SGS-400-OS · Oversize Computer Mount · 27.2 / 31.8 / 35.0mm · 3 Devices · Aluminum
Minoura SGS-400-OS Computer Mount
Mount up to three accessories on an oversize bar or seatpost — the OS variant of the SGS-400 clamps to 27.2mm, 31.8mm, and 35.0mm diameters without adapters.
The Minoura SGS-400-OS is the oversize variant of the SGS-400 accessory mount — fitting the larger bar and seatpost diameters common on modern MTB and e-bike builds. It holds up to three devices and clamps directly to 27.2mm seatposts, 31.8mm oversize bars, and 35.0mm wide bars without needing shims or adapters. Same price as the STD model with the same aluminum LW-clamp construction — choose the OS when the bar or post is 31.8mm or larger.
Highlights
Three device positions — bar or seatpost
Mounts up to three accessories in a single clamp — GPS computer, light, camera, or any compatible accessory. Works on both handlebars and seatposts, giving flexibility in where devices are positioned on the bike.
Oversize clamp — 27.2 / 31.8 / 35.0mm
Fits the bar and seatpost diameters used on modern MTB and e-bike builds. 31.8mm is the standard oversize bar diameter; 35.0mm is used on many trail and enduro bars. 27.2mm covers the most common round seatpost size. No shims needed for any of the three.
SGS-400-STD also available — smaller bars
If the bar or post diameter is 22.2mm, 25.4mm, or 28.6mm, the SGS-400-STD (#160673-01) is the correct choice — same price, same design, smaller clamp range and two device positions.
