No, just a group of people out riding.
I did see someone on a Cube, that fell of it whilst being stationary!
Here is another group that I really impressed me. They were out on a club ride, with the lead rider going at a sensible pace for the group, and a tail end rider that kept pace with the slowest rider, never leaving them behind. The group also waited patiently periodically for the slowest to catch up, and also gave them breathing time. The club runs three rides a week, with three different abilities, and also much more beside including a bike shop discount card. All that for a fiver a year.
Georgehenry, I'm currently thinking that I might put a single chain ring on my Ultra 1964. I have been riding a few other bikes lately that have a single chain ring set up, and prefer it.
