No mor flats
 
I recently acquired a bicycle with a nice set of Pelissier hubs. I was kind of wanting to use the wheels for another project when I realized that there are no valve stems. This 40+ year old wheelset feels like it has 90 pounds of pressure. Is anyone familiar with NO MOR FLATS. The logo decal is covering the valve hole.

I bet those wheels are pretty heavy.

r0ckh0und 04-25-19 08:44 PM

Yes, the front is about 2lbs heavier than a similar wheel

i worked at a hardware store in a small town in nevada during my highschool years, mostly putting together lawnmowers and bicycle shaped objects. one of the most popular upgrades on the latter was flat-proof tubes. they were basically tire shaped, hard foam rubber rings that you had to stuff inside a tire and cram onto a wheel, doing your best to not tear up tire beads or bend rims.

i hated those things, but we were in goat head country so i got really good at installing them.

...I had to remove a few of those on bikes donated to the co-op. they were a bear to remove, and on most of them I remember just cutting the tire bead on one side to get them off.

Totally thought you just got sloppy typing the thread title.

Amazing!

I installed these for customers at bike shops in around 1979-1980. We all hated them, but customers wanted relief from flats. They were heavy, and the ride was awful. In some cases, the lack of pressure on spoke nipples caused spokes to loosen drastically, causing wheel failures. We used gobs of soap to lubricate the tire beads to get the tubes in.

Remove them with fire...

Those no flat tires are all but useless. If you want to destroy handling quality, fit a set. No more flats for two reasons - there is no air in there, only foam which does not spread impact and load the way pneumatic tires do. And, because the wheels will be so heavy, the ride quality will suffer a lot and you will spend less time riding the bike, reducing possible flats.

I use these Jamaica bought Compass (Chinese not all that special) for about thirty dollars USD a set or 2700.00 Jamacian) and they are superbe. Tough, not bad ride quality and darn near bullet proof, in my opinion. And they have to be bullet proof for the places I ride my Bianchi in Jamaica...

On this topic, What is the best option to turn vintage wheels tubeless? Is there an option?

As a general answer, no. The new trend of tubeless tires requires a proper fit between tire and rim. Mostly you should purchase tires that are rated as tubeless, and modern rims designed to do this.

It'll be interesting to see any replies of those that have found a m

I have seen similar stuff on lower end bikes, I guess what surprises me with these is the Pelissier high flange gold hubs and Gentleman rims and they have a lot of bounce to them.

The best option is to relace to vintage-looking tubeless-compatible rims, I think. (Pacenti Brevet rims could be mistaken for vintage at a glance.)

But like @gugie, I'd be curious to know if anyone has made it work with vintage rims that were known to be a tight fit. I'm thinking like Campy, Ambrosio... MTB "ghetto tubeless" doesn't count though!

why..... what benefit? unless you are going for bigger tires with low pressures and want to avoid pinch flats, there is no advantage and tons of hassles for doing this with higher pressure (60 and above roughly) tires

:50: now get off my lawn
