There are very few types of bikes that do not meet the size requirements, so be sure to measure the space at the point of the dropouts between the forks if you are concerned. To ensure proper fitting, do two things: 1) Check your wheel size listed on the tire to make sure it is either 16″, 20″, 24″, 26″, 27.5″, 700c, or 29er & 2) Measure your forks as they will need to be between 3.8 – 4.05 inches or around 99mm between the front forks. This is the point where the wheel axles connect to the bike. Please review the image below to ensure correct sizing prior to purchase.
