Really like the hook/pigeon type move at 1.02.
The blue sky Porthcawl rock footage was ace. Dunno why but I laugh at the hop style at 1.21 across that section.
Regarding Porthcawl. I find it really harsh to ride. Have to run hard tyres to stop punctures but the bumpiness of it makes it horrible to ride with high pressures. Annoying.
I can remember watching the narrated version of, I think it was Manifesto (don't think it was Crux (I have no life)), and Ryan Leech mentioned this exact thing. I raised my eyebrows and nodded my head in agreement.
Bob MacGregors Trials Academy in Glasgow.
There's also a bit at Glenmore Lodge in Aviemore. These are 'official' places to ride. If you're just talking natural spots, well, there's a lot!
Na, your chain looks fine. Just take the pin out and have the arm running parallel with the chain stay. The arm with the jockey wheels will drop a little but should be ok as the spring is solid.
