metisse Posted August 3, 2017 Report Share Posted August 3, 2017 I have been asked by a French chum, who is building a Trifield, if I could find out the gear box ratios, and also the sprocket sizes that people in the UK use. Also once found, who could furnish such items. Appriciate any help as he hope to ride in Scotland next year, after struggling a little on his big Terrot. Merci.

Trifield is a twin motor in a Crusader frame so Cub detail not relevant Quote Link to comment Share on other sites More sharing options...
