So far the HG41-7 cassette works great. Very smooth shifting so far. I cannot feel the shift, I got off of my bicycle 3 times to see if the gears shifted....'It did. I also like the 11-28 better than the 13-30 gearing. Less shifting now and less spinning when I'm in the granny gear. Only problem is front shifting. The chain, cassette and chain ring were/are 15-17 years old. My research tells me that a new chain will not shift well on a worn chainring. I had no problems with shifting until I replaced the chain and the rear cassette. I replaced the chain because it was worn beyond my chain gauge. LBS also checked the chain and also recomended changing the cassette. The LBS had a better chain checker than I have. I think I will be getting the chain gauge the LBS had.
