Thanks again guys I'm going to go with the derailleur setup if this hub breaks. I'll go easy on it. Can I get some help with rpm and speed I can give all the info. 10 tooth engine, 17 tooth jackshaft; 11 jackshaft, 44 tooth chain ring; 36 chain ring, 18 tooth on hub. Ratios for hub are 1st 2.8, 2nd 3.4, 3rd 4.5, 4th 6, 5th 7.2. Sorry I'm posting from my phone my laptop is busted and I can't use the ratio program.
