[Closed] Odd dropper question

Any suggestions?

New frame

Applauds slowly*

*singletrack sarcastic standard response response

No more sarcastic than the question demanded really - how can you have a freely sliding dropper where you're relying on the tube its dropping through to provide structural support for the frame

Defeats the object really - no dropper is made to take those tolerances and if you're relying on the seatpost to support frame integrity then you really need a new frame (or for a better repair on the existing one)

Just cos it's not what you want hear doesn't make it wrong

Seriously. Droppers mostly aren't cheap, I'd spend the money on a sound frame rather than a dropper that can be clamped mega tight.

or get a proper repair on the frame (as said above)

Really can't be bothered to explain the semantics of why a further repair isn't possible and the double clamp solves the issue.

It's a spares bike I've built around a Cotic Soada not one of my other 5 "decent" bikes... so new frame isn't needed, It rides great with a normal seatpost. It's only really for taking my daughter out in the back.

I would like to fit a dropper to it but the only way it will work is if I can clamp it tightly.

If there are any clunky older manual ones anyone can think of that fit the bill then please let me know.

When you mean double clamp do you mean one that clamps the seat tube and the post or just the seat tube albeit twice?

My Reverbs are really sensitive to pressure from the clamp. Carbon paste is your friend.

Seat tube twice. A bmx clamp.

Yeh I know a reverb or ks won't work.

Carbon paste won't help it's not a slipping issue it's a creaking issue from a second crack that can't be welded. With the double clamp the crack is supported and the lower clamp part is below the crack completely. Can't be welded or then you can't get the clamp over the weld.

Rides spot on with the double clamp and a rigid Seat post. I'll just ride it with the fixed post if I have to but thought I'd see if anyone knows if any of the older manual ones are a bit more industrial... I've got no experience of them hence asking if anyone knows of one that can take a bit more umph on the frame clamp?

Gravity Dropper may be a little less sensitive to clamping force, or a cheap RSP thing.

You laugh, i give it a year or so & they'll be back.

If you over clamp a dropper you might end up causing permanent damage resulting in having to buy a new dropper.

Get a cheap one off ebay like a Tmars and try it. Tmars is just a spring in a tube with some holes in it and a pin that pulls in and out of the holes.
I would want to be forking out on a fancy one, if it doesn't work you can hardly return it and it might not be any use on another bike either.

What Joe has linked to was what I was asking if you had already.

If the clamp is deep enough and clamps the creaking crack then it could be a option?

Tmars looks like a good shout. Cheers for the suggestion ads678

Joe G. That's exactly what I'm running... and it has to be tight to stop it creaking

Hence the original question lol

Edit, just 're looked at that tapered clamp. That's not what I'm running. I'm running a double 34.9 twin bolt (double depth) clamp from a bmx

There's an Orbea dropper that might work - definitely a lot more mechanical than the others (if you can get one)

Chilled, that tapered clamp might mean you can run a dropper without over tightening it?

I had a gravity dropper ages ago and ran it in a frame that everything seemed to slip around in. I tightened it proper tight and it was fine. Really really agricultural by current standards though.

If its only for taking your daughter out on the back - why bother with a dropper?

I found my Gravity Droppers wouldn't work if clamped too tight. I'm not sure any droppers will - they're made to be reasonably light yet strong enough, so the tube walls aren't stiff enough to withstand a high clamping force without ovalisation.
