All I know is that my ’07 Five weighs less than an ’11 Five* (when picked up side by side)
My pro spec Five is built reasonably light were as the ’11 Five has a heavier frame due to tapered head tube, fatter tubing and the pro spec demo bike had slightly heavier components.
I think my bike weighs in at approx 27-28lbs so 30lbs makes sense. I can understand why people are interested in bike/frame weights but they all still need legs and lungs to make them go. So if the new Five is heavier you’ll just need to improve your fitness and strength. Like most things, the body adapts accordingly.
I’ sure the extra weight will be forgotten as soon as you scare yourself silly on the descents 🙂
*By no means scientific proof 😉
