Hi all,

So I'm doing Fuji Hill Climb next week and the cassette I currently have on my bike is a tiagra 9 speed 12-27.

I'm not sure I'll be able to get up on this, so I was wondering if anyone happened to have anything bigger I could borrow?

Preferably 30/32.

I'd be enormously grateful.

Cheers.
