Fox Float RP23 Adaptive Logic Boost Valve rear shock review£379.00

Double whammy is a game changer

BikeRadar score5/5

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.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
