Does anyone have the time to let me know about wheels ie sizing meaning 700c :?pros and cons of various hole 32 compared 36 if to much to type book recommendations greatly appreciated 
700c is the standard for road wheels. 26" for MTBs. Possible to get frame forks that will fit other sizes.
The traditional sizing systems are based on a measurement of the outside diameter of a tire. This would usually be measured in inches (26", 27", etc.) or millimeters (650, 700, etc.).
Unfortunately, evolution of tires and rims has made these measurements lose contact with reality. Here’s how it works: Let’s start with the 26 x 2.125 size that became popular on heavyweight “balloon tire” bikes in the late '30’s and still remains common on “beach cruiser” bikes. This size tire is very close to 26 inches in actual diameter. Some riders, however were dissatisfied with these tires, and wanted something a bit lighter and faster. The industry responded by making “middleweight” tires, marked 26 x 1.75 to fit the same rims. Although they are still called “26 inch”, these tires are actually 25 5/8", not 26". This same rim size was adopted by the early pioneers of west-coast “klunkers”, and became the standard for mountain bikes. Due to the appetite of the market, you can get tires as narrow as 25 mm to fit these rims, so you wind up with a “26 inch” tire that is more like 24 7/8" in actual diameter!
A second number or letter code would indicate the width of the tire. (26 x 1.75, 27 x 1 1/4…650B, 700C…)
the more spokes you have, the stronger and heavier it is. I ride with 32 spokes on all my bike (rear wheel of fixie is 36 spoke but only because both the hub and rim where on special). I do a lot of endurance road riding and various people in my club have tried lower spoke count wheels and the majority of them have gone back to more traditionally laced wheels.
