I am new to Bicycling. I have a question on gear shifters. Mostly the bikes are available with Revo Shifter and EF Fire Shifters. Which one of these are best and why it is?

Product recommendation questions are generally a poor fit for a Q&A site since the answers quickly become out of date. There are a number of previous posts that will help you know what to look for when buying a new/first road bike, commuter bike and mountain bike.– Gary.Ray ♦Commented Feb 20, 2015 at 19:53

There is no best. It is purely preference.
Most high-end bicycles are equipped with the rapid fire levers - but this may be purely down to market consensus ie. what sells a bike.
Some XC racers still use the gripshift shifters and SRAM still make the high-end shifters.
I used gripshift years ago on my first mountain bikes but found them quite fragile in a crash.
Gripshift - you can change a whole stack of gears in a single twist. Rapid fire requires multiple few clicks to achieve the same movement. But this has not been a problem for myself in practice - if you read the terrain ahead.
The rapid fire levers are more robust and I am yet to break one.

I prefer the Shimano 18-speed (2 up front, 9 in back, with rocker bar to get up to 1-1) out of prodxn but shim will build it custom for you. The Townie 2011 2100d had this derailleur combo. good stuff. buyer beware--rear derailleurs break EZ.– Tapper7Commented Jan 14, 2017 at 4:56

@Tapper7 What's a rocker bar? Google isn't helping me, except a bunch of Chinese patents in, well, some combination of patent-speak and broken English. Commented Feb 28, 2018 at 13:38

The rocker bar helps the rear derailleur bump up to a super-low gear. That's just what I call it. I'm sure Shimano has a more technical term. Since the trend is now to have 1 gear up front and multiple in back, the lowest one often has a significantly larger diameter (and diameter-differential) than all the others.– Tapper7Commented Mar 9, 2018 at 20:12
