Just got off the phone with Giant. He said the bike is capable of some abuse. He then went into detail stating that he even jumped a small set of stairs maybe 4-5 steps near the shop. He landed fine with no problem. What he said to me was of course you need to be experienced on how to land properly with good forks to absorb the landing. He did mention that he does not recommend it, but that's what he does and his bike hasn't snapped where the headtube is. Throughout the conversation I had with him, he mentions if my frame was carbon or aluminum. The moment I said I own the composite 3 model of the XTC 29er, his voice lit up and said "well then you're fine, carbon is way stronger than aluminum. If the frame where to reach it's limit and snap from a drop you'd notice instantly. Aluminum would take some time until when it breaks and impales you. We test our frames to make sure it takes a lot for the frame to break. As for carbon, again it's real strong more so stronger than aluminum. I weigh 210lbs, how much do you weigh? (I responded with 180lbs but summer I'll be 165lbs. He then goes oh you're fine!"
Anyhow, he did say going through rock gardens and lifting off sidewalks or small bumps where both wheels are few inches off the ground is fine. He even did mention he landed hard on his front wheel first going off a sidewalk and the frame didn't break. At the end of the conversation I said I was glad I don't have to 'baby the bike'. He goes nah from a rider myself, don't worry the bike can take some abuse, just remember it's a cross country trail bike. I responded with, don't worry all I do is ride at the Don Valley Trails, I'm sure there's no 'mountains' there to jump off haha.
Our conversation is more so a reference, but it's good to see someone who owns a XTC bike doesn't baby it.
