Snow bikes were invented to provide more floatation than a standard mountain bike. It stands to reason that the wider the rim, the more floatation you will achieve as long as you have a tire that will take advantage of the rim width. My first snow bike, the Wildfire, had 65mm Large Marge rims. My Fatback came with 80mm rims. In my quest for more float, I just had Fitzy's lace up a set of 100mm FlatTop rims.
The old 80mm rims next to the new 100mm rims
The project is not quite as simple as relacing the hubs to new rims which is why I call this an experiment. The 100mm rims take up a lot of real estate in the rear of the bike and I am going to lose a couple of gears in the process. I am hoping to keep 7 gears but I may end up with 6 in the rear to go with my triple in the front. The FlatTop rims themselves are very average in quality so I am not sure about longevity. I will post more on the experiment once I dial things in a bit more.
Fat wheels bolted to a Fat fork. Phat!
Today was my first ride on the 100s and they are very stable. The additional width and change to the tire profile is noticeable. We were relegated to backroads but we did ride through 6-8" of fresh snow on the unplowed section of Stateline Rd and I broke trail easily. Sweet!
I really wish my Endomorphs would last more than one season. Running them at 4 PSI wears out the sidewalls long before the tread.
We had a great ride on Teton Valley backroads and were stocked that the precip remained frozen and didn't turn to snain...or worse. :)
This guy didn't wave back or smile when we said hello so we will call him 'Crusty' from now on. He did have a cool snowblower tractor though.
M wasn't having any fun at all.
Riding & Smiling
Even more smiling...
Yeah, we still have a LOT of snow here Teton Valley.
