I have used them on hookless for thousands of k. They have issues, but staying on the hookless rim is not one of them.

Can be ordered directly from Specialized.

Alright, so ride reports coming up soon. I'll have to run studded tires for few more weeks, so no need to do decision before reviews.FlatlandClimber wrote: ↑Wed Mar 02, 2022 2:33 pmMine are due to arrive tomorrow.

So they just put less tread on it for a lower starting weight?yinzerniner wrote: ↑Tue Mar 01, 2022 6:09 pmInteresting development from the big S. 435g per 42mm tire is quite nice, especially if they can roll faster and feel better than the already fast Pro model

All else equal, less rubber is a shortcut to lower weight and rolling resistance (...and puncture resistance and durability, but...)ricerocket wrote: ↑Wed Mar 02, 2022 8:23 pmSo they just put less tread on it for a lower starting weight?yinzerniner wrote: ↑Tue Mar 01, 2022 6:09 pmInteresting development from the big S. 435g per 42mm tire is quite nice, especially if they can roll faster and feel better than the already fast Pro model

According to that link and others they also changed the casing design. Less and different rubber compound config, different casing, lighter/faster/more supple tire supposedly. But most likely will lead to less puncture resistance.Singular wrote: ↑Wed Mar 02, 2022 8:40 pmAll else equal, less rubber is a shortcut to lower weight and rolling resistance (...and puncture resistance and durability, but...)ricerocket wrote: ↑Wed Mar 02, 2022 8:23 pmSo they just put less tread on it for a lower starting weight?yinzerniner wrote: ↑Tue Mar 01, 2022 6:09 pmInteresting development from the big S. 435g per 42mm tire is quite nice, especially if they can roll faster and feel better than the already fast Pro model

Correct, there is quite a bit of difference - that's the reason for the "all else equal" first. In this case they've done a bit more, but simply opting for less rubber has the mentioned effects.yinzerniner wrote: ↑Wed Mar 02, 2022 9:03 pmAccording to that link and others they also changed the casing design.

Just switched from 38c Gravelking SS to 40c Conti Terra Speed TR. I have to say the Terra Speeds really do seem to roll much better, especially on the road. Just a few grams weight penalty with terra speeds. On the gravel, I cannot tell a difference between the tires when it comes to grip, comfort, and overall handling. BUT on the tarmac sections of my local routes and races can be for miles at a time. The gravelking SS always felt soft and mushy on the tarmac. Very muted with no feedback. With the terra speeds, they just feel like I'm running a road tire, even at lower pressures. They hum along nicely at speed. Also out of the saddle climbing the TS's don't feel as squishy. Maybe it's all in my head. I did run the Gravelking SS for a couple of seasons now so I am quite familiar with them.

This is exactly my experience, the TS roll very well on pavement, not as quite fast as pure road tires but fast enough to do just fine on extended sections of pavement. And it makes sense, given that performance on smooth pavement is what drum tests best predict. Once you get offroad it gets more complicated and tire width, tread, and compound become important factors.nickf wrote: ↑Tue Mar 08, 2022 3:26 pmJust switched from 38c Gravelking SS to 40c Conti Terra Speed TR.

so looking for a new tire.
currently running gravel king SS 38 mm
in the run is:
s-works pathfinder
conti Terra speed 40mm
challenge strada biance pro 40mm
challenge getaway pro 40mm
Currently leaning toward the strade 40mm but weight seems high (stated at 460g) same as getaway, so might go for a little more grip.
Getaway seems to have the best punture protection and grip off them all. with a low rolling resistance.
would that be the best tires even though i dont feel like needing more grip from my GK SS 38mm

I just grabbed the 48mm version of these Soma Vitesse. Hoping it's decent. Made by panaracer too like RH. 380gm for 42c.

I prefer 40c Terra speed which were about 460gm to 38c pathfinder pro 480gm, but didn't enjoy cornering in damp. Will report back on s works Pathfinder once they arrive too.

There is also the Gravel Grinder which seems to be a GK SS style of tire, in the spectrum between the Strada Biance and Getaway. However according to BRR this has a much higher rolling resistance on smooth surface compared to the two you mentioned. It was tested in 2020 so maybe there was an older version. Looking at the tread it is not intuitive for it to have more resistance than the Getaway.mathias720 wrote: ↑Wed Mar 09, 2022 12:48 pmso looking for a new tire.

Just a note on the Terra Speed: it does roll well. But, that is about it in my opinion. The grip is very mild on anything other than well groomed gravel tracks. I had set them up tubeless and after a few weeks the air was going through the whole of the casing. Also, the tiny knobs on the rear dont last long.
