why do sram give their mechs speeds - 9spd or 10spd if they are all 1:1 ratios? is it not the shifter that decides the speed of the mech as the amount of cable used will be different depending on shifter?
opinions are worth exactly what you pay for them ;-)

10spd is 10 gears
and the pull ratios are not the same."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

i though the pull ratio was the 1:1 is that not the point of it? can you give a bit more detail as its bugging me!!opinions are worth exactly what you pay for them ;-)

The pull ratio is almost 1:1, but not quite, and 9 and 10-spd are different. The shifter is only half the equation, it's the mech that determines how much one click of the shifter is in relation to movement across the cassette. But, what you say is true of older mechs: apart from differences between SRAM and Shimano, the speed was almost always determined by the shifter.0
