thin blue line
Received my new wheel set in the mail today. They are Sun Rhinolyte w/ XT hubs 8/9. My bike is a 7 speed so I ordered a 7 speed Shimano cassette and a 4.5 mm spacer so that the cassette could be used with the 8/9 speed wheel. I installed the spacer, the cassette, and the two loose cogs and upon doing so, I noticed that on the backside (towards hub) of the cassette, there are two protrusions. These two protrusions sit upon the spacer, which in turn results in the cassette not seating properly. In addition, the cassette lock ring does not seat far enough on the cassette to thread. Should I dare file the spacer to accommodate for the protrusions or are there different spacers out there? Please help, I cannot stand to ride on those single wall rims a day more. Thanks.
