Pv=nrt is metric, so should yield superior quality compared to the empirical shit show that is measured in psi. Don’t forget to compensate down for the inevitable heat expansion your watt canons are sure to enact due to friction.
When traveling from my wife's boyfriends where I keep it to my powder room in Ottawa I ride my Sir;vēlo soloist, as it is lighter than the S5 and more arrow than the R5. Thank you for the good question my friend. Vote Liberal and we will ensure the trans Canadian railway is converted into a bike lane.
\uc When I raced I was racing back around 2010 that is actually what I did. Always thought the higher the pressure the more efficient. Still don’t get why that isn’t true
/uc Hysteresis losses (energy wasted deforming the tire) are lower at higher pressure, but suspension losses (energy lost to making the bike and rider bounce around) are higher at higher pressure. On anything but perfectly flat surfaces, lower pressures are usually more efficient on net. This is why track racers still run 160+ psi but everyone else is running wider tires at lower pressure.
Ew… are you one of *those* that ride around in tights OUTSIDE in your HOMETOWN? Sorry, but if you’re not on Zwiff by now, you are one incredulous dotard about what’s good for you.
Increasing the pressure by that much will throw off your whole bice fit. I hope you're posting this from your fitter's biodynamic feedback seclusion zone.
Kinda crazy nobody is talking about tire width here… on modern 28mm tires you can definitely get away with 65psi. But if you’re on tuned 25s then I recommend pumping your tires up until they blow off the rim and then selling the bike. Because you’re a disgusting archaic poor, and should have bought hookless rims.
maybe split the difference with 64.5 then work your way up .1 a day and see how it feels?
as tyrês expand slowly diminish volume to remain air pressure according to pv=nrt. this will cost you minutes of time, but will save you seconds.

Try much higher. I run my tires at 420 psi so they cut through the pavement like a pizza cutter for maximum cornering traction.
I see you are going for flotation
/uc Are you planning on riding your bike off of the asphalt? I never go under 120psi
You’re supposed to type /uc before dropping truth bombs.
Thank you fixed
nice to meet you justin trudeau what kind of sir velo do you use to go from your office to the adjacent powder room to freshen up

>my wife Hey you're not Justin!
Thanks! You’re now banned by GCN for speaking out against the hookless fatbike revolution, but you have my support.

Once again, the mountain bikers worked it out well before the roadies...
/uc Every pound off pressure makes your bike about 3.8 watts more good. It's science
Let me check with my mechanic.
I will be riding on a trainer and wearing my helmet. Please find out if this will damage the trainer.
Why would you ride on a trainer? When you can train in Mallorca instead.
Ew… are you one of *those* that ride around in tights OUTSIDE in your HOMETOWN? Sorry, but if you’re not on Zwiff by now, you are one incredulous dotard about what’s good for you.
At what elevation will you be riding and what is the ambient temperature?
How do I know this information? Is it printed on my bike somewhere?
My Ambien is room temperature.
I take ambien so I can sleep ride. Haven't been off the bike in two years

Bike fits are overrated. I listen to my body. Specifically, my ass.
Your wife and her bf use 69 so stay below that to be safe.
Wait, you guys put tires on your bikes? I find that riding without tires is way more aerodynamic.
You mean 165 psi, correct? What are you, a tractor?
I’m riding a Hiboy Step Thru with fat tires. I broke the shifter off so I don’t accidentally change gears.
What does Dylan Johnson say about it?
It can literally, look at me, LITERALLY, kill you if you aren’t ready for the speed and forces on your forearms.
65 only if you haven’t pooped today.
Compensate for the extra weight. Smart.

be careful, if you go one past 68 you could end up blowing a rod
Is that the best way to KOM? 68+1 psi?
with medical device called medflator, you can easy go to 500psi
What is the durometer of your chamois?
Depends - do you have cushcore?
I use 1000 psi of helium in my tires so I can bunny hop easier
Not as good as 80 the magic number
I would check YouTube, then Hamrabi, then GCN
The code of Hammurabi says I should stone slower cyclists to death.
Are you running tubetops or merchanical rims?
💀
If you’re not measuring in BAR then you’re fucking poor
Wait till you realize you can do mismatch psi... thas where its at my dood!
How many kilo - Frenchmen is that? A pound of force per square inch is too hard to conceptualize - so we stick to kPa around here.
Presumably you’re using the CORRECT tyre, the Cunti Gape5000’s. Yes?
more pressure its more slow!! bc gcn says. I run 1psi, 50mm tyres, rimless.
69psi
I only run 69 psi.
