Surly

Surly Stainless-Steel Chainring (110mm BCD)
$35.00 - $65.00
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.

A hollow axle lets you choose how to secure it to your dropouts. You have choice between the included fixing bolts or a quick release skewer (sold separately). And, that aforementioned chromoly axle is flex-free to take all the abuse you can dish out, and then some!
Surly Tall Socks
$30.00
That's right, Tall Socks. No fancy name here, it's the Surly way. What they lack in flash and flair, they make up in awesomeness. They're made from Merino wool for the perfect pairing of breathability and durability. They keep your feet comfortable in any temperature, even when wet, and they cover your shins. What more do you need?
Surly Logo T-Shirt
$30.00
Shirts are a color, sometimes it's black, or green, or red, or gray or one they haven't picked yet. Printed Surly logo on the front is a different color, usually black or white.
Surly Big Dummy Frameset
$1,099.00
Big Dummy is a long-tail cargo bike, which means that not only can you haul a serious amount of cargo, different accessories can be added to your Big Dummy frame and deck depending on what you want to carry. Being a dedicated single-piece frame, instead of an add-on to an existing bike, it's stiffer and resistant to torsional flex, which provides a better ride and longer lasting frame than long-tail add-ons. Like all Surly's frames, it's made of their size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you've come to love in a Surly, like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it's loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before. It's suitable to loaded as well as unloaded riding. Bags, deck, rails, and rail collars are all designed to improve on previous offerings and work together to make sure your stuff is transported with safety and stability. It's an unbending interface, which when you're carrying lots of cargo, is a good thing to have. Get creative, and get hauling. If you intend to carry a passenger on your Big Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. These are included with MY17 Big Dummy bikes and frames, as well as available AM for older Big Dummy bikes and frames (compatible with all generations of Big Dummy bikes/frames). In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. If you are planning to carry a child on your Big Dummy, Surly recommends the use of a child seat. They've tested the Maxxi Yepp seat. Yepp makes an adaptor that allows their seat to mount onto Surly's deck. It works well with the Big Dummy. At this time other child seats are not recommended and will void your warranty. Surly is testing other options. Note: keep in mind Big Dummy weight limits when carrying a passenger.
Surly Wool Pocket T-Shirt
$85.00
Who doesn't like t-shirts? Idiots, that's who. What's not to like? You can wear them all the hours of the day. They work equally well in the shower as they do in the pool. They function as both daywear and eveningwear. Surly tripled its functionality by adding a pocket. A POCKET!!! Now they've taken that infinitely versatile garment (it's the Cross Check of Clothes) and had it made out of (what Surly would call our their favorite material) merino wool (after steel and rubber, silly). In short, it's a t-shirt, it's wool, it's got a pocket (A POCKET!!), you wear it. Donzo.
Surly ECR Fork
$130.00
The ECR fork is much like the Ogre fork. Both are CroMoly 29er forks. Both work with frames designed for 80mm-travel suspension forks. Both feature 51mm I.S. disc caliper mounts, brake line guides, accommodations for a rack and fender, and 2 sets of cage mounts (one on each leg) that let you mount large size or standard water bottle cages. Both are designed to run just about any combination of parts and accessories you'd want on a fork and are finished in durable black powdercoat. The only real differences are 1) ECR is disc brake only, and 2) ECR's offset is 47mm, 5mm more than Ogre's. - Axle-to-crown: 468mm - Offset: 47mm - Steerer: 260mm, 1-1/8" straight - Tire Clearance: 29 x 3.0" - Weight: 3.1 lb (1.4kg) uncut
Surly Stainless-Steel Chainring (94mm BCD)
$35.00
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.
Surly Thru Axle
$30.00 - $33.00

Surly Disc Trucker Thru-Axle Fork
$175.00
Like its QR cousin, the Disc Trucker Thru-Axle Fork is designed to mount racks and fenders and haul your worldly possessions. It's also got modern touches like dynamo routing, compatibility with flat-mount disc brakes, and three-pack mounts on both fork blades to satisfy your deepest cargo desires. Captured 12mm thru-axles make tool-free removal and installation possible. Offered in 26" and 700c wheel sizes, the Thru-Axle fork clears 26 x 2.1" or 700c x 47mm tires. With a 1-1/8" steerer, it's powder-coated and constructed using the same Chromoly steel as all our other frames and forks. Why? Because we swore a blood oath to steel and we intend to keep it. Note: The Disc Trucker TA Fork is designed to pair best with second-generation Disc Trucker models—those first released in 2020. Defy this guidance at your own peril. 26 Inch - Axle-to-crown: 376mm - Offset: 45mm - Steerer: 42–54cm frames = 300mm, 1-1/8" straight - 56–62cm frames = 400mm, 1-1/8" straight - Tire Clearance: 26 x 2.1" (with or without fenders) 700c - Axle-to-crown: 390mm - Offset: 45mm - Steerer: 56–64cm frames = 350mm, 1-1/8" straight - Tire Clearance: 700c x 47mm (with or without fenders)

Surly Midnight Special 650b Fork
$175.00
This beauty here was designed alongside Surly's Midnight Special frame. In an effort to shed a few grams (it's for a road bike after all), they opted to utilize a unicrown design rather than a lugged one. In addition to the weight savings, it also looks really nice — don't you think? Like the Midnight Special frame, this fork is equipped with modern road standards like flat mount disc brakes and a 12 x 100mm thru-axle. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - 100% CroMoly construction, fully brazed crown - Mid-blade thru-blade eyelets - Rack and fender eyelets at the dropout - 12 x 100mm thru-axle - Clearance for 27.5 x 2.32 or 700c x 42mm tires
Surly Midnight Special Road Fork
$175.00
This beaut here was designed alongside our Midnight Special Frame. In an effort to shed a few grams (it's for a road bike after all), we opted to utilize a unicrown design rather than a lugged one. In addition to the weight savings, it also looks really nice—don't you think? Now, we don't throw the phrase "future-proof" around lightly, so we won't use it here either. What we will say is that, like the Midnight Special Frame, this fork is equipped with modern road standards like flat mount disc brakes and a 100mm x 12mm thru-axle. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - Axle-to-crown: 400mm - Steerer: 350mm, 1-1/8" straight - Tire Clearance: 27.5" x 2.32" or 700c x 42mm (27.5 x 1.95" or 700c x 38mm w/fenders) - Weight: 1254g
Surly Straggle-Check Frame Bag
$195.00
Dubbed 'Straggle-Check' frame bags, these bags are designed to fit both 700c and 650b Straggler and 700c Cross Check frames. Size up one size on your bag if you've got a 650b Straggler frame and voila, it fits. These are handmade by Revelate Designs in the U.S., made of Dimension Polyant VX 21 polyurethane coated fabric. It's durable, rip resistant, tightly woven and laminated to make it highly water resistant but not fully waterproof…. Revelate advises using stuff sacks inside (such as the one in which our bags are packaged) if you risk riding in extended downpours or underwater. Surly's Straggle-Check frame bags (as well as their mountain bags) are now using a ladder strap system, which allows greater flexibility in how you attach the bag to your frame. The ladder straps let you customize the fit and placement of the mounting straps so if you have some weird contraption clamped to your frame tubes like a chain keeper, cable pulley, or some trinket grandma gave you, it won't interfere with the mounting straps on the frame bag. They're also including foam bumpers for the mounting straps to minimize thread abrasion to the bag and attachment points Quality YKK brand water resistant zippers – with an improved, water resistant zipper 'garage' – control compartment access and help keep the weather out. Zippers are sewn with a stretch panel to relieve stress on the zipper as well. Stress even kills zippers. The large main compartment has a flexible divider inside, and there's a hydration port to make sure your whistle stays wet. There's also a compartment suitable for smaller items you'll access relatively often, like your map, phone, hard boiled eggs, uncontained pudding, marbles for playing marbles, your dugout, that ring you found that makes you disappear when you put it on, or whathaveyou. Frame bags such as this are light and reasonably voluminous. They are stable because they center weight low between your wheels and body, and they go places where racks and panniers are often troublesome, like singletrack. Note: due to the rough texture of the mounting straps, prolonged use may lead to scratched or worn paint. If you're worried about keeping everything looking pristine you probably ought to look for some other type of bag, or figure a way to protect the paint, such as duct tape, or tatting a top tube doily - for example.
