The main difference between 700c and 27-inch wheels lies in their size. 700c wheels, common on modern road, gravel, and racing bikes, have a diameter of about 622mm. 27-inch wheels, traditionally found on older bikes, measure approximately 630mm in diameter. Although seemingly similar, the 8mm difference affects compatibility with tires and frames. Broadly, 700c wheels cater to performance and versatility for various terrains, while 27-inch wheels are suited to vintage or classic bikes, potentially limiting tire choices and performance gains.
