    Bike seat issue

    My issue as of late is my bike seat keeps slipping down. I took my bike in for a "check up" after my chain broke a couple months ago, and since then it has been an issue. Sometimes it is not even going a half mile! Thoughts? Suggestions?

    Thanks,

    what kind of frame material, what kind of seat post material? Do you have one of those quick release flip levers to secure the seat tube or do you have a nut and bolt?

    I'd say torque the seat post (and by that I mean with a torque wrench, not crank on it as hard as you can) and consider using carbon assembly paste to provide some friction in there.

    Your best bet is to visit the shop that gave you the tune up and ask them to deal wit it. It should only take them a few seconds.

    If all else fail you can use Valve grinding compound, you can get it at the auto parts store..Not sure if it is the same as carbon assembly paste but it will also provide friction. I use it when i need to tighten or loosen a Torx or Allen head that is a bit worn out...

    It happened to my spouse on one of his bikes. He ended up buying a heavy duty seat post clamp without a quick release. It worked perfectly.

    This is the bike, only thing I changed was the pedals and the seat. http://www.raleighusa.com/archive/20.../detour-45-11/

    I say your shop didn't secure the post properly. They loosen the post then extend to clamp on to the bike stand.

    Kind of scary to think but the shop guys can be real lazy at times. No really, they can be!

    I've gotten back my bikes before with seats pointed 45 degrees of center a well as some slipping.

    I rarely take my bikes to the shop anymore but when I do, I make it be know I don't want them loosening my seat post clamp on the frame.

    A quick release is not a wing nut, you flip the lever to lock it down, don't spin it to tighten it down.

    Same with quick release skewers for wheels too.

    I had a terrible time with the seat slipping down on mine and I saw in a bike forum where somebody suggested putting chalk on the seat post. I tried it and lo and behold it hasn't slipped since.

    Chalk? I use a strip of black electrical tape around the post. Leave a small gap and if it vanishes, something is wrong.

    Mine have just needed some scratching-up with some sand paper to offer something for it to grab on to. Pretty common.

    Seatpost: Alloy Micro Adjust Bootless Suspension 27.2x350mm

    Ditch the suspension seatpost and go with a solid 27.2x350mm seatpost. Suspension seatposts and clydes don't go well together. I know.

    Get yourself one of these in 4/5/6
    http://www.amazon.com/Park-Tool-AWS-...y+allen+wrench

    and stop before you have to adjust your arms for more strength (Broken 3 bolts in the last 4 months)
