Yup....he will drop you going down the hills, especially ones that take you out of your max cadence range...but on flats you'll hang on him like glue with 3/4 of the effort. Going up hills (depending on how strong you are and your gear inches) you'll drop him again.

If you ride with roadies drop your gear inches back about 5". So if you run a 16 tooth cog in back normally buymp it up to a 17 tooth one and you'll notice how much more fun you are having staying with them.
