i finally had the tyres off today and discovered inner tubes much to my disgust. upon refitting new tyres with no tubes i found the tubeless valves i had ready were too big,maybe they are for cast wheels not spokes. The excel rims have tape inside the rim already, so did the Amazonas come with tubeless as standard , i would have thought so , so why has someone put tubes in here? It was too late to run around and get valves and i wanted the bike running for the weekend so i've very angrily put the tubes back in for now.
What's the verdict on tubes , they are Pirelli hd tubes, shall i leave them in, if i puncture maybe a tub of slime will seal it. Really pissed off at the thought of taking it all apart again but i can't see the point of inner tubes, only drawbacks.
