Which front fork brake mount is better - Post or IS?

Postby tbikeradar » Mon Oct 01, 2012 14:14 pm

Hi everyone.

I just wondered what your opinion is on brake mounting standards.
Which front fork brake mount is better - Post or IS?

My reason for asking is that I may buy a 2008 Fox Talas front fork with IS mounts.
My brakes will fit with the correct IS or post adaptors, but it seems that all the new forks are post mount.

What are your experiences with the different mounts, any pros / cons...?

Thanks for your advice.

post: con threads in an expensive bit of metal.

IS: maybe a fraction heavier.

Thanks for the advice, much appreciated.
I did wonder if post was more stable and robust due to the torque stresses from braking.

Clearly busting the threads on a post mount is not good.
Thank goodness for adaptors!

IS, do Boxxers still come with IS mount?? Apparently frames seem to be going towards PM as standard, it's stupid IMO.

So what's the point of PM? I thought this was the new "better" standard?

Obviously you have never had to file a bit off a Fox fork Post Mount to get your disc bolts to clear the fork

No I haven't.

Clearance because you have two individual poles, rather that the bracket which is joined across the middle to make the poles.

Yeah, but, what's that providing clearance for? That's what I'm getting at.
