Problem Solvers Headtube Reducer Cups

Here's the dilemma.  You have a sick Amp F3 fork and an old Surly 1x1 collecting dust.  They belong together, like tarragon mustard and really cheap hot dogs.  But the Amp fork uses a 1" steerer tube and the Surly's headtube is 1 1/8th.  No worries. Install these headset reducer shims and a 1" headset and you're ready to party.  I've run these off road, they're safe, secure.  

Reduces the headtube inner diameter from 34mm to 30.2mm, so you can run a 1" threaded or threadless headset on a bike made for a 1 1/8" aka EC34 headset.  

Pack of 2, IE two cups for one bike.
