The Porteur House also comes with a shoulder strap so you can take the bag off the bike and use it when you're at the Hallmark store shopping for your little figurines and keepsakes.

Surly Front Rack
$145.00
Surly Racks are well-thought-out, durable, expedition-worthy racks that work with most panniers. While their racks aren't limited solely to heavy duty touring, that is what they were designed for. When you're out on the road, the best option is to never ever have anything ever go wrong ever. Right? That's never a guarantee though; so having something that you can repair if it does break can be pretty clutch. Thus, the main bodies of Surly's front and rear racks are made from tubular CroMoly steel with stainless hardware. This means you can probably find someone out there that can torch it back into one piece in the rare instance things go south. The Front Rack is height adjustable and provides either a low or high pannier mounting position, which can be handy depending on terrain. When the ground gets rough, keep your gear high and dry. When the path is smooth and easy, you can load things low and keep everything balanced and stable, with the platform above the wheel providing yet more space for more stuff. It's worth mentioning they've redesigned the Front Rack hardware to be simpler to attach and more compatible with things like disc calipers and fenders. Surly also made attachment plates specifically for their Uni-Crown forks for yet more fork compatibility. This simpler design has fewer moving parts and costs less to manufacture; ergo, costs less for you to purchase. Surly's front rack WILL work with disc brakes on the Troll, Ogre, and Disc Trucker frames. It may take a bit of work to get clearance around the front caliper since the many different calipers out there are many different shapes. The new attachment plates will limit any DIY ingenuity you might need, but if you need to throw a washer or three behind the lower left bolt where the plate attaches to the fork dropout, that's not a big deal. As part of Surly's ongoing effort to make this planet last a little longer, they recently started shipping their racks with a small, reusable Surly Tool Bag that houses the rack struts and hardware. This switch helps eliminate the use of some polybags, thereby minimizing excess waste. Plus, you get a free tool bag out of the deal. Surly Front Rack will haul up to 32kg (70 lb) of well-secured, well-balanced gear over roadways and maintained off-road trails. Front Rack specifications: - Tubing diameter: 10mm - Platform dimensions: 230 x 170mm - Weight: 1382g

Surly Mountain Frame Bag
$180.00
Surly mountain frame bags are designed specifically to fit in the main triangle of your Surly frame. 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, you know it won't interfere with the mounting straps on the frame bag. Handmade by Revelate Designs in the U.S., these things are made of Dimension Polyant VX 42, a synthetic sailcloth. This stuff is durable, rip resistant, and tightly woven and laminated to make it highly water resistant (but not fully waterproof… Revelate advises using drybags inside if you risk riding in extended downpours or underwater). Compartment access is controlled by quality YKK brand water resistant zippers. The large main compartment has a flexible divider inside, and there's a hidden pocket too. 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 becoming more and more popular. They're light, reasonably voluminous, stable because they center weight low between your wheels and body, and they go places where racks and panniers are often troublesome, like singletrack. Surly offers them in ten sizes for many of their off-road frames. Buy the bag that matches the size of your frame based on the handy sizing chart. Note: due to the rough texture of the mounting straps, prolonged use may lead to scratched or worn paint. Those worried about keeping their frame looking pristine should immediately look for some other type of bag, or figure a way to protect their paint, such as duct tape. Or tatting a top tube doily. For example.
Surly Midnight Special 650b Fork
$185.00
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 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.
Surly O.D. Crank (PressFit BB)
$250.00
Surly designed the O.D. crankset to offer frame and tire clearance while maintaining a reasonable q-factor (pedal stance). Maximizing the distance between the chain and the tire is important on fat bikes such as the Pugsley and Moonlander, or if you're running really big tires and rims on some other bike (like our new Krampus, for example). With normal cranks, wide tires on wide rims can rub the chain when in the lowest, or farthest-inboard, gear combinations. Like the MWOD crank, the O.D. crank doesn't just add a longer spindle to move the rings outboard. Rather, it does away with the big ring of a standard triple and moves the middle and granny rings to the outer and middle positions. This effectively moves the rings outboard without moving the arms outboard too. The O.D. is a simple, dedicated version of this idea. Neato! Forged of 7000 series T6 aluminum, the O.D. crank is a 2-piece, with spindle embedded inextricably in the drive side arm. It's a dedicated 2x, although its chainline is outboard a bit compared to standard mountain cranks, and it is 9 and 10 speed compatible. The 132mm, PF41 bottom bracket O.D. crank is what goes on the Ice Cream Truck bikes, so if you've got that setup, that's your crank. Surly also offers 33t and 20t rings separately. These chain rings are designed to shift best in specific combinations….change to a 39/22t, for example, and your shifting will suffer. The bearings on which they spin are also worth mentioning: Surly upgraded the bearings on these and the Mr. Whirly and MWOD cranksets to aftermarket Enduro bearings with double labyrinth seals, meaning they actively shed and stay clean of dust, muck, and grime, even in wet and muddy climates.
Surly Dummy Bags
$275.00
Surly Dummy Bags are designed to work with the Big Dummy cargo bike and other cargo bikes using the Xtracycle Longtail Standard. They were designed to provide the functionality and reliability you expect from Surly products. All materials, from fabric to thread to hardware, were chosen specifically for their given applications — as light or as heavy as they need to be to survive the battle against the elements and daily wear and tear. The 840d nylon exterior provides abrasion-resistance, while the tarp liner keeps cargo dry. Dummy Bags feature a roll-up rain flap, an expandable cargo flap, and a water-resistant inner pocket with an optional divider. Surly also included little details like stainless steel drainage and cinch cord grommets, replaceable cinch cords, and replaceable wear patches at the disc caliper and derailleur contact points. Dummy Bags work best with Surly Dummy Rails and Dummy Deck. Each piece will work with older parts — your Dummy Bags will play well with Xtracycle rails, for example — but fit and use of all features will not be ideal.
Surly Trailer Hitch/Yolk Assembly (trailer sold separately)
$300.00
Surly's Trailer Hitch/Yolk Assembly is the correct hitch for Surly's Bill and Ted Trailers (sold separately). This fine chromoly hitch securely and quickly attaches to your bike using the included proprietary quick-release skewer.

The hitch fits most bicycles whether they feature full suspension, disc brakes, rear racks and fenders, or you name it. And it works with bicycles with wheels as small as 20 inches and as large as 29 inches, while always keeping the trailer bed level with the ground.

Surly Cross Check Frameset
$500.00
Cross-Check is a tough-as-nails, super-versatile road bike that performs astonishingly well on any surface. There is no such thing as one bike that can do it all, but Cross-Check comes pretty damn close. It's a dyed-in-the-wool commuter and utility rig. It was a gravel crusher long before "gravel bikes" existed. Some people have even raced cyclocross on it. Though, we don't necessarily condone that behavior. Cross-Check was the first complete bike we ever offered. Since then, people have modified them hundreds of different ways to suit their riding styles and preferences. There’s a reason that nearly every person who has ever worked for Surly has owned one. - Semi-horizontal dropouts for singlespeed compatibility and wheelbase adjustability - Gnot-Rite dropout spacing allows installation of 130 or 135mm hubs - Accommodations for front and rear racks and fenders - Clearance for 700 x 42mm tires with or without fenders
