I bought a box of Handlebar End Plugs from Ebay. I have way more than I’ll ever use, so I’ll sell the rest for $6/pair. These plugs cover the whole end of the handlebar and grip.
They do two things:
- Protect the end of the bar and grip - grips can get ratty from leaning the bike up against things, or from crashes. Bar ends can also get bent from crashes.
- For me, most important - Safety - these caps cover the whole end of the bar, keeping it from taking a core sample out of your body in the case of a crash.
They’re meant for lock on grips, but you can use them for regular grips as well.
