Acera M3000 ES300 Octalink 73mm Bottom Bracket 113mm (Ex-Demo / Ex-Display). This is an ex display bottom bracket which has been fitted but not ridden and the original packaging is missing. Please see image for exact parts included.
The Acera M3000 ES300 Octalink 73mm Bottom Bracket from Shimano is a splined bottom bracket for use with Shimano Octalink chainsets. It features a large oversized 22mm diameter hollow spindle that is made from cold forged chrome-moly pipe billet, which reduces weight and increases strength and rigidity. Thanks to the Octalink splined axle/crank arm interface you have a more rigid crank assembly compared to a square tapered spindle. The sealed cartridge bearing assembly runs on oversized ball bearings with maintenance-free, high efficiency rubber seals to keep dirt, mud and water out and keep you rolling for longer. Available in 73mm x 113mm, 118mm, 121mm or 126mm.
Ex-Display parts, accessories and clothing are items that have very slight imperfections or have picked up minor cosmetic marks in store, in storage or in transit. The vast majority of Ex-Demo items will have had minimal usage only, but individual listings and images will make this clear. On rare occasions parts are missing and we would have been unable to source the exact original fittings, but with some suitable replacements from your spares or a reputable hardware supplier, these could be restored to full working condition. Please read the defects description and view the images for full details on each item. These items are only available for online mail order purchase or Click & Collect, and we are unable to supply these items internationally.
