its a ****ing bike, billions of bikes exist. it isnt a super rare bike that will make the gods cry if he converts plus he can put everything back later...

i say go for it bro, try it out ride it as single and if you enjoy it save up for a proper single speed/fixed gear frame with the correct dropouts and then put said bike to its original status.

so tired of hearing OMG DONT CONVERT THAT ITS HERESY... its not like hes taking a ****ing hack saw to the frame.
