Notwithstanding the tandem-specifics of this discussion, how does the emphasis of a granfondo on speed coexist with the lawsuit currently underway related to the supposed Strava-induced fatality? I've never ridden in one of these events, but I've developed an image of a true peleton maintained even on fast descents. Is the indemnification provided by the participants to the organizers consistent with this sort of (encouraged?) behavior.

In a normal organized ride (100K, century, etc.) I think we all recognize that tandems have to be able to pass on downhills and must do so safely. Any single rider must also recognize the need to provide safe passage for faster descenders whether single or tandem. Our tandem experience is limited to only 9000 miles, but I've generally found it very safe to pass a single rider or a small group of pacelining riders; passing a larger group or two abreast doesn't hold much interest for me although hanging back can be very hard on the brakes.
