<!--ProdInc[300279367]/Mall:[backcountry_US]-->From toeing the line at the local XC circuit to all-day downcountry epic, the RockShox SID Ultimate Race Day 29in OneLoc Boost Fork has our front suspension needs covered. RockShox chose 35mm stanchions for the perfect balance of stiffness and weight to handle the demands of modern cross-country bikes. 120mm of responsive travel and a 44mm offset built around 29-inch wheels give this fork incredible handling as we bob and weave through technical rock gardens, while an XC-tuned DebonAir air spring rides higher in the travel for confidence-inspiring control. The ultralight Charger Race Day Damper gives us just enough adjustment to handle varying conditions and is combined with the OneLoc remote creating a rock-solid lockout for ultra-efficient climbing. <h3>Details</h3> Short-travel 29er fork for high-speed cross-country riding 35mm stanchions offer high torsional stability for techy trails 120mm of travel rolls smoothly over rocks and roots DebonAir air spring is specifically tuned for high-speed XC OneLoc remote lets us lockout the fork without reaching down Charger Race Day damper allows for efficient climbing and sprinting SKF seals provide ultra-low friction for an unmatched suspension feel Item #RSXB073 <h3>Tech Specs</h3> Travel : 120mm Stanchion Material : aluminum Wheel Size : 29in Steer Tube Diameter : 1.5in tapered Stanchion Diameter : 35mm Axle To Crown : 531mm Rake : 44mm Spring Type : DebonAir Damper : Charger Race Day Adjustability : 2-position OneLoc remote Lockout : yes Axle : 15 x 110mm Boost, Maxle Stealth Brake Compatibility : post-mount disc Rotor Compatibility : 180 - 220mm Inclu <a href=''https://www.backcountry.com/rockshox-sid-ultimate-race-day-29in-oneloc-boost-fork?RSXB073-BLU'' target=_blank><img src=''https://www.antpop.co.kr/antMain/AntImgView?CustID=jellymom2&MallKind=US&MallID=backcountry&ProdInc=300279367&MallIDEncodeYes=0&SiteName=PostSelf'' width=''100px'' height=''20px'' border=0></a>
