Anyone happen to know what size the rear axel is? a friend is looking to swap over the wheel on his blackbird to an sp2 wheel but doesnt know if it will fit. I'm too lazy to take the axle out of my RC so figured id ask someone on here who might already have the axle out of their bike!

Looking for length and diameter please.

Cheers!

It's diameter is 25mm that's for sure.

As far as it's lehgth, I guess you need the distance between right under it's head on the left size up to where the bolt's threads starts.

Breaking that down means the thickness of (from left to right)

1) swingarm
+
2) wheel spacer L
+
3) Bearing
+
4) Wheel inner spacer
+
5) Bearing
+
6) wheel spacer
+
7) Caliper mount
+
8) Swingarm
+
9) 2-3mm freeplay

Right?

What diameter is the Blackbird's rear axle?

Not the best measurements...but my toolbox is lacking.

Overall length was 14in or 355.6mm.

That would be 325mm to where the axle tapers down to the thread area, which is 22mm diameter.
The tapered area is 5mm wide, and the thread area is 20mm wide.
