For those who are using Stans, how are you putting the stuff in your tires? I've tried with the small bottle, and it tends to make a mess. I've seen kits that seem to be a 5cc syringe, a heavy gauge IV cannula, and an extension tube. Are those good for the job? Despite riding sew-ups since the early eighties, this autumn was my first time trying sealant.

I remove the valve core then put the small bottle tight against the valve with very little mess.

I like using the Park Item # TSI-1. Hardly necessary but, for me, usually makes for a much cleaner job making it worth the cost.

I use Orange Seal which is available in a small squeeze bottle with a clear plastic hose that fits over the valve stem. As mentioned above the trick is to remove the valve core first. Also, position the wheel with the valve somewhere around the 3 o'clock or 9 o'clock position when filling so that the sealant inside the tire flows away from the valve.

I have such a kit, but the syringe is 60cc. The tube screws onto the valve stem. Works well. Just need to clean it well after use.

And I learned a new word. Thanks.

I do remove the core, but sometimes if the tire moves at all, air coming out pushes Stans out of the stem making a mess. I figure the cannula would get the stuff past the stem making this problem less likely.

You're right. It's much bigger. 5cc would be less than 1/5fl oz. Not very useful.
My oopsie.

I do wonder why some of those kits have a stopcock on the extension tube. Consequence of repurposing medical equipment maybe.

Rule one; don't use sealant in a tubular tire with latex tubes. Too sticky and when its reinflated, can tear the latex tube.

I've been using sealant in tubulars with latex tubes for a few years. But I make sure that my tubulars never go completely flat between rides, which is bad for the tubes anyway if the bike is sitting upright on its tires. This only requires me to re-inflate every week or two, which might get to be a chore if you have a collection of 20 bikes but I only have three bikes with tubulars.

My method is to not use sealant until I have a flat. Then, hopefully, I reduce the chance of an issue and I am only risking a tubular that I would need to repair anyways.

While I'm mainly riding Veloflex these days, I do have a few old Conti Sprinters I'd like to marshal into duty as spares. The main issue is that I've never found a good adhesive for sticking the base tape on those. Good cotton tires do well with Val-A Tear Mender. (Trust the Bish!) This stuff doesn't work in any way with the Continentals. Has anyone tried E6000 for this job? Any success here?

You can buy a basting syringe at a dollar store. The metal needle is small enough to fit inside the Presta valve sleeve once the valve is removed.

Incidentally, I've also experimented with several high strength industrial neoprene adhesives from 3M, and the adhesion is still poor. Basically, the carcass rubber seems both very slick and impermeable to most glues. Maybe there's a solvent prep that might help, but I've not experimented here.

Here's a question for the peanut gallery: why the hell is Conti glue so damned expensive these days? My old 350g can for which I payed $25 at my LBS is nearly gone. No matter where I look, it seems they want about $70 for the same thing. While it's been a while since I've purchased glue, the jump in price seems unreasonable to me. The tires themselves have gone up a bit, but by a reasonable amount.

Yep. I used to use Continental also. I’m about 1/2 way through my can of Mastic One at the moment. I’ve been using it on my Continental tires without problems😉

My apologies - I missed this question!

The rims are Mavic Reflex SUPs with machined sidewall treatment. Compared to vintage tubular rims (on which the braking surface is a mere suggestion), the machined track is a game-changer.

I found them on Ebay, from a seller in Australia. They pop up from time to time. Good luck in your search!

It was covid time and affordable spokes were like hens teeth. I had a tubular repair build (two broken spokes side by side on the same ride, used, mismatched build at that). The calculator calls for 296 and 298, and toward the end of that madnness I was able to find a box of 298. Figuring I would build both sides with this length. What say you members of the totally tubular thread? Mavic Monthlery Pro with Campagnolo Record. Just this afternoon I got it taken apart. Now that it's written down I realize I could potentially nip 18 of those spokes if necessary. I'm thinking it's not necessary.

I'm not looking to change glues. I'm just looking for an good explanation. BTW: I did think of switching a while back, but two things dissuaded me: 1) it was out of stock everywhere. 2) I understood that a mid-ride change was a lot harder with Vitt than with Conti.

In my case, I'm riding Veloflex, but it's more a matter of wanting to stick with a known quality, and not wanting to need to take the rims down to bare metal or change toss tires previously glued with Conti if I patch them.

All of this requires a hard-blown set of tires with which to transfer the info to my hands, feet, and butt. Sounds funny, but it's true. Low pressures induce a feeling like being on a pogo stick, and the feedback is mushy and inconsistent; I cant plant the rear end, much less do anything with precision regarding the front end, with tires performing with too much bounce/rebound.

High pressures do allow the occasional skipping of the rear or front tire, but again, feedback is such that I know when it's going to happen, and reflexes compensate. Like catching a moment of oversteer in a car.

The Alpina was fitted (unknowingly) with the aforementioned Elites, and taken up to 115psi, which was still squishy and ponderous-feeling, when someone here noted the sidewalls said the pressure was limited to 105psi. First time I noticed the rating didn't match the ad copy, and I couldn't imagine the feeling if I were to let out 10psi.

Anyway, those are still on the bike, but I didn't bring it with me and it won't see much use (now a zero bike in WA), for good reason. The 'cushy ride' many describe when running tubulars at lower pressures simply translates into 'bouncing' for me and my sensitive contact points. I know I'm an outlier

DD
As I read this I'm reminded of the extreme noodly feeling my 79 Trek 930 gives with low pressure tires, Thanks!
