MTB bike weight

[TNT1]

Bike weight does make a difference But 1.5kg saving on a road bike from 8kg down to 6.5kg is a bigger saving in weight than for a MTB from 13kg to 11.5 kg (bare with me this isn't ANC maths.....)

 

For a 80Kg rider the the all up weight on the road bike will be 88kg vs 86.5 or a 1.7% saving

On the MTB its a 93kg vs 91.5kg or a 1.6% saving.

Overall its probably immaterial so within the context of a a bigger heavier rider the weight savings is a small change and there are more gains to be achieved in increasing power. Your bikes weight is the least of your worries

The lighter the rider is the more important bike weight should be to that rider.

The heavier the rider, the more important power output should be
