Grand Bois Decaleur for Aluminum Stems

Grand Bois Decaleur for Aluminum Stems (Discontinued)


A decaleur attaches the handlebar bag securely, so it does not move around as you ride. It also keeps the bag clear of the handlebars, so you can use the “tops” hand position without having to wiggle your hands between bag and handlebars.

The decaleur consists of two parts: One attaches to the stem, the other to the bag. Pins on the bag attachment slide into the tubes on the stem attachment with a precise friction fit. This means they don’t rattle or jump out. To remove the bag, you simply pull it upward, and the bag comes off the bike.

The Grand Bois decaleur now also is available in models that fit many aluminum stems, provided they have a single, horizontal handlebar clamp bolt. The decaleur replaces the handlebar clamp bolt. On stems where the bolt threads directly into the aluminum, the threads must be removed by reaming with a drill. (This does not weaken the stem, as the threads do not add strength.) The handlebar clamp is tightened with a nut that goes behind the handlebar clamp. (If your stem does not have a flat surface there, you will have to create one with a file.)

Made by Nitto, fillet-brazed steel, triple-plated (copper, nickel chrome).

Made in the Japan. 10 year warranty.

This decaleur has been discontinued. Click here for the Compass Decaleur.

Compass Bicycles modifies each Grand Bois decaleur to make sure the bag is securely attached to the decaleur and does not jump out under normal riding conditions. To remove the bag, you simply pull it upward, and the bag comes off the bike.

There are two models: this one (“for Aluminum Stems”) is designed to fit many classic stems, the other includes special parts to facilitate installation on Nitto NP and Pearl stems.

Note: The decaleur does not replace a rack: The bag still needs to be supported from below.

    • Requires modifying some stems (reaming out threaded hole)
    • 120 g (with bag attachment and bolts)
