The Hamilton Triumph dealer never stocks stuff. More than likely will have to get it shipped, regardless of where you buy, even from a store front. The good side is riding season is pretty much over so lots of time to wait for the mail.
My street triple has the Pazzo short levers (came on the bike used). The build quality is a bit better than Chinese/eBay stuff I've bought for other bikes but not 10-15 times the price better. They look exactly the same as the eBay stuff too. Just avoid the coloured ones since the finish will more than likely wear off and will end up being silver anyway.
