12 speed cassettes?
- Thread starter dump
- Start date
Huh?
10 spd 11-36, x,+2,+2,+2,+2,+2,+3,+4,+4,+4
12 spd 10-51, x,+2,+2,+2,+2,+3,+3,+4,+5,+6,+6,+6
if only
then i could understand
that this portion of the casette is idenical
10 spd 11-36, x,+2,+2,+2,+2
12 spd 10-51, x,+2,+2,+2,+2
ohh why ohhh wyy did i spend freshmen and sophmore math classes staring at Ms. C's assets (she was also the volleyball coach
) I could have comprehended that these are the same......aside from being pedantic
assuming a 30t front ring
2.72, 2.307, 2.00, 1.76, 1.57
3 .00, 2.500, 2.14, 1.875, 1.666
10s gaps
.419, .307,.235,.185
12s gaps
.5,.357,.267,.208
sure. the 10s is closer,
but as far as your derailuer is concerned, a 2t step is a 2t step....

Ok. So now you've agreed they're different can we leave that pointless part of the argument behind?
Go back and re-read what I actually said about WHY wide ratio cassettes and the mechs used with them function less precicely, smoothly and slower than narrower range components. This is true even during gear changes of just a 2t sprocket difference.
If you want to believe newer 12 speed systems shift better and your definition of "better" = faster or smoother or you'd be wrong. You'd also be wrong if you were to think 12 speed is either lighter, longer wearing or more durable. and as far as VFM 12 speed is absolutely abysmal.
BTW I've no idea what a freshman or a sophmore even is. I rarely even went to school after the age of 14.
The point is my derailleur was actually designed for a maximum capacity of 25t and can only reach a maximum sprocket size of 36t. And because of this across my entire cassette my mech's guide pulley is in a far more optimal position to actually derail the chain from each sprocket to the next efficiently. Which also keeps it in a position which gives greater chainwrap around each sprocket meaning chains will continue to be useable without slipping under load when the chain is worn way past the point where you could even dream of still successfully using a 12spd chain on a stupid little 10t sprocket even just to ride to the shops nevermind in mud.
