I have a Staton crank-shift kit up and running on a 21- speed MB. kit runs good but I need lower gearing and am not sure what the best approach would be. It came with a 12-tooth sprocket for the drive shaft, I changed that too a 10- tooth which helped a little, but not much. Now, I am not sure if a cassette change would do it or if a front crank set would be the way to go, seems a bit pricey really. In the advert for the kit he claims this will "go up any hill" , so I thought the lower gears ( largest front sprocket,smallest rear ) would be "granny low like ) but not even close. Any help appreciated..........
The stock cassette is 7-speed, 14- 28 tooth
