Booked bike in for silver service and ordered Ultegra 6800 calipers to replace my existing Tektros. Bike returned with my Tektros still on the bike and they tried to charge me for actually fitting the Ultegras. Wasnt the shops fault as the bike is sent away to the service centre so they are at fault. They even informed me the calipers would take a day to come in stock. Main reason for service was front tyre shaking on descents and no notes in regards to my concerns either. Best bet is to get your bike serviced elsewhere that dont charge you for labour they DIDNT do.
