. . . the making of XC FS racing machine - STEREO . . .
Here is couple of pictures to illustrate the data of these suspension systems analyzed last week. All images are from Linkage dxf exports (with zero travel).
Specialized Epic
This is so called "four bar" - the most common multi-link design. I features a short swingarm located on a single pivot, with another pivot towards its end just before the rear wheel - making two pivots between rear wheel and frame. The shock can be operated by a further linkage or a series of linkages. The idea with a multi-link system is to get the rear wheel moving in a direction which cannot be offered by a single pivot system where the wheel moves in an arc around the main pivot.
Trek Fuel
This is so called "faux bar". This suspension system is very similar to single pivot systems. With the wheel connected directly to the main pivot, faux are just a swingarm with a rocker driven shock. Performance depends entirely on where the main pivot sits in relation to the bottom bracket.
Scott Genius
This is again a "four bar", but with a reverse shock.
Later on I will be making analyzes of single pivot, virtual pivot & floating drivetrain systems...
