arctic conditions. Oatley protects his feet by buying shoes about four sizes too large and then wears between three and five socks, including booties. Oatley’s typical sock configuration includes an RBH Designs Vapor Barrier sock, a medium and a heavyweight wool sock, and a waterproof nylon bag.

Even though it seems like a lot for a bike, Oatley said that his bike only weighed about 28.5 pounds and cost just about $3,500 (about $6,500 if you add the gear), not including the labor spent drilling 216 holes into the rims.

Winter Foot System

footsystem_1024


A - Liner sock, Generic Polyester Mens Dress Sock
B - VBL Sock, RBH, Single Layer (top)/Insulated (bottom(insideout))
C - Insulation Sock, RBH VBL Combo (top)/Hollowfill Wool(bottom)
D - Boot, Solomon B52 TS GTX (top)/Insulated Footbeds(bottom)
E - Gaiters, Outdoor Research, Epic Fabric
F - Overboot Insulated, Wiggys
G - Overflow Overboot, Wiggys

Tony,

I think I have about the same $ invested in my footsystem...I guess you get what you pay for in footgear. You could probably (lol, I know you can) go 2 the second-hand store and pickup a pair of old softsole sorels and then head-over to the food store and clip a dozen fruit/vegetable plastic bags for vbls, slap a good gaiter on them...and get pretty good results too...for way way less!

Really liking the idea of layering on the feet, just like we do with our other clothing systems, because it adds to the variability... the real trick is accommodating all conditions...on expeditions and esp. here in the Delta I'm forced to work across the gamut of conditions...thus, the layered, interchangeable, foot system.

I gotta say...

the Wiggys overflow waders, at 8oz, tiny packsize and fitting over all my gear...I don't leave home without them...life saver here! If we were to have a race here on the Kusko I would make them mandatory gear.

the Wiggys Lamilite insulated boots are way way warm....preliminary look is good but the verdict is still out on how far you can walk in them though...will know more after spring expeditioning.

RBH vbls are way superior to anything else I've used...insulated version is rightup there with any other sock combination I've used.

the Solomons are IT for me...super light for a winter boot, plenty warm just the right amt. thinsulate (I think 400gm), just the right flex in the sole which doesn't freeze and most important, the fit for for my wide foot is perfect...I'm using them @ 2 sizes-oversized. A real winter hiking boot...the only mods I made were that I nailed some sheet metal screws to the sole for traction and put some longer laces on them.

using men's dress socks is not only 'style'ish' they are the only liner socks I've ever worn that actually 'stays up' and doesn't sink into a ball under my foot...thats good!

Lost Coast Expedtion

http://lostcoastbike.blogspot.com/

The Lost Coast is a stretch of wild coastline along the Gulf of Alaska starting from the eastern end of Prince William sound extending some 400+ miles to the south and east. Bordered on one side by thousands of miles of open ocean and breaking waves and the high glacier covered Chugash and St. Elias Mountain ranges on the other. It is not protected by islands and is fully exposed to the brunt of the sea and weather systems that swirl in the gulf building power, then slam into the mountains to the north. With that said, it is a incredibly beautiful and wild stretch of coastline.

Starting on August 18th, we will attempt to make the journey between the towns of Yakutat and Cordova. Biking the beach when we can, foot when we can't and use packrafts to cross the large bays and portage the numerous glacier fed rivers. Our route is front loaded with challenges. Close to Yakutat we will need to cross the Hubbard Gap - a massive calving tidewater glacier bordered by steep & rocky shoreline. Heading North we encounter the Sitkagi Bluffs and the worlds largest piedomont glacier, the Malaspina. Next up is perhaps the biggest challenge of Icy Bay. A 3 mile crossing of a bay chock full of icebergs. Continuing northward is cape Yakataga, the mid-way point and food drop that will be delivered by a bush pilot.

Miles of beach later we reach the barrier islands and the beginning of the massive Copper River Delta which we must finally stumble across to reach to town of Cordova about 300 miles of wilderness from where we started. Fun!
