[Applause] hi my name is al and today I'm going to show you how to solve that sinking feeling if you've got a slipping seat post if you find that your seat post is slipping when you're riding don't just crank the bolts in your seat clamp even tighter what you need to do is make sure that everything's prepped correctly and we're going to show you how to do that right now a rag carbon fiber assembly compound grease a torque wrench some allen keys over tightening your seat clamp can not only damage your frame can also damage your seat post itself first thing to make sure is that you've got the correct sized seat post to 2072 frame and the 2072 post they have to match otherwise it's never going to work if your post is slipping let's start with the basics take things apart and do it all properly so we're going to undo the clamp this seat post clamp has two bolts which helps to spread the load with that loose you may want to mark your saddle height first by the way bear tape works wonders there we're going to remove the seat post and saddle from the frame so here's your saddle in your post and you see clem first part of this is we're going to clean everything so clean around the top of the seat tube the slot of the back and as far down inside the tube as you can do the same to the post there's any grease it might be a good idea to use a bit of alcohol or some degreaser to make sure that this is completely clean one thing that you should note is that you should never ever use grease on a carbon frame or a carbon seatpost because carbon can absorb the grease and it'll cause it to swell which which will damage it also pay attention to the c-clamp give this a good clean and we're going to remove these bolts over time these bolts will get covered in grit and may become rusty from all the water and road debris that's getting thrown up by the bat wheel so we're going to remove those and we're going to clean the threads give the threads a good clean it helps to have a toweling kind of rag here gets in between all the threads really helps to get them good and clean if you can also remove the threaded inserts in your seat clamp remove those also you can see these are pretty gritty and we give those a good clean as well clean inside where those threaded inserts sit in the clamp to get rid of any grip with the grit gun these bolts are less likely to bind we're going to grease them as well and it'll really make the most of the tightening talk do you put into the bolt if these are all corroded and rusty dirty then as you turn them not all of the talk that you put into the bolts going to be going into actually tightening the c-clamp put the threaded inserts back into the clamp and refit the bolts okay next we're going to refit the seat clamp here we got a carbon fiber frame so in this instance we're not going to apply any grease here if your frames made of metal so Tigh alloy steel it's a good idea to apply some anti-seize compound to the outside of the SI tube align the clamp correctly and regardless of what your seat post or frame is made from if your seat post is slipping this is the stuff to get some carbon fiber assembly compound basically got small bits of grit or plastic beads or whatever they are inside the gel and as you tighten the seat clamp these will help to to grip the post inside the frame so be much less likely to slip he also helps prevent it from seizing inside the frame is obviously a great consideration we're refitting the seat post lots of excess assembly compound they're just going to wipe that off and once we're happy the saddle is aligned correctly we're going to tighten the bolt on this seat clamp we have a talked saying this is pretty common however this is one place I recommend not following the talk saying you probably see that you have a maximum torque setting so this bottom bolt is rated to 5 Newton meters some clamps will go much higher than that but often you don't need anywhere near that talk as long as you don't exceed the talk what you're looking for is a solid post that isn't going to slip when you're riding so all we're going to do is we're going to tighten the bolts this lower one's rated to 5 Newton meters so it can be a bit tighter than the top one which is just a couple of Newton meters so we're just going to nip that top one up bit tighter on the bottom if you're unsure of torque settings then use your torque wrench set the bottom onto three top one to one you know stop from there see how you get along see how tight it all is and we're nowhere near talked there and that's absolutely solid so you're not going to have any issues with slipping if after you've done this you still find your post is slipping you've checked everything then maybe get yourself one of these double clamps it really does help to hold everything more solidly so that's it that's seat post is going nowhere and you're ready to hit the road thanks for watching see you next time [Applause]
