When cycling uphill, power-to-weight is king. But is power or weight more important? A few months ago, Ollie and Alex did an experiment to see how much difference 1kg makes on a climb, and now Ollie is at the epic Laghi di Cancano climb in the Italian Alps to see how much difference 5 watts makes when climbing.

250 Watts, I can talk normally! I am ☹️
This pretty effectively proves that weight weenies are mental, whether amateur or pro. These dudes are obsessed with 0.1kg or lower differences (hi Tadej!), but even going with a bike setup with say 30mm deep rims vs 50-60mm depth to save 250g, it’s shooting themselves in the foot! The aero benefit at pro speeds from the deeper wheel will be much larger than the barely if at all noticeable slower climbing time from the 0.250kg higher weight
Ollie, does it matter how you make the power? Ie what gear? In my head 250w in a easy gear won't give as much speed as 250w in a hard gear. I know it comes down to cadence at the end of the day to generate the power.
How about an aero sock test. Does it make a difference? At 200w for us meer mortals.
Watching this even though my most common bike ride has 130-140kg on road (mtb, rider, kid on back trash talking my speed, stuff)
As a 95 kg male i could really feel the difference after lightening my bike by 300g it makes all the difference. Had a couple of pints to celebrate
what kind of amateur counts seconds?
Ollie can talk at 250W, I can't ☹️
Exactly the content I'm looking for and why I'm a fan of GCN!
250W ... I wish
Hey Ollie, great video, sound data. Have you thought about applying this to eBike battery range? Not the throttled ones but the Hybrids like Wilier is producing. We are seeing a difference in philosophies among eBike manufacturers with some making bigger, more powerful batteries and increasing overall weight vs. Wilier’s approach of lighter, more responsive bikes with ultra light motors. I’d love to hear your opinion and see testing on this.
Inflate your tires more. It's a lot easier.
Hi Ollie, I love how you keep destroying "old cycling myths" : moving weight, tire width, and now +5W > -1kg... It's just so fun to bring these on the table with experienced cyclists that were always told the opposite... Good luck convincing them even with these kind of tests !
Weight is everything
Have been enjoying your videos over the last few years Ollie and finding them pretty inspirational! Could you let us know roughly what your weight in kg is for some context?
My first reaction was: guys you’re nuts, it isn’t possible.
Then I could finally test it myself by buying a new bike (the Cervélo S5 you featured in the bike vault!): more aero, tubeless tires, more weight (1.5kg heavier!)
I did the same steady climb I use to monitor my fitness, around 1.5 km at 5% gradient.
Result: exact same avg power (on the same quarq powermeter!) for 1kmh faster avg speed. A gain of around 4% with just increasing aero and rolling efficiency!
Might be a good idea to define a ‘watt’????
What do you mean by “torque at that power”?
