A couple of weeks ago I noticed some new creaking sounds from the boom area of my Silvio, which had been silent since the last time I greased and tightened everything. The sounds appeared to be coming from the slider clamp (which clamps the boom above the fork). After some disassembly I discovered that the clamp is damaged. The clamp bolt is keyed at one end to fit into a notch in the clamp, and the notch has expanded. The surrounding area is also a bit scraped up. I can't be sure this is causing my creaking problem, but if you want to avoid similar damage here is my advice: Obviously don't try to over tighten or gorilla-arm the bolt. Do not try to pick up the bike by the boom, or clamp the boom to a repair stand, while the front wheel is off. Without the front wheel skewer to hold the front triangle together, the boom will act as a big lever putting torque on the clamp/bolt assembly. I think this is what messed me up in the first place. Here are the photos where you can see part of the clamp notch has been turned into a wedge. I imagine the bolt is made of harder metal than the clamp.
