Common Questions

What handlebar diameter and steerer size does this stem fit?
This stem fits 25.4mm handlebars and a 22.2mm (1") quill steerer tube with 180mm quill length. It is not compatible with 31.8mm bars or threadless steerers without a shim.
What material is the stem and how should I clean it?
The stem is die-cast aluminum alloy. Clean with a damp cloth and mild soap; avoid abrasive cleaners.
Does the stem come with bolts or a faceplate?
This is a one-piece quill stem with no removable faceplate. No mounting hardware is included. The handlebar clamp area has no teeth/serrations.
Is this stem suitable for a modern road bike?
No, it is designed for vintage or fixed-gear bikes with a 1" quill steerer and 25.4mm handlebars. Not for 1 1/8" threadless forks or 31.8mm bars.
How long does shipping take and where does it ship from?
Ships from China. Delivery typically takes 7-30 days depending on shipping tier. Checkout requires human approval due to cross-border shipment.
