Sorry if this is in the wrong place...
I have a LOOK KG241 which has a Shimano Ultegra Flightdeck groupset. Bike just won't shift from the small ring to the large ring on the crankset whilst on cylcing. However when i put the bike on a workstand and spin the pedals with my hands, it shifts perfectly... The general shifting isn't exactly lightning quick but is pretty smooth and is fine shifting down from the large ring to the small ring.
Anyone know what might be causing this?
