Road Bike Tyres

[Jase619]

The pillar of all knowledge. Like the Sun newspaper.

 

If GCN says it it must be true. Never mind they are in the entertainment business and their only objective is to get mainstream media positions.

 

So, as their main business is entertainment, they can't possibly be talking about facts? Or have any truth in the words they say?

 

For a beginner, that channel is filled with useful tips and insights into the sport.

 

Also a safe way of finding out things when you are to afraid to come here and get flamed by the more experienced riders. . .  Generally with the sentiments of "use the search function" or "you have to figure it out yourself"

 

Happy Friday peeps

So are you just going to troll everyones views and comments on topics or are you going to make a positive contribution to the subject being discussed?

Only the incorrect views. Not the correct views.

 

I doubt you'd recognise a positive contribution. And I make plenty. But when confronted with a "28c has lower rolling resistance than a 23c" bland statement without backup references which are freely available, then I'm unlikely to do the searches for you.

 

Now move along and do some reading so you can become informed before posting silly "troll" accusations.

 

Edit: spelling

Tubeless, tubular or tube?

Pressure?

Etc....

 

Perfect Friday thread, bring on the weekend

I did say except for one tyre. Try find another example.

 

I for one do not use GP4000S.

 

AND the Schwalbe Pro One tubeless is lower then all three of the brand you quoted?

 

So who has the facts right?

 

 

I am not sure what relevance is of introducing the Schwalbe Pro One tubeless to the matter, but I don't find an all other things being equal comparison of tire widths that contradict the findings posted above.

 

Participate in the debate and provide the links.

I need to replace the tyres on my roadbike. I have noticed that there are now different sizes 23c and 25c. What I also noticed sometimes is that the 25c is somewhat cheaper than the 23c.

 

Question what is the benefit of a 25 over a 23?

 

Thanks

 

i think the OP's question was about width.  Not brands, tubeless, clincher etc.

 

why don't we just start debating 26ers while we're at it?

[jcza]

Just get the 25s, thank me later

Disc Brakes anyone?

Kevlar shoes.

No. If you can't find this basic info yourself you are beyond my help.

 

I provided some evidence for my statements and personal experience and views you have provided none. Should I start collecting your information for you as well? And you "contribute"? OK.

 

Only the incorrect views. Not the correct views.

I recognise plenty of positive contributions but you sir have not contributed... not really... you just walked in with your flamethrower without contributing positively to this thread other than "bollocks" is how you put it - Thus now to be clear your statements are your opinion only without any proof of the fact - your opinion is noted as everyone else's is.

 

I also did not make a blanket statement about ALL 28c over ALL 23c as you incorrectly quoted me and have made your own blanket statement about. let me refresh your memory:

 

"the worst part is... they now say 28c is even better - especially if you are heavier than average. (which most of us SA gents are)"

 

Yes there has been some tests that have had these results I have spoken about and I have provided some relevance with regards to the sizing and rider weight even.  SO "bollocks" to your statement there

 

I am very well read and do plenty of research and testing of my own as well as I don't blindly believe everything I read or ignorantly disbelieve everything. But it seems you haven't. So please - I am happy to contribute to any forum with my opinion and share the information I have found and will continue to do so while I am sure you will continue to troll without contributing any relevant information I just wished you'd do it somewhere else.

 

It's not nice nobody likes trolls.

 

- Edit: I apologize for the feeding... but it's Friday!

Despite all the handbag swinging, the answer is that for the same roadbike tire, the wider one would have lower rolling resistance at the same pressure.

 

Due to its greater volume you can run it at lower pressures giving greater comfort.

 

But, at the lower pressure it would lose some of the rolling resistance benefit.

 

However , the wider one would have greater wind resistance and greater weight.

 

So, all in all an exact science but in the absence of anyone plotting the optimum balance between rolling resistance, rotating mass and drag at all weights and road surfaces, nobody on the hub really knows.

 

But the trend, even amongs pros is to go wider that 23c.

 

Anecdotally, I have been riding nothing narrower than 25c on the road for 7 years now although I have experimented with 23 and 28.

 

Go for the 25c. You are very,very unlikely to be making a mistake.

And of course there is the topic of rougher road surfaces.

A narrower tyre at higher pressure is generally going to be faster on a billiard table smooth surface but as soon as the surface becomes rougher the wider lower pressure tyre is going to win due to the whole conforming to the imperfections of the road surface story. The less up and down movement created by a bumpy surface, the less momentum is robbed from forward motion.

 

This is of course all in my humble opinion.

[Pall Catt]

Also worth considering - a previously undocumented side effect of riding 23c, as Carbon 29er has volunteered to demonstrate here, is that it evidently could give you a really terrible attitude and grossly exaggerated sense of self-importance. Which generally isn't really good for anything unless you're desperately trying to convince yourself that your opinion is the only one that matters and that people who find research to the contrary of said opinion are stupid. It certainly seems to help for that.

 

In other words, if you want to go through life being a bit of a prick but don't really want that to eat at your conscience, ride 23c. For anything else, ride 25c.

[Pure Savage]

If 23c were faster, the pros would be using them... don't tell me sky with all their marginal gains wouldn't run the fastest tyre.

We wouldn't know, as I'm sure their truck was broken into and their tyre data was stolen too....

Hehehe

See what you did there
