    115mm. If you include the full stock headset it's 128mm

    Guessing he's looking for inner diameter not length.

    He'll need both if trying to get a JUnit fork in there being that it's a tapered steerer. I'd guess its 95% 44mm. I would personally just sell the Riprock rather than upgrading. Lot of stuff wrong with that bike, not just the fork.

    I agree the riprock is not a great bike. When we bought it back in 2017 it was hard to find a 20" bike with disc brakes and gears for $400. I was looking at the 20" J Unit the other day and it was listed at $240 including tax and shipping on Chain reaction. If it was an easy install I would have bought it, but having to get the tapered headset kit and also figure out how to use the 15mm axle just seemed a little too much.
