i hear pugs are hard to convert because of the french threading or something like that. like if you like the cranks on it it's okay but getting new cranks is hard or something. but if you're just gonna take off one of the chainrings and throw on a new wheelset then boones, blueline bike lab, and houston bicycle co would all be okay i think. those are all the ones i've visited, there's also west end and some other shops.
