Fox Campus Trail Bike Build

Alternative- to increase your gear ratio (make the bike lower geared) you can increase the number of teeth (diameter) of your jack shaft "input" sprocket. That is the sprocket connected to the clutch. Or, you can decrease the jack shaft out put sprocket- the sprocket driving your rear wheel. From the photos, it looks like your output sprocket is pretty small.'

Both of those actions require chain adjustment, and quite possibly adding or subtracting chain links. If you have that tool, it is a very easy job to do. I would rather do all of that, then pull the rear wheel off and deal with changing the rear sprocket, if I were a guy just starting out with these. (simplicity)

One tooth can make a big difference. Glad to see you got it up and running.

Thanks for the input. The output sprocket on my jackshaft has 14 teeth. The hope is to eventually forgo the clutch and attach a cvt in its place. The more I dig into it I'll find out if that will work how I'm expecting. Would like larger diameter tires to allow for more ground clearance. That was a big limiting factor on the camping trip. Always open to suggestions to improve the bike.

Got the base rough cut today. Still need to round the edges and drill the holes for the T-nuts. Then just paint to seal it and off to the upholstery stop. 20181209_134817.jpg 20181209_134839.jpg 20181209_134805.jpg
