A fibroblast is a type of cell that synthesizes the extracellular matrix and collagen,[1] the structural framework (stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals.
For example, a 700 x 20 C road tire would be a 20-622; a 700 x 38 hybrid tire would be a 38-622. The width difference between these sizes would make them less-than ideal replacements for one another, but any rim that could fit one of them would work after a fashion with the other.
Find the tire size of your bike by looking on the existing tire or the wheel rim. The first number will be the diameter and the second number is the width of the tire. Example tire size: 26â x 2â. If you donât have the old tire or canât find the tire size on the rim, you can measure the rim yourself.
