Sette ST-1858M Headset Cup Remover
Easy, Clean Headset Removal
The Sette ST-1858M Headset Remover is the easiest and cleanest way to remove a majority of headset cups and it will fit standard and oversize headsets. Pull The ST-1858M through the headtube until the flared ends snap in behind the cup and then tap the reinforced tool head with a hammer and the cup comes out cleanly. The ST-1858M is constructed of durable, heat treated alloy steel with a nickel finish.
Note: Will not work for 1" headsets
Looks like a nice tool, but someone forgot to mention the width is 28.6mm which is probably great for thread 1 1/8 headset. But won't work for a 1 inch headset.
