Most of you don’t need the cargo capacity to land a helicopter on your rack. Sometimes, all you want to do is grab a sixer from the beer store on the way home or pick up a nice bouquet of flowers. For whatever the situation dictates, we offer the 8-Pack Rack. The 8-Pack Rack is a solid pedestal upon which you may rest a handlebar bag, grocery bag, minaudière, satchel…or whatever you use to carry your bowling ball around. The 8-Pack Rack attaches to most forks with mid-blade and crown eyelets. It uses stainless steel hardware (handily housed in a reusable Surly Tool Bag), and has the characteristic durability, versatility, and repairability all Surly products are known for. The 8-Pack Rack has lots of barrel braze-ons, so you can customize your cargo tie-downs…or just bolt on as many lights as you can.

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.

Surly made these handy plates for use with either the Long Haul or Disc Trucker frames, and only the Long Haul and Disc Trucker frames. They are to be used with a bicycle kickstand to keep your bicycle upright while not moving as if by magic. The plates consist of two halves that, when clamped on your frame in conjunction with a kickstand, protect your chainstays from hamfisting by sandwiching the frame between the plates. Have you ever eaten a hamfist sandwich? They taste terrible, so avoid them like the plague. - Compatible with 2019 and older Long Haul and Disc Trucker frames

That's why Surly made a chainring guard to fit O.D. cranks. It is made of aluminum and will take the hit for your chainring. It comes in 5 bolt, 94mm BCD and was designed to protect 22t – 30t rings.

An issue many people ran into when they began using 1x setups was chain retention with the front chainring. In the beginning of the 1x movement, many companies dealt with this by using aftermarket chain keepers that somehow bolted to the frame. Many people discovered that using a narrow-wide chainring in conjunction with some type of 'clutch' rear derailleur helped abate or eliminate these chain-jumping issues. Narrow-wide rings use alternating tooth profiles that more positively engage the chain and help control a deflecting chain in bumpy conditions. Your friends at Surly have partnered with SRAM to bring you stainless steel X-Sync chainrings. Stainless Steel is durable. This durability is pretty useful when you're talking about the one ring that is bearing the brunt of all your miles.
