Comfort close to tubular with challenge tire (Translated review)
No negative feedback for now, very flexible, easy to mount, to see over time. (Translated review)
very good quality price very flexible in handling I recommend for cyclo cross (Translated review)
Hello, very good product. Jean. (Translated review)
One of the two inner tubes delivered showed a structural defect right out of the box, probably related to the protective cap (misnamed). An inflation test immediately confirmed the defect with the appearance of a balloon-like area. Almost impossible to mount, inevitable pinching upon inflation, straight to the trash. (Translated review)
bought 4 chambers after 10km done by my 50kg boys, 2 of them burst and are not repairable. so for me, bad quality, do not buy (Translated review)
After about 400 km the sensations are good. Lightness and reliability. You need to pay a bit more attention to the pressure. The installation is a bit more complicated than with traditional tubes. Good product. (Translated review)
I use it for mounting in tubeless tires because I no longer trust tubeless (too many issues recently). Light and comfortable. It deflates over time but it doesn't bother me to inflate it again for my gravel use. But I feel like it's sensitive to deformations like bulges? We'll see over time. (Translated review)
Very light chamber, comfortable, but be careful with the assembly, it pinches very easily. (Translated review)
good product, I need to ride more kilometers to test it better (Translated review)
