The Sunlite Adjustable Top Mount Stem is a comfort-focused threadless stem designed to help riders quickly dial in handlebar height and reach without swapping fixed stems. Its top-mount design allows for easy angle changes from flat to upright, making it ideal for commuters, cruisers, hybrids, and recreational bikes. This version features a 110mm extension and fits standard 1-1/8" threadless forks while accommodating both 25.4mm and 31.8mm handlebars using included shims. Key Functional Details 110mm stem length Adjustable angle from 0° to 60° Top-mount adjustable threadless design Forged alloy construction Universal bar clamp fits 25.4mm or 31.8mm handlebars (shims included) Fits 1-1/8" threadless fork steerers Black finish Compatibility & Technical Notes Fork diameter: 1-1/8" threadless only Handlebar clamp: 25.4mm or 31.8mm with included shims Extension length: 110mm Angle adjustment range: 0°–60° Designed for road, hybrid, cruiser, and light MTB applications Not intended for aggressive trail riding, jumping, or racing Service / Ownership Context This stem is intended for fit adjustment and rider comfort. Once your preferred angle is set, all bolts should be evenly torqued and checked after the first few rides. Adjustable stems provide flexibility in riding position but are naturally less rigid than fixed stems. Fit & Use Signals Good Fit: Commuters, cruisers, hybrids, comfort MTB builds, riders needing bar height or reach adjustment. Not A Fit: Performance road bikes, aggressive trail bikes, or riders seeking maximum cockpit stiffness. Top-mount version gives easier access for angle changes. 110mm is mid-range reach — longer than comfort stems, shorter than race setups. Use the included shims — never clamp undersized bars directly. Expect slightly more flex than fixed stems. Set angle first, then align bars, then torque faceplate evenly. Not for jumps or hard trail riding. Best for riders experimenting with fit before committing to fixed geometry. Most installs fail from uneven bolt torque. Recheck after first ride.
