Seat post clamping

[neilrichardson55]

has anyone come up with a better idea to clamp the seat post, think mine is coming up to needing to be change. its starting to move a small amount
i have been looking to see if there are any ideas for modding it ? not seen anything yet

Use a hex key clamp and forgo the quick release.

Time for a new sleeve insert

Modify a commercial seatpost clamp to fit on the seatpost. It's easy, though it means an extra clamp.

Seatpost clamps work really well. If you're getting a little slippage then tighten it up a little - having decent hex wrenches will make a difference.

I also usually put some Fibre Grip on the post, even on an alloy frame/seatpost as it adds friction and helps prevent movement.

I think the OP has a Brompton, so may have specific requirements incompatible with methods used on other bikes.

It’s in the folding bikes section, my response was Brompton related.

Indeed - but other suggestions were probably more suited to non-Bromptons

If a brommie you likely just need to turn the nut slightly. But still make sure you are closing the clamp via the camming action.

and if this doesnt work, then its time for this. if it keep slipping down don't keep tightening overwise you eventually damage the frame.

its relatively cheap, but needs a specialist to do it with the reaming tool, Apps Cycle works https://www.appscycleworks.co.uk/ are reliable as close-ish - he's done this job on my brommie

new sleeve borrowed a hand reamer and had not so much fun getting the old sleeve out, but done and reamed out holds the seat post much better hope it lasts

There's an issue with over-tightening it. You'll eventually damage the frame.

Tighten it a bit or maybe scuff the seat post to create more friction, but essentially, once you've reached this point, you probably need a new sleeve.

I had this. I bought a non-OEM clamp and filed off the lip so that I can clamp it to the post to sit above the Brompton one. Adds a little bit extra stopping power.

In the end though, I needed a new sleeve, and a new seatpost as mine was bent. I've left the additional clamp on though.
