Esp
 

What is ESP? I am looking at some SRAM shifters but they are "ESP" compatible only. What is ESP?

Extra Sensory Perception???

ChrisL, I'm gonna pass you up dude...

I do not remember what ESP stands for but...... ESP shifters will only work with Sram ESP Derailleurs. It has to do with the amount of cable the shifters pull.

Fubar5: he already knew that. :p

My company has a product set named 'ESP+ Solutions Suite'. It stands for Electronic Statement Presentment - not appropriate here, methinks.

Until I find out what the letters really stand for (if anything), I will assume that it means "almost shifts just by thinking about it."

SRAM do two types of shifters, Shimano compatible and ESP.

The Shimano compatible range use 1-2 cable actuation. I don't know much about the bottom end but the top end Rocket shifts very sweetly.

The ESP range has 1-1 actuation which SRAM claim gives more precise shifting. The ESP range starts with ESP Gripshift 3 (which works very well IMO) and goes up to ESP 9SL.

As you go up the range the higher end shifters have an easy change cable port, but do suffer from an unneccessary 'pointer behind window' indicator, but then so do some of Shimano's shifters. Most of the shifters are available in both half-pipe too long for my taste (you could accidentally shift) or shorty (you'd have to have severe hand-coordination problems to accidentally shift). Some of the shifters are available in an 'amy' grip which is of a narrower diameter for small hands.

ESP rear shifters can only be used with an ESP rear mech. All front shifters including ESP are compatible with Shimano front mechs.

SRAM are about to launch a new Derailleur called XO I think.

Thanks guys. Are Rapid Fire Plus as prone to break as the Push/Push??
