Neutron? Neutron? is the classic expression of the wheel for time trials over hills or century rides, while remaining suitable for any competition except fast time trials. They are rigid laterally but vertically elastic, thanks to the asymmetry of the rear rim spoke drilling and the special rim section design. They are strong and long-lasting, thanks to the quality of the design and materials which have allowed optimization of all the parameters. The lateral machining of the rim provides a top level braking surface, while the butted spokes and aerodynamic profile means they are always swift. The Record? class hubs rotate on very precise adjustable 15-ball bearings and have a new generation body. Release system with bilateral-acting light-alloy lever.
