This is a ground up redesign of the inherently flawed linkage that comes on the Altis Sigma. The factory linkage has bearings that are too small, sleeves that are too thin, and a l ack of dust seals to keep the bearings clean and alive. My stock linkage failed within 100 miles of woods riding. Cracked sleeves, ruined bearings and more. This new system has several benefits over what comes on the bike. Fits 2024 and 2025 models. larger, higher quality bearings for increased load capacity and longer life. dual lip spring loaded dust seals to keep grease in and dirt/ water out. larger high precision hardened and ground sleeves new hardened and ground bearing sleeve for the frame that replaces the stock soft mild steel sleeve. 4 position ride height adjustment with up to 1 inch higher / lower setting. machined 6061, 7075 aluminum construction. Laser cut 304 stainless adjuster keys. M10 grade 10.8 JIS pivot bolts replace the mis matched m8 and m12 that come on the bike. Linkage comes pre greased and ready to be installed. Show more
