Front wheel axle size

Measure it? It'll be either 3/8ths, 10mm, or 14mm. 3/8ths and 10mm are pretty much identical, just a slightly different pitch thread. 14mm is quite noticeably bigger.

What bike is it? Chances are it's 3/8" unless it's an older bike.


3/8" axles are roughly the same diameter of a standard pencil so maybe you could compare it that way, 14mm would be bigger than a pencil

3/8 is definitely still noticably bigger than a pencil so be careful with that check. Just measure. It will either be 3/8 inch (most likely) or 14mm, which is a little bigger than 1/2 inch (not likely unless your forks are 10 years old.)

10mm is a lot more common than 3/8ths
