On the wheels front, I have H Plus Son Archteypes built with CX Rays on Bitex hubs which are very good, and were a good price here: Leadout Cycles. On my other road bike I have Velocity A23s built with Sapim Race spokes on Hope Pro 3s, which if anything are better – bought from nixon_fiend on here for a very good price (thanks again, by the way!). Also available for not much cash and very nice wheels.
On the hookless thing above, Continental GP4000S and 4 Seasons both specifically state on the sidewalls not to be used with hookless rims. I would be nervous, personally…
