Vittoria Randonneur

depends what you skid on and how long your skids are.

i almost never skid these days* unless its just a quickie and i need a sharp adjustment of speed besides that its pretty much just the E brake

*compared to when i would only stop by skidding

EDIT forgot to make my point....

i really like my rando combined with a schwalbe ultremo on the front its a nice balance of good traction and high speed

Max, do you skid at every chance? not even resisting the pedal a little to slow down?

.................and finally popped it's raw anus this morning near Waterloo on the 3rd of July...............

haha! nice one Ed. brilliant

Max, do you skid at every chance? not even resisting the pedal a little to slow down?

i admit i used to once upon a time, but no, not really anymore. it depends on how i'm feeling really if i feel like slowing down gradually or just caning it about and suddenly stopping with skids.

Just had to change my Continental 4 seasons tyre.

so what was it like ??

well, the semi exposed criss cross webbing on the side wall was coming off at various places around both sides of the tyre. not good, bad sign.

a 2mm hole/tear/gash exposing the tube at the tyre/sidewall interface, that was getting larger hence why i had to changed it.

and a 1mm hole down to the carcass right in the centre of the tyre tread again exposing the tube.

so after only about 1500miles and hardly no skidding, id say they were pretty poor considering the price.

Hippy might have a point, cos considering Conti 4 seasons cost a whopping £25 -£30 each ! you'd expect a little better.

Rubino pro ( +/- £18. £10 cheaper than conti 4 seasons.) is on now and ready to roll,
lets see if the myth is a reality.

I have to says that the grand prix 4 seasons tyre have a lots more grip in the wet than the standard gatorskins.

i thinks gators work better in the wet

sorry to bring this back from the dead, but.
the 28s, do they really look like a 25? 'er indoors has 35s on her commuter, i was thinking of putting 28s on this. but reading this it sounds like a 32 would be best.

anyone have any advice about this?

a 28, is about 24/25 wide. but 28 tall

mmm. so they're not being accurate with the width measurements?

mmm. so they're not being accurate with the width measurements?

they measure it by thickness I think, it's very thick to the point that you only need a 19-25c inner tube, a 28-32c inner tube is much too big to fit inside.

and at 100psi+, feel like a 23c.

and at 100psi+, feel like a 23c.

I'd say more like a 25c. 23 is pushing it... :)

mmm. so they're not being accurate with the width measurements?

depends on the rim widths doesn't it

Don't take any advice from Ed on this particular matter

^ Ha!

He's right about the above though.

right, so, i thought.
"700 x 35, i can drop to 28s on that, quick look at sheldon, yep, yep i can." then checked this thread out and the opinion is that 28s look like a 25.

i was under the impression that 700 was wheel size, 28 was width. am i, indeed, wrong?
because a 25mm tyre on a trek hybrid is going to look a bit odd.

It varies between manufacturers. It varies between models. Like some Cunti 23s were closer to 20s back in the day.

right.
so.
tyre manufacturers = cunts?

Not really. It's not exact is it? Depends on how much air you put in and the width of your rim so they're only really giving you an estiamte anyway.

Continental though, they are cunts.

right.
so.
tyre manufacturers = cunts?

"Dishonesty in Sizing

Competitive pressures have often led to inaccuracy in width measurement. Here's how it works: Suppose you are in the market for a high performance 700 x 25 tire; you might reasonably investigate catalogues and advertisements to try to find the lightest 700-25 available. If the Pepsi Tire Company and the Coke Tire Company had tires of equal quality and technology, but the Pepsi 700-25 was actually a 700-24 marked as a 25, the Pepsi tire would be lighter than the accurately-marked Coke 700-25. This would put them at a competitive advantage. In self defense, Coke would retaliate by marketing an even lighter 700-23 labeled as a 700-25.

This scenario prevailed throughout the '70's and '80's. The situation got so out-of-hand that cooler heads have prevailed, and there is a strong (but not universal) trend toward accurate width measurements."

Hence those old Contis being closer to 20mm than 23mm...

right, i may look at 32s then.

Hippy, why do you hate continental so much? have they epically let you down just at the wrong time?

those 28s are skinny aren't they?

Hippy, why do you hate continental so much? have they epically let you down just at the wrong time?

Not really. I rarely use them since they were always failing on other people's bikes.
I had a pair of their tyres a while back (fuck knows why I bought them) and they p_nct_red 4x in 400k.. I put the already cut to hell Rubinos back on and they were p_nct_re free for another 1000k.

It's a slightly irrational hatred but 1) look at the evidence - Contis DO just self-destruct at the most inopportune moments. My LBS guy loves the All Season GP4s/GP4000? or whatever they are called? but it doesn't mean I'm going to start using them. Conti would need to go a good few years without me hearing about their epic fails before I bothered.. and.. 2) it's funny, so it continues :)
