|Carbon Fork Query: HELP!||kickoi_bikerdude|
Oct 7, 2003 3:08 AM
|I ride mostly MTB, so I'm not too familiar with full carbon forks for road bikes. This is my first time to own a full carbon fork, a Mizuno that came with my new Fondriest M. di Campiglio frame. My problem is that everytime I ride the bike and the fork hits an object on the road, i.e. a manhole cover or a large gap on the pavement for instance, there is a loud "crack" or "tack" or "thwack" sound that I swear comes from the fork. But upon later inspection, I would not see any damage. This happens regularly enough that I'm beginning to ignore the sound already. Should I be worried that the carbon steerer would break? For what its worth, I do not hear the same sound coming from the carbon stays, which remain silent on all road imperfections. BTW, other than the strange sound coming from the fork, the bike rides and handles great. Any comments or suggestions with regard to carbon forks or their traits and characteristics in general would be appreciated. Thanks!|

|I own the same bike and heard the sound that you describe, once, when I came down my drive which has a curb at the end, but you should not hear this type of noise when you hit smaller cracks and bumps.
Better try readjusting the headset. Riding very long with a loose headset will destroy the bearings pretty quick. Loosen the stem clamp bolts and tighten the top cap some more. Any amount of play in the bearings is bad. Unless you feel binding or noticeable resistance when the fork is turned, the bearings are not too tight.

|Try putting a finger on something else. Put a little pressure on the shifter/brake levers with your fingers to see if that doesn't stop the pop. That will not fix anything but there is a good chance the noise could be coming from something other than the headset.
