Racing 5 LG with 23c GP4000s are £180 on Merlin. I trashed an old hub on Monday evening, ordered these Tuesday and arrived Wednesday, tyres on. Can't fault that service.
The 23s on these, are about the same width as 25c 4 Seasons on the 13mm internal of my old wheels.
Only thing I doubt is the number of spokes- 18/20.
