Spruce-up a well-loved Dummy bag with replacement parts from Surly.

Surly Rim Strips have one job and they do it well. They cover the cutouts in your rim and — if you're running a tube — they protect it from spoke heads and other sharp matter (okay, so maybe they have TWO jobs but they do them both really well.) Rim strips are crucial and should be used with all Surly rims. Ours come in an array of colors so you can really "express yourself." Surly Rim strips are available in two different materials: PVC and Nylon. PVC is great if you plan on only running tubes. However, if there's any part of you that wants to try this tubeless thing you've been hearing about, Nylon strips are just the ticket. They're thinner and offer minimal stretch so they stay put and lay nicely inside the rim to provide a secure seal. Plus, they're lighter which we all know means you'll go faster… maybe.

Rim strips designed for Surly Rabbit Hole 26+. - Rim Strip Width (mm): 38 mm - Adhesive: No - Material: PVC - Wheel Size: 26" - Tire Diameter: 26"

Surly Rim Strips have one job and they do it well. The 58mm nylon rim strip is purpose-built for the Clown Royal Rim, and Moonlander bike.

The Loop Junk Strap is the same 120cm woven nylon strap with a stainless steel buckle that Surly's regular junk strap is. The Loop Style Junk Strap, however, has a loop sewn at each end of the strap so you can wrap them around small diameter tubing like that used for racks and handlebars. They secure in the middle with the stainless steel buckle. Surly made these Loop Style Junk Straps because it offers another method for those wanting to secure cargo to their racks and or bikes. Junk Straps of any kind are useful in many different situations so toss a few in your backpack and always be ready to tie something to anything else. - For general tie down use - 42" loop strap, plus 8" closure buckle strap

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 2.2 - 2.3mm thick so they work well with wider chains.

Hi, I'm the Surly Lightweight Neck Toob. You might remember me from such films as “It's Cold! Don't Forget Your Neck Toob!" and “Look At This Thing, It Came From a Sheep!" Right now you might be thinking, “But Surly, I already have a Neck Gaiter from you guys. Do I really need a Neck Toob?" And the answer is maybe. Unlike the existing Neck Gaiter, which is made of a light inner layer and a midweight outer layer, I'm made of two lightweight layers. For those days when it's too chilly to leave your face and neck exposed but not cold enough for the full-blown Gaiter, I try to provide a nice, moisture-wicking alternative. I'm sized to fit most necks, and I can be worn a bunch of different ways. Thanks for tuning in, we'll see you next time. Your Friend, The Surly Neck Toob

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.

The Surly Truck Stop Handlebar combines the benefits of a drop bar with those of a riser bar.

When you’re out on a ride the last thing you want is to be limited by your tires in any way. Our ExtraTerrestrial Tires were designed to let you ride without limits by simply following the only tenets we have for tire design: they’re high volume and they kick ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off-road touring tire that shines on hardpack 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 tread blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won’t bog you down on smooth or hard surfaces. - Folding bead - Casing: 60 TPI - Recommended rim width: 23 – 30mm

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.

In today’s fast-paced world of riseless flat bars and far-too-aggressive-for-our-liking cockpits, Surly harkens back to simpler times. They wanted a handlebar that would suffice for a relaxed cruise to a favorite windowless bar, but would also be suitable should a person decide to take the long way home. The Sunrise Bar is a cruiser bar, a trail bar, and a BMX bar all rolled into one. It has a 22.2mm clamp diameter, but Surly included some Problem Solvers shims so you can mount it up to your fancy 31.8mm stem. Material: CroMoly steel Clamp diameter: 22.2mm; Includes shims for 31.8mm clamp Width: 820mm; Can be cut to 720mm Rise: 83mm Sweep Angle: 14.7 degree backsweep, 6.7 degree upsweep Weight: 778g including shims Color: Black

We set out to make a handlebar that’s upright, durable, and capable of resurrecting a parts-bin bike or transforming a newer slice of steel into something more. What we came up with is the Sunset Bar. We liken it to its sibling, the Sunrise Bar, with BMX-inspired style and vertical posture. Procure one yourself for a fresh take on front end grip. - Constructed with 4130 Chromoly Custom-Butted Steel tubing for enhanced strength and comfort, and finished in an anti-rust Black ED coat for longevity - Brings comfort, style, and durability by fitting a more upright position with 110mm of rise, 22-degree backsweep, and 14-degree upsweep - Adds height to frames with short steerer tubes or headtubes - Tested to comply with ASTM 3 and ISO Mountain Standards for rowdy trail riding and beyond Specifications: Material: Post-weld heat-treated Chromoly Steel Clamp Diameter: 22.2mm; Includes shims for 31.8mm clamp Width: 820mm Rise: 110mm Sweep Angle: 22 degree backsweep, 14 degree upsweep Weight: 827g including shims Color: Black
