Softride
Beam, S&S BTC, Trapezoidal Tandem
Design
Introducing
Concept Technology's Trapezoidal Softride Tandem
geometry. I designed stiffness into it by using 1-3/4" top and
bottom tubes. The Softride Beam is attached to the
Trapezoidal tube that extends from the rear BB through the top tube. The
Trapezoidal design stiffens the center geometry. Oval seatstays
and chainstays are used to strengthen the rear
rhombus. Yes, it lacks many tubes that you might be used to seeing but with
this design, those tubes were unnecessary. Between the top & bottom tubes,
plus the 1-3/8" downtube and 1-1/2" headtube, the handling is precise and confident.
For teams requiring a stiffer rear triangle, I use a traditional rear triangle
design, extending the front deraileur tube up to the
top tube. I also will use 2" top and bottom tubes for riders who need the
extra metal.
