I own a standard giant 26-speed road bike. Its a recent purchase and still in near perfect condition. Needless to say i hope to keep it that way. Also, sorry in advance if i use the wrong terms or have a false understanding of some things, i'm new. Im a high gear biker, i tend to keep my bike shifted in either 3-5 to 3-8 on staight aways and 3-4 to 3-2 for climbing. My father recently informed me that these habits could wear out my high gears while the others would be fine. A terrible reason to have to buy a new cassette. Anyway my question is; does anyone know what the rough equivalent of 3-5 would be with the front gear set to 2 on a 26 speed?
