The fastest oversized pulley wheel system in the world is also available for SRAM Rival & Force 1 Type 3 derailleurs.
Featuring 14-tooth (upper) and 18-tooth (lower) pulleys with a narrow-wide profile, the OSPW X System for SRAM Rival & Force 1 Type 3 is available fitted with CeramicSpeed standard or coated bearings, with up to a 6-year warranty. The unique narrow-wide tooth profile of the pulleys ensures durable chain retention.
The system is fitted with a custom-designed, strong carbon fiber pulley cage assembly for outstanding durability and light weight. The cage design allows you to choose between two spring tension settings to customize performance and reduce chain drag. We recommend initial setup in the lower spring tension. This has been designed to leave the clutch mechanism fully functional for chain retention.
In the event that the low spring tension does not provide adequate shift quality on very rough roads, you can increase it to the high-spring tension, which corresponds to the factory settings.
Thanks to the high-quality CeramicSpeed Bearings inside, your product will benefit from a 3-5 times longer lifespan than stock, and it has been tested to deliver 30-40% less friction than conventional systems.
This product is completely developed and handbuilt in Denmark, including the top quality CeramicSpeed Bearings inside.
The OSPW X System for SRAM Rival & Force 1 Type 3 is compatible with SRAM Rival or Force 1X 11-speed with Type 3 clutch, regardless of the cage length. Note that the cage lock must be in the 8 o'clock position, not the 5 o'clock position. This product is NOT compatible with Type 2.1 clutch derailleurs.
In The Box:
- A complete 14-tooth/18-tooth OSPW X System for SRAM 1x
- CeramicSpeed bearing oil in 15ml dropper bottle
- Sticker Sheet

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.
