    So you want to take a 10 speed out and put an 18sp in?? You will have to shorten the driveline, and maybe change the flywheel or clutch depending on the input shaft of the 18sp. But the only thing that will change drive ability wise is you will be able to split gears. Top end speed wont change and it will seem to pull the hills better because of the splits but thats it.
