Excellent, a clear simpler and cheaper alternative. Question is- if you're doing this alone, how do you hold the fork leg down for support? Critical to hold it securely, so that you can apply pressure with this tool. Square tubing full length support type tool for $80 more. The chinese version even uses RaceTech's same part number!
I've disassembled forks before, most easy, some difficult. The tool choice depends on how much tension the springs are. If not much, that simple ring tool will work. If Tracer 900GT fork springs happen to be the opposite, then the full length compressor tool is the way to go. I don't know yet. Did you do this yourself with that ring tool?
