Fox Float RP23 Kashima rear shock

BikeRadar verdict

100.0 out of 5 stars

"A whole new standard in sensitivity, accuracy, adjustability and speed boosting control"

Fox debuted their slick, gold-coloured Kashima surface coating on aftermarket forks last year. Now it’s been extended to their rear shock line. Their new Kashima coated 'Adaptive Logic' shocks set a new gold standard for small bump sensitivity and control.

Reduced stiction means we had to go up a whole level of compression tune (from light to medium) compared to last year’s shock to stop it being too mobile. Small bump suppleness and traction consistency are phenomenal and sensitivity and accuracy at any point in the stroke are amazing.

The new Adaptive Logic reverses the previous RP23 logic to give a pre-set ProPedal low-speed compression threshold, with three subtly different levels of damping in the open position. The net effect is softness for tyre ripping traction yet with amazing drive and flow through rolling terrain. It also delivers a solid cornering platform for berm rich trails, and despite the super-plush start we only bottomed it out once off our biggest test drop.

The Float also comes in a large range of eye-to-eye and stroke sizes (including ultra short cross-country sizes). The Kashima technology hasn’t added much cost either. Unfortunately for all their peers, Fox haven't just moved the goalposts but changed the game with their Kashima smoothness / Adaptive Logic control double whammy that makes average bikes feel like the best in class.
