Bicycle rear suspension

A bicycle suspension system for attaching a rear wheel with a rear wheel axle defining a rear wheel axis of rotation, to a front triangle, being a component of a bicycle equipped with the suspension system, having a bottom bracket defining a bottom bracket axis of rotation, the bicycle having a right side being on the right hand side when the bicycle is viewed from the rear, the bicycle suspension system comprising:

• a rear triangle to which the rear wheel axle is mounted;
• a shock absorber interposed between the front triangle and the rear triangle;
• a first link:
• pivotally connected to the front triangle at a first link front triangle pivot defining a first link front triangle pivot axis;
• and
• connected directly or indirectly to the rear triangle at a first link rear triangle pivot;
• a second link:
• pivotally connected to the front triangle at a second link front triangle pivot defining a second link front triangle pivot axis;
• and
• connected directly or indirectly to the rear triangle at a second link rear triangle pivot;
• whereby, the suspension system is reversibly compressible from 0% compression, being an unloaded at-rest position, to 100% compression;
• and
• wherein:
• at an optimized suspension compression, both of the first link front triangle pivot axis and the second link front triangle pivot axis are on a line parallel to, and no more than 30 mm from, a notional line passing through the rear axle axis of rotation and the bottom bracket axis of rotation;
• and
• the optimized suspension compression is in the range of 10% to 100% compression
