LEFT-HAND DROPPER LEVER
For those unaware, there’s one more thing to consider if you want to use a dropper post with this or any left-hand drop-bar lever: you need to have a dropper that uses a barrel-shaped fixture for the cut end of the cable on the seatpost side (shown on left photo above, to the right). These are fairly simple; they clamp onto the wire using a worm screw and then sit within a hook on the dropper actuation mechanism at the bottom of the post. The built-in cable nipple—the cylindrical-shaped metal head that’s affixed to the cable—remains seated within the lever and is used to pull the cable, so you have to attach the barrel fixture on the other end to pull the dropper actuation mechanism. I used a PNW post, which comes with one of these—and there are other brands that work this way, such as Trans-X—but a lot of droppers are designed to use the cable nipple at the post end (shown on left photo above, to the left). Note that there are ways around this as you can buy a “knarp” cable barrel from several companies, such as this one from Wolf Tooth Components. You just need to make sure it’s the right width and diameter to fit your dropper. You’ll also want to install an inline barrel adjuster at the front before the housing is routed through or along the downtube.

What kind of saddle bags can I use with the ShockStop Suspension Seatpost?
Most standard strap-based saddle bags will fit the ShockStop Suspension Seatpost without issue. If your saddle bag uses rigid clips, clamps, or some other inflexible attachment method, it's possible that your bag may not be compatible.
Any bag that just attaches to the saddle or just attaches to the post is fine. But when you attach to both the post and the saddle you need to account for the relative motion of the saddle to the post. This means that if you cinch down the bag when off the bike it might have some movement when you get on the saddle and compress the post a bit - this might not be a problem but it might be something that is an issue.
It all really depends on weight and how stable the bag is and if it is attached to both the post and the saddle - it can be fine but with a lot of weight it will mean it can move around when the post is compressed. It will likely come down to testing it out with your specific bag to see how it works. And if you have a bag that is able to be secured to just the post or to the post and a rear rack then you will be all set.
