Using Shimano Nexave ST-T400. Can select small and middle chainring but when trying to select large chainring, the selector lever moves without any 'feel' (almost like the cable is loose - but it isn't). Only at the very limit of its movement does it feel like it is moving the cable. The derailleur does move but only a very small amount and not enough to engage the front chainring. I have read the threads and watched the videos. H - L screws are all OK. cage clearance is fine. barrel adjuster is set according to videos etc. I am totally baffled. Anybody got any ideas?
