Is your mountain bike suspension electronic?

I don't understand how this works without limit screws.

Right?

That's the dumbest thing I've ever heard a bike reviewer say. It's basic details about how it mounts, and basic details of Transmission.

Do better Singletracks.

I’ve long thought that electric shifting was a solution to a problem that didn’t exist.
One of my bikes is currently XO, one XT. They both shift great and easy. I have a slight preference for the Shimano as it will shift into a higher gear (smaller rear) 2 at a time when cresting a hill. Both will go 3 at a time into “easier” gears.

The slow shifting is an issue for undulating terrain. Since most North Americans don’t live within 30 minutes of “winch and plummet” terrain I think this is more of a problem than Brian realizes. Most reviewers live right near “resort-level” terrain, and more power to them. But it does make their reviews very out of touch with 90% of most people’s riding experience. The fact that he didn’t realize the limit to 2 gears dropped at a time is evidence of this. I hope to hear a second review from Jeff who is located around more undulating terrain which I think will be an important perspective.
