Maintenance, Mechanics, & Tools / Carbonda fork vibration
« on: March 06, 2024, 12:23:25 AM »
I've been having some vibrations on the fork of my Carbonda 707 gravel bike. Some times when I am riding on a bumpy surface and braking lightly, the fork will start to vibrate, like a shudder almost. I can't get it to happen on smooth surfaces, and it seems worse if I have less weight on the front wheel. The headset appears tight. I squeezed the front brake and rocked the bike back and forth and couldn't feel anything loose. The hub seems fine. I didn't check the brake rotor to make sure it's tight, but it doesn't feel or sound like that was an issue. The brakes are GRX with Shimano resin pads and Shimano rotors.
Does this indicate a problem with the fork? Or am I just somehow exciting its natural frequency in some conditions?
