I'm thinking that this is a USE post but it doesnt have elastomers so not like the ones online.

If anyone does know. Can you advise me on how to load the spring back in! it has a lip inside the tube that i can't get the spring past....

Thanks in advance!

I'm only going to be a bit helpful, and then not much. I don't think it's USE. They have a rubber concertina, a smooth collar (this one is far chunkier and knurled), and as you say, USE used little bobbly elastomers. I'll have a think....one possibility is an early ZOOM copy of USE.

The top part is USE, the elastomer could have been replaced for a straight spring.

I don't k ow much about them and half of it always seem to have bellows covering it.

Ah one thing - what's the diameter of the post?

The shim says 27.0 will have to measure the post...

I have NOS USE post here - which does have the knurled collar, also have another which doesn’t, so probably just a design change.
I’d agree that the spring is non-standard though, pretty sure the ones I have only have the elastomers.
Did you dismantle it? I.e. are you sure it’s supposed to go in there?

Post measures 25mm. Ta

Hmm a t that diameter maybe USE after all, if once a hero has one with a knurled collar - so the spring may indeed be after market.

I took it apart and the spring came out pretty easy. I just can’t get it back in past the lip (1/2 way down to tube) so that I can re fit the cap! The spring sticks out approx 3cm
