'Upgrading' to skinny tyres pointless for London commuting

An image for all occasions, just in case anyone needs it.

You can shut up.

Also...

Have you considered not swallowing?

I imagine mdcc_tester leaning over to GAG2 – with one arm on the bar when he says this.

On top of that, pressure varies with temperature, say tyre was pumped up with cold air from your cellar then let the wheels stand out in a hot sunny day - BAM.

There used to be a time I'd keep an eye on having the right pressure according to my weight and so forth. But since there is a general gradual loss of air and varying pressure...
who cares?
Just go max, sorted.

CSB WARNING

Couple of years ago in May we were on a riding holiday, and that day we did a bit of climbing.

I finished both my water bottles off on the way up, capped them and didn't think anymore of it.

Got to the bottom on the other side, and both water bottles had been crushed by the ambient air pressure- they were barely staying in the cages anymore.

Did make me think how many (relative) PSI the tyres had put up with at the summit, with the lower air pressure at the altitude we reached.

Thread synopsis please?

Tyre too hard for daily commutes, having been told by evans helper that skinny tyres are faster innit.

Customer has realised maybe not the whole story.

N*** and A*** go bonkers.

Fox ends up punning Morrisey.

Hilarity ensues.

Thread synopsis please?

The balance between weight, aerodynamic drag and rolling resistance should be optimised by rigorous analysis, not superstition, tradition or old wives' tales.

Not this^

Totally missed the point.

My house mates a Cat3 rider, I’m an unfit beer drinking slob in comparison.

It takes him 35 mins to get to work on a carbon loaded with Dura Ace and skiny tires, It takes me 35 mins to do the same journey on my shity old fixed.

We have both tried different routes, shorter with more traffic lights, longer but with less lights. They all take the same amount of time.

Simple conclusion. The bike (and the rider) makes little difference on a commute (But i reckon if we did 3 laps of Richmond park he’d beat me by 30+ mins)

Repped.

I ride a 28 on the front and a 25 on the rear and I pump the fuck out of them... Pretty sure its all wrong but it's better than the train.

I have 1.6" slicks on my mtb at 80psi, seems to roll faster than most other bikes on the road (always have to brake when freewheeling downhill behind someone).

...Or it's because you're drafting someone?

naw, heavier tyres make you roll faster down hills.

Which tyres skid the longest?

23's @ 100psi.

Deep rims and high flanges.

Old Skooling it likes it's '07 all over again. It's how i motherfuckin roll.

Which tyres skid the longest?

Time or distance?

all else being equal.

This thread is solid fucking gold.

Great job everyone.

No, you're a cunt

was pumped up with cold air from your cellar then BAM.

First rule about my basement : Nobody talks about my basement

Nobody has ever come out alive from basement except me...

When I was a kid my parents used to tell me, "Emo, don't go near the cellar door!"
One day when they were away, I went up to the cellar door. And I pushed it and walked through and saw strange, wonderful things, things I had never seen before, like... trees. Grass. Flowers. The sun...

Needed an excuse for popping tyres after they leave the cellar..

...Or it's because you're drafting someone?

Not sure if serious...
I'll bite.
Seems unlikely that I am freewheeling down famous London's famous slight inclines at a speed where drafting would make a difference... Plus I'm generally braking to stay out of that kind of close zone.

What's heavy for tyres?

Marathon Plus.

Their 25c weight a whopping 590g.

Hah. My mtb tyres are 500g!
