Ok,
I don't ride fixed, but I like looking at pictures. Some, and only some of the conversions reach a high level of aesthetic achievement. Far too many are purely terrible. I'm personally against drewing, but not against conversions. As long as they avoid the all too common "Ronald McDonald" color palette. I wish that the average fixed gear builder would reach higher.
I've got a couple of future road three speeds in the basement that wont be getting their Deraileurs back for a long time, but they never had cast hangers or any other braze on's to speak of.
