That I've lived long enough for bar ends to come back into fashion! What a time to be alive!!! At least they have improved how they look I guess?

The install video (see 2:40) shows the end covering a couple mm of the end of the bar, and the grip slid in a corresponding amount. https://www.wolftoothcomponents.com/pages/locked-in-bar-ends-user-manual Normally on the GDH the end of the grip is actually slightly past the end of the bar due to the plastic ring that stops it. But yeah I can see that the physical end of bar (with bar end) will be a bit wider than with just the Ergon end plug.

I got my first ride on these today. I'll get more in the coming week I'm sure. I paired them with a grip change to Wolf Tooth's lockon grips. For a little background, I have pretty significant neuropathy problems in both of my arms due to long running Cubital Tunnel syndrome. I've had surgery but the pain still exists when I ride and sometimes it still lingers after. My problems are somewhat the opposite of Joe's, his seem to stem from being highly athletic and having forearm pump, mine stem from sitting behind a computer since I was 8 years...
