- Cannondale’s 2 shock downhill bike is official
Cannondale released a video today showing off the new dual shock downhill platform. Looks rad!Posted 3 weeks agoraybanwombleMember
but not on front ends eh rayban?
Hah! 😀 Cheeky point taken
Ahem, well teles allow you to keep the leverage ratio on the damping linear whilst progressively increasing the spring rate.i I guess the positional effect of the leverage ratio on damping cannot be played with as easily and separate to the spring rate/leverage on the spring – but you can also use positional damping circuits. There’s enough room allow you options in terms of separating damper functions into each leg, it just adds weight which most mtbers hate.
It’s late, I haven’t entirely got my head around the Cannondale. I’m guessing with the Cannondale, using different leverage ratios for spring rate and damper can help alter the range of shaft velocities on damper? My brain has been fried by some nasty maths – but we can argue about this on Thursday evening?
Edit: Watched the video – the axle path looks like it might be interesting. It’s got some kind of idler with a four bar setup.Posted 3 weeks agochiefgrooveguruMember
To be pedantic, it isn’t two shocks. The coil spring is attached to a progressive linkage; the hydraulic damper is attached to a linear linkage. So it’s the usual pairing of coil spring and damper, just mounted differently, separate rather than concentric.
Makes a lot of sense – with a linear linkage coils bottom out too easily or are too firm at the start of the travel, whilst with a progressive linkage dampers are either harsh/slow at the end or soft/quick at the start.Posted 3 weeks agokelvinSubscriber
There was that other twin shock frame a few years ago, name escapes me, that used 2 rear shocks, they worked in different parts of the travel from memory.
The original Cannondale Gemini prototypes?

It’s been seen running with 2 shocks, 1 shock, and 1 shock plus second damper, apparently. They look to be using the frame to try out lots of ideas.Posted 3 weeks agomashrMember

Probably a good chance that the spring shock (for want of a better word) had its guts ripped out of it so they didn’t need to make their own tube for early testingPosted 3 weeks ago
