adjusting the chain wheel

Greenspeed GT3
chain wheel

On the bents and folders ride, I got a sore knee. One of the other bent riders, who I road back along the Cooks River Cycleway with, suggested that my pedals were too far away. So I thought I should adjust them. When I rode to work this morning, my knee hurt again, not at the start, but part way along, so it was really too late to turn back. So I left a message on the DHBC board asking their advice, as there are many expert rides and those with lots of experience, and some with both, in the group. I got several very helpful bits of advice, that agreed with this theory. So I decided to adjust the trike. While I was doing so, I dug out the greenspeed manual to work out how to adjust the chain. It also contained info on how to adjust the position of the chain wheel, so I followed their advice. I have moved the chain wheel back by over a centimetre to the greenspeed recommended position and removed 8 links from the chain, that was too long to start with. So I will see how I go in the next few days.

Sit on the seat and place your heels on the pedals and adjust the extension so that your leg is straight when in the outstretched position

  1. The change in sitting position is very great, but I had greater power up hills and my knee did not hurt this morning.
