I have not kept up with the Iditarod since they banned poodles:

I think this guy on the bicycle is amazing. Usually the cyclists show up when we're out in Nome, after about 15 or 20 mushers. I can't imagine riding 100 mikes a day on the terrain that these guys cover.

The bike's big advantage is going down hill. On the other hand the low gearing of such wide tires bikes makes for slow speeds (Through probably faster then walking).

One advantage he did have over the dogs is the dogs time on the trail is regulated.

What they are not is affordable.

Titanium is, given same Mass AND Volume, stronger then Steel or Aluminum. Aluminum is stronger then Steel given the same MASS, but weaker if using the same Volume. Thus Aluminum frame bikes have to have thicker tubes then a Steel Bike, but Titanium can use tubes the same size as Steel and still be stronger.

Titanium dropped in price in the 1990s, I remember just the frame being offered for about $900 (made in China Frames). You could get an Cannondale Aluminum frame for less then $200 at that time (Cannondale had a program in the 1990s, if you traded in an old frame, they let you have a new Cannondale frame).

Trek went into Carbon-Fiber right after 2000. Carbon-Fiber offered the stiffness of Titanium at a reduced price, through higher priced then Aluminum.

Stiffer frame, easier pedaling. Given that pedaling is the main restriction on most biking, it is the biggest restriction and anything that reduced pedaling is good. Thus you will NOT hear me talk bad about his bike.

On the other hand, it is a bike designed NOT to go on paved roads. That is the only comment you will here from me AND given its gearing (the front gears was roughly the same as the small gear on a regular three speed front gears) you are NOT talking of very fast speeds. Thus my comment that it may have been almost as fast to walk, except for going downhill. On flats, the bike probably would beat out someone running, but going up any grade, you may be better off walking the bike, it might be faster.

My comment is on the type of bike and its limitations, it will go good over soft terrain, unpacked snow, mud, sand etc. But it would be slower then most other tires and bikes on other terrain do to its much wider tires given more roll resistance. The old fashion 1 1/2 to 2 1/2 inch, or if you are metric 35-65mm, tires are much better all around tires, can be used on paved roads (through inferior to 1 to 1 1/2 inch tires or metric sizes 25 to 35 mm, for road racing use).

his 2009 rig lists a standard triple crank with MTB gearing. a lot of builders are eliminating the big ring outright these days, with the exception of true XC bikes. I recently purchased a 2013 Giant Trance X1 29er, and it was setup as 2x10, which is fine, because I can't even remember the last time I used the big ring on any of my bikes. pulled it off my other trail bike a few years ago and replaced it with a bashguard.

And I believe it is still the case with race bikes and other "road" bikes. On my triple, used mostly in roads, I made the observations that I tend to use the low front gear in areas where I am mostly going uphill, the large front gear in areas where I am going mostly down hill and the middle gears on flat areas. If I am pulling a trailer, I tend to drop down a gear or two in the rear, but not in the front.

My point is when commuting going downhill, the Large Front gear is usable. On Rails to Trails, I rarely use the large gear, the grade up or down is to low to justify anything but the middle gears, but when I operate in roads with large sections of the road going mostly uphill or downhill, I tend to opt for the small front gear when going uphill, and the large front gear when going downhill. In one stretch of road I travel on, I end up using the large gear going down the grade, then to the front low gear after I make the turn at the bottom of the grade, for the grade then turns sharply uphill (After I had shifted to the smallest front gear and the largest read gear I end up walking the bike, it is a 12% grade at that point and I value my knees).

Yes, I shift from large front to small front skipping over the middle gear for the shift in grade is that quick.

That is one of the problems with living in the Appalachian Mountains, the mountains are all climbable in fact you can walk to almost all of the mountains standing upright. Thus they are also bikeable, but you have quick changes in grade on the roads in that area. In the West, they had enough brains NOT to build roads in such areas, but here in Pennsylvanian they had a habit of paving over any goat path they ran across. Thus we tend to like three front gears for we can use all three. Yes, I admit I rarely use the large ring on trails, but it comes in handy on roads, where I tend also to bike on with the same bike.
