The three-position compression system — Open, Pedal, and Lock — adjusts automatically using a sensor suite that reads rider inputs and terrain in real time. No buttons to push mid-ride. The new Adaptive Ride Dynamics algorithm takes this further, learning rider preferences over time to make increasingly personalized decisions about suspension position. For hardtail builds, a fork-only mode is available; Auto Mode is also customizable to disable the Pedal or Lock position if preferred.\u003c\/p\u003e\n\n  \u003cp\u003eThe chassis is built around 35mm tapered aluminum upper tubes — RockShox's chosen balance of stiffness and weight for modern XC geometry — with a machined crown to shave grams without sacrificing structure. DebonAir+ spring provides improved small-bump sensitivity at the top of travel with tunable mid-stroke support via volume tokens. The system runs cable-free on the shared SRAM AXS battery ecosystem and is rated IPX7 waterproof. Maxima Plush Dynamic Suspension Lube comes pre-installed to reduce friction and extend service intervals.\u003c\/p\u003e\n\n  \u003ch3\u003eSpecs at a Glance\u003c\/h3\u003e\n  \u003cul class=\"specs_at_a_glance\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWheel size:\u003c\/strong\u003e 29\"\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTravel:\u003c\/strong\u003e 120mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDamper:\u003c\/strong\u003e Charger Race Day 2 Flight Attendant (3-position: Open\/Pedal\/Lock, auto-controlled)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpring:\u003c\/strong\u003e DebonAir+\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChassis:\u003c\/strong\u003e 35mm tapered aluminum upper tubes, machined crown\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSteerer:\u003c\/strong\u003e 1.5\" tapered\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAxle:\u003c\/strong\u003e 15x110mm BOOST\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFork offset:\u003c\/strong\u003e 44mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1,624g (120mm, with Maxle Stealth, no battery)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMax tire width:\u003c\/strong\u003e 66mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMax rotor:\u003c\/strong\u003e 220mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVolume tokens:\u003c\/strong\u003e 0\/3 or 1\/3\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWaterproof rating:\u003c\/strong\u003e IPX7\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColor at RA Cycles:\u003c\/strong\u003e Electric Red\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"RockShox","offers":[{"title":"Electric Red \/ 120mm","offer_id":45407670665260,"sku":"00.4021.283.002","price":1599.0,"currency_code":"USD","in_stock":true},{"title":"Gloss Black \/ 120mm","offer_id":45555069747244,"sku":"00.4021.283.000","price":1599.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ROCK-SHOX-SID-ULTIMATE-FLIGHT-ATTENDANT-RACE-DAY-ELECTRIC-RED_0d7f47f8-410d-44ab-bd35-672dad9f7784.jpg?v=1774458161","url":"https:\/\/racycles.com\/es\/products\/rockshox-sid-ultimate-flight-attendant-race-day-3p-29-suspension-fork-d2","provider":"RA Cycles","version":"1.0","type":"link"}
