i have 2 friends that bought a rup off amazon for $50 shipped. all you would need to buy is griptape and grips. if you wanted to you could switch to ics(using ics on threaded forks is much better than using locknut compression) and buy some metal cores.
i am going to this tomorrow for sure. I will be competing in the intermediate class, but i dont think im going to do so well since i dont ride much park.
i will be the guy with a green mgp and mckeen bars, so hmu
