Surly Bicycles

We named this tire for our friend Nate, who is also quite large and aggressive. This tire has a shred-your-face-off, run-over-anything, kung fu grip knobby tread pattern. The casing is round and supple. Tall, widely-spaced knobs are siped for added grip and compliance. The knobs’ wide spacing means they dig deep and still shed the crap you’re riding through. The tread wraps a little around the sides of the tire, providing good knob contour even on very wide rims, which in turn allows good off-camber traction. Similar to our beer preferences, Nate is available in black and tan. - Folding bead - Max pressure: 30psi

Surly's Open Bar Handlebar is the go-to option for a good time. It features lots of space for grips, shifters, brake levers, or any combination of the a fore mentioned. The swept-back angle is comfortable for your wrists, and the stout chromoly construction is durable yet compliant. It's at home on bike paths or neighborhood cruises, and at an ominous 666mm, it's even wide enough to tackle some singletrack.

When you're out on a ride the last thing you want is to be limited by your tires in any way. Surly's ExtraTerrestrial tires were designed to let you ride without limits by following a simple tenet for tire design: make 'em high-volume and kick-ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off road touring tire that shines on hard pack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won't bog you down on smooth or hard surfaces. It's made to be durable and versatile and is at home on tour or on the trail. - Bead Seat Diameter: 559mm - Casing: 60tpi, tubeless-ready bead (928g)

Edna’s unique tread pattern has enough lug to provide bite on the loose stuff and a tight center tread that doesn’t drag on the hard. Add in a 4.3” footprint and you have enough traction and float to ride wherever and whenever you damn well please. - Folding bead - Casing: 60 TPI - Max pressure: 30psi - Weight: 1330g

The Surly Little Dummy Bag is a 15L sling-style bag designed to work with your standard rear rack and help you carry grocery bags, fishing poles, and other oddly shaped ephemera. Unlike traditional panniers that clip on and off real fast, we wanted a cargo solution that you could leave mounted to your bike when you're off playing laser tag. The idea is you just throw your backpack or whatever in there, turn the cranks awhile, and then pull out your gear when you've arrived. Quite slick. You can still scatter schoolbooks and loose cans of tuna inside the Little Dummy if you want, but the bag-within-a-bag method makes unpacking quicker. Use the system of daisy chains and One-Wrap straps to secure baguettes, flutes, and other stuff that might stick out. Cinch the side straps to further stabilize your load. And for extra credit, use your favorite Surly Whip Lash or Junk Strap to make your setup work the way you want. There's also a small zippered compartment inside the bag, if you're into pockets. Oh, and we should also probably mention that the bag's 1680D nylon main body and 400D nylon liner are bluesign Approved. So are the buckles and other hardware. That means the materials are sustainably produced to have the lowest possible impact on humanoids and our environment. Compatible with most standard rear racks, the Surly Little Dummy Bag is a sling-style bag designed to help riders haul big awkward items more easily. Secure your backpack, groceries, or camping gear inside the sling when it's time to ride. When you've arrived at your destination, quickly grab your stuff and leave the Little Dummy Bag mounted to your bike. You're unstoppable now. - A system of daisy chains and One-Wrap straps can be used to secure large, odd-shaped items - Interior zipper pocket - 25-lb. bag capacity. Consult your rack's weight limitations - 15L total volume

Our family of Dirt Wizards is highly-focused – one might even say spellbound – on providing traction and control on the kinds of surfaces where nary traction nor control are to be found.

Designed to work on 50mm rims, Dirt Wizards are tall and wide, providing next-level traction and cushioning. The casings have been designed to be flexible and responsive, yet durable and supportive. Minimum rim size for these naughty little wizards is a 35mm outer rim width. - Folding bead - Casing: 60 TPI - Max pressure: 30psi

This is Bud, a front-specific 4.8" tire designed for 559mm (“26 inch”) rims.

Bud’s aggressive mud- and snow-shedding tread is characterized by tall (7mm), siped knobs, arranged in a pattern ideal for the unique requirements of steering and braking. A supple, durable 120tpi casing with folding Kevlar bead conforms well to ground surfaces of all types. - Folding bead - Casing: 120 TPI - Max pressure: 30psi - Weight: 1600g

Surly's Stainless Steel Chainrings last longer than their aluminum brethern because the 304 grade metal they use is 35% stronger. The rings aren't pinned or ramped so when one side starts to wear you can flip it around and pedal some more! They work great with singlespeed, fixed, and 1x9 applications, and the teeth are 2.1mm thick so they work well with 9-speed chains.

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.

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.

The Terminal Bar blends cruiser-style comfort with off-road touring performance. Able to run with a 40mm drop or rise, its swept-back design makes it great for long rides on rough, technical terrain. - 22.2mm diameter grip area; good to go for MTB shifters, brake levers, and grips - 34 degree backsweep with a 40mm + / - rise
