Strada Biancha HTLTU [Tubeless Tubulars] land

[robt57]

Naked XTR CX Tubular NIB wheelset appropriated here needed sneakers. So I ordered up some 30mm tubeless HTLTU tubulars as planned. Challenge Strada Bianca from Sigma @ 82.00 each.

Tires landed faster from UK that I am getting State Side deliveries, like the Mastik for example. ;)

Prelim report: Stretchy poo, wait for glue..

Starting life at 30mm exactly @ 80 PSI for the relaxing exercise.

The initial loose stretch air up they got fat enough I started to get concerned. Way rusty with sew-ups though, forget a lot of past hands on frankly.

Very nice and round. All 3 tire purchased just under 400 grams each. The 36mm version although tempting would not fit my Helix disc, and the weights I saw on the net frankly sacred me a bit. ;)

So the 30mm Alpine JB w/Latex tubes coming off and these with sealant are right at a wash tire weight wise on paper.

The 30mm alloy tubeless clincher wheels that are coming off are 750 grams heavier, just wheels. [Lynskey Base Visions]

These are 2128 grams as pictured before sealant/glue.

Expect to run them 65/75 on pave, and will see how they behave on loose surface -20 PSI each maybe? I am sitting at 200lb personally/currently for prospective.

Don't recall ever having tires the labels were 180^ from the valve, just an observation.

Comments and/or suggestions welcome.

Ooooooh aahhhhhhhh!

I hope you have good luck with them.

Not as much as I do. ;) Only one way to know.

[RacerJRP]

Excellent. Happy these wheels are finally going to see some use!

[Imaking20]

They look dope but damn are they heavy! Glad I went a slightly different direction for 30s :D

Which direction was that?

I have the Alpine JBs, 28mm GP4k that fat out to 31mm but get cut if I get too adventurous, And a stash of Pro4 Service Course that don't cut as easy as the GP4Ks, weight even less and fat out to 29+. So all 30s in my book. They Pro4s don't seem to roll nearly as well as the Contis, but maybe better than the JB, maybe.


I'll add this re: Stradas. Last tubulars I got was 6-7 years back. 6 Clement factory made from Yellow Jersey, The Stradas appear very much straight and beautifully round comparatively.

I feel lucky I got them for what you let them go for, thanks BTW.

Well compared to what really? Soma or Challenge Open Clincher w/extra light casings? 30mm tube even latex is 80 grams. And stretching a smaller latex tube is a fools errand, just ask this fool that has tried it. ;)

Supple Vitesse SL 33mm=250 grams+ 80 tube, 70 grams less for a lot less durable rolling setup. EX heavier tire +40 grams might be a fairer durability comparison.

Apples/oranges stuff kinda...


The Strada Open 30mm is 350 grams, as is my Alpine JBs, both need tube. But to the sturdier side VS ExLite stuff more material suggests.

Strada TL in 30mm is 305 advertised, bet it is heavier by a little, add sealant. I may get some to A/B to the tubies on some light-ish clincher wheels. None on my disc clinchers come close to these XTR 1350 gram hoops. Being a Clyde [albeit just] I am weary of 24 spoke disc wheels with less than 30mm rims honestly. Back to the Visions that are quite heavy, but strong enough to do some off piste that is not smooth as glass...

He!!, the pave here is not smooth as glass...


That is all just words, I wanna roll these, glue is in the mail. ;)

65/75??? u arent afraid to just dent the rim with such a pressure? Find it way too low IMO specially for the front one.

75 is max pressure on sidewall. So too gnarly terrain probably risky. And the rim is carbon, so crack/ruin not dent like alloy.


For me @ 200 lb., 47x650b or 42-45x700 be chosen for gnarly use. Or if too gnarly 2.2x650b on my Gary...

[wallymann]

is there a minimum rim-width for these?

[robt57]

is there a minimum rim-width for these?


Dunno, but the base tape stick past the 26.4 XTR rim 2mm or so each side. If glued onto a 19 old school rim be a lot of tape hanging out.

I did not see a limit will all the googling I did getting up to this point, which was a lot.

Just saw this on the Trek site for the 36mm, Could just be generic cut/paste crape...

Specifications:

Size: 700
Tyre Width: 36 mm
Internal Rim Width: 17-23 mm

They sit on these XTR rims like a glove I can say.

[DfCas]

Have you checked the pressure to see how much they are bleeding off? Could be some stretching going on too.

I pumped them to 80 PSI and sat for about 30 hours before I figure that 75 is max. DUH, They were still very hard, I bled off a bunch. No sealant in yet either. My latex tubes in clinchers would have been softer than I'd want to ride them 30 hours later.

[ultraman6970]

Now that i see them better i think you will be ok, those things are really tall... do they have 23s and 25s of those?

The 25s appear to be called Just Strada, Bianca is 30 or 36.
Their Roubaix is the 27mm, and like that.

Well compared to what really?

Other 30mm tubulars.

More specifically? Who else does a 30mm Tubular that is gravel slated? And how much does it weigh. So we can have actual data point to A/B. Else what are we bothering to discuss exactly??

I am guessing you saw the smaller tire data perhaps and not the 30.

The Strada is advertised lighter than I weighed it. Betting same case for this tire.

Let's say that is 370 true. 27 grams more for the Strada.
I'd like to see the initial thread thickness for both outta curiosity.

I didn't see any data. Just offering a 30mm alternative for discussion.

I'd rather pull out my fingernails than discuss tire weight. So y'all have at it.

LOL, I mistakenly thought I was in reply to another message.

FWIW, I went thru way too many Vitt Pave$ way too fast and probably won't buy Vitta in the foreseeable future. Although I was 30+ lb heavier then. Hope these Strada don't wear like that...

[Pastashop]

I mounted a set of the "36 mm" on yer classic Reflex rims –*about 3-4 mm of base tape showing on either side, running pretty straight, tire puffed out to about 37 mm width. No sealant. They do bleed off air, a bit less than your typical latex-tubed tire. About 80 miles of mixed riding, mostly dirt and gravel, on them so far. Comfy ride. More comfortable than Vittoria XNs, but obviously running at lower pressure (40 psi?..) that would be expected. Recommended!

[merckx]

My 30mm Corsa Control tubs are 370g. No one will miss a cafe stop because of 30 grams. Keep the reports coming. They look interesting.

[skijoring]

Did you ride the set up yet? Good looking wheels, I hope you progressed past the minutiae/weight/etc.

My Mastik is in the mail, ahem...

I stopped local LBS and would need too many tubes @ 7.00 ea with fresh tires/rims. 250g can inbound.

[robt57]

For those curious, started gluing them up yesterday. Finished up today @ noon and did a no lean ride on my street. Got home from a 35mm carbon wheel 28mm clincher latex tubes ride, cooked, ate, showered.. yada.

8 hours after noon air up, rode again in my sub div. #Gah!

Tomorrow going to roll a serious ride.

But prelim review: @ 60 PSI my Helix Disc feels like my Look 585 with 27 Paves w/latex tubes @ 75 PSI. It is really an absorbing chatter effect big time.

Got a mini plug kit, and will ride without a spare with the mini plug kit and a 2oz bottle of Stans.

I got there finally. Been planning tuneless tubular for a while.

:banana:

Observations VS last 17-19mm rim with 22mm tubular glue/mount 8-9 years ago.

1) 26.4mm wide rim much easier to brush on Mastik by a lot.
2) 30mm tire with way wider base tape, same.

3) Way more surface area, good for grip. Not so good for repositioning. Front was a bear, I let last coat set too dry before mount. So I put another thin layer to wet rear base tape and that went faster and easier.

There you go.

[skijoring]

Don't roll through downtown; lotsa broken glass. It's Marathon/Gatorskin country only down there. :)

Now that CV-19 infection rates are climbing like the side of Mt Hood, I won't be headed towards PDX from my approx. 20 miles out. Boonies for me for the foreseeable future.

[robt57]

Another observation.

I have chased fatties for a while. Have done 47-8x650b, Soma 38mm supple vitesse/Latex tubes. Been running latex in 27,28, 30-32.

My Strong All Road has 35mm Hutchinson Override tubeless FWIW. Another set of wheels with Nano 40s for off piste.

Some of the best feel has been the Vittoria Paves with Latex tubes. Ride as well as my old tubulars. But a 25-27mm open Vit compared to a 22mm butyl tube sewup, it should ride better even if just for way lower pressure. I am sure Open CX Vitts would ride even better, but at my weight I'd go thru them way too fast.

These Stradas on a fairly stiff/stout riding bike exceed every thing I have ridden to date in the feel dept. Granted I have 2 miles on them until I get my ars out today.

I have said in every Look 585 thread that bike does not need latex or bigger than a 25 open quality riding tire to ride/glide up there with the best in my decades of rolling.

I am glad I was limited to the 30 Strada fit wise on the Helix, else I surely would have got greedy and got the 36s.

Just like my 585 does not need bigger tires for ride quality, these 30 Strada feel plenty cushy enough that the weight of the 36 not worth it for my use, mostly pave. Now for a lot of loose, bigger is always better. But I think my point s made.

When Challenge goes tubeless on the 27mm Roubaix tubular tires, I may go down the dark side further, contingent on the reality of rolling these.

In my minds eye, a Bianchi CV or Look 585 with 27mm Roubaix toobies probably be as good as it gets...

Ah got it; you live outside of town somewhere.

[robt57]

Yesditty, I spent 3.5 hours out on the Helix adorned with these toobies @ 70 PSI. I felt like I could ride all day.

I am afraid I am spoiling my self terribly to accept less ride comfort on about anything else. ;)


Setting up my Strong All road with 38mm Soma Supple Vits and Latex tubes on the carbon wheels I pulled from the lynsk to put the sewups.

I doubt even that will be as orgasmic as the 30mm toobies.

Thanks for taking us along on the journey with your magic treads. Very cool. :beer:
