NEW GP5000S TR

[warthog101]

I run 50 (F) and 55 (R) on a Zipp 303 Firecrest for a 28mm GP5000 STR. 66kg.

You can try SRAM's calculator as an alternative too.

Sounds fair enough with wide internal rims.
I have a 28f and 32r on my 25int 32ext hookless WR50s. (not GP5kSTR)
55psi at each end is plenty of pressure. I am 78kg.
The 32 is huge on those rims though. Will drop down a size or 2 when it wears out.

I tried 85psi front, 90psi rear yesterday. RR still felt good.

Today, if I manage to get out I'll go with 80psi front, 85psi rear.

I have to say that I'm very happy with these tyres on the Bora WTO. Perfect fit and useful speed gain for me. They are also light and feel tough. Let's see how they hold up.

What width is the 32 measuring on that 25mm internal?

I meant when you fitted a 32mm GP5000s TR to your 25mm internal rim bed what width did the tyre measure?

Sorry it is not a conti tyre.
It is a Michelin power road.
It is 35mm wide.
I replied with respect to tyre pressures on a wide rim. They don't need to be as high as the tyre and rim width gets larger.

I tried 85psi front, 90psi rear yesterday. RR still felt good.

Today I went out with 80psi front, 85psi rear. The feeling of super low RR is gone, but numbers indicate it's a bit faster than a Rubino Pro with inner tube. Comfort is better over rutted road surfaces though.

So I guess it's a trade off (as expected), higher pressure = lower RR at the expense of some comfort.

Nice! Decided to test lower pressure as well. 77 Front and 82 Rear felt like the lowest I could go while still benefiting with RR and compliance

83.9 Kg and run 85-88psi front and 90-93psi rear with 25mm GP5KS tubeless

32mm GP5000 S TR on rims with 25mm internal, 30.4mm external but 32.4mm at its widest measure 34.5!

I reckon 30mm GP5000s TR tyres should mate best

They are the Beast GR40 for anyone wondering

Mounted Continetal GP5000S Tr 28mm on my Zipp 404FC disc wheels. They measured 29.5mm and mounting was not that easy, but not realy hard also. 59 psi in both tires and when the weather is better I will do the first ride.

Today I mounted the GP5000S TR 25mm on my Farsports Feder disk wheelset. The installation was accomplished relatively easy without using tire levers. They retain air very ell even without sealant. First impressions: The roll a bit faster(?) than the Schwalbe Pro One Super Race at least in terms of feeling... Yet, they lack a bit in terms of comfort. I noticed some road buzz at high pressures (100 psi at the front and 110 psi at the rear). I need as low as possible RR for now..... Very happy in general

What size did they come out on the Feder wheels ?

How easy/hard was it to mount those 32mm TR? Levers needed?

By hand, no issue
