Fixie!!!

Today was my first ride to work on my Sun's new bike. This year my bike to work bike I have chosen a single speed fixed wheel bike. Fixed wheel bikes are supposed to improve your pedaling action and that is my excuse.

I've not ridden a fixed wheel bike since I was a teenager when a boy at school had one and I rode it a bit. However that was all before clipless pedals. I don't even recall if it had toe clips but I suspect not as I was considered a bit odd for having them.

I was expecting hills to be a problem having no gears going up, but in reality the problem is when going down where I've not managed to just relax my legs and let them spin or effectively use them to slow the bike without it all being a bit scary. Once I had got my self scared as my legs were whirling round it was not instinctive to use the brakes to slow the thing down. All very odd.

Traffic was less of a problem than I expected and I managed to get into the habit of slowing before junctions so I could just roll upto them. Since there is no freewheel you can't just lift the pedal to the top of the stroke to start again so you end up planning where you want to stop. It came as quite a suprise how far you move forward on a single pedal stroke.

The real surprised was how long the journey home took. I have no computer on the bike so I was only able to time myself approximately using my watch but it was 1 hour 10 minutes which was quite pleasing. I'm pondering whether a slightly larger gear might be a good idea.

Replacing Bike springs

It is almost five years since I replaced the original G springs on my right hand ergo lever. Over the summer I had noticed the shifting was deteriating so I proactively ordered a new pair of springs from Sigma Sport along with the new spring for my front brake. After taking apart the ergo lever the old springs were still intact unlike last time but were noticibly less springy than the new ones and so were replaced. It seems the life expectancy is five years or 20,000 miles.

Replaceing the spring in the front brake was quite simple. I was amazed to discover that there are small ball races for the barings on both the pivots however given the price of Campagnolo Record brakes I should not have been.

The bike is still not back on the road as a new chain has to be purchased and in these credit crunch times I'm holding off to see whether to get another record cassette or the cheaper chorus one. I don't think I will be getting any bling this time!

And what about the cyclist?

This neatly illustrates why I don't use bike lanes and why I don't think they will every work.
