CONTACT SWITCH AT DROPPER SEATPOST

RIDE WITHOUT LIMITS

The redesigned Contact Switch AT dropper seat post features more insertion, more drop and better fit for more seat
tube designs than ever before. With travel length and cable routing adjustability as well as a wide choice of remote lever
options, the all-new Contact Switch AT offers the rock-solid, play free action you expect and the versatility you need to
handle technical terrain.

MAXIMUM TRAVEL, MINIMUM LENGTH

With 30mm of tool-free adjustable travel and
a shortened chassis for each post length, the
all-new Contact Switch AT Seat post fits a wide
range of rider heights and riding styles as well
as frame sizes and suspension designs. Insert
an individual or combination of 5, 10 or 15mm
spacers in the seat post collar to easily reduce
travel and store unused spacers as backups at
the bottom of the post.

ADJUSTING TRAVEL

Remove the post from seat tube to access travel spacers at the base of the post.
Take out the travel spacers.
Place the post back in seat tube without tightening.
Press down the remote lever to drop the post at least 40mm.
Unscrew collar ring assembly.
Gently tear off desired number of travel spacers along the tear lines, and install travel spacers under the bushing. Make
sure the spacers sit securely inside the bushing groove.
Screw collar ring assembly firmly back on the seat post.
Pop the saddle back up to the new maximum height
