Sit bone pain
The larger the area, the lower the pressure.
This physics law implies an advantage for the SQlab step saddle concept. The area does not - like with other ergonomic saddles - need to be reduced in a contra-productive manner with holes and cut-outs.
Pressure= force/surface area
What is the meaning of this with regards to a bicycle saddle?
Pressure = pain causing magnitude, which should be as small as possible
Force = magnitude determined by body mass and gravitational acceleration
Area = useable surface area of the saddle and cyclist
Causes of painful sitbones
Saddle to narrow
More performance - less pain
SQlab offers the largest selection of saddle models in different widths for all areas of application.
Wrong saddle shape
More free space - less pressure!
Too soft saddle
Cause - too soft saddle
leads to sinking sit bones
SQlab saddle models in different saddle firmnesses adapted to riding duration and area of use
A too soft saddle usually becomes very uncomfortable after approx. 30 – 45 minutes on the bike.
Soft saddles are generally only suitable for short distances!
Familiarization of the sitbones
The sitbones are capable of getting used to a high pressure load and the discomfort will reduce. At the beginning of the season, or when switching to a new unfamiliar saddle shape, pain and discomfort in the sitbones is normal. Familiarization with a new saddle can take approx. 5 to 6 rides.
At least two days of rest should be scheduled between the initial rides to give the already sensitive muscles and tendons time to respond.
SQlab lists the hardness of the padding material on the saddle. We have developed a measurement unit called SQ Shore, which takes into account the combination of both cover and padding materials.
Painful sit bones get used to the strain at first, which is quite normal especially in the spring after a long winter break or during the first test drives on the usually unfamiliar SQlab step saddle.
The pain originates at the periosteum. The pressure is less the problem, rather it is the shear forces caused by the pedaling motion. The slight but constant movement of the pelvis on the saddle provides painful shearing forces on the periosteum.
The SQlab active technology provides some relief as well as a chamois cream. The best solution are our new pads: The SQ-Pad 11 and SQ-Pad10.
