Spring sold SEPARATELY Already up in the EWS top ten! How was the Fenix born?The Fenix stemmed from the idea of having a shock as efficient as a downhill shock with an integrated climb mode that stays totally independent from the other adjustments.Why go for a coil spring and not an air spring?When aiming at efficiency, we automatically go for a coil spring, due to its great sensitivity and its perfect linearity, it provides great sensitivity, improves the grip of the rear wheel and gives more support in the mid-stroke.The key elements: 100% CNC Alloy 7075 T6 made and anodized with a PTFE impregnation to reduce friction. Monobloc Shaft + eyelet = stiffer and stronger. A membrane is used to reduce friction and heat.viton Shaft seals for better heat resistance. VDP piston = better traction control. 3 independent compression circuits LS – MS – HS = perfect ground flattening. EVO FEATURES : Redesigned head for more compatibility for more frames New spring retainer >> it's now easy to change the shock strange without opening the shock New preload ring design In short, the Fenix delivers:+ grip+ control+ safety+ performance+ speed Shock weigt without spring : In 230 x 65 mm, 500 gr In 210 x 55mm, 490 gr As our shock absorbers are made-to-measure products, assembly is carried out at the time of the order. The usual processing time is therefore 7 to 10 days.
