RockShox SID Ultimate Race Day 3P Remote 29" Suspension Fork D1

The RockShox SID Ultimate Race Day 3P Remote 29" Suspension Fork D1 is RockShox's lightest cross-country race fork, built around a 35mm chassis that holds a line under hard cornering without adding unnecessary weight. At 1,480 grams in this 120mm-travel configuration, it's built for racers who want every gram to count without giving up stiffness on technical singletrack.

The Charger Race Day 2 damper is RockShox's lightest production damper, offering three compression positions — Open, Pedal, and a rock-solid Lock — adjustable either at the crown or through a bar-mounted remote (cable pull 7mm+7mm, sold separately) for switching without taking a hand off the bar. The DebonAir+ air spring is tuned for small-bump sensitivity off the top with tunable mid-stroke support via Bottomless Tokens, so racers can dial in a setup that matches their terrain without sacrificing that supple initial feel.

Running on a 15x110mm BOOST axle with bolt-in Torque Cap adapters and a 1.5" tapered steerer, the SID Ultimate is built strictly for XC and marathon racing — it is not approved for e-bike use. It's available in Electric Red or Gloss Black and suits racers who want a lightweight, remote-ready fork without the added cost of Flight Attendant's automatic suspension.
