Product Description

Overview

Tame rough terrain and long gravel grinds with the MEROCA SS02 5-Link Air Suspension Stem. Building on a four-link foundation, this innovative design adds an extra pneumatic strut link for ultra-smooth compression and rebound. With 20mm of vertical travel, titanium-alloy pivot shafts, and interchangeable air springs (160N / 190N), it filters high-frequency vibration while maintaining rock-solid steering stability—even under hard braking.

Key Features

✅ 5-Link Pneumatic Design – Adds an upper link to the 4-link base, integrating an air strut for lubricated, fluid compression/rebound motion.

✅ Titanium Alloy Pivot Shafts – Four rotating axes use Ti-alloy for superior strength-to-weight ratio; lighter and more durable than steel.

✅ 20mm Suspension Travel – Vertical shock absorption smooths potholes, roots, and washboard without altering rider posture.

✅ Interchangeable Air Springs – Includes soft (160N) and firm (190N) air struts to match rider weight and terrain; easy swap for custom tune.

✅ Forged Aluminum Body – High-strength alloy construction withstands high-impact MTB/gravel abuse; rigid where it matters.

✅ Stable Braking Geometry – Up/down damping keeps steering angle consistent under hard braking—no nose-dive, more safety.

✅ Dual Colorways – Black / Silver finish to complement your cockpit aesthetic.

Why Choose MEROCA SS02?

Vibration Eraser – High-frequency chatter from washboard and gravel vanishes; hands and wrists stay fresh on long days.
Tuned To You – Swap between 160N (lighter riders/smooth trails) and 190N (heavier riders/aggressive terrain) in seconds.
Brake-Safe – Unlike traditional suspension stems that dive, the 5-link keeps your bar angle steady under braking loads.
Premium Build – Titanium pivots + forged alloy deliver pro-level rigidity and low weight (398g) for a suspending stem.

Installation & Tuning Notes

⚠️ Verify fork steerer = 28.6mm and handlebar = 31.8mm before ordering.

⚠️ Torque bolts per manufacturer spec (typically 4-6Nm on clamp, 5-7Nm on faceplate).

⚠️ Start with 160N strut for most riders; upgrade to 190N if bottom-out occurs on drops or heavy landings.

⚠️ Air strut pressure can be fine-tuned via valve; check sag (~20-25% of travel under static load).

⚠️ Regular cleaning of linkage pivots recommended for longevity.
