The same thought popped into my head, the recommendation isn't about style it's about safety. May not be the best to have an oily chain running millimeters from your lone breaking surface. And I've heard mixed reviews about their breaking power irregardless of the chain. Have never heard they stop great, either just okay or sucks. Anybody have any personal experience with a sprotor that can give him good advice before he builds a death trap?JTR in Queensland supply Akront/Morad rims.
I don't think I'd use a sprotor. Especially as the only brake.
