Purchased because of the 3-day Ardenne Gravel Stages race with very coarse gravel. Total zero punctures!!!
Chosen obv reviews in trade magazine. To replace Bontrager GR2 Team Issue 700X40C Skinwall 18/4 Received new ones under warranty. First set from 05/2023 appeared to have become porous, spring 2025: latex pressed through skinwall! Tyre pressure dropped from 3.5 bar to zero within 4 days. 21/4 New set put on with Vittoria Airliners - no ride yet. Tyres are still under pressure. PS: Airliners work better with 40mm tyres!

Big crack after 3rd gravel ride. Hopefully a rare case of pure bad luck, as it really did roll nicely over gravel paths, in the forest and on asphalt. I'll order it again because first impressions were good though. Also looks nice with brown skinwall under black Trek Domane.
To replace the original Bontrager tyres on my TREK, I ended up with these tyres via fiets.nl's test. During the first ride, I was surprised by the grip and rolling resistance of these tyres. On a mountain bike course with nice single tracks, I was not afraid for a moment that I would lose grip. On the road, rolling resistance was not disappointing either. Tubeless mounting was also very easy. Without fluid, I didn't even have a leak. What is a pity is that they are only offered in two widths. Although 38 mm is sufficient in most cases, I opted for the 44 mm so that I can also cope with rougher terrain. 40 mm would have been nicer in my opinion. Finally, the decals on the tyres. In my opinion, the brand name should have been on the same spot so that they are visible at the valve from both sides (see photos). The tyre would then have been perfect (therefore 4 stars).

Furthermore, the decals are a bit emphatic so the look of the tyre is a bit less. That is a matter of taste.
