I received three of the Rene Herse 584x45-68mm variant in the mail this 
morning, and installed two on my custom Falconer without issue.  The third 
will serve as a spare.  They measured 56g each and the butyl tubes I 
removed weighed 358g combined, so that's over a half-pound of weight 
reduction.  Mine have the black (longer) valve stem, and the very cute blue 
valve caps.

Re: [RBW] Re: TPU inner tubes - Anyone using them?

[Patrick Moore]

I'm watching TPUs, RH TPUs in particular, for possible use if they find a
workable sealant, and this fails to inspire confidence, particularly as RH
claims strong metal valves as a competitive advantage. But presumably RH
will replace or refund for the defective tubes?

Well, I put them on my Riv Road today, was very careful with the 
installation, and had the same result. One of the tubes broke at the valve 
stem immediately on inflation in the tire. The rims are narrow Fir, and the 
tires are a pretty tight fit. I used levers to remove the tire but was able 
to reinstall without levers. New tires with only a few rides on them.

So, I've needed 6 tubes to get 4 tires going. That makes the economics a

I received mine from Rene Herse on Saturday, hope to get them mounted today 
on my Riv Custom - 650B x 48 Switchback Hill tires on Velocity Quill rims. 
 I currently have the lightweight Schwalbe butyl tubes.  I use Velo Plugs

I like the smooth shiny silver stems. The blue caps will end up on the blue

Great question, and one I'd intended to answer in my review, but then 
forgot. I've ridden all my RH 32mm tires with Schwalbe SV16 tubes (and 
occasionally another 28-32mm tube that's been pressed into emergency 
service). I have not used latex tubes in quite a while. I used them on my 
Riv Road with some skinny tires and had two pinch flats on one group ride. 
Haven't used them since. Soon I will try TPU on my Breadwinner, which is 
650x48B. They'll also go on my Heron (after it's back from the spa) and my 
Riv Road, both of which also ride on Stampede Pass tires. 

The big advantage of TPU over latex, in theory, is the air retention. I'll 
know how that's going in a couple of days.

IMO, the question is whether TPUs are worth the substantial price premium 
over butyl. I've just "invested" a pretty big chunk of money into TPU tubes 
for 4 bikes.  In terms of ride quality, my first impression is quite 
positive. TBD on the durability and flat-resistance.

Hi Ted,

[RBW] Re: TPU inner tubes - Anyone using them?

[Ted Durant]

I just received a box of tubes that I ordered from Rene Herse, so here's my 
1-ride review.

Bike and rider weight is about 70kg/150lbs.

First impression ... they are crazy small and light. Clear plastic tubes 
with shiny metal valve stems and "Rene Herse blue" caps - nice touch! 
Unfolding them they seem fragile, especially the valve stem junction.

I ordered some 700x20-32 and 650x45-68. I installed the 700c tubes on my 
Waterford, which has 32mm Stampede Pass EL tires on DT TK-540 rims with 
Velox rim tape. The rear tire is fairly new and had a bit over 500km on it. 
It had been reinstalled a few times (March is a bad time for flats in WI!). 
The front tire is a year old, probably has 3-4000km on it. Both tires come 
off the rim and go back on without tire levers. The tubes are a tight fit 
on the rim and have to be stretched a bit to get around the rim. The tires 
popped right back on, and I inflated to 60 psi to seat the beads, then 
backed off to 45psi. On the second wheel the tube/stem interface 
immediately cracked and I had to grab a 3rd tube. I don't know if that was 
a bad tube or user error. No tire lever, but it's possible I didn't push 
the stem up into the tire enough to ensure the tube wasn't trapped by the 
bead. Given how fragile they feel, it seems it won't take much to cause 
that to happen.

First subjective observation - I can really feel the weight reduction 
handling the wheels. Noticeably less inertia around the perimeter.

First ride was 100km of road riding across the north side of Milwaukee 
(urban riding) through the western suburbs and exurbs to some rural roads 
around Holy Hill. At 900m of climbing, it's a pretty hilly ride but not 
crazy. Some of the road surfaces are beautiful, freshly paved goodness. 
Others are, well, lunar. I often take my Breadwinner out there for its 48mm 
tires. 

Immediate second subjective observation is that the tires sound different. 
There's a "whoosh whoosh" that sounds like nice tubulars. Third subjective 
observation is that the bumps feel and sound different, more "thwip thwhip" 
than "thump thump". Third subjective observation is that it FEELS like the 
tires return more energy from deflection, whether from bumps or, 
especially, when swerving suddenly to avoid an obstacle or making a quick 
acceleration. I have no idea if there really is less hysteresis loss, but 
it feels that way.

No flats today, but clear dry roads, even crossing the north side of the 
city, aren't usually an issue. 

So, I very much like the lightness and the feel of them, and the light blue 
stem caps are a nice touch that will look good on most of my bikes. I'm 
concerned about the fragility of the valve stem interface. No data or 
anecdotes, yet, on durability and ease of repair.

[RBW] Re: TPU inner tubes - Anyone using them?

[Steve]

Garth I was just checking out the Aliexpress link you shared - thank you.

Interesting how some of the TPU tubes sold on the site cost as little as 
1/10th to 1/30th the price of those offered by WTB, RH, Tubolito, or 
Scwalbe. I think I may know how they do it.  

I did notice the RideNow tubes were in the high teen to low twenties, which 
would give me a bit more confidence in them, though Will doesn't sound like 
he feels much love for them. 

I appreciate the commentary. At some future date I'll post a 500 mile 
review - sooner if 
I ditch them.

Yes, as with Eitan I've only heard of the ultralight versions as disc only.

[RBW] Re: TPU inner tubes - Anyone using them?

[Will Boericke]

My Ridenow experience was one ride long.  Hope others have a better one.  
Not-so-slow leaking, and limping home while inflating periodically.  Those 
wheels are now tubeless.

I got mine from Aliexpress for a few bucks each, "ridenow" brand. Haven't 
mounted them yet, but they get great reviews and are available in a few 
different weights. My understanding is that only the ultra-lightweight 
versions are disc-only.
