Changing Front Sprocket on the Fly: F800GS
Here is my plan:
change front sprocket to 17T and back to 41T for commuting/touring/getting to the trailhead. When I get to place where I will go off-road for a bit, change the front to 15T. Sounds like it can be done in 30 minutes or so.
Sounds good in theory, best of both worlds on one bike (Good top speed for the open highway, good low end for the back roads). But how about in practice? Do I have to change the size of the chain or just adjust it after I change the sprocket?
Am I missing something?
