The tool will work on the 10 speed chain though it takes more force to compress the link.
10 speed Powerlinks may require the use of channel lock plyers to force the tool in.
You can get one for $5.
Send me an e-mail requesting a Squeeze Link and I will send you one.
Payment can be made through my PayPal Account, under kelley@bikemountain.info
Or you can send me the $5 in the mail.
