Why We Like The RockShox SID Ultimate Flight Attendant 29in Boost Fork

Whether we are racing or just cruising the singletrack, the RockShox SID Ultimate Flight Attendant 29in Boost Fork brings us space-age tech and race-worthy performance. An upgraded DebonAir+ air spring rides high in its travel for more confidence and pedaling efficiency, and the Flight Attendant damper reads terrain and rider feedback to automatically select the best compression setting for maximum efficiency so we can worry about leaving the competition in the dust and not which fork setting we should be in. The SID Ultimate fork features 120mm of travel, is fitted with burly 35mm stanchions, and runs on the same battery as SRAM's AXS components for a cable-free setup and a cleaner cockpit.

Firmware Updated!

Familiarity:
I've used it several times

Thanks to the latest firmware this does not have to be paired with a shock for Auto mode to function!
