Surly

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.

The Knard is a tire that just makes sense. With its tightly-spaced, low-block tread pattern, it provides the perfect ratio of traction and low rolling resistance. It grips well on all sorts of different surfaces and will haul some sausage on hardpack terrain or groomed trails. If you want a tire that has a little less bite and a bit more speed but don’t want to sacrifice traction, look no further. With sizes ranging from a svelte 41mm all the way up to a hefty 4.8”, there’s a Knard to solve all your fast-rolling needs. - Folding bead - Casing: 60 TPI - Max pressure: 35psi - Weight: 1170g

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 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.

Single chainring drive train setups are all the rage these days. With the introduction of exceedingly wide range 10- and 11-speed cassettes, the need for two chainrings has become a thing of the past. But when you only have one chainring, the only thing standing between you and a long walk back to the trailhead is you making sure you don't destroy your one chainring. 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.

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.

The 12mm slotted MDS dropout is the newest chip for Surly's MDS equipped trail frames. You like chips, don't you? The 12mm slotted dropout chip uses a standard derailleur mount for maximum compatibility and is made of cast and machined 6061-T6 aluminum, with a fender eyelet. What's the coolest part about the 12mm slotted MDS chip, you ask? The fact that it also has the capability to run a 12 x 142mm thru-axle in a single speed configuration. This is good news because single speeds are good news. When you get an MDS equipped frame you're getting the option to set it up however you want. You can run a 142 x 12mm thru-axle rear end with a direct mount Shimano hanger, standard 135mm QR or The Mighty Singlespeed. The way this will work is that Surly complete bikes that feature the MDS will ship with whatever chip is compatible with derailleur spec. For instance, the complete Instigator 2.0 ships with the 142 x 12mm thru-axle Shimano chip. If you want to change it to a singlespeed later (and why wouldn't you?), all you have to do is get the SS chip. Frames will ship with all three MDS chips so pick your poison. The 142 x 12mm and 135mm QR chips are made of cast and machined 6061-T6 aluminum and The Mighty Singlespeed chip is 304 stainless steel, because the two words 'aluminum' and 'singlespeed' should never be too close to each other. Bad things can happen…. As you can see, the MDS gives you not just different build options, it lets you use a more varied selection of parts for your frame up builds. The MDS is featured on most of our trail bikes. That's right: Krampus Ops, Karate Monkey Ops, Instigator 2.0 and Ice Cream Truck frames all sport these puppies.

Midnight Special is a road plus bike designed to provide comfort and speed on those all-day rides that extend well beyond fresh pavement. Midnight Special shines on pot-holed, deteriorating pavement and the occasional long stretch of gravel. Its 650B road plus tires eat up road chatter and absorb all the bumps in the road like the champion it was designed to be. When it comes to road bikes, we just want to toss a few bananas into our pockets and see where the road takes us. We seek out varied surfaces on our rides and frequently go from pavement to gravel to worse pavement. Midnight Special allows us to accomplish all of that quite comfortably. - Higher volume tires allow better fine tuning of tire pressure on varying surfaces and create a wider contact patch for increased traction - Modern road standards like flat-mount disc brakes, 12mm front and rear thru-axles, and a 44mm head tube - Clearance for 650B x 60mm or 700c x 42mm tires without fenders (650B x 50mm or 700c x 38mm with fenders)

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
