@lenmerderdenfer The tab is probably the better way to go in a sense that it will be more resistant to the torque that the gyro will apply to the system while braking and simultaneously turning. Also: It is very costly to broach or machine splines into anything. It isn't that Straitline didn't make it earlier, it's that the market was so small that it wasn't economically feasible. Now that they have their own technology that requires it, they contracted/tasked/worked with Cane Creek to design a solution to their problem.

The cost of bringing a prototype/item into production.

It was quite honestly the obvious solution. If you actually wanted to jump on the idea and invest your own money at making a viable solution before Cane Creek could, you should have. But also considering Straitline went with someone who has the available capacity to produce what they need, to the spec they need it, within the timeframe, they did what worked for them. Not to mention, you would have a very difficult time getting your hands on the specs for the Gyro itself.

Whatt? Stick to your curb hopping.

He thinks: I'm totally going to land this, BROWN POOOOOWWWW" Then he bails. Hard.

Then change up your tire selection, and crank the fuck out of your axles.
