No ALL of it is slack , bloody hipstersThe chain is slack as well.
I'm sorry, that comment made no sense to me, at all.Placeholder for explanation by Father Ted.
I thought it was a deeper section rim, but it could be a bigger tyre as well.Both wheels are the same size, but the rear wheel is using a bigger tyre, making it look bigger than the front
searching around looking at bull horn bars on t'e tinterweb and i stumbled across this, some hipster thing with the rear wheel bigger than the front by the looks of things and the top tube is at the most ludicrous angle yet!
