In my utter ignorance I didn't realise you could go tubeless on a roadie these days, wouldn't dream of using tubes on my mtb but not sure how 23c and 100psi would be?
Is it like mtb in that some tyres work and others won't, or do you need specific tyres. does anyone have any views?
You should use specific tyres and wheels (I'm sure people have bodged it, but i wouldn't, given the higher pressures involved).
I've got tubeless 30mm Schwalbe S-ones on my [s]gravel/gnarmac/enduroad[/s] commuter bike. I like them, the lower pressures are more comfortable and I was able to carry on riding when I got a puncture a few months ago.
You should reconsider the 23c/100psi thing, for most people a wider tyre is better and lower pressures are grippier, more comfortable and no slower.
or do you need specific tyres
You need to use tubeless road tyres. A standard tyre is likely to blow off the rim.
Definitely tubeless ready tyres and official advice is only to use tubeless specific rims but I have run tubeless tyres on ordinary clinchers for a year with no difficulty. I used electrical tape and Continental sealant.
I have tubeless on my new tcr. It came set up from new. I have had 2 punctures that i know about in 2500 miles compared with 1 or 2 a month before. Both punctures have self sealed and let me finish my ride but have needed patching with tube patches when I got home. I won't go back to tubes in a hurry.
The first puncture was self inflicted too. I was experimenting with pressure to see how low I could go and found 40psi in a 25mm tyre was too low when I hit a pothole in the dark.
I run 28mm Schwalbe Ones (tubeless-ready) at 90psi on Stan's Grail rims. Previously ran non-tlr 35mm Ritchey WCS Shields, but they were constantly seeping tubeless oily stuff through pores and at the bead.

What pressure do you run yours at? I'm still trying to work it out. 50-55 seems about right for me. Still rolls nicely and feels smooth.
28 Conti at 70 front 75 rear with tubes will be going tubeless as soon as these are worn out.
I found it better to find the right tyre pressure for your weight size wheels. 100 psi? You will be faster at lower PSI try 25 you'd be surprised at the improved rolling handling.
Check the graph here as a guide http://road.cc/content/feature/180830-how-choose-your-tyre-pressure-%E2%80%94-balancing-speed-comfort-and-grip
NOTE: weight is per wheel - you should have slightly less in the front as a rule of thumb. Includes weight of bike!
If you weigh 72kg and your bike weighs 8kg, then your tyres carry a total of 80kg but it’s not evenly distributed. The rear wheel carries more of the load, usually between 55 and 65 percent.
Is it like mtb in that some tyres work and others won't
[u]Tyre choice[/u] is vital, you need a proper tubeless bead to maintain the 80-100PSI pressures. Rim choice is less critical.
I run Vittoria Corsa Speeds on tubeless and non-tubeless HED rims (85/90 PSI), and Schwalbe G-One Speed on non-tubeless Ksyriums (70/80 PSI). I've also run Schwalbe Ones on Ksyriums too, and am waiting to run Corsa G+ on my Giant tubeless rims when they are released.
A standard tyre is likely to blow off the rim.
Done this in testing with some Continental GP 4 seasons on the Ksyriums. Don't do it kids!
Yup, 28c Maxxis padrones on DT wheels, had a bit of an issue with air slowly leaking initially, they would go from 100 to around 60 psi over a few hours riding.
Eventually swapped the Gorilla tape I'd originally used for proper tubeless tape which seemed to solve it, losing less than 5 psi a week now.
Otherwise fine, easy to mount and no punctures yet, although I do realise I've now doomed myself by saying that.
Two positive benefits on the TT bike are - one can finish a race with a puncture - I rode 15 miles at about 20 PSI, and they lose air a LOT slower than latex tubes (in both clincher and tubs). I'm a big fan.
The G-Ones on Ksyriums are a match made in heaven too, easy mounting, no tape required, good profile and about 28c.
Ok cheers, didn't realise you needed rims too, that's me out at this time... 'what pump' thread next then!
didn't realise you needed rims too
You don't.
WTB Horizons on Pacenti CL25s with tape and Stan's Solution. Does that count?
It's pretty awesome. I'm running a 25c on the road bike (Schwalbe G-one TL-easy) at around 80psi.
Also got 32c Schwalbe Tl-easy on my CX/commuter bike. Had a few punctures, so far just pumped them up. That's just a bog-standard Mavic rim with duck tape.
Me too - hutchinson secteur 28s at the moment but have tried a few brands
I'd only use tubeless tyres but have used non-ust rims with no trouble - up to about 100 psi in 25s. I tend to put ordinary (narrow) rim tape or that reinforced packing tape under the tubeless tape just in case the tubeless tape gets blown down into the spoke holes. Can't say that I've any evidence that it might but it makes me feel better.
(high pressures and thin/light tyres don't always make for easy resealing and even anchovies can "blow out" IME)
+1 for hutchunson secteur 28s; I'm running them on h plus son archetype rims with stan's cx tape and solution.
Am going to reduce pressure from current 80psi - probably at 60 to see what difference it makes
I'm running Schwable s-ones on the road bike & g-ones on the cross bike - both tubeless.
I love the s-ones, run them at about 70-80 psi & think they are the best tyres i'be used in a long time.
As said before tyre choice is the critical factor less so rim choice
Schwalbe Ones on Hed Ardennes on my winter bike, and Schwalbe Pro Ones on Hed Ardennes on her summer bike. Both 23mm wide, but as the rims are 25mm wide the tyres get a nice wide profile and high air volume.
Certainly not 100psi, probably 70psi for her, 80psi for me. No issues so far and all have gone up with a track pump.
Rode the G One Speeds for three hours in driving rain last night. Deliberately lowered the pressures to 65/70. And they really are a fantastic riding tyre. Wet weather handling was awesome, never felt the least bit slippy.
Not a race tyre, but on standard 19mm Ksyrium rims, they are light enough and ride well enough to be my favourite wheelset for general riding. Can't recommend them enough. And yes they go up with a track pump.
Schwalbe S ones in 30mm on both Pacenti CL25's and SL25's.
Both great. I don't like to go to low as you do feel the drag. There is enough comfort on the road anyway with 30's so I run about 75psi. I'm 13 stone
I've used two tubeless road tyres so far, on Light Bicycle 21mm internal rims:
- Specialized S Works Tubeless Turbos at 26mm: went up with a track pump very easily, but I felt were on the fragile side, despite not being the lightest tubeless tyres around. Other than that, performed very nicely.
- Schwalbe Pro Ones at 25mm - took an airshot to get them on (Schwalbe always seem to be a pain to mount tubeless), and were about 50g lighter each end vs the Turbos. Again perform very well, but too early to tell on durability with only about 750km on them, but so far looking good. Probably my slight preference, despite the extra hassle of mounting them.
I'm running pressures of 65psi front and 68psi rear, and the tyres measure in at 28mm - I weigh 65kg. This is lower pressure than most seem to be running, but I'm yet to see any downsides (after about 4000km on tubeless this year), and is probably a function of the wide rims (which are the same width as one of my XC rims / Crests!) and my own weight. Fast, grippy, comfortable...
EDIT - I'm not blessed with smooth roads either - mainly Hampshire back roads, but also a few km in Wales recently including cattle grids etc.
Just set up my summer bike on tubeless last night, so will see... Bonty AW2 Hard Case Lite 28mm on DT Swiss R511DB rims (with some left over stans gunk).
If it works out I'll do the winter bike as well!
Schwalbe Pro One 23s on (non tubeless) Shamals with a layer of Gorilla tape and Caffe Latex sealant here. As the rims aren't tubeless specific they needed a compressor/CO2 blast to mount first time. I'm very impressed; light, roll well and grippy. Pressures vary from 85-110psi depending on how smooth the tarmac is!
My dad has the same tyres on DT RC38 tubeless rims and they went up with a track pump.
Been tubeless for a couple of years commuting on my Tripster. 1 puncture, fixed by the sealant in 2 years is all the reason you need!
Mavic wheels - tried a couple of types of Hutchinson, Secteur are good, now on Schwalbe S-Ones (Tubeless "Easy" - arf!) (well one of em was fairly easy, the other had to be stood on), which I'll buy again when these eventually wear out.

25c much better than 23c even if you are not going tubeless.
putting stans inside the tube is a good idea, might try that with some old tubes.
