Is This Right?
I am installing a 7-Speed cassette on a new 8/9-Speed rear wheel that I just bought from Nashbar. I was also sold a 4.5mm spacer by Nashbar, and told I'll need to put it on the hub b/4 sliding in the cassette.
Well, I just got my wheel back from the tech that worked on de-stressing and tensioning the wheel, and he put two spacers, with a combined thickness of 3.5mm on the wheel, instead of the 4.5mm single spacer I had given him. He claims the 3.5mm spacers are gonna work better, and that the 4.5mm was way too thick.
I have not had time to ride the bike, so as to make sure the chainline and shifting both work well.
Is he right? Or, should I remove the two spacers (3.5mm total) he installed and replaced them with the single 4.5mm spacer Nashbar sold me?
Thanks for all responses.
