All good advice. 180 is not bad, but the more you abuse your bike, the shorter its life will be. If you plan on keeping it for a long time, don't go too crazy. The Rainier is a good bike for XC. You can practice landing smoothly on small drops then work your way up a little. If you do see a jump/ drop on the trail that looks a tad big, sure maybe you could try it, but like Warp2003 mentioned, repeated impacts will weaken the frame. Maybe you will want to get into the whole free-ride thing one day, then you will need a new bike. But for now, 2-maybe 3 feet of air is probably a good place to stop.Warp2003 said:Should be ok for moderate 2' drops.
Just learn to land softly and your frame will last longer.
One hit will not kill the frame but repeated impacts will.
