My wife and I are currently training up for a ride this fall from Portland, OR to SF, CA. We're doing it on a supremo, and while we're not going totally unsupported (we're only carrying a tent, sleeping bag and clothes) it's still about 40 lbs of additional gear.
With that in mind, I contacted Rolf to see what they thought about these wheels and that particular task. Here was the reply:
Thanks for your email. The most important thing to keep in mind and you
have already acknowledged it, is the fact the tandem wheel was designed more
for racing/performance compared to touring with massive amounts of gear.
With that being said, our tandem wheel should be fine for this trip. Just
as a precautionary measure, it wouldn't be a bad idea to order a tandem
spoke kit (2 fronts spoke, 2 drive side, and 2 non-drive spokes) along with
a nipple driver tool. I'd be surprised if you needed them, but it would be
a nice security blank.
Please let me know if you have any questions.
I know a lot of you like 36-40 spoke wheels on velocity Deep-Vs with the WI hubs, but I REALLY don't like the idea of making this trip more expensive than it already is. So my question: what are the honest odds we have an issue, and how much would it cost to build a custom wheelset+cassette?
