A video showing the first half of the Seagull Run in Swinley Forest on Sunday 27th May 2012. I was pretty much tired at this point, made a few mistakes, but am reasonably content with this run.
The conditions were dry, a bit dusty, with some muddy holes dotted around (between Star Post 6 and Lower Star Post).
The Squirt lube kept the bike chain very clean and well lubricated; running smooth. See photos below of the untouched chain after Swinley.
There is some build-up of wax on the jockey wheel but this does not interfere with the chain. Any dirt that is stuck on the wax will likely be shed. If I had used my normal wet lubrication then this chain would have been quite messy, with the oily-dirt mixture grinding the chain. The chain is a Shimano 10-speed HG-X (XTR M980).
