Rolf carbon tandem wheels

I was looking at the Co-motion Robusta on their website and noticed the caption under the picture said "sporting Rolf carbon disc tandem wheels..." I couldn't find anything on the Rolf website about these wheels. They appear to be Rolf Vigor tandem wheels with avid discs. I wonder if the rim or hub is actually carbon. Has anyone heard of these or did Co-motion just add the word carbon in their description?

From their Robusta Pricing & Options Page:
Rolf Carbon Tandem tubular wheelset (disc only)... $1350
http://www.co-motion.com/specs/robstprice.html

There is a link to an '06 Rolf Catalog on Rolf's website but it doesn't seem to download the .PDF file. Interesting that they are tubular only... traditionally stronger and lighter than clincher rims... and the disc-only caveat seems to address the carbon issues with overheating and rim brake performance.

Might need to drop a note to Dwan or Alan to see what the inside scoop is. They look to be a combination of their 20/24 Vigor Tandem hub/spoke design with one of the new carbon rims.

I spoke with Rolf Dietrich himself at Interbike this year. He said that they are disc only and have carbon rims. I don't think that they're for sale yet.

Throw a set of 25mm COMp GPs on them and you're ready to go.

In our 30+ years of tandeming have only seen 2 road tandems using 'sew ups' on the road. One was back in the 70s and they were telling us how fast they were on their sewups; two flats later we passed them and never saw them again!
Another we saw on a ride in California, but they did the short ride and we did the century.
In racing or track situations sew ups may be a bit of a weight advantage and minimally a better ride than clinchers.

Actually, we know several teams who use sew-ups for racing and they work just fine... no worse or more prone to problems on a tandem than clinchers. Therefore, the typical pro / con arguments for sew-up vs clinchers apply, e.g., unless you really want or need sew-ups, clincher technology is more user friendly and offers excellent performance.

As for the Rolf's in question, it turns out that Dwan and some of the other folks at Co-Motion and Rolf -- noting that both business are located in Eugene, OR -- tested these carbon-rimmed wheelsets this past summer during training for and I believe during the Co-Motion Classic. Like most tubies, they were very light and very durable. However, rim brake performance was a bit lacking on long descents so that's why they will be produced and only sold as disc-brake compatible units... noting that this also mitigates any potential issues with rim / tire heating breaking down the rim and tire carcas adhesives.

Like Mark said, sew-up are no more prone to flatting than clinchers. I ride with a guy that uses only sewups and he can peal off the old tire and have a new one installed qucker than most folks can remove the tube from a clincher. He carries two spare tires pre-glued and folded, held under his saddle with an old toe strap.

For me the problem with sew-ups is repairing the flat tire. It's a PIA and takes forever. Plus the expense of good sew-ups makes a flat on a new tire real hard to take.

I raced for a long time... tubulars are a real advantage. BUT if you're not racing, why bother? I can change a tubbie easier than a clincher. Of course, I had to practice. Yes... they cost a lot, but there's not a tire in the world performs like a Comp GP. That's probably why they're $120. For those of you who think tubulars are outre for a tandem I would also postulate that carbon wheels, especially disks, are as well. Clincher disk? PLease, you're killing me....

What you need is the new Calfee carbon frame + these Rolf wheels + high-end components then strap on some seat and handlebar bags loaded with 2 weeks worth of rations, eye drops, lip stick, money, good luck charms, GPS system, cell phone, female hygene items, extra vest or jacket........

Then have the back seat occupied by a good friend who is 20 lbs over weight and who is not too fond of sweating and see how fast you go...!!!

galen, I saw that team a few weeks ago!!!! Had a 70mm stem on a $9000 custom carbon bike with aerobars, duhhh. You want some griping here, let's talk about stability and stem length.

Does anyone know if Rolf will be producing an all-disc version of the non-carbon Vigor Tandem for all of us clincher people?

Also, what type of fork is Co-Mo running with the front disc brake? If I could pick up a front disc fork and the Vigor Tandem clincher disc wheelset, I'd be in heaven.

As best as I can discern from my brief discussions & correspondence with folks in the know as well as what I've read elsewhere on the Web, Co-Motion will be offering optional dual discs on all of its '06 tandems and the Rolf wheels -- which already had a rear-disc compatible hub -- will also be offered with the front disc compatible hub.

The fork is a new for '06 Wound-Up, all-carbon fork with I.S. disc tabs. Availability when last I saw it mentioned was late December with a price tag near $600.

Hehe, good--I might actually have the $600 to spend by then

Guys, you're killing me here. A disk wheel is a fully closed one-piece jobbie meant for time trialling. It took me a while to figure you're talking about a disk brake compatible wheelset. Forget my comment, double disks in that sense are a nice idea. I would caution anyone from buying a tandem wheelset with carbon braking surfaces: I've owned many sets of carbon wheels (Zipp, Corima, HED) and the braking surfaces do wear, no matter what brake pads you use (Shimano, Bontrager,Corima...). Under the sort of loads a tandem generates, you'd probably run right through your rims quickly. But fine for the world tandem time trail champoinships. Were is that exactly!!!! (I need another heart attack...). p.s.- talk Corima into building you a set of 4 spoke tandem wheels and you'd have something.
