Swinley Forest

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.

Swinley Forest, Seagull Run

The conditions were dry, a bit dusty, with some muddy holes dotted around (between Star Post 6 and Lower Star Post).

Squirt lubrication

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).

Whatever the weather, whatever the trail conditions, I’ve always used Finish Line’s “Wet” lubrication on my bike chain. The Wet lube is great in wet conditions but is a bit gooey, much like most other oil-based lubricants, so has a tendency to pick up dirt especially in dry conditions. Now, dirt isn’t something that you want on a chain as this can cause increased wear through grinding, so I tended to degrease the chain and re-apply the wet lube on a regular basis; messy, really messy.

Of course over the years I’d heard of other chain lubes called “dry” (based on PTFE, or wax for example) which have been formulated to be less sticky than wet lubes so don’t accumulate dirt as much, but they do have a tendency to be washed off in the wet. Hence the word “dry”; use in dry conditions. So I resisted the temptation to try dry lubes for a long time.

Frankly, I was getting increasingly tired with the degreasing routine, so I kept an eye out on the market and finally decided that this year would be a good time to try a dry lube. I went for Finish Line’s “Dry” lube based on Teflon (Teflon is DuPont’s name for PTFE). However, before I was able to try Finish Line Dry lube in earnest I came across Bikinventions’s wax-based emulsion lube called “Squirt”. Squirt has glowing reviews and it appears that it has better resistance to being washed-off than other dry lubes.

I couldn’t resist! I managed to get hold of some Squirt and applied the gloop liberally over a freshly degreased chain (twice, actually, as per instructions for the initial application). Once dried, the lube is largely transparent. I’ve done a couple of minor rides in dry conditions and it seems to be doing well so far. I’m very pleased actually. Any dirt that sticks to the wax is quickly removed as the wax sheds, so there shouldn’t be any need to degrease or clean the chain.

Time will tell how well it does; I’ll provide updates on this blog.

Science-Based Medicine describes the failure of acupuncture to evidence its claims of efficacy and that, despite this failure, acupuncture is increasingly popular with the general population, seduced by its apparent plausibility and its apparent antiquity.

There comes a time when it’s clear that only the delusional or the deceitful claim evidence for their case when, in reality, said evidence indicates the opposite. Homeopaths and proponents of homeopathy have exhibited such delusional/deceitful behaviours regularly. The Quackometer and Zeno’s Blog describe the most recent of these behaviours:

Greta Christina has posted an article on why religion should not have special privileges.

I’ve long argued that religion should be mocked and criticised, that religion should not be protected, and that it has long abused its barbarically-acquired privileges.
