Hallo all,

I bought a set of Storck Powerarms for Shimano blades and square axle. I suppose this is a JIS axle but it does not say anywere on the box.

So now I am wondering: what's the lightest available JIS axle for a triple? I need an axle for a triple to use it with Spooky chainguards in a monoblade setup (normal axle would be to short to keep the inner guard free from the rear fork).

For example: are Tune square axles JIS or ISO?

I would look into Action Tec spindles. They are pretty light and offer a wide range of widths.
