Chit, that's a wild looking bike, Squalo!
Foo
It was pretty radical in its day Foo - first appeared in 1996. Nowadays the Cannondale Super V is a bit of a curio, and single-pivot rear suspension is something of a compromise - but the mods I've made maximise the good points of single pivot, and minimise the bad points. It's called a "Uver V" by the Super V afficionados, where you take an old cross country bike and turn it into an all-mountain bike, which climbs like a mountain goat and has the suspension travel to take big hits and jumps when descending... and weighs 12kg.
Note the changed rear swingarm, that's the key - a lighter stronger arm than the original, which looks awesome, but breaks. And you take some meat off the frame-mount for the shock, and re-drill the mounting hole, so you now can fit a 7.5" shock to get the additional vertical travel at the rear - from 3" to 6".
Then you ditch the 'Headshok' (which is a great design, but limited travel) and fit headset converters to run a modern long-travel front fork system - mine uses 1-1/8" upper bearing and 1.5" lower bearing, and I've gone from 3.5" travel to 5" travel.
Then you get disc-specific wheels (Crank Bros 'Cobalt' on mine), and all the other bits... then you go completely overboard, and spend 40 hours hand-polishing the frame and smoothing all the welds, and get custom decals made up, and really go to town on red anodised bits
It's grandpa's axe - seriously, only the main frame remains from the yellow bike.
My son's Cannondale was equally radical for its day. Rear suspension has carbon fibre chainstays, no pivot - the carbon fibre has a skinny point that actually flexes to act as the pivot. The seat stays are moulded plastic, they just transfer the suspension movement to the shock. And then there's the front suspension (have a good look at the pic!). That bike was $8.5k when new in 2005, it's the 'Team' edition Scalpel that won the world MTB cross country championship that year. Weight is 11kg with pedals, which is why I bought it for him - he only weighs 35kg! (he's 9)
