hope op didn't f**k himself rushing to remove all the stickers. oh_snAP1, if you had doubts about the fit of your bike, why did you mess with it?

biria is more known for their dutch & city style bikes but here's some info on their ss/fg bikes & it isn't pretty:

the only mention of their ss bike for $299:

it is a hi-ten pos & best thing would be if you could return it for a refund. but they likely won't let you get away with that so since they did say you could swap for the 55cm you must take them up on their offer.

good luck...you're gonna need it
