Surly's Dummy Deck provides a light, durable platform for cargo bikes, built to Xtracycle's Longtail standard — including the Big Dummy, of course. The Dummy Deck is stamped from 4mm-thick aluminum, chosen for its strength, durability, and recyclability, and it bolts directly to Surly Dummy Rails to stiffen and stabilize the whole system (it's also compatible with Xtracycle V-racks by using Xtracycle's SuperHooks). It features cut-outs for routing straps and cordage, a mounting hole for a rear light bracket, accessory-mounting holes, and countersunk holes for SuperHook hardware.

Dummy Rails support Dummy Bags on your Big Dummy cargo bike, and Surly's Dummy Deck bolts directly to them, stiffening the whole system for a more stable load. Dummy Rails are made of light, strong aluminum and were designed in conjunction with the Dummy Deck and Dummy Bags; each component works best when used with the others. Like all Surly products, they've built in lots of useful details. For example, the deck-attachment bosses stick up from the rails to create space between the deck and rails, providing windows to route tie-down straps and cordage; and threaded bottle cage bosses located at the rear of each rail provide mounting locations for accessories: bottle cages of course, or lights, cameras, pumps, flags, horns, light saber scabbards, disco balls, spittoons, cornucopias, etc. Dummy Rails will work with cargo frames (including the Surly Big Dummy) built around Xtracycle's longtail standards.

If you use an ORTLIEB Back-Roller, Bike-Packer, or Velo-Shopper for your ride to work, you may want to consider the advantages of the Commuter Insert. You pack the Commuter Insert at home – with your laptop, lunchbox, documents, water bottle, pens, smartphone, change of shoes, etc. – and then simply insert it into your pannier. The advantage is that everything stays well-organized, nothing goes mysteriously missing and nothing hides in the depths of your bag. And so you save time and avoid those nervous moments of uncertainty. While the Commuter Insert is ideal for commuters, it can also be a faithful companion to anyone who transports gear from any point A to any point B. The Commuter Insert is made of lightweight, durable nylon fabric. A padded compartment for your laptop or tablet is located directly under the handle. There is a separate pen compartment and two compartments for your smartphone and money, including an integrated key chain. The large inside compartment offers plenty of space for provisions and a change of clothes. FEATURES: - Stable and tip-resistant even when empty - Two side mounts for water bottles, etc. - Flat mesh pocket (ideal for a bike lock) - Foam padding on the sides and bottom - Ideal for use with all ORTLIEB Back-Rollers, Bike-Packers and Velo-Shoppers - Permits access to the inside pocket of your bike pannier
