i've noticed most lbs here do not like people with fixed/ss bikes. the other day i asked my lbs about a 48t chainring for my fixed and the two guys working there went off about how trendy and lame fixed is and how there are absolutely no benifits to riding fixed and how i would never find a 48t chainring because people only ride 42t or 52t. others mechanics automatically get a bad attitude as soon as i mention that my bike is fixed.
