Here's one for the peanut gallery. Over the winter I put new wheels on the Sleek Black Beauty - our 2000-ish Arriva Stowaway. The original EDCO rear hub had failed after about 5000 miles and I ended up with Santana OEM Shimano 48 spoke hubs with Dyad rims and reused the original 8 sp. casette. We have an Arai drum and I had to also buy a new brake shoe mounting plate because the EDCO axle was 12mm diameter and the Shimano is 10.
Everything works well until we stand on the pedals and then we get a scraping noise that sounds suspicously like the plate is rubbing against the drum. I've pulled everything apart but can find no telltale scrap marks around the perimeter of the plate and there appears to be about a mm of clearance all around. Has anyone ever run into this? I could be all wet and am looking in the wrong place for the noise. When pedalling with even moderately high pedal pressure the bike is silent.
