RockShox SID Ultimate Race Day 2P Remote 29" Suspension Fork D1

RockShox SID Ultimate Race Day 2P Remote 29" Suspension Fork D1 is built for cross-country racing, where every gram and every second of lockout speed counts. It's built around a 35mm chassis that RockShox designed to balance weight savings with the rigidity you still want when you're railing a technical descent between climbs, and a machined crown shaves additional weight without giving up strength at the steerer.

The Charger Race Day 2 damper inside keeps things simple on purpose: a two-position compression switch that's either fully open or locked solid, rather than a range of climb-mode settings to fuss with mid-race. RockShox markets it as the lightest damper in its lineup, and the 2P Remote setup lets you flip between open and locked from the bar through a 10mm cable pull, using a compatible TwistLoc or OneLoc remote sold separately. DebonAir+ handles the air spring side, adding small-bump sensitivity and more tunable mid-stroke support than earlier SID air springs, with extra positive and negative air volume to back it up.

Set up with 120mm of travel, a 44mm offset, and a 15x110mm Boost front axle, this fork suits XC racers and marathon riders who want a lockout they can hit without thinking and a chassis that still holds a line when the course gets rough.
