MakisRC51 There's only one way to find out's called caliper vernier and an HD camera for the rest of use to see, buddy

The Stig Next time I take off one of our wheels, I can check the thickness of the caliper bracket... May be a while though, as it'll be months before we get it running at the rate we're going...

Then again, I need to fit my underslung sometime, so sooner than later would be a good idea since I have all the bits. Time is the thing I find myself shortest of, as there's always other stuff (unrelated to bikes - which are really & purely just a hobby) to do!

....Ah, I wonder if the SP2 underslung is the same thickness as the original? Should be - right - or would that be too much of an (easy) assumption?

MakisRC51 Measured the SP2 gap (the 267mm distance on the SP1's swingarm)
Guess's 268mm

So why the longer pivot?????

The only different part on the SP2, except the swingarm, is the caliper mounting bracket......perhaps it is thicker?

Could you measure Carlos' bracket for comparison if you get your hands on it sometime?

MakisRC51 Don't take it all on yourself buddy....if you'd asked me, I'd tell you the same so I would've been wrong too.

Please guys, any other measurements you need, now is the right time that everything is apart.

I still wonder though Miguel,......SP1 and SP2 swingarms are supposedly the same in width. They differ in least that what I thought, up until now!

The Stig Well, whadayaknow - they are different

Thanks for making that clear, buddy. I was wrong there.

MakisRC51 They have different part numbers

SP1: 42301-MCF-000
SP2: 42301-MCF-D30

....and what do you know....they are actually different (I'm a bit surprised)

SP1: 351mm
SP2: 355mm

The Stig The Spindles are the same part number for SP1 & SP2, I believe.

MakisRC51 Since I have to make the two front spacers fully customized sized for my fork settings, I'decided I'll have the rear made too.

I will go with 7075 aluminum alloy (same material as the Kyle Link) for both wheel pivots as well as the swingarm pivot.
That way there isn't the slightest possibility of fusing the pivot together with the collar due to corrosion, salty moisture or anything else.

And the 7075 is very strong alloy which makes it perfect for manufacturing pivots and axles. And it ain't that expensive either.

SP1 rear wheel's pivot measurements

Since I have on my bench, I did a couple of measurements to have them on my record.
I don't think they differ from the SP2 at all but I was measuring an SP1's parts.
