When tubeless becomes fool proof and effortless which it as yet does not sound to be I will use it.


I think it is pretty damn close right now....I don't see road tubeless as being significantly different than cross or MTB tubeless in terms of set-up / execution. The biggest thing holding it back, IMO, is still tire selection. Not a lot of choices out there (good or bad). one other important point....for MTB / cross, you can use pretty much any tire and use it tubeless with the proper set-up. This is NOT the case for road. You absolutely MUST use a tubeless specific road tire...the pressures are so much higher than other applications that using non-tubeless specific tires carries a significant safety issue with it.

Still a few years out methinks.

I'll switch over in a few years when the reliability is totally dialed in and been out long enough where I can buy some slightly used snazzy wheels from someone mezmorized by the latest and greatest who's offloading them cheap to buy something even newer.

Adjusted the pressure this AM to 70 frt / 75 rear.....just about perfect. Wheels just sing along the roads at speed. Amazing ride.

May drop a few psi out of the rear still....maybe 72/73. We'll see.

Ran even 70 on both wheels today...sublime.

Have to pump up before very ride, but no different than using latex tubes....

I've been running road tubeless for 5 years or so. 98% positive all the way around, but the 2% is a bitch. When you cut the tire beyond what the sealant will seal, it's not great. This has happened to me twice in 5 years and both times I was calling for a ride. I run Campy/Fulcrum wheels which are two-way fits so they are made for tubeless - no conversion or tape required. I have had the best luck w/ Schwalbe Pro One's as far as the ride goes. I used to ride Hutchinson Fusions back in the day when your options were extremely limited. The Specialized Turbos are supposed to be nice, but they are expensive.

The "throw a tube in if you get a flat" argument is sketchy at best. For starters, getting those tires on/off on the side of the road is a challenge. Secondly, the mess associated with sealant all over everything makes it damn near impossible. One suggestion to those of you riding tubeless now is to carry one of those plug systems. There are multiple systems out there . . I think mine is a dynaplug or something like that. I had a buddy cut a tire and had sealant shooting all over. We waited for the air to leak out, inserted the plug, threw some air in it and limped home. They are a decent solution to get you home, but that's about it.

Lastly, I've had the best luck with Orange Seal - Endurance for sealant. The "endurance" version is supposed to last longer without drying out. It seems to be true so far. I used to have to add juice by the 4th of July, but so much anymore.

CK - I know you don't have other tubeless tires to compare them to, but do you like the Conti 5000's? I was thinking of giving them a shot.

Great post thanks. One bit of wisdom from the motorcycle side, where road tubeless (at far lower pressures than bicycles) has long long been firmly established and preferred: tread punctures are handled easy peasy, but sidewall cut, no, you are screwed. Fortunately that's rare on a moto. Fragile bicycle tires are more vulnerable to these cuts, depending on where you ride. Gravel road guy here, still with tubes, but watching closely.

Funk, I LOVE the Conti 5000’s....super comfortable and a fast ride. There is a certain road feel/buzz to a fast tire that I can’t describe, but these definitely have it. I routinely find myself coasting on wheels much longer than anyone else, just buzzing along. Can’t speak to their durability yet, though...

I w@s tempted to go with the Schwalbe’s, but reviews seemed inconsistent...some love ‘em, some complained about durability. Sounds your experience has been positive, though...

The Schwalbe's are decent. Again, they are a noticeable upgrade from the Hutchinson Fusions of years past. I kept re-upping on them because they are affordable and honestly the roads are so lousy around here (Michigan) that I seem to cut one every few months. My buddy swears by the Specialized, but he works at a shop and gets them at a sizable discount. I just ordered a set of 5000's per your review. Thanks.

Make sure to follow-up and let us know how you like them once you get them on!!

Saw that.  That one is on the rim manufacturers.  To be sending out rims with edges that can cut tires, especially on race bikes where tire casings are minimal, bikes are regularly ridden out of saddle and are cornered hard?  Is this a plan to reduce their market?

Leonard Zinn makes an interesting point,  Aluminum rims are drwn through a die that is milled.  Milling cutters cannot do sharp edges parallel to the shank because they spin.  So no aluminum rim will ever have a sharp edge.  But CF rims are molded using two piece molds.  The rim beads are the logical place for the pieces to mate.  This means flashing - thin, brittle and potentially both very sharp and jagged.  Perfect for sawing tire casings.

Lesson?  Check those beads and be prepared to sand.

Tubulars keep getting closer and closer to re-entering my life.
