    Seat Height Blues

    I have been having problems retaining seat heigth. I ride a hardtail with a Race Face Evolve seatpost with a Hope quick release clamp.I'm thinking about changing posts or taking this post to a machine shop and having it "knurled". Are there any seat posts out there that are knurled or grooved? Thanks to all you fellow Clydes out there for any comments or suggestions.

    Start by getting rid of the qr clamp! That is not the place that you want qr(unless you like stealing other peoples seats and posts)!

    Thomson posts have ribs which seem to help. Also, they are the best post on the market in every other way.

    How tight is your QR? The only times I've had a post slip, qr or bolt, it was slightly undersized - typical of real inexpensive posts.

    The grease that is used to keep the post from sticking in the seat tube is also slippery. Years ago, someone mentioned using chalk instead of grease; the dry kind, not greasy crayons.

    "it IS possible that you are faster or slower than anybody else who is having at least as much if not more or less fun"

    I have been reading about where riders have taken an aluminum soda can and made a "shim". Any thoughts,pros or cons?

    Have you lubed your QR clamp recently? If you haven't, put a bit of grease or chain oil in there. Chances are it is too loose, but the friction is making it feel super tight. Creaking is also a sign that it needs some lube.

    My evolve slipped like mad in my sir9. Truvative team post has been better, but not 100%.
    I know what you mean by qr so tight that it's hard to close/open.
    Sometimes I think it's a seat tube issue. Gonna try fiber grip next which is usually used for carbon fiber and aluminum contact.

    Friction paste is what you need.

    Here's a brand. However, your LBS has some for certain and they may just put some of therir's on your peat post if your a return customer...

    Yes, that's more like it. Any other experience using this successfully?

    I replaced a useless Hope QR on my 135# wife's bike recently because it slipped all of the time. It was replaced with a Salsa Lip Lock, same as this 230# clyde runs, because it won't slip

    Dont waste time or money....

    Hey Pop,

    Just wanted to let you know that the seat on my Haro came knurled stock and I still have slippage. (About an inch per 2-3 hours). Not bad but still annoying. I did some research and even if you replace your QR with a post bolt you will still have the same problems. (Face it, we are clydesdales, right.) I have also heard that checking your seat post pre-ride for any small pebbles that may be acting as a bearing will help. I read that rubbing dirt and baby powder on your seatpost may be effective short-term but you run the risk of your seat seizing in your seat tube. I am going to try using an aluminim can as a shim. That seems to be the most cost effective solution that I have come across. Give it a whirl! Ride Hard!
