Surly Modular Dropout System

Sometimes a Sub-11 with a hanger doesn’t cut it, and I’m not talking about a sub for your Escalade. Surly has introduced their new Modular Dropout System, adding a different level of versatility to select frames, and a compatibility with the latest tech that works and old school tech that never stopped. From left to right, the track fork end dropout chip, the QR derailleur hanger chip, and the thru-axle derailleur chip. Why the change? Rear entry track fork ends are simple and work great for single speed setups, add a derailleur hanger and it can get challenging to remove and reinsert a wheel, especially on the road or trail. Add to it that the latest Shimano Shadow Plus rear derailleurs require a specific placement in relation to the axle to work properly, different than that of the traditional Surly trackends with a hanger, and it just makes sense to move to a modular system. It also allows for thru-axle setups that are on their way to being the new standard on mountain bikes. This system just works better all around and only adds $40 to the cost of a frame, how very Surly. Framesets will ship with all three chips, complete bikes will come with the one that fits the stock configuration. Currently this is on the new Instigator, Karate Monkey, Ice Cream Truck and Krampus Ops frames, but I’m certainly not the only one wanting this on a Pacer or Crosscheck and it wouldn’t surprise me in the least to see it trickle down the line in future years.

    solid concept, but a bit of a loss that it doesn’t officially support belt drive.

    It looks like the spacing and bolts would support cutting the dropout for it.

    For fucks sake, belt drive, really? This is a solid concept, period. Belt drive maybe not so much.

    Jimmy, I agree. This is a great, well conceived concept.
