Surly Rim Strip
$5.00 - $9.99
If you make huge rims you have to make huge rim strips too, and that's exactly how Surly's Rim Strip came to be. Made of PVC and available in 3 colors it protects your tube from the inside of the rim with stylish simplicity.
Surly Dirty Windows Patch
$5.99
It's a little cloth patch that you can patch stuff with, or sew on a hat, if you are so inclined. For bed or for the ride, it's the perfect accessory for the fashion conscious.
Surly Nylon Rim Strip
$7.99
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.
Surly Rim Strip (Rabbit Hole)
$7.99
This is the correct rim strip for the Surly Rabbit Hole rim. This stretch-fit rim strip is 38mm wide and made of tough PVC. Plus, because it's visible through the holes in the Rabbit Hole rim, it's available in Black, White, Blue and Red so that you can color coordinate!

Surly Monkey Nuts
$20.00 - $24.99

Simply select the correct version of Monkey Nut, install it into the frame, and slam the wheel all the way forward. Bang, done.

Surly Cassette Cog
$30.00
Pair this cog with your Shimano-compatible rear hub, spacers and a lockring (sold separately) and discover the joy and simplicity of a singlespeed without the cost of a new wheel.

Surly MDS Dropout Chips
$33.50 - $49.99
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.
Surly Singlespeed Spacer Kit
$40.00
Pair this kit with a cassette cog of your choosing (sold separately) and discover the joy and simplicity of a singlespeed without the cost of a new wheel. The Singlespeed Spacer Kit includes a variety of high quality aluminum spacers so you can dial your chainline and a stainless steel lockring to tighten everything down right.
Surly Dingle Cog
$44.99 - $50.00
If you love the feel and simplicity of a fixed gear, but crave a bit more versatility from your steed, the Surly Dingle Cog has just what you need. By pairing the Dingle with two front chainrings that have a 2-tooth difference such as a 42T and a 44T (sold separately), you gain a gearing option and your wheel position and chainstay length stay the same. Suddenly your fixed gear is a two-speed so you can tackle varied terrain with more ease.

Surly Dirt Wizard 29+ Tire

Surly 8-Pack Rack
$125.00
Most of you don’t need the cargo capacity to land a helicopter on your rack. Sometimes, all you want to do is grab a sixer from the beer store on the way home, or pick up a nice bouquet of flowers. For whatever the situation dictates, Surly offers the 8-Pack Rack. Made from the same tubular cromoly steel as their front and rear touring racks, the 8-Pack Rack is a solid pedestal upon which you may rest a handlebar bag, grocery bag, minaudiere, satchel…or whatever you use to carry your bowling ball around. The 8-Pack Rack attaches to most forks with mid-blade and crown eyelets. It uses stainless steel hardware and has the characteristic durability, versatility, and repairability all Surly products are known for. The 8-Pack Rack has lots of barrel braze-ons, so you can customize your cargo tie-downs…or just bolt on as many lights as you can possibly find. It’s rated to carry up to 30lbs (13.6 kg) and comes in black or silver.
