just finished building my guerciotti, and took it for a spin around the block. for it I bought this IRD freewheel: http://harriscyclery.net/itemdetails.cfm?ID=2357
but while riding, I noticed a slight friction pedaling, at first I thought the wheel was rubbing against the frame slightly, it was quite noticeable. But that wasn't it, and the new bottom bracket was super smooth also. What does that sound like to you guys? The freewheel is right out of the box, does it need to be oiled?
