Rear Shock Geometry


Recommended Posts

Let us talk rear shock geometry.


The basic placements od the rear shock currently around on bike vary between:


Shock below the top tupe - horisontal

Shock inside triangle on the seat tube - vertical

Shock outside triangle on seat tube - vertical

Shock on one side of rear triangle - roughly 45 degrees like Merida


Why the different geometries?

Does it matter?

Pros and cons to have the shock outside the frame triangle (space for 2 bottle cages for eg.)


Would like to hear youe knowledgeable comments...

It doesn't make a difference where the shock is placed, the difference comes in the linkages operating the shock, leverage ratios, single pivot (most common) four bar linkage (specialized and a few others), etc...thats without getting too technical...

Yep, placement of the shock, although having little to do with its performance does still effect the ride of the frame. On a downhill frame a shock weight is a HUGE percentage of the weight of the frame so its placement largely effects the centre of gravity of the frame, thus having an impact on how the frame handles.
