Friction Sun tour Bar end shifters have been fine with my 7 speed drive train rears ..
Friction/power ratchet

straight bars the thumb shifter is the way to go ..


New 10 speed' is all 10 on the cassette .. Old '10 speed' was 5 on the back 2 on the front
'21 speed' is 7 in the back 3 in the front.. ( 7 in the space of standard 6 )

a new '10 speed' with a triple crank would be a "30 speed " [10 in the space, of 8]


V can be the French 'vitesses' same thing as "speeds"
