Got up early and went to the Bristol track and did some 90% laps. Managed to go 1 second faster than last week even though it was raining and the track was wet and sticky.
I took this to mean that the new gearing was better so I went to Crucial and bought a new profile elite 18 tooth freewheel as the Shimano one I have been using to test is a bit crappy. My old 17 tooth freewheel engaged really quickly but the 18 tooth one is really slow to engage and it feels like the chain is loose even though it isn't. Also the Shimano freewheel is silent which is really strange.
The profile elite is supposed to be the best freewheel that you can get and it has 140 points of engagement that makes it instantly engage. Apparently it is the equivalent to a cassette hub and much lighter. It also makes a really loud noise like a cassette hub.
After Bristol I went back to the Bath track and practiced the last 2 straights. I think that I have it pretty much dialled. Tomorrow I will practice on the first half of the track to try and get that dialled too.
