Travel adjustment on Rockshox forks?
Hi all,
I'm looking at the internal travel adjustment for Rockshox forks, where there's a bushing that can be added/removed for setting up the fork. And the part that I can't figure out is if the adjustment is on the "upper " end or the "lower" end.

Will a fork set for 80 mm travel have the same axle-to-crown as a 100 mm, but bottom out faster?

Or will a fork set for 80 mm travel have 20 mm less axle-to-crown as a 100 mm, and hit full extension faster?

(the above assuming that pressures and sag are set up correctly for both forks)

On adjustable travel forks, the longer travel position has the fork crown sitting higher when uncompressed. On older RockShox models I've worked on, shortening the top-out spring/bumper allowed them to telescope out farther. Then it was a matter of adding spring/air/elastomer to the compression side.

I got the bright idea to google axle-to-crown, and according to that the long travel axle does ride higher. I hoped for that, but mechanically it could have been either.
