For the last couple of weeks I've thought I had a problem with the Typhoon. It seemed noisier and didn't pull as well. Then I noticed I had a couple of broken spokes and a buckle in the rear wheel. Down to the local bike chappy and £12 later, the spokes are fixed, the wheel is straight and the front brake is all adjusted nicely.

I took it out for a trial spin this morning and normal service has been resumed. The service was so normal that it was sunny when I set out and I got soaked on the way back. The bike is now pulling well and isn't noisey.

I had a problem a couple of weeks ago and imagined all sorts of catastrophic possibilities . All worries were unfounded as it was simply a loose pivot bolt.
