so i have been looking at all different types of cassetts for my downhill bike, and i came apon this..Sram PG 970 Road Cassette 9 Speed 2007 which if i buy would go on a mavic deemax rim and hub, do you guys think this cassette would work good...for some reason i herd that the road cassettes would be a little better than the mountain ones?..or any other ideas.

it also happens to have the different sizes..11-21..11-23...12-23..12-26......i happen to not kno what size to get for mine bike if i do happen to buy this cassette....any help would be nice!

If you don't know what you want, get a wider range. Road cassettes are typically lighter and the ratios are spaced closer together for fine-tuning your gear ratio on the road. I run a 6 gear hub with a 12-32 spacing. For downhill it's not such a big deal to me. I do a lot of coasting.
