Been looking around at a wheelset upgrade for the posh bike as it was poorly shod in the first place and the freehub is currently non functional (at the very least the spring mechanism to push the pawls into the ratchet is knackered) and my drive train has no drive.

Will stay with aluminium, but surprised by the amount of choice out there. Since the original intention was an all Italian bike, that simplifies things down a bit. I was also surprised by tubless now being a viable option. Anybody riding those for the road (or off road)? I will stay away from them due to the lack of available tyres at the moment, but just interested if people are using them and what they think.

Also surprised by 25mm now becoming popular. Anyone riding those? I am going to give them a try since I will probably lose some comfort from new stiffer wheels, but apart from about a 40g weight penalty per pair (plus the rotational weight), they seem to have no other disadvantage.

I ride 28, for comfort (back problem) and puncture resistance.  Continental.  Just changed the rear tyre for my upcoming bike holiday.  Not a single puncture in four years of light riding.  Seldom in the rain.

But I have noticed that several of the guys in my club, usually not the fastest or strongest guys, are riding on 25s.  When I first came here ten years ago, nearly everyone but one old guy were riding 23s.  I think they changed for fewer punctures, and to be able to ride safely on rough roads that occasionally occur on rides.  At a certain age, and a certain level of fitness, an extra 40 grammes makes very little difference.  But I have not actually asked why.

Wife ripped (rear) tyre not so long ago and LBS proposes 25 replacement and quotes '25 is the new 23', and then went on to say that there seemed to be a trend of 25 rear and 23 front...

What surprised me about going to 25mm from my existing 23mm was that I thought about it for comfort, but reading up it seems like rolling resistance is lower and grip is better too so it seems like there is no real penalty - with my belly 40g is irrelevant.

Gerry, not sure of the reasoning behind the split 23/25. From what I've read, I'd give consideration to go with the same on both. In general, a few of the links I thought were useful below.

FF, in the PDF, the Continental 28 comes out very well, so it's not really a compromise comfort tyre Smile

Bah .... you fashionistas .....

FF 28?  Isn't that a motorbike tire? Wink

Seriously, in such circumstances I always ask the question "what would Vincenzo do?"  23 at 100-110 psi works just fine for me. Are 25s really that more comfortable .... beyond what can be achieved with a small adjustment to psi?

Back in the day I would ride 19s Wink

Final thought and much more important than tyre width .... tan walls are a must!! Wink

*hipsterwarning* Wink

They are generally called gumwalls these days

I haven't opened Bio's links yet (in work with a serious post-festival head on) but I read a long report a while ago about better rolling resistance on 25s.  However, there is a problem removing a fully inflated 25 if you are transporting frame and wheels separately for racing/touring.  In the event of a p**cture that problem sadly goes away...

An Italophile calling people fashionistas. On a Pot / Kettle / Blackness scenario scale of 1 to 10, that's about a 28. With knobly bits too Wink

You're light enough to get away with reducing the PSI - not so simple for me Smile I think I've read enough positive press to be interested to give them a go seeing as they're basically a consumable item and half of the pro peloton is using them. If they don't work out they'll go on the winter bike, and it's back to the misery of 23s and Rule 5 Wink

So I guess no one is riding tubless clinchers then?

Even if none of us is riding tubeless clinchers, I would love to find out from someone what they are like.  I assume they are awful to ride, but that is purely a simply a prejudice, plus some vague memories of reviews of tubeless tyres many years ago.  They must have got better.  Is there a market?

As far as 28 being motorcycle tyres, its true.  I remember once on a lcub ride some years ago, we somehow ended up riding on a rather badly or not at all paved road through some vines.  Not sure if it was a mistake or part of the route, but I was supremely confident and fearless.  Others looked scared.  I also ride on any cycle path with alacrity.  People with 23s don't.  But they are fat buggers, for sure.

I have to tell you that when I first came to France, and first road my Roberts stretched out touring bike with 32s on a club ride, there were lots of questions.  Not least since none of them had ever heard of a Roberts frame and "Robert" is tits in French.

If Vicenzo were my age, and with my physical defects, he would absolutely certainly ride 23s.  He SHOULD ride 28, but he would not.  I have also been experimenting with tyre pressure.  I find the ride is total bliss with lower pressure, but I try to keep it up to a minimally decent level.  I swear that cornering is better too, but I never take my machine to the limit anyway.

And the Brooks saddle is also nigh onto perfect, although it does weigh in a 500 grams or whatever.  Comfort, within the limits of the basic foolishness of the diamond frame road bike position.

i was riding a clincher/tub hybrid last year for a bout a month... LBS recommended they would be puncture proof. I did both front and rear in the same pothole in the first week of riding them. The other off-putting nature of them was the noise.. a general whirrrring a bit like having a disc wheel but from the tyre choice.

Went back to pure clinchers + inner tube after that.
Much quieter and more easier to maintain on SK roads, where potholes and crazy tarmac is very popular.

Even with latex sealant? I expected them to be better than that so interesting to hear your experience. Were they any nice to ride leaving aside the noise?

I noticed that Parlee is making their latest model so it can handle up  to 28s.  apparently they think more people, including Parlee buyers are buying fatter tyres.

they appeared faster (less effort for speed?), and downhill was a breeze... uphill i felt a bit more weight/less acceleration. I could get them up +10 PSI.. so was quite a "hard" ride, comfort wise, compared to pure clinchers.

i've punctured also rear clincher on the same descent where the hybrids got front/rear double blow out.. but i was surprised too.. the reason for choosing them was meant to be the puncture resistance.

The sealant was in the tyre, but it didn't pump back up.. both front and back had quite large pinch flats...

i walked to the next village and caught a tram back to town. I guess one advantage of the hybrid is like a clincher, you can simply remove the tyre/tube combo and put on a new one. The downside to that is - it costs more money to replace as the hybrid is like buying a tyre/inner tube every time you get  a flat.

I ride cheap Vittoria tubs on my fixed and just ride home with a flat if need be.  Cheaper than a decent tyre and a better ride than a cheap/heavy tyre IMO.

Actually I am just curious, even though this is a slightly stupid question.  Have you ever in your life ridden a decent bike with highest quality 28s?  I sort of assume you have, but maybe you have not.  If not, I suggest you have a go one day.  Maybe 25s, so the shock is not too much.   Laughing

Is it still possible to find a 28 x 1 1/8 rim?

Sorry, mistyped should have been 27 x 1 1/8
