Will a  18x2.5 36 hole rim (excel) mount up using the stock tenere spokes or do I need different spokes too? Not looking to buy a complete wheel or wheelset, just want to change rim. I see off-the-road.de sells the rim and spokes but they don't have any details on #pn . TIA 

I ordered the rim and spokes from off-the-road I'll post part numbers if they are available once I receive the wheel. Hopefully someone in North America will be offering rim options soon.

Thanks for this. I heard Warp9 has complete wheels coming for the T7, I'm waiting for prices before deciding on rim and spoke or complete wheel.

So sort of bad news on the rear rim. Its not an off the shelf wheel. It was a blank 36 hole excel wheel that's custom drilled.  No part numbers for the spokes so all I can do there is measure them.
