I recently just purchased my first 9 zero 7 last week. This is my first fat tire and I had a question about the disc brakes. Notice when breaking hard, the torque causes the fork to flex in under the bike. There seems to be a large amount of stress on the frame and fork. There is no play in the headset or anywhere at rest but feel a shift or play in the front when braking and popping over stumps. Basically, is this normal? Is there any concerns? Is there anything I should look out for? I am used to my suspension eating up the brakes and haven't rode a rigid frame in years. The brakes are avid BB5s with 6 inch rotors. Nate's and toobs, rolling Darryl, 907 headset, 907 hubs. Thanks!
