Question:

What is the difference between male and female axles? And threaded and threadless pegs?

Hi, I‘m no bike expert. I recently bought a BMX bike, and would like to get a pair of pegs on the rear. However, I do not know which type of pegs to get. The rear has the axles sticking out, about a little over 1/2 an inch sticking out each side. Which kind of pegs do I get for that kind of axle? And for future references, does the rear of my bike have a male or female axle? Thanks for your time.

Answer:

It has a male axle. Male axles have axles that go completely through the hub and out both sides, and nuts screw on to tighten it. Female axles have a hollow axle that is only inside the hub (Doesn't stick out at all), and there are bolts that screw into the center of the axle. Threaded pegs are the cheap, screw on pegs that are found on department store bikes. They are complete crap. Threadless pegs are the pegs that have no threads. You have to take the nut/bolt off, put the peg on, then tighten the nut/bolt as normal. All good pegs are threadless. That's what you will want. You'll want to measure your axles. They will either be 10mm (3/8) or 14mm. That is your peg size. I will say that running only 2 pegs on the back is pointless. You can't do anything with it. You should either get 2 pegs on one side, or 4 pegs.
