Yeah they have quite a few variants though I'm not sure its clear to customers.
Just looking on a distributor's website there's 120tpi and 300tpi versions of both tubeless and non tubeless. The 300tpi ones are handmade
There's also tubular.And they come in black, white, tan, brown

Mine were 300tpi (why pay less when you can pay more?), if that helps.

Haven’t used tubeless but used both PR and SB pro series tyres and the PR race vulcanised tyres.
Pro series tyres are utter arses to fit on tubeless compatible rims but lovely rolling and good compound. Grip predicable and good in both wet and dry. Both have double puncture strip in them (updated as originally PR only had single) which works fairly well, I ran SB all winter with 1 puncture which is pretty good for Devon lanes. On 21mm internal rims the PR came up about 30mm and the SB about 33mm.
Pro series uses a super poly casing rather than cotton (300 vs 260 tpi for PR vs SB). The white version uses a silk casing which might rot if it gets really wet and is left wet.

Are the Roubaix tubeless? I’ve used the 27mm, I thought non-tubeless but maybe there are two variants, and had no complaints.
Some reports complained they were easy to puncture, but that could’ve been the older model.
