I'm a real novice at this so please make allowances! I was having trouble (front derailleur) shifting up from first to second. When I flicked the shift lever into 2nd, the cage would move across seemingly correctly, but the chain would struggle, make a lot of noise and refuse to shift up. If I pushed the shift lever over a little more - towards 3rd - and held it for a couple of seconds, the chain would move up on to 2nd position and stay there OK. I tried to correct this by increasing the tension a little on the shift wire. The result of that was that it shifts up to 2nd correctly, but won't go down to first. I thought, well OK, I must have over-tensioned it. So I released a tiny bit and retried - only to find I'd gone back to my initial position. I've been doing my head in, several times over increasing and reducing the tension, but I always end up with one problem or its opposite. What am I missing? Any help appreciated.
