I have noticed that I can not get my rear derailleur to sit perfectly allowing all of my gears to feel good. Mid range often feel a bit lumpy or there good when using either one of the front chain rings but not both.
I clean the chain once a week and I'm always fiddling with the cable tensioner screws, more than I think I should be. I recently replaced the gear cable.
Is it likely that I need a new chain already, the chain rings are a bit worn, not sure if too much and occasionally the chain seems to slip when i pull off (mid range gears)
I just had the bike on a stand the back wheel is making a creaking noise when i spin it and the cassette has 5 to 10mm wobble, could this be causing the issues & should there be that much wobble on the cassette ?
Also the Gear cable is frayed again - I only changed it 2 months ago.
