Anyone not use a mtb for bikepacking trips?

[Zippy]

Looks like the MTB equivalent of a leaf spring!

It's obviously acting as a spring Zippy but I was more concerned about the size of the side cut-outs used to 'tune' the spring ... there's not much material round them.

Without knowing the actual material properties of it, I can't really comment on that. You'd hope for some proper maths/engineering and Quality Control on and item like that I'd also be fairly concerned here about different metals in potential contact with each other and the associated galvanic corrosion that can occur.

I think it's quite neat, but definitely agree you have to think twice about it and do go "eeeer"

It makes me think of early 90s "innovation", didn't Merlin Metalworks do something like that but with a proper swingarm and a carbon tube? That or I daydreamed it during GCSE Tech lessons as a teenager.....

There's a chap in the current magazine of the Fell Club recently done the Wayfarer's Pass in the Winter on a Brompton.

Can see me using my tripster more and more where more distance / less tech down is involved
