My buddy is looking at getting the Zwift Hub One. He’s concerned by this line in the Cog description:
Zwift Cog works with almost any 8-12-speed bikes
He’s got a Diamondback Lakeside hybrid bike from 1997. The cassette is a 7 speed with 11-28 teeth. The chain is listed as 1/2 X 3/32.
My thought is that he might need a spacer to get the Cog into position, but I defer to the experts here. Can this 7 speed work with the Hub One? Many thanks!
