We've been using the 2017 version of the Rolf carbon wheelset for about a year.

So far performance has been flawless with no trueing required or evidence other problems.

Only issue noted is the tall rim profile may have contibuted to a high-speed wobble we experienced under some conditions, but sensitivity to this issue and some adjustment in stoker positioning has largely eliminated the problem.

We spec'ed them based on the low weight, as our old engines no longer put out sufficent watts to take advantage of the aero benefits in most situations.

My philosophy on tandem wheels is different than some on the board: Tandems are such a small market that it can be difficult for many vendors to gain sufficient experience. Rolf has been in the tandem market for a long time and that buys them a lot of credibility with me (We've seen the improvements in their alloy tandem wheel design as a result of lessons learned over the years).

We've never used Spinergy, but they seem to have similar experience.

I would need a lot of familiarity with a custom builder to have the same confidence in their product for such a niche market as tandems.

Let me know if you have further questions.
