Chain slipping changing gear uphill, New Campagnolo Groupset
Have just bought a new group set, campagnolo Athena. Had it put together on my frame by my LBS. However when im putting power on the pedals or going uphill and change gear the chain slips before catching the gear. This happens whether im changing one gear at a time or whether im changing 3 gears at a time. I thought Campagnolo was meant to be smooth shifting, with seamless transition from gear to gear whether with load or not!
