Using the same CAD and 3D printing we used for the side-tube mount, we've also redesigned the mount for 22mm blokart^® steering tube.
It's made of nylon so it is very rigid and doesn't move at all once the screws are tightened down.
Another big improvement are captive nuts on the lower mount. Installation is a breeze with just a screwdriver.

The mount comes with two 8-32 nylon lock-nuts in the lower mount and your choice of 56mm-long 8-32 machine screws to mount a Viadna micro-cleat, or 2 1/2" screws (flat or pan head) you can trim for your favorite 27mm cleat.

The price is $40. US shipping is usually about $5.00.
A Viadana carbon-fiber ball-bearing cam-cleat and fairlead (as shown in the photo) are an additional $13.00.

Because of low demand, this is a special-order item, but I can usually make one in a few days. Send me an e-mail or call if you're interested in getting one.
