I'm looking at getting a decent mountain bike that will probably spend quite a bit of time on the road.
I found that the most common types of chainsetsare either:
- Shimano Altus 2x9
- Shimano Deore 1x10 (on the more expensive models).
- SRAM SX Eagle 1x12 (on the much more expensive models).
When I compared the ratios of these three chainsets, the Shimano Altus seems to have lower low end speeds and higher high end speeds, so in general it seems like the better option to me. Yet I can't understand why the 1x Deore and 1x SX Eagle are the more expensive options, aside from the weight loss, is there any other benefit to them or is this really just a case that the Altus is better? At least in terms of speed (which is what I am mainly interested in).
Am I missing any other important comparisons? Aside from weight and I guess it being easier to switch gears in a 1x setup (i.e. chain not crossing and stuff).
