Schwalbe durano is a better high-mileage, puncture resistant,more supple,better fitting tire anyway

That's what GCN is. They're part of a new-media advertising agency, where the model is to make viewers think they aren't watching adds.
>>
>>1254905
Many of GCN's videos have a "includes paid promotion" disclaimer at the start. Must be a youtube video flag because it isn't embedded in the video and isn't re-shown if you go back to the start.

Most "GCN rides a brand of bike you've never heard of before" episodes fall into this category.

>What did they fuck up on the GP5k?

'Different, therefore worse' kind of thinking. The flip side is the 'Same brand, therfore good'.

Essentialy - there is a reason why, for example, Spesh keeps its big mountain bike named 'Enduro' in spite of it being completely different with each product refresh. Same thing - XTR from 1997 is completely different product then XTR 2018. But - same name, thus normies associate them.

In essence - successful brand sells its splendor to its successors.

Conti should have named it GP 4000 Pro, or some such.
>>
>>1254862
Just after I bought GP4000RS. Whatever, I probably wouldn't even feel the difference (if there's any).
>>1255555
Check'd.
>>
>>1255555
After the last few series of tires where pretty good, I doubt they fucked this one up.
After all it is not a radical new design, but just the latest itteration of this series of tires.

Looking forward to see unbiased tests of that tire...
>>
>>1255658
Have there been biased tests already? What did they find?
>>
>>1255664
I am not aware of any tests outside of Conti's R+D lab claiming 20% less rolling resistance.
Obviously that is kind of biased and other biased tests aren't going to tell me much, but unbiased ones like this dutch (?) guy who does it as a hobby offer some usefull information.
>>
>>1255658
it sounds like it is a radical redesign though
did you even watch the vid?
>>
>>1255674
Anon, this is called marketing.
The overall construction is pretty much the same as in the GP4000 SII.

already in GP4000 SII

hey /ett/ interestingly enough i was hanging out with a shop owner and we happened to drop by a wholesaler warehouse when these just came in.... literlly hot out of the box

at first i was like Pfffft maxxis road bike tires.... yeah i dont need no refuse thanks... but yeah turned out they brand new, fast, 120tpi and 210 grams ! i was like fuck yeah hook me up

so i snapped up a pair at a stupidly confidential price. i really like them. Solid good value fast tire. my $0.02.

as a counterpoint to this maxxis shilling i want to say that i switched from wire bead paselas to maxxis gypsy and detonate touring tires at a shop on tour because i had to and that's all they had in 30-40c range and it was like night and day on riding not being fun or comfy any more

fuck maxxis and fuck jannies

my point is they arent terrible so good job maxxis on upping your game

>>1256573
how observant. yes i had gators because its used as a COMMUTER and it came with a new fresh pair when i bought it off my brother

i actually ponied up for new tires even though the gators werent even close to worn because of all the gatormeme schreeching i get from this place... happy ?

Looking for a 25mm tire that will reliably carry a 265lbs man through a post-apocalytic cityscape riddled with glass and potholes. Needs to take 120 psi regularly to avoid pinch-flats and have excellent puncture resistance. Comfort, speed and price is not a priority.
So far I'm undecided between the Continental Gator Hardshell and Schwalbe Marathon Plus.
I am aware that 28mm or more would be better suited for the job but 25mm is a very tight fit already. Mid-80s Panasonic DX-2000 road frame.
Thanks in advance, guys!

Nah. Just be aware that all the videos highlighting products are biased. There's still good content on the channel.
>>
>>1254955
Who cares? Most entry level "training" tubulars are really good gripping tyres with decently supple casings, and there's plenty of respectable tyres in 23mm size from challenge, veloflex, conti, Victoria etc.
Gotta have dat removable core and slime filling though for practical use.
Maybe they're not trying to attempt to sale them for track use in a 23, as velodromes aren't fond of people working silica tyre marks into their nice wood surface.
>>
>>1255690
rude
>>
>>1256621
Tubular != tubeless m8. Also the market for 23 mm tires definitely is still there, especially for higher performance tires as 23 mm tires are optimal aero on pretty much all modern wide rims.
>>
>>1256624
I was under the impression modern wide rims were optimized for 25mm tires? In fact on a recent GCN video some guy from Zipp said 28mm was the optimal width for their deep dish wheels
>>
>>1256626
The marketing people say that because freds are scared of narrow tires, partly because the marketing people have memed wider tires for a few years already. If they said you need 23 mm tires for optimal aero they would lose massive amounts of fred sales. The fact is that on 99% of rims out there 23 mm is going to be faster than 25 mm. On wide rims most tires balloon a few mm wider than the stated width so staying below 95% of rim width for optimal aero can only be achieved with 23 mm tires.
>>
>>1256630
23mm tires are just full retard now for dumbcunts stuck on old memes
>>
>>1256635
Not at all, on smooth roads 23mm still rolls faster than 25 or even 28 mm and has less aerodynamic drag and weight.
Larger tires only roll faster than smaller ones on rougher surfaces since they have higher deformation losses, but lower suspension losses.
The more road-buzz the tire has to absorb, the larger it is supposed to be.

Here some recomendations for different surfaces:
>velodrome
19 mm, rockhard
>road, smooth
23 mm, high pressure
>road, normal
25 mm, medium pressure
>road, rough surface
28mm low pressure
>cobblestone, paris roubaix tier
2-3" XC MTB-tires, low pressure
>>
>>1256643
The weight of rider + bike is a factor that you might be forgetting though.
The more weight you and your bike add up to, the more air volume the tyre needs as a cushion against road conditions. A given amount of air is always going to fit in a bigger tyre at a lower pressure, and have more grip and handle rough surface better, though at a weight penalty.
I use a rough formula: the bare minimum tyre size for road going bikes is weight in kg of you and bike divided by 4 and then add 3mm to your result.
Then, using this rough chart (I understood a bit), you can work out your pressures and weight distribution.
Keep in mind this is a chart for weight on one wheel and not total weight, so you'll need to find your weight distribution out via a scale and simple maths.
>>
I'll get some, but but both my road bikes have brand new 4000s and 2 more new spares in the parts bin, so it'll be a while.

Riding with Vittoria Voyager Hypers on my commuter rn and they've served me well for the last 3000km. Now that it's winter I'm finding them incredibly slimy in the wet. Road iron especially I have zero grip on if there's water around.

Are there any recommended slicks in the 35-40mm range that will offer me a little more grip for winter riding?
>>
>>1256643
19–23 are basically velodrome-only in the real world, unless the rider weighs 60 kg or less
>>
>>1256653
Anything with a file tread. Panaracer is a good go-to brand

This. Corsas are GOAT.

I would be interested in trying tubeless on the road once, but I doubt it would feel better than Corsas with Latex tubes.

650B conversion. 584 mm BSD tires are available down to 32 mm width, at the cost of some reduction in bottom bracket ground clearance.

Alternate option: Soma Fabrications New Express 700x26C
>>
>>1256647
I was assuming a normal rider weight of 70 kg plus 10 kg bicycle.
Heavier riders need to increase their pressures accordingly, but the tire siezes stay the same.
(unless you are a 80 kg+ hamplanet)
>>1256661
19 mm indeed, but 23 is prefect for good roads.

i like your extremely practical bike, and as such will bestow upon you some knowledge

10-speed sram mtb rear derailleurs and 11-speed sram road read shifters have the same pull ratio: i use an x5 rear derailleur with force 11 at the front on one of my bikes and can take an 11-36 cassette with that setup. i'll be matching an xo rear with red 11 on my next. also, the cable routing is much, much cleaner on the mtb kit, similar to shimano shadow geometry.

10-speed xo rear derailleurs regularly go for very little on ebay because no-one wants 10-speed kit any more. there's a 20g weight difference between them and the red 11 model, and you save that by default as you use less cable.

i don't know why more people aren't running a similar setup - i tried it first without knowing for sure it would work after looking at the numbers in this article:

http://blog.artscyclery.com/science-behind-the-magic/science-behind-the-magic-drivetrain-compatibility/
>>
>>1256669
Thanks for the advice, man, but my BB is quite low already and due to the fact that I'm 6'6 I dont want shorter cranks than 175mm. Also, I really don't want to buy new wheels. So 650B conversion is out of the question.
I'll look into the New Xpress tires you recommended, but apparently they're quite hard to come by in Germany.
Looks like I'll have to decide between the Marathon Plus, Gator Hardshell and GP4S.
Currently strongly considering the Marathon Plus because I really like reflective sidewalls...

The Somas are built by Panaracer, who also manufacture "Jack Brown" tires for Rivendell & On-One/Planet X (UK) as well as the tires for Fairweather (Japan).
Any Deutsche/Central European distributors for the above boutique brands?
>>
>>1256847
This could be a viable option with butyl tubes, compatible sealant, & a Presta injector (Tirejector?)
