Experimented with using a smaller 20" wheel on a Softrider.
With the stock 26" wheel, head angle is 71 degrees. Using 20 inch 406 wheel, the head angle increased
to 75 degrees. The nimbleness of the bike improved without being too twitchy.
With the 26" wheel, it felt riding a mountain bike with 2 inch wide tires. With the 20", more like a road bike.
Will have to put in more miles to see if the conversion will stay. Very promising though on the short test ride. The crank height is now also about 3" lower than stock. Putting your feet down or stopping seems to be easier now.
