Mel's Tech Tip - How to Measure Your Seat Post

Remove your seat post from the frame then take a rag and clean off all dirt and crud so you can read the numbers. Check size using caliper tool. If you don’t have a caliper tool, you can always use a “poor man’s” caliper by taking an adjustable wrench and use it like a vernier caliper. Once the wrench is open to the correct size, measure the opening with a metric ruler.

When you are ready to reinsert seat post make sure you grease the post and the seat tube. This does not apply to carbon.

After you ride in the rain, make sure you pull both your seat posts out and check for water down the seat tube. Turn the bike upside down and watch for any water coming out, if you see any, dry out your seat tube so it does not damage any other parts.

Shock Absorber Seat Posts

Most Shock Absorber seat posts require a shim. If you pull out your present seat post, it should be stamped on side near the bottom.
You will need at least a 4½” inch seatpost showing.

All Elastomer shockposts should be lubed with either White Lightning or Pedro’s Ice where the shaft enters the post to ensure best results.
