Hi,
    i have been using the Continental Speed Ride 700c X 42mm (measures 39mm on 19mm rims ) tyres and Continental Cyclocross Speed 700c X 35mm for about 15 months almost every day.

They have the same tread pattern, diamond shaped files with single row of knobblies on the sides.

The Speed Ride, 430g and puncture protection
The Cyclocross Speed 350g and no puncture protection.
 
From now on i'll refer to the CCS as 35mm, and SR as 39mm 

Both folding bead.


SPEED.
35mm
 Fast acceleration and flies on tarmac 80+ psi,
30 - 50 psi very fast on hard pack, gravel.

39mm
As above, but being a little heavier, accelerates a little slower.

GRIP.
35mm
Brilliant on tarmac and wet slimy concrete paths at any psi.
Hard pack, gravel, very good grip.
Muddy tracks, ok around 30 to 35 psi for gentle riding.

39mm
As above but 10% - 20% better in all conditions.

COMFORT.
Lovely roll, very comfortable especially the 39mm.

PUNCTURE RESISTANCE.
35mm
its a light tire, i have ridden a couple a thousand miles with 2 punctures, maybe i just got lucky.

39mm
has PROtection. 1 Puncture in around 1000 miles.

WEAR
35mm and 39mm
reasonable wear speed, had worse.

PRICE
 both often between £13 and £20.
So top marks for value.

If i went on a long tour, i'd have no problem going with them, and keeping a couple as spares they are so light and so cheap.
These 2 tyres do seem to go under the radar. 
Do check them out, i love them.

A friend brought up the 35s the other day.  My response was to look for something else, as they looked to me like a cyclocross tyre.  In cyclocross the pit bike is never more than a lap away, so they do without any puncture protection and just get off and run when it happens.  I'm surprised you've not had more than 1 per 1,000 miles, but even that sounds a lot to me.  I have one per 5,000km, and beacuise I run tubeless tyres they seal more often than they don't, so only one in maybe 15,000km have me putting a tube in.  Depends on your priorities, I know.

The 42s look more interesting for our application, as they look a more durable tyre with some consideration to puncture protection.  I personally don't like side knobs but that's just preference.  Bigger shame is that they're not tubeless.

Has anyone ever trying riding the continental Speed 35 mm tubeless??  Is it a bad idea??  I was thinking of trying it  with my rims, Enve 4.5 AR , which are tubeless
designed.  What do you guys think??  Bad Idea??

Thanks for the help!

I have heard that they don't set up tubeless. Casings are too porous and won't hold the latex. But that was a few years back. Maybe they've improved them.

I don't mind the occasional puncture, takes me very little time to sort it out on the road, either i swap out the inner tube with a new one, or if there is a source of water near by to see where the hole is, i'll mend the puncture.
When i was a courier in the early 90's in London sometimes i'd get 3 punctures a day, so i got pretty quick at fixing them.

The knobblies on the sides are very small, they help in more muddy conditions when run around 30-35 psi.

The 42's are a perfect gravel tyre. Cheap as chips in the UK.
£13.00.

I have run the 42mm w/tubes on gravel roads, and I have to agree with everyone elses observations, they were really a good tire.

My wheels, are pacenti SL23
tires wt: ~425gm
performance notes:  Very fast rollers given the size, which mine mearsured out just over 40mm on the wider rims.  They were very compliant w/tubes, they soaked up amazingly bumps, potholes, and were great on rough bad roads here in Mid Mo.  Never a flat

I would categorize them as underdogs.

There are very few reviews on them.  They are actually cheap compared to others.  In measuring up, they are actually better in many ways but nobody uses them.  Group rides, everyone runs the hallowed MSOs and etc.

I didn't run them tubeless and wouldn't, because they are thin sidewalled and I doubt most would get them to stick

I do run the GravelGrinders 38mm tubeless, and swear, in comparison, I think the Conti w/tubes still ran/run faster overall.

I am prob going in on the 35mm soon and run them w/tubes

Just stay out of the briars&brambles. The casing of the 35mm Cyclocross Speed does not like thorns and it’s not a tire I would try to setup tubeless, but it’s pretty sweet otherwise.
Edit: cyclocross speed

Conti makes some great tires.  Even the cheaper ones roll great - typically reducing a bit in the pucture protection or weight.

I really wanted to get a set of these tires, but the thread count on the 43mm is incredibly low, and the 35mm version is much much more expensive.  

Instead I got a fast set of tubless tires.  

I have mounted up Conti Grand-prix 4 seasons tubless.  I used skinnystrippers to help ensure I didn't burp, have blow offs, or leakage.  Works well.  Yeah, tires like this take a while to set up and seal the side walls, but they have worked great for me.  Fast  and light.

Thanks for the review - good info on some good tires!

Chas i looked at the 32mm Conti Four seasons.

The only advantage they have over the Cyclocross speed is puncture protection.

They are almost as heavy, only 32mm vs 35mm and have road grip versus gravel grip,
and,
Almost 3 times the price. Conti cyclocross speeds £12.00 on sale in the UK.

I did think of getting the 32mm 4 seasons, but if you can stomach the risk of punctures,( i have had very few) then its an easy choice.

I really can't recommend the Conti cyclocross speeds enough.

From Schwalbe Tire N. America/tire construction:

“In principle, the more close-meshed a carcass is woven, the higher the quality of the tire. A dense carcass is important for low rolling resistance and good riding properties. At the same time, puncture protection increases, because carcasses with a high strand density are difficult to puncture.

However, this does not apply to the extremely fine 127 EPI carcasses, as each strand is sheer and quite vulnerable. The best compromise for low weight and resistance is around 67 EPI.

In most of our top tires we use a 67 EPI carcass. Weight and rolling resistance can be reduced even further by using a 127 EPI carcass. But at the same time, these tires are more vulnerable to damage. Therefore, we intentionally use the 127 EPI carcasses only for light competition tires, where weight is an important factor.”

They consider 67tpi good all-around and 127tpi super light. I often buy ~60tpi/rear and ~120tpi/front. 60tpi being cheaper and more durable on the rear where it gets more abuse.

tablatom - i remember looking for 32mm GP-4seasons a couple years back but came up empty handed.  I was under the impression Continental only made 23, 25, and 28mm versions of these tires and their 4000's; and if you wanted to go to 32mm your next choice was gatorskins.  Do you have a link/source for 32mm 4seasons?  I'd definitely like to grab a set...

Clarksonxc, can you tell where the "reply with quote" button is?
I can't see it.
Most of the German websites sell the 32mm 4season.

I had some speed rides a few years ago when the city was redoing a lot of the asphalt. I got 3 flats in a week and gave the tires away.

Nice! I would by them too at that price! The 35mm tire costs 2-3 times the price in the US compared to the 43mm (roughly 15 - $45). That makes me wonder what the 43 is missing (casing is apparently much different)

Maybe I've been drinking too much Heine* coolade, but I consider a supple ride the most important thing for a gravel bike. So, I will spend the extra $$$ to get 127 tpi.

The 43mm Conti has 28tpi. Right, 28. That is a dealbreaker for me. Still, for the price it is a killer tire.

I know!

I literally spent years looking for them, had vendors promise me they were on order, and was prepared to buy them in Germany on one of my trips over there.

But

I found them on amazon.  Order the 32 inch version (I know...).  That is the 700cx32mm.   I got 2 for the price of one (for some reason).

I agree, but paying more for suppleness while possibly getting less durability in the bargain is a trade-off to consider.

tablatom - there is a pencil-like icon next to the post number in the upper right hand corner of each post.  Click that and it will bring you to a reply page with the chosen post quoted for you.  Just make sure you type your response under the last "{QUOTE}" they provide so you don't add your response as blended in to the previous post (like Skidmark accidentally did in Post #15, haha!)

Also - to chas and tablatom - do these 32mm 4-seasons run fairly true to size?  In my experience the Continentals seem to fit as follows:

GP4000SII
23mm - true to size
25mm - true to size
28mm - balloons up way past 28mm, regardless of rim (even comes in a larger box!)

GP4 Seasons
23mm - true to size
25mm - true to size
28mm - only about 1mm wider than the 25mm version

Yep, the 32 GP4 Season are true to size

And yes, the other sizes you mention match my experience.  
I got excited when Michelin came out with a 28mm pro4, only to find that I couldn't tell the the size difference between it and the 25mm - even when laid out flat (the rubber was a little wider though).

the 32 Gatorskins are a bit smaller than the GP4 seasons.  I can get them on some bikes I can't get the 4 season on.  Then again I have some old 32mm gatorskins (wire bead) that are about the same size as the 28mm GP4000 SII.

Thanks for that info, I'm definitely gonna get a pair.  The Conti's were my first experience with "hey, that tire doesn't measure what the sidewall says it should!"

And in the way of not hijacking this thread, I did purchase a Speed Ride 700x42 last spring.  Regular $30 marked down to $22.50.  I like the way it rides; easy to mount up and fairly supple.  Kind of like a bigger version of the Challenge Gravel Grinder.  I am still a tube guy, so no comments on running with sealant.
