Wow, why on earth would anyone buy the Mavic?? Worst rolling resistance AND the worst puncture resistance? How do you even manage that?

I love my Terra Speeds and really can't see anything replacing them. Most likely gonna run them for DK (a fresh set of course), I'll bring my other wheelset with the Terra Trails just in case it's muddy, otherwise the Speeds should work well.

Well...consider that the GGs all listed there are of dramatically different constructions and widths, so really not that surprising at all that the ones with a thinner casing and constructed with a glued-on tread, and/or have less puncture belts or internal butyl layers, perform better ;-)



It measures the efficiency of the casing AND the tread (compound and texture)...which are the major components of evaluating rolling resistance.

Just to add some real world data to the opinions of those that have no first hand experience, I soon will finish off my third Bon Jon Pass rear tire run with tubes and I have not had a flat yet. I ride 40% gravel on average. Mostly older worn gravel and sand here and not much glass, but still no punctures and the ride is marvelous! I used to love the Challenge Strada Bianca until I tried Rene Herse... I do not ride them down to the threads though, maybe 1200 - 1500 miles before I replace a rear. If I were riding DK I'd ride something a lot more flat proof, but for most of what I do Rene Herse is my go too skin.

Hmmm

I love the 45mm WTB Riddlers but they are anything but fast. Comfy? Grippy? Amazing on singletrack? YES! But not fast.

lol well that's how they're advertised. I'm no speed demon myself ... "Named after WTB athlete Nathan Riddle, the Riddler tire delivers raw speed yet hangs on in the corners, remaining composed and unflappable - just like Nathan’s riding style"

Hmmm

Haha. Love it. Maybe the 37mm's. But to be honest. I love the float and width of the 45's that although they are slower than my other gravel tires (40m Maxxis Ramblers) I prefer the Riddlers every time. Really a fun tire.

lol yup. these are my 2.25"

Tour Int just did a test on their flat rig
https://www.tour-magazin.de/magazin/aktuelles_heft.html

They stole my money once, so I was comfortable posting their articles for a while. Now I feel we're even after continued solid content. So I won't.
They tested:
Cont Terra Speed, Terra Trail
Kendra Alluvium Pro Boost Pro
Pirelli Cinturato Gravel H, M
Schwalbe AllAround, Bite
Vittoria Zero, Dry
WTB Byway Venture

40c tires 30kmh w/ 90kg pair on flat rig over stone and tarmac 2 bar (30psi) , 3bar, and 4bar (60psi)

Key takeaways: g-One Allaround performed the same as the Cont Terra speed. WTB still roll like ****. 30psi makes 4w difference on the road here. 60psi top level gravel tire takes 23.3w on this rig, a 7bar top level road tires does about 18.4w

Apparently I can't read the article. How'd the 40c Terra Speed fare?

Looks like Schwalbe sent a 38c Gone AA. They measured height and width, interesting that all these are taller than wide. Must have been a traditional road rim.

Tied with the G-one all around on top. The Cont had slightly better grip and oddly the best puncture results.

The Bite did way better than the Terra Trail

To be fair there's nothing in your post that says the Conti and G-One were on top. But that's good to know and confirms my suspicion that the Terra Speed is the best tire on the market right now. I absolutely love mine.

jfranci3

saw that, rethought it, and edited it before you posted here. Sorry

shoota 

No worries. Appreciate you updating us.

I bought the issue. Thanks for pointing it out.

Interesting...the % difference measured between the Terra Speed and Terra Trail was identical to what I measured (Terra Speed ~76% of Terra Trail CRR), while they also found the Byway to be basically tied with the Terra Trail. Again, identical to what my rollers found :-)

The outlier in common tires on my list is the Vittoria Terreno Dry. While they show it slotting in between the Terra Speed and the Terra Trail, my testing showed it being slightly slower than the Terra Trail. Now then, I also tested that Terreno Dry nearly 2 years ago, so maybe Vittoria has made some running changes in the mean time? Dunno.

In any case, it's pretty clear that both Tour's test and small roller testing give similar results, at least in a rank order and percent difference aspect ;-)
