A GuestSo this isn't something you necessarily "want" to buy, but something you'll have to buy if you replace your bike's headset with something that doesn't fit the old brake hanger...or if you get a new fork with canti bosses on a frame not designed for them.
If you're running a 1" threaded stem (like 90% of pre-1990's bikes), to use this part you will also need to purchase the 22.2 to 25.4mm shim. Otherwise, this won't clamp.
