Rolf Hub R.I.P.
Two miles from home at the end of a 106 mile ride yesterday our front Rolf Prima tandem wheel started wobbling all over the place. Turned out the hub flange had cracked and spokes were pulling out. The wheel has been in service for about 20 months and has just under 7,000 miles on it. So my questions to all you wheel experts out there are: Is it practical/worth it to get a new hub and rebuild the wheel? Is it better to buy a new Rolf front wheel? Should I just go ahead and buy a new rear wheel too (since the bearings in that wheel are getting pretty worn)? Or is it time to get some of those White Industry hubs everyone keeps raving about and build up some new wheels on those?
Thanks for sharing any thoughts you may have ....

My gut reaction is to send the wheel back to Rolf and let them know how lucky both you and they were that the wheel did not let go while you were rounding a sharp bend on a steep descent....

Interesting failure. What's your team weight and what road surfaces are you riding?

If you purchased them as the OEM wheels on your tandem contact your dealer, the builder, and Rolf. If they were after market, contact your dealer & Rolf. They "should" offer to rebuild the wheel with a new hub that does not have the weight saving drill-outs between the spoke holes.

Thank you, TandemGeek, for that very useful information. I'll follow up on it. We are, for what it's worth, a sub-300 pound team. We ride fairly quickly over some fairly rough roads, but we have never hit any major holes, pinch flatted, crashed, or anything like that with this wheel.

"Fairly quick", thats an understatement.
We have the ROlf's that came stock on our Co Mo Robusta, and have had no problems, with around 6000 miles on them. We did have the same failure you described on a set of Bontrager Tandem wheels. We sent them in, Bontrager replaced the hub and we have had no further problems. We used the Bontragers exclusively this year on the each of the CTC doubles we did, including the Terrible Two and both Death Valley events. I'd say let Rolf replace the hub and stick with a great wheel set.

dude, for every person I know with Rolf hub issues, I know ten with White Ind hub issues. How about Hugi or something????
At 7000 miles I'd replace the front and service the rear at a reputable lbs. Also interested in your riding history/team weight.

Tandems break things. Doesn't matter how many people do not have problems with the "Known" Tandem Quality items- someone is going to have a failure.
I know when I looked at wheels 4 years ago- I drew on as much experience of other people as I could. Everyone had different opinions but I made my choice, after consulting with The Downhill Offroaders, paid my money and I am happy.
My choice would not suit everyone as I am offroad- I ride aggressively and went for Downhill Quality. Definitely over the top on weight, but a couple of Front tyre blowouts and several high speed rear ones and my wheels are still going strong. Plus there are the rocks we've hit, and the cars and trees, the mistakes we've made on choice of route and the general misuse.
Still check the wheels after every ride though but Hope Bigun hubs are strong, Mavic EX 729 rims are strong and we have yet to break a straight gauge s/s spoke, even though we were told that Double butted were stronger. Have replaced a couple because we bent them but that is down to me and not the spokes.
I would let Rolf know that you have had a serious failure and see what they can do for you. Even though this is on a Tandem that is going to stress any part used on it- They may be one of the helpfull companies that are around.

12 month warranty, I wouldn't waste my time with a Rolf contact. Also note that Rolfs are about 150grams/wheel LIGHTER than Bontragers. That's why I own Bontrager.

How about Cris King hubs? I have admired them for years but never had any. King offers a tandem specific hub and they have these beautiful colors. I have seen quite a few opinions on Rolfs, Bontragers, and White Ind. Anybody on King's? I get the urge for a new wheelset about this time every year although I'm still on my original Shimano/Mavics that came on my RT1000 almost 5 years ago. One of these days I'll give in.

T'geek on the job!!! I guess what that means then is I know ten people with the regular White Ind badged hubs over the Rolf re-badge. But the scuttlebutt is the same: light, but not durable.

Found this in the cyclingforums link mentioned earlier: "The build is much more important than DB or straight spokes"(Qui Si Parla Ca).

Build enough wheels and you'll eventually form your own opinions on which components work best with each other, make for the easiest builds, and provide for the greatest long-term servicability. Tandems merely highlight many of the weaknesses in poor component selection or builder technique / skill which is why the best insight you'll gain into how wheels for tandems should be built is from the people who actually have experience building wheels for tandems and know what does and does not hold up over the long haul under real world conditions.

At 170 lbs racing weight, I was snapping Revilution spokes like matchsticks on a set of "custom" builds for my Colnago when they first came out. I don't know why you'd want them for a tandem.

On the bright side, at least the wheel didn't break to bits 45 minutes earlier, when we were descending a wicked grade at 50mph out in the middle of nowhere!
Hopefully, we'll be able to get our hands on a working wheel soon. With only that one ride since early September, we're suffering some pretty serious tandeming withdrawal symptoms. Another week or two without riding and you'll probably have to kick us off this forum ....
