At 498g, our 500lb/38mm test spring was just a little heavier than a titanium coil. We fitted it to a RockShox Kage RC shock, where it saved 69g. Super Alloy Racing’s springs come in a single length (in this case, 140mm), with a plastic spacer making up the difference. They say a shorter spring behaves in a more linear fashion, so less rebound damping is required and performance is more consistent. On the trail, we found the difference to be very subtle, but it’s something that might become more apparent on long alpine descents, where oil temperature becomes a factor. The thing we really like about SAR’s springs is that they’re available in 25lb increments, allowing you to fine tune your spring rate. If this isn’t something you need, then $150 is quite a lot of money for a relatively small weight saving.
