Received and installed my RLETs a couple of days ago. I bought three because my shop looks like the site of a bomb blast in a hardware store. A dash of Armor-All on the inside, left the outside clean and dry for grip during install, which was very easy after giving up on other tricks involving compressed air.
Then I went for a ride. Wow.
The dampening mass of the rubber out on the end of the levers eliminates all high frequency vibration I may have imagined before RLET install, and now that temps are dipping into the 40's, the levers aren't able to extract heat from my fingers nearly as quickly as before, with the aluminum ball heat exchangers no longer exposed to an icy breeze.
I will ride more often, and with more confidence, pride, and stamina with what's got to be the best upgrade for the money. Thanks to all who've come before and committed their sweat, spit and time to researching, installing, and documenting RLETs for the rest of us.
