I think he's looking for durometer on this side of the pond.
If someone knows the durometer he'll be able to convert it to shores.
Jen, Cycle X, USA sells replacements, but shipping might be a witch.

Prosperity to all in 2019

I have let them do 2 hubs for me.
It's very convenient to get the job done by them. For a fair price too.
Return shipping to Sweden was 15€ 3 years ago. Shipping to them almost double.
Rivet the primary hub need experience to be sure to get it right.

OK...thanks for your help. But still interested in the quality of these rubber parts.
Are they all the same or everybody has different...Hmmm
Motorbiking in Sweden would be great 😀

It was a wonderful bike season last year. Let's hope 2019 will be good too.
Send an e-mail to Ralph-Peter Nagel about the rubber quality. Like how many hp it is OK with
nagel@fourever-classic-parts.de  No problem to write in English.
He provide engine tuning up to 93 whp so the rubber must be OK with that in the long run.

I emailed these guys the other day but they no longer send anything to the US because customs suck. Their kit is much cheaper though than cycle-x. I will just disassemble mine and get a kit probably from cycle x and put it together.
