Good time to build some wheels, [lightbicyle.com]

[robt57]

Built up a new Helix Pro Disc w/ENVE fork.

Almost sent it back due to income interruption.. But hope knowing I'd be sorry later if I did swaying my opinion to 'not send back' does not come back to bite me, yada.

But had to stop spending going forward for now. So my last built XTR/Pacenti HD gravel wheels went on for now. But lighter in the cards as soon as I can trade for or get parts together to build.

I plan to go tubeless tubular, now that they actually exist. ;) Shooting for low profile low rotational mass et al.

>Who has what to say about these, or light-bicycle offerings?

So the tire choice is driving the rim choice, I'd even like wide for the fatter tubulars planned: Strada Bianca 30mm so far. I only have old school tubular experience, narrow rims and skinny tires from the way back machine..

Non braking surface version perhaps...

25mm deep tubular super light 25mm wide rims 700C with basalt braking surface.

I'll stick a pic of the bike so far. May see some gravel use, but planned purpose is a go fast outback crud pave machine.

Sitting with 32s now, rims are 21cx622. Back just making that tire tight on the chain stays.

If I like it a lot, a SR Ti/Cult will go on. Just my test groupo on there for now. And a test of wolf road link with a SS RD, the 40t platter was already on the wheel, not staying. FD adjusted only to allow trim on the little ring to avoid tearing off stuff for test rides.

Have built a few sets of Light-Bicycle. All were very nice — nicer, in fact, than mainstream brand carbon.

I have to do some research to understand what a tubeless tubular is. does this mean there is no pressure boundary separate material between the base tape and the tire itself? so the pressure boundary becomes the base tape? if that's the case, i could see them having an advantage of being able to be repaired easier with tubeless plugs.

Yup, instead of a butyl or latex tube being sewn in for the air retention a latex layer is bonded or fused together with the casing. So the casing is still bonded to the rim with tape or glue, and the rubber tread is still on the other side, but in case a puncture occurs you can seal the rubber tread and casing up with a plug instead of having to try to patch the tube or mount an entire new tubular.

Seems like an ideal solution for getting the best out of mixed-conditions gravel riding as it will provide tons of comfort and grip with zero risk of pinch flats. And the plugs have gotten so good now it's worth the switch to tubeless just for the ease of a roadside fix.

got it.

i also like the idea of being able to add sealant to the tubular directly and not have it swooshing around against the rim as with a tubeless setup. much cleaner.

depending on pricing and availability, i'm a buyer!

They're actually not too badly priced at $100 retail, which is about what a good tubular and latex tube costs.

Hopefully they perform better than their previous foray into tubeless and open tubulars, of which I've heard nothing but bad things about.

[robt57]

Once some of us catch on, and scoop up all the good used tubular wheels that go for low price per purpose VS clinchers. ;)

In my minds eye, I am drooling with anticipation of a 30mm tubbie @ 70-75 PSI and how that is going to feel and conform to surface in bumpy turns at speed...

[DfCas]

the more I think about it, the more I think I might try tubeless tubular. The idea of replacing a spoke sounds like fun thi.

What tire manufacturers are in the game ?

[robt57]

I just replaced 6 spokes in my XXX carbons without even deflating. ;) Almost lost one nipple, close. :help:

Not loose so much, I'd have known where it was.

Now my Pacenti wheels in above pic have a loose nip in the rim. Used Fortezza rims, the infracting rattler must have been jammed in there and shaken loose one I used the rim in those wheels. I keep count during builds, not one I lost, rather one I found, albeit to late.

And of course I taped it all up for future tubeless use even though set up with tube so far. Gonna try and get it out of the valve hole now that it is semi liberated....

[robt57]

Now that I got some of you co-drooling....

Question [one] is: Just carry a plug kit, or still carry a pre-glued tire along with??

[DfCas]

Plug kit only.

[robt57]

Plug kit only.

At least I did not have to be the first one to suggest it. :no:

[robt57]

OK, not a nipple making the rattle.

This is a first for me. I tape with kapton tape only for years now, and tubeless or not follow up with one layer of Pacenti Blue tape because I had a lot of it for a while now.

The noise was the piece of kapton that bunched up when I x-acto cut the valve hole thru the tape that had fallen in.

How that tiny little kapton origami pterodactyl could make that rattle is quite a surprise to me...

I could hook you up with a set or Boyd tubular disc wheels. Rim profile is very similar to the LB rims you posted. I also have 3 new 30mm Strada Bianca tubs for ya to use with them.:banana:

Only interested in the tubeless tubular, this will be a future purchase once the CV19 stops effecting out cash flow.

New here, but I'm doing some research on LB wheels and I'm curious on your thoughts.

Have you built up any of the Falcon Pro wheels with the "direct-from-mold" finish?

I'm trying to decide whether that finish is worth the extra money.

After reading up and looking at the Challenge site, just verifying that the tubeless tubulars just mount to a standard tubular rim? And the handmade tubeless clinchers to a standard tubeless clincher rim?

Good concept. I'm still carrying baggage about Challenge tubular quality issues (Strada 25s that had poor sidewalls and tread came off) so it will take me a while to think about actually trying these. Much prefer to have others be the testers:rolleyes:

[dddd]

Interesting the inside V-shape of the rim, seems designed to handle a wider range of tire widths.

[oldpotatoe]

Altho the concert has been around for a long time, tubeless tubular(TUFO), and now seeing some makers make some decent supple tires..I think it's GREAT that once again, back to the future, the idea of sticking a tire on a simple rim bed is still 'there'. PLUS, once you have made the 'plunge', just like putting a tube in a clincher tire if ya don't like the tubeless mess and hassle, you can use any more conventional tubular if you don't want to pay the big $$ for a tubeless tubular..

The idea of a supple, tubeless tubular cross tire was shown to us in the shop by Donnelly(Clement) about 8 years ago.

Huzzah!!
