id suggest maybe moving the wheel a little more forward in the dropouts. not only does it look better but you will actually feel the short back end. you might be able to just take out a link out of your chain. if that makes it too short just add a half link
my 2010 lacondeguy inc feels super nice with a slammed back wheel
i took this photo yesterday, but i had the same thoughts as you and did just that, now the wheel is slammed and it has a brake, looking forward to trying it out tomorrow. thanks for the input (:
