Installing the Rolling Jackass on a Surly Big Dummy or Xtracycle Edgerunner

Put a little grease on the first few threads of all hardware to prevent galling of the threads.

Remove the stock side stand if you have one. You may cushion the paint of your frame with tape or inner tube rubber, if you wish. Some left over cloth bar tape also works well.

Set the centerstand base on the frame tubes. Slip the two u-bolts over the lateral tube and through the holes in the base. Start the nuts and tighten them finger tight. Do the same with the two bolts that hold the curved strap clamp over the oval boom tube.

Tighten all six nuts to 4-5 Nm, making sure the centerstand base sits square to the frame. The U-bolts are 1/4” thread, taking a 7/16” wrench or socket. The strap clamp uses M6 hardware, taking a 10mm wrench and a 5mm Allen wrench.

Route the actuation cable housing along the frame, retaining with zip ties, and install the lever on the handlebars. The lever should be installed in a location that allows it to be pulled all the way to the bar, without interference. Enough cable and housing is included to fit most setups.

Actuate the stand by pulling on the lever, and pull the bike back and up onto the stand. Take note of the elevation of the tire which has been lifted off the ground. Too high and it will be difficult to set the bike onto the stand, especially when loaded. Too low, and the bike may be unstable when parking on uneven or soft ground. Aim for about 1/2” by adjusting the threaded feet. Lock the feet in place by tightening the jam nuts against the leg with a 9/16” wrench.

Double check that the cable tension is sufficient to actuate the stand. When the lever is pulled all the way to the handlebars, the feet of the stand should be touching the ground. If not, there is a barrel adjuster on the lever, and one at the base of the stand that will allow you to fine tune the cable tension.

The stand is now ready for use!
