MPCC has no plans to call for ban on carbon monoxide rebreathers in cycling

The Movement for Credible Cycling (MPCC) currently has no plans to call for new rules against the use of carbon monoxide breathers, a practice which has been a topic of considerable discussion on the Tour de France following an Escape Collective report published during the second week of the race.

The device allows for the precise dosing of carbon monoxide into the lungs to measure haemoglobin, but concerns have been raised that the practice could eventually be abused for performance gains.
