i love it! this is something i was looking for in a freewheel to help with easier climbs uphill. the install was easy and i love the spoke guard thats attached to the freewheel!

Wanted better hill climbing from my XC100 E-bike which had the MF-TZ500-7 14T-28T sprockets. Changed to this cassette but with 14T-34T. It has the same tooth count on all the sprockets except the largest with 34T. Now I can go over even steeper grades.
I figured it should be an easy switch since the present RD-TY300 derailleur is compatible. Well it was easy except for two issues. Had to drill out the center hole in my old FR-1 Freewheel remover tool to 1/2 in for the bigger diameter rear axle. (The newer tool has a bigger hole.) Also had to remove the plastic chain guard on the new cassette. The old cassette did not have the guard. and attempting to tighten new cassette with its guard jammed the free spinning function. To remove used screw driver/hammer and laterally hit and rotated the plastic guard off the steel mounting posts.
(To avoid spoke damage check L limit screw is properly set so chain does not fall between spokes and cassette.);
