Or use disks. That's one of the reasons we got disks on the new tandem, though I still alternate front/rear to allow the disks themselves to cool.
It's been interesting to see how people limit their speeds. I do if I'm unsure of the road but if it's a nice, visible road with no cross traffic I tend to let it roll. We've hit 50+ on the tandem a couple of time (on Tour de Blast we actually used the disk as a light drag because there were state patrolmen around and they were rumored to ticket cyclists breaking 55mph - which would be insanely easy coming down from Johnson ridge on a tandem!) Cindy has been fine with it, in fact I sometimes keep it slower than she would like since I have a better idea of the handling/stopping abilities of the big bike. -Ken On Fri, Jul 13, 2012 at 11:28 PM, Bill M. <bmenn...@comcast.net> wrote: > On a truly long and steep descent, trying to come down too slowly has its > own peril - overheated rims and blown tires.
