FOX Racing Shox

Frequently Asked Questions

• How do I choose between the FLOAT SL, FLOAT X, and Float X2 for my riding?

  FLOAT SL is tuned for XC racing where minimal weight and quick efficiency matter, FLOAT X is a versatile air shock aimed at aggressive trail to all‑mountain/enduro use, and Float X2 is a high‑tunability, trunnion‑mount shock built for enduro/DH where plush mid‑stroke and large‑hit control are priorities. Match the model to your discipline, then confirm eye‑to‑eye/stroke and mount type to ensure fit before tuning.
• What eye‑to‑eye and stroke dimensions and mount types should I check before buying a FOX rear shock?

  The first checks are the frame’s required eye‑to‑eye length and stroke and whether your frame uses a trunnion or standard eyelet mount—mismatching these causes fit and compression issues. Also confirm the intended wheel size and leverage curve for your frame, then use FOX spec sheets and your frame manual to pick the correct shock.
• How do GRIP X2, GRIP2, and FIT4 dampers differ, and which should I choose?

  GRIP X2 offers independent high‑ and low‑speed compression plus rebound for maximum tunability and support on enduro/DH bikes, while GRIP2 (and FIT4 on some forks) provide high‑quality external compression and rebound adjustment with simpler operation and smooth feel for trail/all‑mountain riding. Choose GRIP X2 if you need precise control over big‑hit behavior and mid‑stroke support; choose GRIP2/FIT4 for lighter, easy‑to‑tune performance on trail bikes.
• What’s the proper sag and volume spacer setup for a FOX fork or shock?

  Start with 20–30% sag of total travel depending on discipline (lower for XC, higher for enduro/DH), set spring pressure to hit that sag while mounted with gear, and then fine‑tune mid‑stroke and bottom‑out with EVOL air volume spacers (add spacers to firm the mid‑stroke, remove to increase progression). Rebound and damping should be adjusted after sag is correct; use FOX setup guides or videos for step‑by‑step PSI and spacer recommendations.
• How do the Fox 36 and Fox 38 forks compare, and which should I pick for my trails?

  The Fox 36 bridges trail to enduro with roughly 150–160mm of travel for riders who want a mix of pedaling efficiency and rough‑trail capability, whereas the Fox 38 is stiffer and aimed at enduro/DH or bike‑park riding with ~160–180mm of travel for the roughest terrain. Pick a 36 for lighter, more playful trail bikes and a 38 when you prioritize stiffness, control, and descending performance on technical, high‑speed lines.
