$2,400 doesn't really buy much these days. A couple meals at L'Atelier or Le Bernadin, a .5 carat Asscher Diamond, 24 random rub and tugs in the Valley, no not that Valley. Regardless, buying a decent descent bike for such is rare. Enter the Kona CoilAir, seems to be a low cost fav. Not that I really care about freeriding, seems kinda dumb to me, but here you go, don't say we don't write about bikes. Here's someone who likes that bike via MTBR:
Over all, I love this thing. It can do everything pretty well, and rules at bike parks on 4x, slopestyle type stuff, north shore stunts, and extremely tech downhill single track. Kona also manages to spec great bikes for the price, so great value.
And some drawbacks:
The rear suspension is extremely linear. The choice is pretty much between plush absorption or pump it up stiffer than preffered to make big drops to flatter landings a bit better. Luckily the dhx 3.0 bottoms smoothly and the boost valve helps it to ramp up on high speed hits. ** the stock maxxis advantage tire on my bike rubs on the frame when it bottoms out. Stinks that kona didn't think to fix this, but a tire with a shorter casing will do the trick** Seat tube angle is a little slack for serious xc stuff, but moving the seat forward helps a bit.
