Kinlins are available in silver
Here's one that appears to be in stock
https://thecycleclinic.co.uk/collections/rims/products/kinlin-xr22t-rt-rims-in-silver-700c
Also there's a Pacenti Brevet and "Pacenti Forza Classico" are listed as tubeless ready on Cycle Clinic but both out of stock
These are ideal - just hope the hubs are 32h not 36!
