Yup, grolby, it's mostly a matter of taste, not what you need for a particular situation. As a teenager, I was into road bikes. There were no BMX or mountain bikes yet, anyway. I rode the narrowest tires available sometimes, and at other times, I rode tubulars, which are normally very narrow. Now I'm older and often carry stuff, and for those two reasons, I prefer 28's to 32's, but I still like to jump on my old racing bike (with narrow tires) from time to time.

I do ride some rough trails on my road bikes. I still haven't gotten around to getting a mountain bike.

I also used those Specialized Armadillo tires on a century ride and hated them. I got them specifically for their puncture resistance and got three flats that day! I eventually called the SAG wagon because I had ran out of patches and tubes!


Three flats in one day on Armadillos? Hey, what lottery numbers do you use? What type of flats were they?

They were all punctures from glass. I'd used them before on my MTB for years without any issues. I may have just gotten a bad tire.

It sounds like you have other problems with flats, however. I live in a land of where goat heads...one of Asia's gifts to the southwestern US:rolleyes:... are a problem added to normal road debris and I experience no higher flat rate using 23mm tires than 32mm, 35mm or 53mm tires. True, I do armor my tires with belts to resist the goat heads but I don't run them on my bike with the 23mm tires. I don't run the Armadillos but others out here swear by them.

Flats from sharp objects are difficult to avoid but flats caused by impacts are much easier to avoid. FBinNY's post is a good post on how to avoid flats from potholes (See, I don't just find fault, FB).

8 bars makes it even worse. I have never had a pinch flat - can't remember. But there are lots of small pieces of broken stone and glass. 1 cm or less in diameter. Those find their way into the tyre if it's at a pressure over 6 bars, while at pressures below that, they just don't stick somehow.

My other problem with 23s and speed is harsher ride. Switching to 28s on the road bike in the spring and will see if it's better.

I run 100 psi front and 120 psi rear and I ride through glass from bottles and car glass and haven't had any problems on over 5000 miles. In my opinion, the rubber used in gatorskins is very hard and bits of glass don't get imbedded in the rubber.

If the wider tire rolls faster at the same pressure, then at some lower pressure for the wider tire the two tires will be the same. I'd rather ride a 28 at 90 than a 23 at 120 on a commute over typical city streets.

Yep. If everyone did the same thing, it would be booorinnnng.

+99

This applies to 99% (or more) of the "you need to do it this way" posts.

That's the impression I have with the Armadillos as well. I can wipe the tire down after several miles of unideal roads and the thing still looks almost new, with no bits and pieces embedded. Can't say the same thing about the softer rubber tires on my other bikes.

Old thread I know - I'm wondering what saddle you've got on that Cannondale, is it a brooks swift? - I'm picking up a new sport bike but am a little hesitant putting the big b17 from my touring bike on it, I was playing with the idea of a different brooks. If it is, how do you find it?

noglider 07-12-14 12:18 AM

The B17 is a fantastic saddle, suitable for many bikes.

TransitBiker 07-12-14 04:01 AM

Yea, to minimize impact on wheels simply lift off seat, and then barely have any weight on handlebars but still secure for steering & staying on. A few hard knocks and you eventually figure out what you & your machine can do best as a combination. Perhaps upping the tire width a bit would help too. How much upping, well you gotta experiment i guess.

I have nothing but buckets full of thanks for noglider and FB for freeing me from the max pressure mentality that is still so apparently prevalent, from reading this thread.

I follow the recommended pressures according to Michelin for tire size and bike/rider weight, I figure that they've forgotten a pooppotfull more about tires than 99.99% of forum posters will ever even believe due to individual ignorance (even though an individual poster may disagree).

23f/25r at pressures so low I should have nothing but problems, if I followed forum advice. Paying attention to a tire manufacturer's recommendations I have yet to have encountered the first trouble.

And have enjoyed a comfortable ride the whole way.

rumrunn6 07-12-14 08:50 AM

ouch! I like t stay on rides I know and usually ride the same routes. I have a handful that I do throughout the year. two in particular. it helps when there is some predictability

Thanks on the seat, it is a Chinese deal! Cost about $73 shipped, I liked it because it has copper rivets and goes along with the black and gold on my Black Lightning. I have a white one on my 85 Raleigh Prestige.

I think this is the one,

EDIT correction, it is THIS ONE, that I got, they might be the same

Great, thanks for the info and the link!

I find 35 c tires do very well on rough roads. What I lose in speed I gain in comfort. I feel less fatigued and more refreshed at the end of a ride.

42 c would be great pothole smasher tires. I'd reserve skinny tires for perfect roads and any place where the streets are like a road to heaven.

That's rarely true in the real world. Wider tires rule!

+1 to FBinNY's post. If you "ride light", 23-25 mm is fine for urban riding.

a flexible high tpi tire is far less likely to blow out than the brittle and hard tire many commuters run.

max pressure depends on the tire. i sometimes commute on tufo clinchers at 160 psi. these tires are amazingly grippy and supple! if they were not so bloody expensive i'd use them on all my bikes.
