Title: EV tubeless rear wheel on CalVin?
Post by: wguntz on June 24, 2020, 03:24:09 PM

Greetings to the group!  I am hoping to replace the steel tubed wheels on my '09 California Vintage with tubeless Alloy Borannis from a '98 EV1100.  The front wheel was not a problem once the spacers were modified a bit.  The rear Boranni has the same hub width, and it fit on the rear axle using stock spacers.  Brake rotor lined up and everything!  Then I looked at the rear drive, and saw that there is a large (1 cm or so) gap between the outer edge of the rear drive and the outer edge of the Boranni hub.  Turns out the oem steel wheel has a extension around its edge which fills this gap in the stock configuation; the EV tubeless Boranni lacks the extra flange.   I don't see any direct mechanical problems with having this gap, but I does seem like it would expose the hub splines, etc to the elements and is not very pretty.

Has anyone solved this problem?  Any ideas would be much appreciated.

Thanks and Ride Safe!
Wayne

First off, Welcome to the forum!
Note that I really don't know anything about these newer models, but I do know that in the past, different flanges (red arrow in the picture) were installed in the rear drive. Because of this, fitting a cali 1100 drive on a T3 with it's original wheel left a gap between the hub and rear drive. Swapping the flanges over solved it. Is your rear wheel still in line with the bike?

If that's not the case, relacing the old hub on the new rims might be possible. This depends on the angles the spokes make.

It's almost blasphemy!  Those Vintage wire wheels are moving artwork.  If it was me I'd stick with what I have, and just admire them.

I believe that the drive housing itself is narrower and the setup requires the housing from an EV or Bassa to eliminate the gap

I have done a bunch of this. Steel wheel hub on the rear drive ring gear is longer. This requires you put a shorter one in the rear drive, check shimming and assemble.  #28 in rear drive parts for Cal Vintage.

You need PN# GU17351400     instead of PN# GU03351450

EV tubeless wheels are one of the two best upgrades you can do to your CalVin. Steve gave you the answer and he would most definitely have the correct one.

The other best upgrade is to replace the windshield if the buffeting is bad for you.

I'm getting ready to swap to tuneless spoke wheels on my Jackal.  Anything I should know besides the obvious?

I looked into this a while ago.  The part you need is $400+ from a dealer.  I ended up buying an EV rear drive complete for not much more than that.  I figure I’ll sell the other and recoup my costs.
