New tyre fitted on my Eastway tonight, new tyre on the front and old front tyre fitted to the rear, rear tyre scrapped, it was well squared of but had a little life left. Was going to fit a new chain and cassette as well but the new chain, 10 speed, came without a power link, it just had a pin with it, something I hadn't seen before, and I haven't got a spare link so I've ordered two power links and will fit the chain and cassette when the links arrive. I also noticed the rear wheel bearings were rough so I'll have to strip and grease them whilst I'm working on the bike.
Edit, I've been online and apparently the pin is the usual way of connecting shimano chains, its just that I've been buying sram and KMC chains for the last 10 years and hadn't seen it before.
