F4i vs F4 forks

Hi there,

Question: Are F4i forks different from F4 ones? Will they fit as F4i ones?

I kind a need new ones for my 9ner.

Thx

Thanks! Answers a question I was soon to ask.

Also, do you know if the fork tubes from the 919 will fit the f4 outers and internals? It seems like there's a lot on e-bay with slightly bent tubes. Might be a way to save a couple bucks.

slightly bent tubes could also mean a knock on the fork leg which will lead to the tube having small interference, which leads to more money rather than less.
Just a thought

No, outers/internals are different and will not mate up.

Also, NEVER buy bent tubes unless you have the means to accurately measure the internal parts to ensure they're not bent. That can be some pretty expensive tools for some people.

Ah, oh well. Thanks for your help. Do you think a decent set of V blocks and a dial indicator would be good enough to check for straightness? I make no claims to be a machinist.

With the right tools, anything is possible! Best person to discuss this with would be LDH and Rob Tharlson.

its not just straightness a small knock could deform the inside of the leg, it might not be visible on the outside , but when you slide the tube in it will jamb or not slide smooth.
If they are cheap enough or you like a gamble go for it.
it is just something to think about

Thanks Dave. Chances are I'll just try and find a leaky straight set on the cheap and go from there. I at least know for sure then that I can make them work.

Sorry for the hijack arendaja!

No worries.

Guy selling those forks doesnt know which one is which and he has 2 different set. Any hints how to recognize the F4 ones?

This kind a picture was sent only.

f4/f4i are exactly the same. However, my advice is to not buy tubes without the lowers. The lowers were removed for a reason and you cannot test the components without the lowers on (that I'm aware of).
