Is there any 8 speed rear mech that has a short cage? If not then can you change from a long cage to short cage?
You can use a 9 speed mech with an 8 speed shifter...

If you have an 8 speed drive train it's not worth it.

OMFG how did I miss this? I really don't think he should even own a bike. His lack of willingness to understand even the most basic principles of mechanics is unparalleled on pb, and his ineptitude at accepting and following advice he is given seems to be grating on all of us.
Does he even know what tires are filled with? (The same thing as his cranial cavity!)

@spicy Mike...

Dude how do you even keep a straight face when he asks these questions? Boy you must have some serious patience!!
he should try poker

Hahaha i dont. I do have tons of patience but that doesnt mean i dont go wtf.. I get we all started from somewhere so i can get that, but i dont think theres anyway anyone can look normal asking those kind of questions frequently without bothering too do your own part in learning/reading.

What you can do is get a 9sp short cage derailleur and hook it up to your 8sp shifter, you have to buy a matching derailleur to what brand your shifter is, and from your pic you'll need a Sram. However setting it up will require you to either take it to a shop or watch a few videos on youtube to figure it out.

However if you are just upgrading for the sake of upgrading, I would upgrade the shifter, derailleur cassette and chain all in one go, and I'd go 10sp while I'm at it.

Also, from your pic, you have front gears as well. You cannot use a short cage derailleur with 3 front gears, and it's very specific at what it can handle with 2 up front.

What is the difference or what is ICSG 05 and BB mount for chain guides? I take it BB is bottom bracket but what should I get?

X7, X9, X0.

I'm buying a new mech and shifter. Currently run X9, would I really notice a huge difference if I went either way?

I never really feel like I have time to appreciate how crisp my shifting is when i'm actually riding.

I'm going to start climbing more, will I notice it more then?

I'd stay x9 for the mech, but get a clutch derailleur if you don't have one already. For the shifter get whatever you want/can afford. I'm running an x7, which is fine. Some people like the bearing in the x9 shifter.

Thanks Arnoodles.

I'll have a look around for the best price on each. I'll probably go X9 since it hasn't given me any issues until I gave it a whack. Might even go Shimano, the value seems much better.

Last question:

I'll change the front to a N/W ring and top guide at the same time.

Is this secure enough for occasional downhill duties? I've heard good things.

It should be. I just finished a day at Whistler riding my AM bike with a NW ring, no guide, and no clutch. Didn't drop my chain at all.

Also, you'll get better shifting from a higher spec shifter paired with a lower spec mech vs the other way around. And I'd go with an X9 over a X7 mech.

So I put a small nick in my 2013 Fox 40 Kashima Stantion today, is there anything i can do to fix it? or should i not even bother to worry about it and keep riding?

if the nick is near the bottom of the stanchion close to the oil seal it will leak oil every time the scrach passes the seal.

if its at the top half of the stanchion it should be okay as your not always using that much travel so the scracth wont pass the seal often

if the scratch is right near the seal you can lower the fork so the scratch in the stanchion is below the seal.


either way I would get like 1000 grit wet sand paper and sand the scratch to remove any high spots that will damage your seal. dont sand much just a few swipes directly ontop the scratch.

good luck man, it sucks happened to my brand new fox 180 after 1 week Frown


also I found the nail polish method didnt work... for me the nail polish kept coming off, like it couldnt adhere to the stanchions.
