2 new Continental gravel tires

Notices
Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

2 new Continental gravel tires

https://www.bicycleretailer.com/new-...d#.XWZsF1NOnqs

One for more faster riding and one for more adventure off the beaten path riding.
Both have a relatively tight center tread, but it looks like the trail model has more prominent shoulder lugs.

Both are pretty good for weight(in 700x40), are tubeless, and use the black chili tech.

Nice to see Conti finally getting in the game. Hard to keep up with Schwalbe though. Both are top notch.
I've been running the GP5000 as a slick gravel tire (although its not a very tough tire), and the G-One for something a little bigger with a little tread.

Those Conti's don't work well on rims that are at all oversized or hookless rims. They do talk about having an "official" road tubless standard within a year, and that would be a good thing. Those gravel tires meet the presumed standard (even if some of my wheels don't).

Terra Speed looks awesome. I wonder how it rolls compared to Maxxis Ramblers

My Ramblers are pretty light, but if Conte does anything like they do with the gp5000, I would expect these tires to roll very very well. Schwalbe tires have an amazing combination of weight and Speed too.

They are going to be much much harder to mount than the Ramblers are.

Has anyone tried the Conti Terras yet? I’m pretty happy with my 700c Gravelking SK 43s, but always willing to try out other options. Thinking about the 40mm Terra Speed or Trail tires, as well as the Vittoria Terreno Dry 40s, which seem to run bigger. Looking to retain the volume and speed of the SKs, but maybe add some better grip on my sometimes loose NorCal fire roads.

Looking forward to the reviews on the Terra Speed on how it performs compared to the G-One's. It's 240+180 tpi is the highest I can recall for a gravel tire.

"240 + 180" in Continental Speak means that it uses a 60TPI ply. 4 plies under the tread is "240", 3 plies under the sidewall is "180."

Marketing people play stupid numbers games with TPI. High-TPI fabrics are usually thin and flexible because more TPI usually goes alongside thinner threads. But it doesn't have to.
If a company were to take the threads that they use for a standard 30TPI nylon fabric, and they weaved it into a 300TPI fabric, the result would be a very thick and stiff fabric.
Similarly: I haven't counted it myself, but according to Jan Heine, Rene Herse "Extralight" tires actually have a lower TPI than Rene Herse "Standard" tires. The fabric for the "Extralight" casing is purported to use the same threads as the fabric for the "Standard" casing, but in a sparser weave.

Not that I want to be too harsh on Continental. They're not very secretive about the silly addition tricks they're playing to claim high TPI numbers, and their competition is forcing the issue.

Yeah, what he said. You have to divide conti's numbers by 3. so 240 = 80 tpi.
Its an easy mistake. 300 is a high thread count usually only done by hand made cotton tires. Conti says they have 330 on their road tires. I got all excited until I realized its really 110tpi.

That said, low TPI makes a tire that is harder to tear and easier to puncture (well, in theory) - which is good for tubeless. They will self heal punctures, but a gash will take you off the road. So where they make tubed and tubeless tires they make the tubed tires 110 TPI, and the tubless 60 TPI. Makes sense from that perspective. They both feel pretty supple to me, but I can see the thicker threads in the 60tpi tire (vs 110TPI).

Just be warned. Conti's road tubless tires are a pain to put on unless you have a properly matched rim (not a hookless rim). Super tight, super thick bead.

@HTupolev Thanks that is good information. How about Schwalbe's 127 tpi rating on the G-One (Schwalbe says 'epi')?

@chas58 Thanks for that info regarding Conti. I already got burned with this on Vittoria tires which had on the sidewall, not to mount on hookless rims.

You have to divide it by however many plies there are. This tire doesn't use an 80TPI fabric under the tread and a 60TPI fabric in the sidewalls, it uses a layup where there are 4 plies under the tread and 3 plies on the sidewalls.

I believe that Schwalbe lists the threads in a single ply.

I think his point is that the diameter is pretty tiny, causing the bike to lower significant compared to a 700c equivalent. Most people run at least 650bx42 or more commonly 47-48mm

Good point. Makes sense in that Conti typically does 60tpi or 110tpi thread count. 60x4=240.

I'm running my 32mm conti road tubeless on hookless rims (in spite of the warning). Running hookless I can't get near the maximum tire rating of ~100psi. I'm happy at 60psi (which is below the rim rating). I will say that they were a nightmare to get on the rims - possibly because they are hookless. Conti Road tubeless has very precise tolerances. Presumably this will be an ETRO standard soon...
