Adjusted Saddle, now trying to do me an injury

So I had a wee fiddle with my saddle the other day, just to change the position slightly. Got it how I wanted it, all happy, set off, but after a few miles the whole thing slipped back on the bolt to the seatpost and angled itself up quite a lot. Not comfortable on the old censored .

So methinks, I just didn't tighten the bolt tight enough, reset it, tighten it up (using allen key on a multitool) and off I go again. Same thing happens.

Ride it for a day pointing skyward, get home, bust out the big proper key and tighten it as hard as my pathetic girly arms can achieve.

Lasts for a few days but is gradually slipping again.

WTF is going? I'm a big guy, about 95kg, but I've never had this problem before...

    Some seatpost clamps can be prone to slipping, or require a good old heave with a big allen key. Multitool might not be giving enough oomph. I'd take it all apart and make sure is clean.

    We saw similar recently and the clamping bolt was bottoming out on the saddle so not clamping the rails properly......

  • Thanks guys, seem to have sorted it by taking the saddle off and cleaning the clamp.

    if you keep having this problem then a 2 bolt clamp could be the answer, it's a better engineering solution and if you're putting a lot of 'leverage' on it then it's much less likely to slip or fail. Something like this for example:
