If I can add to the weith issue it is more important to remove weight off 
something that is moving then what stands still. It goes with the example 
given of using dumbells. It would be better to take weight off your wheels 
then taking weight off your bike frame or even body frame ( though off the 
body would be healthier if over weight). But be careful. Removing so much 
weight off the whees may make them more accessible to breakdown. So ask at 
the shop before making changes.
