Ah, i was wondering what kind of big ass tyres you were running. 38C slick? Nice! Never seen that before. The new Long Teng 301 can clear 38C as well, so it means these could fit.
Please let us know after you've ridden them how that feels.
I love my 30-32C combo on wide rims (from Xmcarbonspeed in fact), but given how wide they get, i'm thinking of going 28&30 tubeless next time (in GP5000 still), because that would still be super wide. To respect more the 105 rule.
38 slicks is next level after the next level, idk what to expect!
My first choice was actually going to be Conti GP5000 AS in 35c but they were out of stock at Merlin-Bicycle Rolling Resistance website had some comments on the Schwalbes that they were undersized for a 38c.
So my handle refers to being a bike messenger in Northern Germany in the 90s and we were huge into maintaining momentum (and speed) over poorly paved roads and cobblestones. Best tire choices were usually tubed wide slicks/semi-slicks on 26" wheels but as was the practice at the time, on typically 17-19 at most IW rims at the max pressure on the tire sidewalls to prevent pinch flats. I once managed a deep two wheel drift without crashing on a pair of 26x1.75 Michelin Wildgripper Rock tires where I was completely puzzled as to why I didn't crash hard-this is the kind of moment I'm looking to relive with far better equipment.
ETA: Was also considering the Challenge Strada Bianca in 45c, but there were a lot of comments about them unpredictably loosing grip in dry sand/gravel over pavement conditions.
