Can anyone crunch the engine performance calculations and figure out if these gear ratios will work. I'm at loss. peace

Its early sat max be patient, theres some guys here who can rattle that stuff off just in their heads. After the fri night partying theyll arise about noon out of their caskets.

Max,

This is how you need to input the info for the engine calcs. Your current set-up will be geared too tall!

The pedal side is right.

ok how about these numbers. I changed the 16t sprocket to a 13 t sprocket. I plan to order from staton-inc (see screen shoot) and he only has the 16t-22t sprockets for sale with his freewheel adaptor. I'll have to order the 13t special. I can also get a 14t-34t cassette if necessary too. anyone know of bigger cassettes? I've also attached a picture of my plan for this jackshaft. Its a little convoluted. I need to find someone here in sierra vista to machine out the threads on the bottom bracket adapter so the bearings i have will fit inside. I tried to press the bearings in once and completely screwed the adapter up.
