What do you think would be other marginal gains worth about 1 watt? Also, guys with power meters....... please contribute to our new survey on your power (FTP test) according to your position on the bike: fft.tips/positionform

I'm listening to the ramblings of a bike geek. it's good to find good company. I'm totally subscribing to this.

I made a number of various optimizations, the big one going from a -6 stem with 15mm of spacers to a - 17 with no spacers, and a 40cm round handlebar to 36cmm slightly aero profile handlebar. Also went from bibs and a race cut jersey to a very tight fit trisuit. Also swapped 35mm deep semi aero wheelset for a 45mm aero one. Butyl tubed GP5000s to TLR Vittoria Corsa Speed tires, lots of small changes here and there over the years. It adds up. The end result was that on one of my longer flat-ish segments which is about 50km long, with roughly the same air temperature and neutral wind, in 2019 it took me 233W average to go 33.6 km/hr. Recently I was doing a long tempo ride and averaged on the same segment 33.5 km/hr with 197W. That's a huge difference.

One What?

5:50 Thank you for your work, appreciate the posting of this info. However, front rim brakes - if you are not spinning the front wheel in the wind tunnel test, then an aero looking brakes offer less resistance. But spinning the wheel in the 25 mph range, the late Steve Hed found in his wind tunnel testing for different frame manufacturers creates so much turbulent 'dirty air', from the top of the tire spinning, it really didn't matter what the shape of the brake caliper was, so aero brakes were purely cosmetic, not truly functional. Just my 2 cents.

12:30 , thats not flo cycling, that's rotor's crank model named flow

Not sure if it's a watt, But triathletes are allowed to cover "holes" ,bolts, ect. with tape

Having a valve stem that is too long, cleat shape, aero socks, shoes, a dirty bike, having a large watch, hairy arms, i could go on

Fantastic video, as usua, Alexl! Will be putting a few of these into practice! Cheers, Vic 👍

Move computer head unit from top of bar to in-front of bar

I can save 6 watts. Sadly I have a heavy bike, but at least there's no bar tape.

Now we know how to save "wonwoh", I have just one further question...

for what is the ear smashing noise? i have to quit the vid, because i dont wanna have a heart attack too

Per Silca, aero socks gives 30 watt savings for about $30. Gotta cover basics before the expensive stuff as an amateur

Music is TOOOOOOOO loud!

8 ot of 10 implementing the 80/20% rule 20% of costs and 80% of the savings.. Just be smart when choosing in the first place though there are a lot more small gains to be had, Speedplay shoe+ aero cover/cleats Shoe covers The shoe you choose (i.e. is the shoe / all components aero or bulky) valve covers from silca etc.

can't believe you didn't include the 'penis pouch' to keep the family jewels compact and aero...depending on the rider can be up to 10 watts !

Your patreon link is not working.

Watt's Up, Doc?

Awesome . Amazing what people pay for not much gain.

Easy. Just turn down four watt by exactly three watts

Victor was 3rd

How many watts can you save by not having a power meter?

How much weight should loose an ideal rider (70kg at 250w) on a climb (ex. 8%) to save 1W??

I think you missed the biggest savings. 1 watt per donut

Check out the hobbit feet @4:38.

Taping ears back = 1 watt?

what was this flow simulator you used at 7:54?

Great tech details as always and very helpfull videos :) That is interesting cables exposed are such small amount of power lost? However more interesting is how much we can gain by throwing away bidon on flats at lets say 40kph? Some of those aero bidons looks aero fancy, but in many cases we do not need them at short TT events lets say 20km ITT, so I gues it might be more than 1W saving or maybe I'm wrong? Putting bidon back after saddle not great idea since we can loos a few seconds trying to reach this bidon, so it looks like the best option if not banned by UCI could be dring pipe to bidon hidden in bike aero frame, so that is why I'm working now on such solution...

Shit the bed Alex, you’re blowing my mind!

1w is big for me considering I have an ftp of 145

Are aero gains even taken into account without a direct head wind?

Mechanical watts? You can have all of the FFT top 10, with shitty bearings in your hubs and drive train you can minus how many watts?? The chain was touched on but hub bearings, freewheel bearings and BB bearings all take your hard earned watts too. More than you think and more than some of the industry will tell you.

Stems. Negative degree stems

What you little you gain as 1 wattage is multiplied by 100 when it comes to psychological advantages.

Did you just steal my Watts up 😕 ha ha ha ha could have asked😋

1 watt is not worth anything
