EBR Front Wheel Swap to XB

[SEXT9]

As I already posted to my build thread I purchased a new EBR front wheel and planning to install it on my 2010 XB12SCG. This has been done before. But I couldn't really find any specifics on the conversion. So, here I'll chronicle the adventure.

So here's a picture of the new EBR wheel.



The bearings on the EBR front wheel have a 30mm inner diameter while the XB bearings are 25mm. So we're definitely going to need some custom spacers.

It's worth noting the XB's rear wheel bearing has a 30mm inner diameter while the S1, X1 Lightning rear wheel bearings have a 25mm inner diameter. There are currently conversion kits on ebay that allow the XB rear wheel swap to the S1,X1 Lightning.



So I purchased a set for 35.00 and will try and modify them to fit this application.

I grabbed the caliper and took some measurements before I go modifying it.


Here's the thinner adapter.

Here's the thicker adapter.

Here's some measurements on the wheels


XB Hub Width



EBR Hub Width

I also measured 133.76mm between the forks.

 

[SEXT9]

In order to setup the spacer on the rotor side, I laid a ruler across the hub and measured from the ruler to the rotor on the old rim. That measurement came to 17mm.

I installed the rotor on the new rim and did the same measurement which came to 15.72mm

So that tells me the spacer needs come past the hub face by 1.28mm. The inner race to the hub face measured 5.2mm. So I'll have the thicker adapter shaved down to 6.5mm.


Both adapters will get the overall diameter shaved down to 36mm to fit within the bearing seal. Once the work is done, I'll post up the new measurements.

Great work man. Really. Thanks for the deets and I can't wait to see it all together!

Do you have a lathe? This will be cool when its done.

Very interested in this

Not knocking your thread as I am enjoying it also, but I think Ross already did this.

I know. I saw that thread. It was an inspiration for me to do it. However, as I began with in the beginning post, this has already been done before. I just didn't see any specifics for anyone else to do it as well. Thats why I'm running this thread.

Today I got the tire mounted to the rim. I also had the local machine shop mill down the adapters. I asked for the overall diameter to be reduced to 36mm on both pieces.



Here's the thinner of the 2 parts. Only the overall diameter was changed to 36mm.

Here's the thicker of the 2 adapters.



The overall diameter was changed to 36mm same as the other one. And the thickness of the shoulder was reduced to 6.5mm.

 

[SEXT9]

They installed in the wheel with no problem.



They are close but not touching the bearing seal



I installed everything on the bike and torqued the axle down. It all moves freely.

That is fantastic, thank you for taking the time to add the technical details about my favorite bike on here:love_heart:

They are close but not touching the bearing seal

Do you mean the 36mm OD of the spacers is not quite sealing and should be a slightly bigger diameter? Or the face of the seal clears the adaptor like it should?

And by changing the overall thickness of just one side of the adaptors, does the rotor still travel in the very center of the caliper? The opposing pistons would automatically compensate for a little, but the pads would wear un-equally.

I'm asking because I have an extra EBR wheel:applause: Where do I send the royalties check??

 

[SEXT9]

By not touching the seal, I meant they clear like they should.

They do clear the caliper as well. When moving the bike around, there's no scrubbing sound of the caliper.

I haven't ridden the bike lately. My girl has been with me lately and she prefers the Harley. Then I bought a new Tesla so I've been getting to know it.

Thanks for the answer:up:
I wonder why

had to notch the fork lower about .050" in one spot to clear the wheel hub,

and you didn't? Sounds like one of you guys has the front wheel offset a tiny bit.

 

[SEXT9]

I dont know what phelans measurements were. Otherwise I would have used them. I based mine off how the front brake rotor sat on the original XB rim.

And THANKS for the specifics, I'm calling my machinist today Dang I wish I had a lathe...
