Overheating woes

[Azzman1000]

Ah, so the 43mm one is standard and a 50mm one was the hot climate option that was fitted in Australia?

Thanks for the link. It's a shame the one in Australia is 70% more expensive than one in the UK.

Just be aware that the one from the UK, (I assume you’re talking about the Forst brand from heritage parts.) is possibly only a 30mm core but I can’t confirm.

Also shipping from the UK can be frightfully expensive.
