Lx M567 STI's

I don't know why you think that is a V-lever. It just isn't and there's nothing about it to suggest that it is.We_are_Stevo":1wjhl2j3 said:
If you look on the picture of the 97 groupset, you will see that the first LX V-levers had a high to low adjustment, which your earlier canti levers obviously don't have. The point being that using a canti lever on a V-brake will give very fierce stopping that is hard to control, and even with V-levers the early users of V-brakes were given a low setting option so as to replicate something like the soft braking they were used to with cantis.
As has been said, there was no LX STI for Vs until the Mega9 M570 in 1999.

I have in front of me a;
Dia-Compe Ss8 canti' lever = 25mm
Tektro canti' lever = 30mm
Shimano canti' levers - 25/27mm
Shimano XT V's = adjustable 27-35mm
Avid SD-1.9L V's = adjustable 24-33mm
Shimano 'cheapy' V's = 43mm
Specialized both Normal/V-Type = adjustable 30-42mm
The Shimano 'Servo-Wave Action' V's are adjustable 12-20mm!
There seems to be a certain degree of overlap, especially with the Xt's and the Avids - I was always under the impression it was the position of the cable anchor that determined the type?
A V-brake lever pulls a lot less cable doesn't it, due to the floating anchor being further inside the body of the clamp?
A V lever pulls more cable but with less mechanical advantage (that being made up at the business end of the brake)
The nadjustable XT V's have shims that you remove - doing so means when the cable is pulled and there are no shims the floating anchor point slide owards the pivot point and ramps up the mechanical advantage for even more powerful braking.
No Lever is the same as another but as you can see V levers pull will pull more cable

not sure which one this is

Well I obviously can't argue with something as starkly obvious as that; :shock:
However, given that there is comparable overlap between the physical dimensions of the canti' levers and the high-end V's which are adjustable for modulation (the Avids on the fly...) then that explains WHY the '94 LX work perfectly okay with V's (I've always used the two together!) and proving that V's actually ARE retro!
Yes, but there is no doubt that V-levers are better for V-brakes. As Taffy says, V-levers pull more cable for a given movement of the pads, so they have much better feel and modulation. BITD, it was felt that using canti levers with V-brakes was actually dangerous, as there was so little feel. If you are well used to it, that may be over-stating the case, but we must remember that these parts are made for everyone to use, from learners upwards. I think it certainly wouldn't be sensible for a learner to be let loose on a canti lever/V-brake combination.

Having just measured them all I can attest the various Canti's pull 15-21mm of cable, the XT V's pull 25-28mm, the Avid Speed Dial V's pull 20-26mm and the '94 LXs pull 21mm...
It would seem that the design of the lever is just as important as the geometry? The '94 LXs were obviously ahead of their time...
None of which alters the fact that I was hopelessly wrong in my original assertion though...

Didn't the length of cantis grow at around this point from the shorter older DX length to the longer length, wouldn't this have required more cable pull? This maybe the reason why the LX levers can be used with V's and I have also read that the M095 XT's that I have can be used with V's as well (they may also pull 21mm).

Probably explains too why I always thought V's came out earlier than they did?
I had 7-speed canti' LX STIs on my cro-mega BITD and when I first saw the V's I thought I'd have some as they were so much easier to set up. I just bolted them on and never thought anything of because they were brilliant...
To this day I've always assumed what I was blathering on about above was correct!
