All,
I've been updated on this -- though this was our original intent, it proved cost prohibitive to do this. The hexes and VersaKeys will NOT be consistently aligned.

IF this is the case, what is your recomended method for mounting a 4x2 traction wheel live axle. A single hub?

John, Now that the hexes and Versakeys will not be consistently aligned, how would you recommend doing the following:



(Picture is of a gear being used on one side of a wheel, versakey on the other, just in case the photo gets removed/updated to reflect changes)

Would you replace one of the hex hubs with a bearing hubs and then rely on the gear's hex and VersaKeys to transmit Torque?

Do you plan on releasing different sizes and widths for the VersaWheels?

When will the CAD model of the Single Speed, single reduction transmissions be available?

A single hub is more than enough to transfer the torque. So I would recommend a single hub, and a hex bearing for piloting on the other side.

Not for this season. We made the VersaWheel in a very universal size which we thought teams would use -- for other sizes we have the traction wheels:

Yes, that's exactly what I'd do. The single gear is more than enough to transmit the torque. You may just need a pilot on the other side, depending on the width of the wheel.

Turns out a 1/2" hex bearing on the other side to pilot is more cost effective than another hub anyways.

The hub designs are such that only one side needs a Versahub to transfer the torque. We initially intended that the hex would be timed to a certain VersaHub feature, but we quickly realized that we could not meet our pricing targets with such a requirement so we relaxed the requirement.

Our reasoning for relaxing the requirement was that since the full torque load could be taken by one hub, then a hex bearing can be used on the other side if you are worried about deflection. As it turns out, the bearing solution is less expensive for the customer anyway.

Thanks. I wasn't worried about torque, but supporting the shaft on the other side. For some reason I thought the wheel bores were 1.25, not 1.125. What you and John suggest is a really clean solution, I like it.

It's also a great use for the handful of seized hex bearings we have collected through the years.

A few people asked about whether we would sell the shifter shafts independently. The answer is "yes" and they're already live on the site (linked from the kit contents section of the Ball Shifter page).

Short Output Shaft (w/ gears) -- as used in the 3-stage gearbox.

Without gears... just the shaft:

Does this apply to the 1/2" keyed hubs as well? I am assuming so but wanted to confirm anyway.

Yes, this applies to those.
