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.

Like some of Surly's other chain tensioning devices, Snuggnut keeps your rear wheel from slipping forward in the dropout under the pedal load of your powerful gams. It's specifically designed for bikes that feature 12mm horizontal, vertical-slotted dropouts and is particularly suited for singlespeed application. Snuggnut is CNC-machined for durability and good looks, and shares many design features found on Tuggnut and Hurdy Gurdy. Note: The Snuggnut is compatible with horizontal thru-axle dropouts only. If using 10/12 Adapter Washers and QR wheels use a Tuggnut instead. Snuggnut is not for use with MDS Chips. Compatible models listed below: - Wednesday - ECR 29+ - ECR 27.5+ - Ogre - Krampus - Karate Monkey SS - Karate Monkey 27.5

Hurdy Gurdy is another nifty device that keeps a rear wheel from slipping forward in the dropout under pedal load. It's designed for the Cross-Check's semi-horizontal front-loading dropouts, and will also work on many other similar dropouts. Hurdy Gurdy is investment cast of stainless steel for durability and good looks, and shares many of Tuggnut's design features. Its two axle holes allow for a wide variety of fore/aft wheel positions, it will work with standard QRs, bolted axles, and nutted axles up to 10mm.

Whether for derailleur clamp clearance, tire clearance, or personal preference, sometimes it can be advantageous to run the wheel further back in the dropouts. Monkey Nuts install into Surly horizontal dropouts to make spacing the wheel back easy. There are 3 different sets depending on the type of dropout and axle configuration the dropout is intended for. Simply select the correct version of Monkey Nut, install it into the frame, and slam the wheel all the way forward. Bang, done.

MTB fork seals are a vital protective part of the overall front suspension system, with a crucial impact on riding comfort and trouble-free operation in the harshest environments. This completely redesigned fork seal — adding on to SKF’s well established fork seals range that has already been available on the market for more than 10 years — consists of newly developed rubber compounds and new geometries for both the scraper lip and the sealing lip. The co-molded combination of compounds, together with improved sealing lip properties, offers enhanced followability on the shaft. In addition, there is a new metal insert and an open wound spring on the dirt scraper lip, effectively preventing the ingress of contaminants. - Extended sealing capability - Improved contamination exclusion - Reliable protection of the interior fork mechanism - Minimum friction for enhanced control
