New Continental 5000S Tires - Tubeless Compatible

[Monkeyfudger]

The choices of pro racers be that XC or DH are largely irrelevant to the average rider as they’re generally riding so much harder, notice I said ridiculously soft tyres, you see them on the trails with their tyres squirming on the slightest corner, they’re the same people that run forks/shocks soft to get that mushy “plush” feel and complain they blow through their travel on a 4 foot drop

Also, at the same time some of the choices of pro XC racers can be ignored..is someone truly better off running 300g carbonz when they have to put a 200g insert in to protect their rims?

I’d be willing to bet the guys getting a lot of sidewall cuts are running their tyres fashionably soft and maybe also not quite being honest with themselves about their weight it’s getting to be the same in MTB, dudes running ridiculously soft tyres for the gripzzz but pinch flatting *f##k* out of tubeless so we’re now seeing foam inserts :eyeroll:

You callin' me fat, pal?

solid... big boned..

Wondered how long before there would be something like a 'do these tires make my bike look fat' kind of post.

200g?

How about a third of that.

I edited after posting. MTB riders have been doing gravel long before it was called gravel and Paris Roubaix riders have been doing extreme gravel since day zero. The first bikes where gravel bikes. Gravel tyres therefore have been around along time. They're called road tyres.

The biggest tyre I can fit under my mudguards is 28mm wide and 25mm tall.

And nothing has changed in tire design since “road riding” then and now

That is now gravel racing.

PTN inserts are 100g, normal riders think they dont benefit from inserts but they have not tried them or tired the wrong ones. Some try pool foam barriers and when that does not work they think all inserts are marketing bullshit. However these folk are wrong. I am a normal MTB XC rider. nothing extreeme here in suffolk and the difference with a good insert is night and day. Thw weight of the insert is irrelveent as it allows you to use a lighter tyre anyway instead of that heavier trail tyre.

So, you're saying that a lightweight tire would hold up under those same trail conditions that drove you to use a tire insert without said tire getting torn up?

[bm0p700f]

In general yes. Of course I never tear up tyres. The main reason for inserts for me is improved handling. The rim and tyre defence is a side product for that. Given with an insert the sidewall flop less a lighter tyre can be used withing reason. Some riders are so hard on there bike that nothing survives them.

GP 5000 TL 2nd fastest tire, very close to Corsa Speed, in Jarno's Test =0

Anyone have the 32s in stock yet? Seems I need to get a pair for my new build.

Pretty impressive! The Corsa Speed is hard to beat but it's not a surprise, cotton casing, a rubber thread so thin that's very fragile with such a short lifespan, the GP5000TL's numbers are really good given it's one of the longer lasting performance tires you can ride daily.

[Monkeyfudger]

I’m torn at the minute, I’ve been using Vitoria Speed’s (tubeless) for a couple of years now but you can damn near see them wearing out after a ride and despite never getting a puncture I’m always a bit weary, thinking about GP5000’s but they’re bloody £15 a tyre more at the minute! Hoping they’ll come down to the same price as the Speed’s.

[petromyzon]

Truly impressive numbers. Enjoying my Corsa Speeds but these figures make them look like an expensive folly.

[bm0p700f]

The conti do feel fast when I am on them. They are proving however not be robust. Conti have created a quick tyre for sure that is probably robust enough for most but not an all season tyre. It's a race tyre.

They became very slow tyres on Wednesday night when the from lost all its air in about 20 seconds.

They used 50mL

I also thought that was excessive. Let's wait for Jarno's test, but I don't think it'll get that much faster.

Jarno uses butyl tubes, which are maybe 1W slower than latex tubes using his test protocol (29km/h, 42.5kg load.) He also uses 20mL of sealant which is what I consider the absolute minimum to run on 25mm tires.

Aero Coach used latex tubes and 50mL of sealant. Their test is performed at 45km/h with an unknown load. Given the wattage difference in the two test protocols, the difference in rolling resistance between the two tires according to Jarno's test would be just a fraction of the 1.2W from the Aero Coach test. Now add the penalty of a butyl tube and I think the GP5K TL scores in low 9s on Jarno's test.

I knew it was going to be very fast. Turns out logic and physics work the way they should. I just hope the reduced tread thickness still results in endurance competitive with the Fusion 5 Performance...and no sidewall tears (the inner liner should help.)
