'Upgrading' to skinny tyres pointless for London commuting

Well I bit the bullet and tried 25s on front and back today (after my 23 gator had enough) for my weight 87kg they're a nice change and actually felt a better at high speeds and even at a lower psi. Only problem I can see being the clearance between front brake and tire is now very small and any wet riding debris may cause a build-up on the forks but I’ll deal with that when needed.

I could never ride 23s... Ive been trying to go bigger than 25s actually. But this was before I knew that 19mm was to small. Im waiting to burn thru a lot of 19mm rims.

Wait, you have 19mm tyres because you have a 19mm rims?

^^You can run 28s on 19mm rims, no problem.

not with my fat arse. I have lost so many innertubes to them just simply exploding because the tyre wouldnt sit on the rim

You're doing it wrong.

And are fat

I was thinking, 10% wider isn't much really, but I forgot that you'll actually have about 20% more air in a 25mm tyre (Pi squared R).

I'd like to try like-for-like, so maybe my 23mm GP4000S tyres versus the wider equivalent.

Remeber the volume of air is also affected by the rim width. These new rims in pro racing are as wider than open pros and plenty wider than a 19mm rim.

you tried to fight with a bus, could not tighten the cog and lockring properly and now you couldn't get the tyres to sit properly?

you need life training Iain.

And are fat

Big boned.

Fat boned.

You're doing it wrong.

You shouldn't be throwing stones, Ed.

we're doing it wrong.

fixed.

I’ve decided I don’t like 23’s any more after slipping on mine on some road debris the other night. 25’s all the way from now on (in London anyway), I can’t be doing with ANOTHER thing that makes me feel anxious while I’m riding.

^ I washed out recently on a wet corner due to lack of traction up front. That's made me wonder about running larger tyres at lower PSI. I already run my 23s at around 80/60 though.

(I ran them at 120/100 in the dry).

It wasn't even wet when I slipped. I had the tires pumped up pretty high and there just seems to be SO MUCH CRAP on the roads at the moment.

^^there are other things to try, like changing position (either permanently or through body English whilst cornering) to get more weight over the front wheel; different braking technique; ride more slowly in dubious conditions; and so on.

More weight on the front wheel?

Do not want.

Weight on the outside drop (unweighting the inside) is good though.

Yes, the weight's 'suspended' from the outside drop, but you still get some benefit from a slight overall shift of rider weight towards the front, to keep the wheel planted. How a bike corners is a great way to get your stem length / reach dialled in. When you get it long enough, suddenly you can confidently enter curves carrying quite a bit more speed.

Bike handling is very much like making love to a beautiful woman.

Quick?

Dirty?
