EXT Springs are developed for a long time use, thanks to improved mechanical characteristics and its material directly derived from motorsport. This can be adjusted to suit your preferences and to either hold in its firm setting more frequently, or not so frequently. The SID SL is the all-out cross-country racing fork in the lineup and in 2023, it got a range of updates. TurnKey damper on Judy [B1] and Silver TK [A2] and Silver TK [A3], Motion Control damper on Gold RL [A2] and Gold RL [A3].

Though what's important to note is the Ultimate's damper has been machined to shed weight, whereas the Select's damper hasn't. The new Superlight V2 Springs are developed using exotic materials mainly used in motorsports applications. There are 150-, 160-, 170-, and 180mm travel options for both 27.5- and 29-inch wheels and the Debonair air spring system is used in the forks. The Pike Select gets a more basic Charger RC damper, with easy-to-adjust low-speed compression and rebound. Apart from the Pressure Relief Valves, which can be retrofitted, the Pike Select shares the same DebonAir+ air spring, seals and damper fluid as the rest of the Pike line-up. Adjustable rebound on Judy [B1] and Silver TK [A2] and Silver TK [A3], adjustable rebound and low speed compression on Gold RL [A2] and Gold RL [A3].SID SL is an out-and-out race fork that gets 32mm stanchions, 100mm to 110mm of travel, a 44mm offset, comes for 29ers only. This fork uses the latest Race Day 2 damper. Red hot “BoXXer Red” Signature Coil colourway and Signature Colour matching decal options available. This is the mid-range damper and it comes in a few different formats. All are emulsion dampers, where the damping oil isn't separated from the air in the fork, which can lead to less precisely controlled damping when the two materials mix -become an emulsion - under more extreme use. Not having the damping oil under any positive pressure - as it is in a sealed damper - can also lead to loss of damping control due to cavitation, though this is rare. Solo Air spring

Finally, the SID SL looks like another OEM fork, but this one gets a Rush XC damper with a DebonAir air spring. This fork gets the same seals and fluid as the rest of the range. The granting of a best price is not combinable with other promotions (e.g. "free articles) from Bike-Discount.The ZEB Select+ shares many features with the flagship ZEB, including the DebonAir+ air spring, Charger 3 RC2 damper and Pressure Relief Valves, but it misses out on the vibration-damping ButterCups and machined crown. Coil spring on TK 15X100 [A2] and TK [B1] and Silver TK [D1], air spring on Silver TK [C1] and Silver TK [D1] and Silver RL [D1] and RL 15X100 [A2] and RL [B1] and Gold RL [A5], DebonAir air spring on Gold RL [C1]. Then, there's the Pike Select+ that runs most of what the Ultimate gets but it drops the lightweight crown and Buttercups tech. This one looks to be OEM only and isn't available aftermarket. Rounding up the Pike range is the Pike base which comes with a Rush RC damper, DebonAir+ air spring and everything that we get on the Select model, including the opportunity to upgrade the fork to use Pressure Relief Valves. Like the Select+, this one looks like it's OEM only. Fixed rebound on TK 15X100 [A2] and TK [B1], adjustable rebound on Silver TK [C1] and Silver TK [D1], adjustable rebound and low speed compression on Silver RL [D1] and RL 15X100 [A2] and RL [B1] and Gold RL [A5] and Gold RL [C1].
