Upshifting issues (in the front)
I've put together a bike on Nashbar Touring frame and I have an issue with from derailleur.
The derailleur is Tiagra, and the crank is Nashbar Trekking crank (48/38/28)
Everything works ok, except:
When upshifting from middle to large, chain "binds" between derailleur inner plate and large chainring - so there is high resistance for rotation of cranks - and when I "force" it through, chain is picked up by large ring and everything is normal from that point on.
The derailleur is adjusted by Shimano instructions... I can't figure out what's wrong. The only thing that I suspect is that it's too low on a chainring.. but it doesn't appear so. Could that cause this kind of behavior ?
I'd really appreciate some advice on this
