I recently picked up a children's bike from a council waste site. I'm going to refit it and I had a question about the compatibility of the gear shifter and chainset.
The shifter is a grip-shifter made by Saiguan (it looks very similar to the SRAM shifter). The left hand shifter has three settings and there are three rings on the chainset.
The chainset needs replacing but the gear shifters look like they are ok. However I can't locate a 3-ring chainset which has a crank-arm short enough for my child. Therefore I was going to replace with a 2-ring chainset.
So my question is are there any 2-ring chainsets compatible with a 3-gear shifter?
Hope this isn't a daft question, and thanks in advance for your input.
