Time to upgrade stock tubeless tyres

Hello,

I have a Giant TCR Advanced Pro 1 (2018) and I am looking for a speed upgrade. Currently considering options for upgrading the tyres that came with the bike.

I am currently rolling on Giant's own brand Gavia Race 1 25mm tubeless (307g) on Giant's own SLR 1 carbon rims (1380g for pair). They feel ok, but have limited experience so nothing to really compare them with.

Firstly, would a tyre upgrade offer any performance benefits and if so, which tubeless tyre would work best with these rims? Bearing in mind I would take any new tyres to my LBS to get them professionally fitted. I've been looking at tubeless tyres from Continental, Schwalbe and Giant's own, higher end offerings. Is it purely down to weight or is the type of rubber compound more important? Obviously I got a racing bike so performance is more a priority for me than durability.

Also, how often are you supposed to change the sealant? I've had the same sealant in since I brought it a year ago and haven't had any punctures yet (touch wood).

Many thanks.

    For tubeless tyres look no further than IRC roadlites available from thecycleclinic.

    Same wheels on partners Liv, replaced the stock Giant tyres with Pirelli Cinturato, fairly good rolling resistance, not the lightest but good puncture resistance . . . the other option was GP5000 TL with almost the least rolling resistance of any clincher, but couldn’t get hold of any at the time . . .

    Hutchinson Galaktic would get my vote.

    My LBS says I should have a sealant check every two weeks. I also have Giant wheels with Gaviatyres.

    I've run IRC Formula Pro 28s which were ace. I've replaced them since with the Cinurato but only because I was looking for bigger tyres and these came in 35s. If the Formula Pro cam in 35mm no question it's what I'd be riding.

    Hutchinson Fusion 5's are decent tyres and don't cost as much as other tubeless tyres. Lots of grip and seemingly not too much rolling resistance.
    I've done about 2,500km on my current set and they're starting to round off, should have some life left in them.

    With regards to the sealant, I check mine every 3 months or so.

    I have narrowed it down to these three (all 25mm):

    Hutchinson FUSION 5 GALACTIK - 250g
    Schwalbe Pro One - 255g
    Continental GP5000 TL - 295g

    Looking at weight difference, is the GP5000 going to be a slower tyre with it being slightly heavier than the other two, or is the rolling resistance more important? The GP5000 is still lighter than my Gavia Race 1 but only by 12 grams.

    The GP5000 TL is the second fastest tyre tested here: https://www.bicyclerollingresistance.co ... 00-tl-2018

    Weight is irrelevant.

    The Galactik is much more of a TT/Race tire than the other two and won't last as long.
    Grab the standard Fusion 5 instead.

    Id go with these, Corsa Speeds are too fragile
    I'm sorry you don't believe in miracles

    Nicleza I normally check mine annually or when a tyre is changed and certainly not every couple of weeks. Only thing I check that frequently is that nothing's stuck in the tyre and its up to pressure.

    How long did they last?

    Haha that's a big difference. I won't die of anxiety for not having them checked every two weeks then, but I think I will have them checked more often than once a year :).

    What difference did you notice with the Formula pro Tyres compared to the Giant Gavia?
