It’s not just the wheels.
The neuron is a trail bike and not a race bike so it’s the beefier frame,fork and the geometry of the bike.
your friends are on 100mm race bikes that are made for speed.If that’s what you are wanting then sell the frame and fork and buy something lighter or swop the bike.
I love my neuron as a all round bike but I’m not a race snake and just enjoy the riding.
ps mines at 12kg at the moment🤫😳
