I made a tyre swap on my fixed gear commuting bike yesterday in preparation for winter which is due to arrive any day now. Autumn is still cruising along in Edmonton but the leaves are mostly gone and we’ll have to give up on pretending that it’s still fall when things turn white.

I swapped my old chain off for a new one as I had stretched the old one by 3.5% or so. If you’re not familiar the rule of thumb is that you’re supposed to replace it around 1% I think. An eighth of an inch over a foot. 1/(8*12)~1% it was making quite a bt of noise due to being too long and not fitting well on the front chainring. I also slapped on the winter tyres which are 34mm front and 36 mm rear. I’ve a sweet c-cross front tyre that runs between 60 and 90 psi with loads of little knobbies. It’s quite fun and at 80 psi makes a sweet hum as I fly down the pavement. I also swapped gears for winter and am running 48×20 instead of 48×17 which was my summertime gear.

I also caught wind of a funny product out of Denmark to make cyclists appear a bit more fashionable. I would wear one if I had it but I don’t think a third helmet acquisition is necessary in 2008, plus I’m sure they’re not cheap.

Other news is that I’ve been in the pool 3 days in a row totaling up to 5 kms which is pretty amazing progress for the shoulder. It’s nice and tired after about 30-40 minutes in the pool. I skip doing the physio exercises when I’ve swum, I think it can only take one workout a day.
