In the last year there really has been no time for riding or for working on bikes. So apologies that everything has been very quiet. Having said that being back on the bike has shaken a few things loose. The first bolt to er.... bolt was a crank bolt on "I should Coco". I finished the section holding the crank on by force of will and foot. Now call me stupid, but I would have thought that with a simple machine like a bicycle the range of methods for attaching the crank arms to the bottom bracket were pretty standard. So stopping in Peaslake, I popped into the bike shop for a replacement bolt. Howard he say "No" - apparently no high tech enough for the bikes he sells. Fair enough.
One of the beauties of the internet is its accessibility and the range of information available - this time it fails miserably. My nearest bike shop is miles away (to the extent where I think opening one up would be a good business move, if I was incilined that way). Eventually, I make a trip in the right direction and pop in with the other bolt. It takes 10 mins of rooting in the spares draw, but eventually they find one that matches (visually) to what I need. I still have no idea what size, configuation the bolt is.
A familiar story on the internet - but here just a bewildering array of choices. A trip to a bike shop that deals in high end gear is unproductive in walking out with desired product, but helpful in learning about variations in chainring bolts and lengths. I am able to order parts and replace.
