Yeah, i've been doing that hamster, but i'd like a nice shiny pimpy topcap to finish off my build....i should've bought one back in the mid 90's when i first purchased the stem but i only used the stem for a few months then retired it to my box o' bike bits and promptly forgot about how crap the plastic cap is till last month when i fitted the stem to my ss build.
Apparently the alloy topcaps are now pretty rare.....bugger!
