EDIT: Also, any COF data on the new wheels/tread?

EDIT 2: What is the ratio between the output shaft and the encoder shaft in all three configurations? Arg! So many questions

EDIT 3: (Until I'm directed elsewhere, I'm just going to dump my questions here) Are the broaches on the versahubs all aligned relative to the bolt circle identically? For a 2" wide wheel, it looks like 2 hubs per wheel would be a good idea.

Cannot wait for this season to start...even moreso than before!
Hi Jared,
1. You can mount in a few different ways. The simplest way is to attach the (included) mounting angle to the 3rd-stage face plate using two of its mounting screws. Alternately, one could face-mount this transmission using those same screws. I personally expect many teams will eliminate the output plate entirely, and just integrate that pattern into their drive train. We spent a lot of time talking about how to mount our gearboxes, and believe we've come up with a very versatile solution which should serve inexperienced teams, and also veterans. Our intent is to provide more in-application examples as we build towards kickoff.

2. We will post full CoF data for all wheels and tread in the coming weeks. Our team is redoing all our testing with the final production wheels (using the tilt-test) to ensure we provide the right data to our customers. Everything is in the ranges you'd expect, we know traction is important...

3. On the ball shifter: the encoders turn at 3x the speed of the output shaft using our stock (included) mounting method. On the single-speed, double-reduction the encoders spin at the same speed as the output shaft.

4. Unfortunately no, the VersaKey pattern is not consistently aligned with the hex broaches. Though this was our original intent, it proved cost-prohibitive to achieve.

-John
