Why do you want it?

You are using an FSA SMR stem and you want to reduce your stack height without routing the cables through the stem.

What is it?

This new hose guide system replaces the stock guides that come with FSA's widely-used SMR stem. It includes a 5.5mm adapter and a hose tray.

It has the following features:
1. Reduces the stack height of the stock stem setup from 18mm to 5.5mm, which is the width of a hydraulic brake hose.
2. Maintains the capacity to accommodate 2 brake hoses and 2 shifter cables.
3. Is compatible with the commonly used FSA ACR split spacers and the FSA ACR headset system.
4. Fits on FSA ACR compatible headset dust covers.

This sits on top of your FSA ACR / SMR compatible dust cover. Depending on your bearing configuration additional stack reduction is possible through use of this compatible product: https://apbikesbespokebits.etsy.com/listing/1504224526

How is it Made?

These parts are printed in the USA on Commercial Grade HP Multi-Jet Fusion machines. Parts designed to hold preload are made using PA12GB. While this material costs over 2x more than traditional PA12 Nylon, the addition of the glass increases its strength under compression by 80% and in this application, eliminates creep. Given that SLS and MJF printed nylons are only 60%-70% of the density of the high-pressure injection-molded parts made by OEMs, this assures OEM level performance.
