Will I get used to the weight?

How much does the rack weigh? If you don't use it, you should lose it.

It weighs 640 g, just a little over a pound. I do use the rack regularly but for the long rides, I could ditch the rack.

It would be better if rider could lose some weight so that my bike wouldn't feel like a freight train going uphill.

OK, maybe not a freight train.
