Hey guys,


got my first road bike 2 months ago, and I am now chasing those KOMs, so naturally I am looking on possible improvements.

The TCR Advanced 2 comes with Giant Gavia Course AC 1 tubeless tyres.


So far they hold up great over probably 800 km, without any visible punctures. I ride in dry conditions and have had no grip issues.

I have read that upgrading the tyres might be the cheapest speed upgrade.

Would it make a real speed difference to switch to for instance Continental GP5000 TL, or does it not really matter too much?

Would those be as tough as the Gavias, or might they puncture easier?


When buying Conti GPs, would I have to put sealant on them? I am a bikenewbie, and the Gavias have not required sealant, but that might be applied in the factory?


Thanks a lot :-)
