Instead of going from a 20” to 26” rear wheel on my Tour
II, I decided to go with a 24” instead.
The new wheel gives me--in effect--one more speed on the top end and
puts the gears in a better range for my style of riding. The biggest obstacle is the lack of choices
for wheels and tires. Fortunately I
found a wheel that matched the front ones, and tires are available in 1 ½”
width (Kenda) and 1 3/4“ (Schwalbe). I couldn’t find a 24” wheel with a free hub,
and had to go with a free wheel instead.
I really don’t mind that so much, and it makes no difference in my
riding experience. The dropout extensions
are the same as for a 26” wheel. Two other
changes included the addition of a custom rear fender and upgrade to a Shimano 9-speed
derailleur paired with the stock 8-speed Micoshift shifter. Here’s a link to a picture of the trike:
