SID has lost the RockShox race limelight to the radical RS-1 but it's still the lightest, easiest to tune and most cost effective speed fork in the SRAM suspension arsenal.
The RCT3 fork doesn't get the carbon fibre crown steerer unit of the SID XX World Cup fork, which means it weighs just under 1600g rather than just under 1500g, but saves you 290F. While fore and aft twang under braking and some steering softness is noticeable from the hollow ended lowers and 32mm stanchions in 29er format it's comparable with similar weight race forks.
The single chamber, automatic negative spring setting Solo Air spring makes setting up for easier than the old DIY adjustable positive and negative spring SIDs. There's a reasonably accurate pressure chart and a sag display ladder on the fork to get you in the ballpark too.
The RCT3 damper cartridge gives fully Open, stubborn start Threshold and fully Locked settings with the fick of the fork top lever, Dnd low speed coppression is also independently adjustable. That gives a full range of tuning options depending on whether you want a super-eficient only-moves-in-emergencies feel or something more pliable for boosting traction and comfort. The addition of the Charger damper derived Dig Valve means the previously rubbery feeling mid stroke now adds real control and confidence when you're trying to gain a gap on a descent. It's relentlessly reliable too and you get the seals and spares for your first DIY service included in the reasonable price.
