Confirmed!
I put the new cassette on this weekend. I didn't change the chain length or adjust the derailleur cable tension -- just put the new cassette on the wheel and tried it out. The chain length is pushing the limit, but seems to be acceptable (the chain was cut to accept a 12-27). The shifting is outstanding. If anything, it shifts better than it did with the old 105/Ultegra cassette. That may be because of accumulated grime in the hyperglide bits of the old cassette, or it may be that the old cassette was just worn.
I just posted a
full review on the Commuting forum.
