Hello all. I recently got the itch to start riding again after many years, and decided to get a decent bike instead of a cheap Wally Mart piece of junk. I test rode many, and ended up with the Gary Fisher Piranha (http://www.fisherbikes.com/bikes/bike_detail.asp?series=genesis&bike=Piranha). The dealer told me it was an entry level bike, yet a high quality one, and its sorta a do it all bike. So far that seems accurate to me. Over the last week I have riden it quite extensively on some moderately challening single track. Big hill climbs, big downhills, creek crossings, granite climbs, and the like. After looking around on the internet over the last few days, I have learned about all of the different bike classifications. So is the Piranha considered an XC bike? It is in my nature to push things to the limit, but my $650 bike is NOT something I wanna trash. So what are the limits of this bike? I have started doing some small drops (2-3 feet to a downhill transition) and have gotten pretty good and landing those. Some of the downhills at the place I ride are covered in roots, and if I go too fast it seems to rattle the teeth out of my head. Will doing these kinds of things hurt my bike, or can it handle it? I know its not a freeride or downhill bike, so I'm not expecting to do any of the crazy drops I see people doing in videos, but will it stand up to a fair amount of abuse. Or should I just stick to the singletrack? Thanks alot everyone!
