In reality you will loose a little power, its virtually impossible to loose 15kg without loosing a little muscle along with the fat.toolonglegs wrote:Silly question but maths was never my subject...if I can hold the same power but lose 15 kgs (from 100kgs to 85kgs) will that improve my power to weight by 15%?....being 100 kilos makes it easy to work out I suppose .
don't forget to include the bikes weight in the power to weight ratio.
15kg equates to about 2kph faster on the flat, but as you know it will equate to a huge improvement going up hills.
