Full proper adjustment of a TDF takes about an hour of iteration. There are many tension variables for the chain. It is well worth getting it right.

As to the travel, there is a threaded collar that adjusts, if I remember, the inner throw and the outer is just the limit of the mechanism.

It is best to let some kind soul at the Cirque set this up for you. I have no idea how French bike shops looked their customers in the eye and charged them for an hours labor to get their TDF just right in the 1950's.
