I have the same setup but at 77kg have to run them above 80psi, it rides really well. As for the durability of the tubes I am not sure, in 1500km I have had one pin hole puncture that repaired no problem and last week I hit a pot hole and got a snake bite on the rear, to be fair it was a very hard hit at 40kph that made a bottle jump out.Titanium22 wrote: ↑Fri Sep 11, 2020 8:06 pmUpdate:
I've now done around 1500 miles on 25mm 5000's (215g), fitted to Enve 3.4 rims not the AR model.
Front and rear measure 27.7mm
I'm using Tubolito S tubes 23g
I had to play around quite a bit with the pressures I'm now running around 70psi, but they are now comfy, grippy and reassuring. At higher pressure they seemed abit skittish and harsh. I have had no puncture's or pinch flats, no damage, and no shards or flints stuck in them. They still look newish, but the rear has started to square off a little. I weigh 66kg, and often could get 7000 miles out of some Gp4000 sII's with the wear markers just still visible. I'm not sure these will last as long.
The tubes I was sceptical about, but so far so good. They hold air about the same as a butyl 75g Conti race 28 light.
Gp5000 plus tubo S weighs in at 238g. Gp5000 tubeless is 295g + Valve 10g + Sealant 40g = 345g
So GP5000 Tubo S saves you 214g per pair, rolls just as fast, must climb a bit better? At my weight I can get away with 70psi, the same as tubeless, but if you are heavier you may need to go higher than you would with tubeless. No hassle setting up the tyres. No Mess and no sealant to replace. I haven't tried the patches yet, but will update when I one day get a flat.
If it was a normal tube I wouldn't of bothered to even try to repair it but given the price of my 'orange condoms' as they are called by my mates, I tried a repair unsuccessfully. I will try again but the patches I will use cost as much as a normal tube...
