Is the bigger front wheel to better roll over obstacles, or is it
just a demented fashion statement? Conversely, does the smaller
rear wheel provide any real advantage?
Back in the day, Charlie Cunningham built MTBs with a smaller rear
wheel- IIRC 20" rear and 26" front. Many dirt motorbikes have a
smaller rear wheel. I have no idea why. Maybe Carl Fogel does, he
used to ride trials and the like.
Dear Tim,
Sorry, but we fooled you.
Don't feel bad, since 9 out of 10 trials riders will mistakenly
insist that their front tires are bigger.
After all, trials machines use 21-inch front rims and 18-inch rear
rims, so the front tire must be 3 inches taller, right?
Nope.
Interesting! Never having and anything to do with motorcycles, I'd not
thought much about this. The cycling parallel would be something like
having a 650B X 37 rear and a 700C x 18 front. The overall diameter is
just about the same, but the section width of the tire is very different.
