2.12 Drive wheel & Cross tube positions

The drive wheel mount has three attachment positions with 25 mm spacing to allow variation in the 

wheelbase length. The middle position is the standard configuration. See Figure 10.
The cross tube is mounted with screws through holes in the back of the wheel mount. To simplify 

assembly these screws can be accessed through the large hole in the brake disc. Be careful when doing 

this assembly that the brake disc is not damaged. See Figure 11.

NOTE:

 The cross bar must always be in place.

NOTE

: When the wheel mount is moved the fenders also need to move. See section 2.15.

NOTE

: Thread locker (Loctite 2400 or equivalent) must be used on the screws.

A - Wheel mount 25 mm forward
B - Wheel mount mid position
C - Wheel mount 25 mm back
