- Odd dropper question
Got an odd requirement
31.6 dropper post that is at least 400 long
That you can clamp really tight without loss of performance. Really tight!
I’ve got a re-welded to frame that had cracked near the seat post. I’ve added a double clamp and need to really bolt this up tight to retain support.
Any suggestions?Posted 2 years agotmb467Subscriber
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)

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.Posted 2 years ago
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?Posted 2 years agoads678Member
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.Posted 2 years ago
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.slowriderMember
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.Posted 2 years ago
