Replacement for GP4000s?

[warthog1]

I have a couple of P Zero Race TLRs on the way.
I am the opposite.
Love road tubeless and don't want to go back tubed.

I am the same

Somewhat irritating is that the Pirelli P-Zero Velo looks like it's discontinued.

The P-Zero range is now -

Race (lightest)
Road (better puncture protection)
4S (all weather)

Road and 4S weigh roughly the same (240g), about 30g per tyre more than the Race

The Velo 28c weighs just 230g (I think the weights you quote are for 25c, Velo is 210g in that size) and is faster than the Race (see BicycleTireRolling Resistance). So Pirelli dropped the superior tyre.

[Mr Purple]

As above - my warning to you on the Pirelli P Zero Road is that they're absolutely awful in the wet. As in unable to climb out of the saddle at all, and regularly slipping around all over the place even in gentle corners.

30km in the wet on Saturday on mine and it's now on the front of the trainer bike. I will never ride with one on the road again, that's how bad they are. If I hadn't had a GP5000 on the front I don't think I would have made it home.

The 4S might be worth a look. Their rolling resistance is only very slightly worse than the P Zero Road and they presumably grip better. Weight is about the same too.

As above I used to like the P Zero Velo as well. Their rolling resistance was substantially better than the P Zero Road, and I swear the wet grip was better. Or I've got fussier, one of the two.

[MichaelB]

Did better with the current GP5000 rear. 1044.7km before bits started falling off it.



That's the only canvas showing for now, but from experience it's going in the bin when I get home. Things tend to go downhill pretty sharply from here.

I'm putting on a new Pirelli P Zero Road and will track the mileage as well.

I don't understand your lack of decent Klms out of tyres.

Methinks you need traction control on the treadly ....

Currently riding a lightly 2nd hand set of Vittoria Rubino Graphene 2.0 3 (I think) tubeless in 30mm - have done almost 3,000km this year lugging my very lardy posterior all over the Adelaide Hills and nary a bit of wear to show

Edit : Corrrected tyre type

Mind you, the only cups I get a HR ones rather than Strava or Power ... (FTP is only around 260W)

[Mr Purple]

Well our FTPs are the same then!

It's been suggested that I'm climbing with the weight too far forward - probably a legacy of my last bike being a bit short and tending to lift the front if I didn't.

It's surprisingly hard to fix that, but I'm working on it. It does make sense that it's not an outright power thing but an imbalance between the power going through the tyre and the weight keeping the tyre on the road.

[MichaelB]

Well our FTPs are the same then!

....

Yeah, but I'm not 60kg ...

[MichaelB]

Finally got out to the shed and did a stocktake on what tyres I have in storage ...

- 2 x Vittoria Corsa Control Graphene 2.0, tan wall, 30c (new)
- 1 x Vittoria Rubino Pro Graphene 2.0, TLR, black, 28c (lightly used)
- 2 x Schwlabe One, TLR, tan wall, 28c (new)
- 2 x Continental GrandPrix GT, black, 28c (new)
- heaps of tubes ....

In use now ;
- 2 x Goodyear Eagle Sport, tanwall, 28c
- 2 x Vittoria Rubino Pro Graphene 2.0, TLR, black, 30c

Once I've finished up using the 28c, 30 or 32's will be my preferred size.

[Mr Purple]

1460km out of the rear GP5000, a new record!

It wasn't dropping chunks at that point either, but the wear markers were completely gone and it was looking pretty paper thing.

Have put on a Vittoria Corsa, we'll see how this goes. I suspect 'not particularly well' though they do ride nice.

I've got 2 of the Vittorias in 25c that came with the new bike. Wet weather grip seems on par with the Conti 5000s so I might leave them on when the replacement frame arrives.

Dear lord that's incredibly low mileage for such an expensive tyre

Good luck to you and your wallet with the Corsas!

That's better than usual for me. My record is 850km - with big chunks missing from a GP5000 at that stage.

Part of my worry considering tubeless - I'll be pretty annoyed if my tubeless mileage is the same, because the tyres are so expensive.

That's crazy low, I have about 6000km on my GP5000TL, the rear is a bit squared off but I haven't hit the bottom of the wear markers yet. I fitted the front in September 2020 and the rear in February 2021, I even bought some Corsa in January in preparation for the tyres either wearing or failing catastrophically, but they keep going.

2/3rds of my riding is on the Veloway so maybe that makes a difference?

[warthog1]

I have run a couple of GP5TLs out.
Around 4k km out of them.
Mr Purple is standing and smashing it up hills in his quest for more KOMs.
I expect that is unweighting the rear a bit and the tyre is slipping on the road under power.
He is a fast rider putting tyres through significant stress with all that high power climbing.
I dont expect any tyre to last under that sort of punishment.
I don't see tubeless being any better under that sort of treatment so it is probably going to be an expensive exercise if that is that type of riding they will be applied to.

[MichaelB]

Given now that the 30mm tyres fit well on my two new steeds and I'm not becoming a lightweight anytime soon , I'm clearing out my excess stock of 28mm tyres.

Both are BN without box, and haven't been installed.

Both are aimed more at the sportive market than race day tyres. Can supply pics if you wish.

Happy to a deal for all 4

Cheers

Michael

CONTINENTAL Tire Grand Prix GT 28 "| 700 x 28C BlackChili PolyX-Breaker
The marathon runner among the Grand Prix tires. This makes it the first choice for big tours and long practice laps when the roads are not necessarily as smooth as a highway. The extra-wide PolyX Breaker effectively protects against foreign bodies under the tread. The continuous three-layer carcass effectively reinforces the flanks without much added weight. This gives the Grand Prix GT exceptional staying power, making it ideal for marathons and multi-day races.

[Mr Purple]

So I'm up to 1030km on my first rear Vittoria Corsa.

Very impressed - not a lot of wear, which is great considering GP5000s were usually up for replacement at this stage.

I think they're a little bit stickier than GP5000s which suits me. I have come to recognise a 'scuffing' sound uphill under extreme power though and modified my riding to be a lot smoother to cancel it out. I'm pretty sure it represents me picking up the rear tyre under power, which is obviously a killer of rear tyres.

Now I try to think of the 'scuff' as the cash registers of the tyre manufacturers 'dinging'. Hope to get at least 1500km out of a tyre now. Still haven't fitted one by the side of the road, which is my main worry regarding the Vittoria Corsas. On the positive side; this also means I haven't had a flat.

Were they hard to get on? My Vittoria Corsas go on fairly easily* (my Challenge Stradas, on the other hand...)

* older version though, so things may have changed.

[Mr Purple]

Yes, they were. Apparently it's mainly the first fit though.

Having said that I struggle with most tyres. Pirellis were the only ones that went straight on.

[warthog1]

The tubeless is a far more reasonable price than the GP5kSTR.

https://ccache.cc/products/vittoria-cor ... full-black

I am not paying $130 aud for a tyre that lasts 4-5k km.

[Mr Purple]

Those tubeless Vittoria look like a good option, I'll see how the TPU tubes in the ones I've already got go first.

Have been riding my spare bike with a fairly new GP5000 on the rear while the good bike's being reframed. I think I can confirm that the reason I kill GP5000s is because they spend a lot of time 'scuffing' around at the back, I think they're just a little too hard/not grippy enough and so I lift them off the ground a fair bit which obliterates them. They definitely roll faster though.

1200km on the rear Vittoria Corsa, hoping to get to 2000km if I ever get my bike back.

[warthog1]

You aint getting your bike back. It is a new one.
Your wife doesn't read this forum (hopefully)

[Mr Purple]

It is the same bike, it just has a new frame!

I must admit I have actually renamed that bike 'The Ship of Theseus' on Strava.

https://en.wikipedia.org/wiki/Ship_of_Theseus

If only because that's the only way I could monitor the mileage of all of the parts independently of the frame.

I like Triggers Broom better ....

I have the same issue with some of my parts transferring from the Original Volagi Liscio to a Kinesis and then to another Volagi Liscio before on to the Vigorelli, of course with some components being replaced. And the wheels are a good example - the Farsports Rims have been built into a few variations of hubs over the time and on various bikes ....

Actually, probably the ONLY original part from the 2013 build of the original disc Volagi Liscio .....

[Mr Purple]

One of the guys I work with has a Van Nicholas that is literally just the original seatpost. My goal is to beat that.

I bought some Lifeline Prime Armour 28mm (120TPI) on special for 30 'quid'
https://www.this link is broken.au/lifeline-prim ... -road-tyre
Put one on a wheel today... doesn't seem quite to 28mm width, but it seems ok for the money.
Has anyone tried these ?
I might try and find a spare rear wheel to match it up before i take it out for a spin.
