Rolf Prima wheels on cobbles...?
hello
I have a Calfee tandem with a Rolf prima tandem wheelset . The Rolf tandem wheels, are they suitable to ride the Belgian classic road races , like The Ronde van Vlaanderen, i mean are they suitable to ride over the cobbles here in Belgium, Europe. Anyone who know's more about this...? thx for replying |
Our Rolf's lasted 12-15,000 miles and finally gave out. The roads where ride have many sharp edged potholes. Smooth edged cobbles are a different thing altogether. We now have 2 sets of wheels, and change according to road conditions. No first hand experience with cobbles, but overall weight has something to do with longevity. Our combined weight is 290lbs.
|
I've ridden those roads but I don't have the Rolf wheels. My inclination would be to use another set of wheels. You're going to want something that is a little more compliant anyway to ride on those cobbles anyway. I ran 32 spoke Mavic OP Ceramic wheels. They worked really well.

We moved from the US to Poland last year with our tandems. Every ride that we do includes at least 5 to 10 k of cobblestones. We have not had problems with our 32 spoke Velocity Deep V rims on Chris King hubs. I am very hesitant to go to anything with fewer spokes on the cobblestones here. The tandem is not as easy to maneuver through the rough sections than a single bike so the wheels (and stoker) take a serious beating.
If I were to change anything on our current setup I would use a fatter tire than the 25mm Michelin Pro Race tires on our tandem, but I have not been able to find a light, high quality tire any wider than these. We tried some Schwalbe Marathons in 28mm but the tread felt so squirmy on uneven pavement that I changed back to the Michelins after one ride. |
My experience with Rolf's is they are more harsh than traditional wheels and agree with Homeyba for more compliant wheels. Will they hold up? Many variables but I would put my money on 40 spokes hand built wheels.

We second the motion of Velocity rims (ours are Aeroheads, 32H front 36H rear) with Chris King hubs. Our team weight is rather light: a tad under 250 lbs.
In over 30,000 miles on our c/f tandem have replaced rear rim twice. Another wheelset to look into would be Topolino; have them on my single bike and love them. After 10,000+ miles have not yet had an issue or needed to even true them. They do make a tandem specific wheelset. Am familiar with Flemish cobblestones as I was born/raised in West Vlaanderen. Let's face it, while de Ronde features lots of cobbles there are better stretches of road in Belgium! Try riding some of the cobbles on your Rolfs . . . you be the judge! Pedal on!

We've ridden our Rolf's on dirt roads without problems. In all likelyhood they'll hold up fine. However you're putting additional wear and tear on them that will ultimately hasten their eventual failure.
I think your tire selection is likely more importnat than the wheels I'd run the widest tire you can fit on them, and fit on your frame, which is likely 28mm (Continental 4 seasons are a decent tire in 28mm). If you were going to spec a high end wheel with riding cobbles in mind, I'd look at the Topolinos, which reportedly give a smooth ride. |
We have 2 sets of wheels, Rolfs and Deep V's on WI Hubs 36 h, sapim cx ray spokes. For us, the Rolfs seem more compliant than the traditional build wheels, both ways. I can watch the Rolf's front wheel wobble at speed and I suppose the rear's doing the same thing. Most say just the opposite.

Once again, cobbles represent a good application for that 2nd set of conventionally-built utility wheels with 36* or 40* spoking and a rim that will handle a larger volume tire like 28. Of course, you'd want to make sure your frame, fork and brakes will accommodate a given brand/model 28mm tire on your rim of choice without creating any interference issues and with "some" free space between the tire and fork/frame stays, etc. Would the Rolfs handle the cobbles? Probably, but it would clearly use up some of their service life and if by chance a spoke broke field repair is at best a challenge even if you have the spare spokes (2 different lenghts needed depending on which spoke breaks on which wheel) and spoke nipple driver in your repair kit. Same story on the Topolino wheels... do you REALLY want to beat up a set of $1,500 wheels that can't be repaired in the field? |
^ that's why I said if you wanted to go with a set of high end wheels. I still think the shock absorbing nature of the topolinos would be better suited than the Rolfs. In either case however, you're risking destroying the wheel, and very likely shortening its useful life.
It becomes a question of how much you're willing to pay. Also I took the question to be in the context of the OP doing the cyclosportifs before the Tour of Flanders, and Paris Roubaix. If you're trying to do those competitively, being able to repair a wheel is likely not your primary decision criteria. |

I was reading in the Cyclosportif assumption from the " are they suitable to ride the Belgian classic road races , like The Ronde van Vlaanderen"
Only way I know to "race" the Ronde on a tandem is to do the Cyclosportif the day before. And I agree that tire size, and therefore air pressure are going to make a bigger difference. |
I'd leave the Rolfs at home and ride my 40 spoke wheels with the fattest toughest tires I could find, which is probably 28mm gatorskins on the Calfee. I'd carry at least 3 tubes and a folding tire just in case. Cobbles are tough on you and the equipment.

thx for al the reply's, i'll go for a extra set of wheels, with more spokes, not gonna risk the Rolf's....i'll keep these for Liege-Bastogne-Liege..
I'll report how it al went on the Calfee during the Ronde van Vlaanderen.:o |
Eet nog een beetje patate frites voor ons!
Voorspoed! Rudy en Kay/zonatandem |
frites=not good for cyclist !!!!....;)

Talk about hedging your bets. |

In other words, they won't hold up fine.
Talk about hedging your bets. So if you want them to last a long time, I wouldn't use them. If you're ok with replacing them, or rebuilding them every couple of years, then you could use them like that. |
Roads are like cobbles around here and ours lasted 15,000 miles.
