Tubus Rack Extenders for Surly Karate Monkey

Chris with Karate Monkey

The Surly Karate Monkey is a well known machine in the world of 29ers (bikes with extra large 29″ wheels). The horizontal dropouts are great for single speed, fixie or internal gear set ups, yet a derrailluer hanger on the dropout makes it easy to add gears.

Chris digs his Karate Monkey a lot and came in ready to add a sweet rack and get some nice panniers for hauling a bit of his world around with him on his bike. The Tubus Logo was his rear rack of choice, but it looked like it would barely clear his rear tire (too low!) and being that he has a pair of bigger tires at home (to say nothing of fitting fenders to the bike) this tight clearance cannot be ignored.

Lucky for him he is well versed in a software program called Solidworks. He created a drawing of the hardware he needed to extend the height of the Logo Rack and then sent his drawing (as a digital file) to a machinist that made the hardware (and even anodized them blue to match his bike).

The disc brake side (pictured above) is using a 17mm Disco Rack Spacer (a Perennial Cycle custom product) as a way to clear the disc brake.

Very Nice work Chris!

    Nice work! I have a touring bike and am finding it very difficult to get a rear rack on my bike. I am interested in how you did yours.

    I like what you’ve done here.
    I tried a similar approach a few years ago to enable a bit of offroad touring.
    I made the mistake of using a good quality, aluminium rack which completely failed after a day of bouncing around on flinty downland.
    I’ve used Tubus ever since. You can’t go wrong.
