Just wanted some opinions on this singlespeed conversion kit with a godspeed tensioner, shimano dx cog and spacers http://cgi.ebay.com/ws/eBayISAPI.dll...e=STRK:MEWA:IT
ends up being less than 55 for everything. The cog and spacers are standard issue from what I have seen so I wanted to know if anyone had any opinions on the tensioner.

EDIT: I just noticed it in the mountain bike section. Would this work with a 8speed rear freehub for a road bike? I am not sure what hub is on the bike (need to ask the seller) but it uses shimano sora components and is a cassette in the back.
