I have some questions that I don't seem to be able to find the answers to. I've only been riding for a month or so and I'm trying to learn all that I can.
1) What kind of performance difference (if any) will I see by switching my cassette for an upgraded one?
2) How much of an upgrade would I need to see a difference if any? I have a sram pg-950 9spd now. Would a Shimano Xt cassette even be considered an upgrade or would I have to go even higher to see any benefit?
I have sram x7 trigger shifters and rear derailleur if that makes a difference.
3)I noticed yesterday that my large cog on the front is SLIGHTLY bent. Looking down on the chain, I can see a slight wobble to it when turning the pedals. Big deal? Don't worry about it? Change it asap?
4) My rims are wtb speed disc. It's spec's are 559x17 541 ERD. What do these numbers mean?
5) I have 2.14 49/52 wtb motoraptor tires. Would it be to my advantage to go to a wider tire? If so how wide could I go and what would the positive vs negatives be?
Most of my riding is xc. Nothing extreme at all. Logs and stuff but no actual jumping or drops.
I appreciate anyone taking the time to answer these questions or referring me to a link that answers them.
