Spinergy's ...
Some open source 3D printing and inventory of new (old) bike
Giant Cadex CFR-1 in immaculate condition for its age. The frame is bonded carbon and a dream to ride. Comes with the coolest Spinergy Rev-X wheels. You wont find any in better condition.
This is the 1993 model, an absolute classic as it is the first of the successful CFR range. The CFR-1 is the top of the range complete with Shimano 600 groupset.
Spinergy Rev-X wheels are icons of 1990's cycling until they were banned by the UCI in 2001 as they failed a new safety standard, of which there are conspiracy theories. Apparently the Rev-X's come in four generations, with this pair being the last. I am not entirely sure if these are superstiffs; but they do have an additional finger of carbon layup on the inside of each spoke.
Spinergy also sold stiffeners, known as X-Beam's for these wheels which supposedly improves lateral stiffness. An X-Beam was an additional plastic brace that wedged between each spoke. These came in three different colours for different tensions provided. There is quite some controvesy as to whether these are effective - with a good technical discussion here
It seems these are incredibly difficult to find these days, but can be 3D printed based upon an open source design here. The Linux 3D/modelling application blender can be used to edit/tweak the design.
