Cosmically good: Ultremo
World Exclusive:
Racing tire with patented Vectran protection belt
Cosmically good: Ultremo
Bohle’s new Ultremo racing tire is a massive technological leap forward: Super-light at just 195 g, triple compound as well as a unique protection belt made of Vectran - material used in the US space program - make the tires fast, grippy and puncture resistant.
“There’s no second chance when landing on Mars” explained a company spokesman from Warwick Mills, USA, a leading supplier of hi-tech fabrics. The company developed an extremely tough Vectran fabric for the Mars lander on behalf of NASA. A similar Vectran textile is now used in Schwalbes’ new tires.
“The newly developed HD-V Guard (High Density Vectran) is – with regard to both puncture protection and weight - the key to a new dimension in the construction of high-quality bicycle tires”, explained Holger Jahn, Bohles Technical Director. “At the moment no stronger fabric exists in bicycle tire technology.” The Vectran fibers used in Warwick Mills fabric are twice as tear resistant as titanium and five times stronger than steel. Woven using a patented process the textile has a cut resistance high three times higher than Aramid, which is used, among other things, in bicycle tires and bullet-proof vests.
Weaving technology is the difference
Of course Vectran can also be found in other bicycle tire brands, but not as a densely woven fabric, rather as loosely bundled fibers - similar to a bicycle tire carcass. “Although strong, it is not the fibers but more accurately the patented weaving technology that makes the difference in puncture protection. “Only densely woven Vectran offers optimal protection”, stressed Holger Jahn. Warwick Mills holds 14 international patents for its weaving techniques, among which is its patent for the worlds most densely woven, high-strength yarn fabric. Warwick Mills innovation makes it the undisputed global leader in this segment. The HD-V Guard was developed exclusively with and for Schwalbe. The Vectran fabric also contributes to the tires low weight, as the Ultremo’s ultra-light protection belt and the super-fine, thinly coated 127 epi carcass helps keep it below the significant 200 gram “barrier”.

“A phenomenal tire. It rolls really easily “, enthused pro racer Lars Teutenberg of Schwalbe Race Support. “I didn’t spare it. On the contrary, I consciously rode through road debris and glass fragments and still didn’t puncture. And for a bona fide racing cycle tire it is extremely light - 195 gram is truly outstanding.”
Triple Compound combines contrasting characteristics
Another innovation is the triple compound that is unique in racing tire technology. The tread has three rubber mixtures. Specially arranged the individual compounds each have a specific advantage. In the tread center there is a hardwearing compound that guarantees durability; proven by Bohle test riders who covered more than 5,000 kilometers.
On the tire shoulders good grip is required and here the second, uncompromising compound improves wet grip enormously. The third - base - compound has no contact with the road, although it is crucial to the tires acceleration: This compound, which was originally developed for time trials, has extremely low rolling resistance - and so is crucial for speed. Lars Teutenberg tested it: “During racing, after each bend I had a 10 meters lead. I now ride into curves at angles and speeds I wouldnt dare doing with any other tire.”
Triple compound allows Schwalbe’s Ultremo to achieve the optimum by combining three opposing characteristics - durability, good wet grip and low rolling resistance - each maximized without impairing the other.
Bohle has invested heavily in the new Ultremo. “We have laid down new benchmarks with this innovative racing tire”, asserted Holger Jahn.

Typical of the European bicycle tire manufacturers, these tires are available in Europe, however the United States is not good enough for their newest products. These tires will work their way here after the European market is saturated and there are more tires produced than can be sold in Europe.

Sizes of Ultremo
Street Use
Greetings.
I ride an ultra-light fixed gear bike on the street as a hobby and for physical conditioning.
In the past, riding on very tire-unfriendly streets, I have had good results with Conti 4 Seasons (no flats nor cuts), and mixed results with the Conti Grand Prix 4000 (no flats but numerous cuts).
Several people have, so far, emphasized the racing nature of the Ultremo, but also the general toughness of this tire, for its weight.
I don’t mind buying two or three sets of tires a year in order to get the kind of acceleration and climbing that very light wheels and tires provide.
Please comment on the suitability of the Ultremo clincher and Ultremo 49 gram inner tube for the street, given the acceptability (to me) of two or three sets a year.
Thanks,
Ken
Would love a 16" version of this for my Brompton folder
Any chance of getting this in a 16” model anytime soon?
Thanks!
Ultremo in 406???
I am currently using a mix of Schwalbe 406 tires on my ICE trike: Kojak in back, Stelvios in front. I would be very interested in seeing an Ultremo 406 for my front wheels, and have been hearing rumors from some distributers re a possible November 2008 406 Ultremo. Is there a possibility of this happening?

Ultremo R tubular availability?
Hello,
I just read about the Ultremo R 180g. Sounds nice. How about the R version in a tubular? When should I expect it on the market? I am interested in a light, puncture proof tire to race in Kona come October 2008. Thanks.

Answering my own question...
Since asking for comments, one whole day ago, I have continued to study the Ultremo tire and tube combination.
I’ve searched out every review I can find, not only regarding the Ultremo, but reviews of similar types of tires in which the reviewers don’t even mention the Ultremo.
The reviewers report about the same flat and cut experience with other tires that I have experienced with the same tires, but the reports of cuts, and especially flats, seem fewer with the Ultremo.
Further, I’ve contemplated the Ultremo in light of a wheel upgrade I plan to accomplish with my income tax refund.
I intended to spend $300 to take 119 grams off my present wheelset (a rebuild with Sapim CX-Ray spokes).
However, I’ve realized, now, for around $100 I can take 120 grams of weight off the same wheelset with an Ultremo tire and Ultremo inner tube.
Putting the two together, spending a total of $400, I can take 239 grams off my wheelset.
For those who don’t think metric, then think 8.4 ounces, over half a pound, just from my wheels.
And not only weight, but rotational mass.
Considering that the Sapim CX-Ray spokes place the nipples at the hub, and not in the rim, this gives me not only a bullet-proof featherweight wheelset, it gives me a wheelset with the lowest rotational inertia imagineable.
Talk about acceleration.
On real world streets, waltzing amongst SUV’s, acceleration means everything.
And, of course, this makes climbing so much easier.
So, if I had to predict the performance of the Ultremo tire and tube combination, based on all the reviews and literature, I would expect to make it through a year on my streets with one front tire and a change of rear tire mid year, for three tires per year.
I have decided to do this, and, in a year, income tax time 2009, I’ll report back, good or bad.

Continuing to answer my own question...
Well, I mounted my new Ultremo’s on my good-weather street bike a few weeks ago and now have several hundred miles on them.
First of all, all the regular bicyclists of my acquaintance, in my community, agree that we have more broken glass on our streets this year than ever before.
What a mess.
That said, by this time last year I had retired my Conti GP4000’s because of numerous cuts, and had returned to my regular Conti 4 Seasons in front and Conti Gatorskin in back.
So far, this year, with more glass than ever on the street, I have no cuts in front and two itt-bitty cuts in back, one of which I can’t find half the time.
The one cut I can easily find barely qualifies as a cut, but more as a “disturbance” on the surface of the tire.
My first impression rates the Ultremo as comparable to my Conti Gatorskin in resistance to damage from road hazards.
The biggest difference comes in handling and acceleration.
I ride on mixed urban-suburban roads in light to heavy motor vehicle traffic.
The precise, surgical handling of the Ultremo tires, along with their fantastic ability to accelerate, gives me a much greater margin of safety than I have felt in the past.
In addition to the low inertia of the Ultremo’s, they have the most positive power transfer to pavement I have yet experienced, and my bike literally “pops” forward when I want to accelerate.
As a side note, the Ultremo’s have a relatively loose fit, and one can mount them on the rim by hand without tools.
Partly because of this, and partly because of my own mounting technique (or lack of technique), the initial mounting of these tires resulted in the failure of the two Ultremo tubes I had purchased with the tire.
Bummer.
I presently ride with Salsa Superlite tubes, which weigh about two thirds of what conventional tubes weigh, and twice as much as Ultremo tubes.
Eventually I’ll try remounting my Ultremo tires with Ultremo tubes.
Together, the Ultremo tires and tubes represent a HUGE reduction in rolling inertia for a relatively low price (compared to upgrading wheels); and this corresponds to a HUGE improvement in acceleration, braking and climbing.
And again, the best handling tires I’ve ever ridden.
Your friend in Bend, Oregon.

I have now ridden with the
I have now ridden with the Ultremos for about three months and for over 2000 miles.
As I wrote before, we have more glass on the streets, this year, than I have ever seen.
I have had one flat in the rear tire from something very fine coming through the sidewall; or, perhaps I should say I have had one slow leak that resulted in the tire going flat overnight.
It took me awhile to find the leak, and I saw no evidence of what caused it, except that something, perhaps wire, had come through the sidewall leaving no mark on the outside of the tire and only a tiny disturbance on the inside.
A few days ago, after a hard training ride on a very hot day, I wiped down my tires and felt in two places a slight separation or bubble under the surface of the rear tire.
I attribute this to the heat and to my weight, as I weigh about 235lbs with all my gear.
In addition, I ride a fixed gear bike, do all my braking through my rear wheel, and I climb a lot and very aggressively.
The front Ultremo, after 2000 miles, remains pristine in appearance and function.
I decided to replace the rear tire with an almost new Conti Gatorskin I had hanging on the wall, until I can get another Ultremo for the rear.
I found the difference in handling interesting.
Having the Gatorskin in back noticeably softened my acceleration and also lessened some of the surgical precision in turning that I had come to take for granted with Ultremos front and rear.
I don’t see this as a failing in the Gatorskin, as someone else might prefer the slightly more relaxed handling of the Gatorskin.
In the past I rode with a Gatorskin in back and a 4 Seasons in front, and I liked the handling until I rode with Ultremos, and now I prefer Ultremos.
But then, I like an agile-handling bike.
The owner of my lbs has noticed how well my Ultremos have held up against the glass on our streets, and he has put Ultremos on his geared road bike.
I’ll order a new Ultremo in the next day or two.
lots 'o glass
might this have to do with the huge population of college kids in your town?
