Here's the latest from Camping World. 17" tires and 451's were a hit, so why not 22" tires?
Using the formula from Sheldon Brown's lost web page, I have calculated this bike's co-efficient of comfort at a very excellent 20.95 where, according to Mr, Brown, 25 = Superb Comfort and 0 = Supreme Agony.
For reference, a 20" wheeled bike, with a 6" wide seat would be rated at 11.43, while a bike with 26" wheels and a 10" wide seat would rated at a near perfect 24.76.
The hell with elastomers!
