Hi,
Im dabbling with 1x9, where does everyone aim to put their chain line at?
My chain line at the moment is 50mm. This puts my chain line straight in 6th gear. So my chain line is biased towards the hard end of my cassette.
5th gear would be balanced top and low. 4th would be biased to low.
Should the chain line be biased to where you spend most of your time?
Or
Where there is most force acting on the chain?
I expect during my riding routine im applying most force to the drive in the hard end of my cassette, when im standing up, mashing the pedals.
I think im applying less force in the easier gears, as this is when im sitting down spinning. This is also where most teeth are meshing with the sprockets, spreading the load.
What are peoples thoughts?

it comes down to where you run it most of the time.
5th is good."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

It makes best sense to have it in the middle at 5th, unless you only very rarely use the largest cog! If it really is rare, 6th shouldn't be a problem.Trek Madone 3.5 (RS80s, Arione)
