I was searching for a release date on the 10speed twisters. Came across a thread where a German Co. called Fantic26 machined new indents on 9speed XO twisters to work with a ten speed Shimano Der. I bought the complete set reworked, but I think they will retrofit if shipped them your parts. Anyway,works excellent and the company ships immediately. Took 10 working days to receive the parts.
