Thanks! I understand you not having worked up to trying that descent yet. You guys do have those runaway truck sand pits every few miles, don't you? 😄
I'll let you know how the drag brake works on my rig...next Spring probably. We are extrememly limited in long descents here. I may have to travel over to Pennsylvania or down to West Virginia to get a chance to test the brake function and see how much heat I can put into those rims. And to do that, I want some seat time before attempting to fly off Fancy Gap in West By God!
If I managed to sail me and my wife off some guard rail-less fast sweeper in the Appalachian Mountains and into an abandoned coal mine's spoil pile and kill us, she would never forgive me!
I know these modern tandems grew several inches longer in the stoker's quarters and that didn't do much for the sports car-like handling, I'm certain. The other day I was comparing pictures of a 1970 Schwinn Paramount touring tandem (as opposed to their racing model) to the newer Burley-Co Motion-Santana-Ibis-Da Vinci-etc. designs and that Paramount was a downright short wheelbase road racer compared to even Santana's self-described 'Team' and 'Elite' model line of tandems.
All I read is how fast tandems go down and that air-braking by sitting up will keep you around 50 MPH on most descents (depending on grade percentage and wind, of course).
I'm machinist enough to retro fit a modified weld-on disc mount, complete with chainstay reinforcing trusses, onto the 160 MM wide hub and lose the drum brake. One of those huge tandem discs at the rear and a good linear pull up front should get even a daring pair of riders safely down anything I want to slog a tandem up. This will be an interesting ride and learning experience, for sure. After years of wrestling Harleys around with drunk chicks on the back...I think I got this one!
