New Shock Tuning Options for Cane Creek Double Barrel Users
Feeling like you’re not getting the most from your rear suspension? As an additional tuning tool, the spring rate of the DBAIR can be adjusted through the use of air volume reduction spacers (included with the DBAIR). For bikes that have a more progressive leverage ratio, Cane Creek now offers new XV (Extra Volume) air cans.
Air volume is not the same as air pressure adjustment. Air pressure should be used to achieve the correct sag value (see Tuning Field Guide). If the bike bottoms out harshly, or too frequently, reducing the air volume (using spacers) can provide a more progressive air spring. A more progressive spring will prevent harsh bottom-outs, since the spring will be “stiffer” as the bike gets closer to full travel.
Having more air volume (using an XV air can), is recommended for a sub-class of bikes that have a significantly progressive leverage ratio. More air volume will provide a more linear (less progressive) air spring. A less progressive air spring will allow a rider to ride with more High Speed Compression while still allowing full travel of the bike.
