bigggggg legs , feel the quad burn
fair play , thats a good road gear
its not chainline , if it was it would drop the chain . but to check take the chain off and run a piece of string from teeth to teeth ( you can wrap it around them ) and eyeball it from getting behind the bike , much easier to get it precise once the chain is out of the way
itl be the rear sprocket , only 7 of those 15 teeth will be engaged at the best of times , the large chainring ( most ss use a 32/34 ring ) will be putting the chain at a bigher angle and the tensioner pulling it further away
it tensions down because thats the way the spring is wound , it wouldnt work very well making it push up without changing the spring for an opposite wind . i wouldnt be surprised if they are a common spring and the opposite is harder( more costly to get old of )
but id hazard a guess the spring is the same as from a ad990 . if i get bored ill take one apart
a pic would help but for now drop the chain off the chainring , loosen the tensioner and turn it clockwise ( back ) and retighten , thatl add more tension to it so will push more chain onto the teeth
