Got one of these on order for my Trek Superfly 100.
The Trek dealership quoted me a price of $1500, installed.
Fortunately I'm friends with the owner of another shop who has agreed to do it for just under $1000.
Dizave opined: Why do you care where the premises come from? They are above reproach. For all intents and purposes, you can just make up all your premises, since they can't be proven anyway. That's why we need premises.
