Here are the basic parts of the Sweetpost: a titanium tube with a welded on top tube with notches, an aluminum inside plate set with notches and a slot for saddle rails, an aluminum outside plate set with a slot for rail, and a bolt. The plates (aka caps) notches mesh into the top tube notches’, giving rise to a micro adjustment system. If you play with the system a lot the soft aluminum parts can wear a bit against the harder titanium, so you may need to replace the caps at some point in time?
Installing the Sweetpost is incredibly easy, and can be done in a very short period of time. Start to perfect finish in perhaps 30 seconds, give or take. Rotating and sliding the saddle is done with a simple 5mm hex key on one side of the seatpost clamp, and small angle adjustments can be done due to the ingenious micro notch system.
Just attach the inside plates’ with the notches inward, meshing with the seatpost notches, and align the plate’s slots, with the slots on the top. Slide the saddle rails into the slots starting from the rear of the saddle, and push the saddle backward to a rough desired location.
Roughly center the saddle in the slots, both in rail and angle positions. Attach the outside plates with the slots inwards onto the rails, aligning them together.
Insert the bolt into the proper outside plate hole, and slightly tighten with a 5mm hex key. Slide the rail into position (fore or aft), and rotate the saddle to the desired angle, and then tighten the bolt to 12-15 NM of torque. Done! If any minor adjustments are required, just loosen the bolt and move the saddle as needed, the micro notches keep things stable so that the saddle won’t flop around while adjusting or tightening.
