I dont know if anybody has experienced crap service from a bike repair centre. Im shocked i went to my local bike repair shop to service my front mech shimano 105.The mecanic said hed repaired the mech and serviced it i rode my bike home but the problem was still there. I rode back the following week and showed the cybotech trained technician. He took the bike for an hour and and i returned he told me had had solved the problem but it just got worse so the front mech wouldn't work upon further inspection i noticed the plastic sheath near the handle bars had a huge split down it and the gear cable had frayed within what a shock. Cybotech mechanic.. My backside a first year rookie should have spotted that. Im now taking my bike to another centre. I guess service is questionable these days.
