Was only suppose to bleed my rear brake line. They told me that air in my hydraulic disk brake line was 'normal' for shimano (which is a lie)...got the bike home and realized my brand new rear disk brake pad ($27.00) was replaced with an inferior pad....and my front and rear derailleur stop screws had been readjusted badly; also, the indexing was way off. They also charged me $10 more than quoted over the phone. Life is too short. I walked away. No moral or ethical character at this shop. Take your bike else ware.
