Size Of Standard Road Bike Wheel

Hi i am beginner planning to buy cycle 5 7 ft height 32 leg size which wheel base would suit me 26 or 27 5 though planning for mountain bike most my trails will be on mud and rough roads and bumpy ride.

Size of standard road bike wheel. Racing bikes use the 700c size which has a tire bead set diameter of 622 millimeters. For standard hardtails our mountain bike size chart should be a god send. A standard road tire is 700c x 23mm indicating a tire diameter of approximately 700mm and a width of 23mm. Mountain bike sizing can be affected by suspension and your tire choices.

This wheel size is the largest available for conventional bicycles giving a racing bike more stability at high speeds. The history of that name would need a whole other blog post to fully explain but the short version is that it came from international tire sizes where the outside diameter would be approximately 700mm and multiple rim sizes would be labeled 700a 700b 700c etc. In some site it suggested frame size of 18 5 47 cm size. So make sure you look at a tire size chart and try a full suspension mountain bike for size before buying.

His calculator uses an pre defined diameter for every rim tire combination and his diameters are almost always different than what the math would predict. When shopping for road tires you ll look for 700c x your preferred width 23mm being the slimmest option and going up to 36mm. The venerable sheldon brown has a gear calculator that uses a different method to determine wheel size.
