a 1% reduction in weight was good for 30 seconds.
...or rather less than 1% of time. Weight matters, of course, but let's face it, working on the rider - in terms of both weight and fitness - is for most of us going to make far more difference than spending money on the bike. When I can put out 5w/kg, then I'll start worrying about the fact that my bike weighs 8kg.
Which will be never, btw.
