    Posted: 26 September 2016 at 10:36pm
I've bought a 2011 Ice Adventure, my wife has a Dahon C5 Ciao, I'd like her to try the trike as for sure as eggs are eggs she will come a cropper on the Dahon (she's 75 & old bones don't bend). She is 6 inches shorter than me so I thought a chain length compensator would enable her to try it & maybe persuade her to get a trike. The kit from Ice is very expensive, I did read the description of a home made where they had used a skate board wheel on a sprung bracket as a compensator. Has anyone done similar or any other ideas, possibly a fixed derailleur to use when the boom is retracted to take up the chain slack?

The simplest & least expensive solution to this where there are only 2 different sized riders is to have a removable section of chain & a couple of quick links, bit messy but it won't be for ever.Big smile

I have seen a homemade one somewhere, and been racking my brain trying to think where.

From memory it was 2 jockey wheels sandwiched between two aluminium plates with the plates centrally mounted on a frame, it was sprung loaded.  The chain went in a "z" around the jockey wheels with the whole assembly tilting when more chain was required.

Difficult to describe but easy to fathom once seen.

Cheers

Ian

Thanks Ian
I've decided on the removable length of chain idea as there will be only me & my wife using the trike.
