When the latest Rockshox SID was introduced for model year 2017, they upped the stiffness and performance for their lightweight cross country fork. In the process, they capped the travel at 100mm, leaning on the Reba and Revelation to handle mid-travel trail bikes. Now, they’ve incorporated their new DebonAir system, the latest Charger 2 damper, and added several 120mm travel options.
These internal updates all go into the latest SID chassis. They may look the same, but the changes should make them more plush and give trail bikes a new lightweight weapon…
Updated SID tech
The biggest change is the inclusion of their new DebonAir. The video above provides an overview, and we covered it in detail when it debuted on the new Lyrik, Yari, Pike and Revelation. The gist of it is this: The internals are now smoother with new materials to reduce friction, and the negative chamber is larger thanks to ports that use the inside of the air shaft to create more volume. Hit that link for more info. The result should be better small bump compliance.
All three options also upgrade to the latest Charger 2 damper, but only the RL and RLC offer the 120mm travel…and only in 29er form. There’s no 120mm 27.5″ SID. The World Cup is limited to 100mm because the ultralight carbon crown and steerer assembly was designed specifically for the 80-100mm travel range…of which, there is now only a 100mm option. The other two models use their alloy crown and steerer, which they say is up to the task.
The forks also have their Dig Valve, which was introduced in 2013 as a damping-induced platform and updated for MY2017. Essentially, it restricts compression flow on small, slow hits to keep the fork riding higher in its travel and ready for a bigger, harder hit, at which point it speeds up flow rate to handle the impact.
2019 Rockshox SID World Cup
Full specs are shown in the graphic at bottom of the post, but here’s the quick and dirty for each model, starting with the top of the line SID World Cup:
- 100mm travel
- 27.5 or 29er, Boost only
- 1,537g claimed weight
- 2-Position Open/Locked with separate compression adjustment
- TwistLoc and OneLoc remote lockout compatible
- $999 – 1079 // €1109 – 1199* // £989 – 1069* (*includes VAT)
2019 Rockshox SID RLC/RL
Both the SID RLC and RL share all the same updates, with the only key difference being the addition of the compression adjustment knob on the lockout. The RLC lets you adjust the range of compression damping, but the RL is simply locked or open.
- 100mm travel (27.5″ & 29″), 120mm (29″ only)
- 27.5 or 29er, Boost only
- External rebound adjustment
- TwistLoc and OneLoc remote lockout compatible
- SID RLC:
- 1,537g claimed weight
- 2-Position Open/Locked with separate compression adjustment
- $779 – 849 // €869 – 939* // £769 – 839* (*includes VAT)
- Claimed weight: 1,618-1,637g
- SID RL:
- 2-Position Open/Locked
- $559 – 669 // €669 – 739* // £589 – 659* (*includes VAT)
- Claimed weight: 1,596-1,615g
- 1,537g claimed weight
All three forks will be available in May 2018.
