a custom or non-standard style cassette. My current cassette is this... Model: Shimano CS-HG50-10 Size: 11-36 Cassette Cogs: 11-13-15-17-19-21-24-28-32-36 I don't find the smaller cogs that useful, esp 11 and 13. I find the larger cogs more useful for climbing and cycling in general. Does anyone know where I can find a 10 speed cassette that has a cog starting with 14 or 15 teeth all the way up to a cog that has 38 or 40 teeth? The climbing gears would be much more of a benefit to me. Thanks!
