I have been taking a close look at V-brakes, since those that sit on my winterbike have become slow, craving frequent adjustment and service. Looking in last years catalogues I chose Deore XT with the model no. BR-M760. The reason for that choice was the technological advantage of the parallelogram pushing the brakepad to the rim in a 90 degree angle - plus the "Ultegra level" price of luxory within reason. (44 euro/pair)
But these brakes turned out to be out of the shelves of many of the shops I normally deal with. They offer a new 2008 version of the Deore XT V-brake - WITHOUT the parallelogram. If I want paralellogram in a 2008 version, I have to move up to the XTR model, which to me is luxory beyond reason. (100 euros/pair)
If I keep looking I suppose I will be able to find last years luxory of XT brakes with parallelograms. Byt why is Shimano stepping down instead of up in the 2008 version of Deore XT V-brakes.
It is an unwritten rule, that there must be a little progress in every years new model, and that the technology spreads down from the top to the secondary groupsets.
Is anything wron with the parallelogram technology? Why has Shimano stepped down to the old more simple technology?

In theory, as you note, it seemed cool if possibly excessive.
In practice they have not proved durable nor any better at stopping a bike. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971

With Shimano (and others) I think a better statement would be: It is an unwritten rule that a new gimmick will be tried every year. Some gimmicks will entice enough buyers to continue in production. Other gimmicks will not, and will be replaced by new gimmicks.
Shimano has a long history of such gimmicks.

There was no significant advantage. And my one friend who bought those was troubled by embarrassing brake squeal.

The main reason was probably that it didn't attract enough buyers.

Try looking at Magura rim brakes, parallel push, nice "feel", and very low maintenance. I've got HS11 on my tourer and I'm well pleased.
HS33 have more lever travel per pad travel, so offer stronger braking. Given that the HS11/66 have loads of lever travel available/spare, I'd seriously consider going to the 33s.

Are you sure? I was not aware of this. I thought they were both the same. But if you are right that would go some way to explaining the differance in price. Must say the HS11s have plenty of pad movement and good modulation. Never felt any different to the HS33s I've tried.

The HS33 have slightly less (25%?) pad movement, purely because their master cylinders are a bit smaller. I think they realised they were being a bit conservative with their original brakes (11/22/66), allowing more pad movement than is necessary, and could afford to change the mechanical advantage a bit.
You'll note I said "seriously consider" - doesn't mean you actually need to do it :-)
(Pity they never did the same for the 66s, and, worse, dropped the line completely. I wouldn't mind a bit more mechanical advantage.)

My XT front brakes, from 2003, didn't just squeal, but rather provided a veritable organ concert, with both high and low-pitched tones. I ride a lot near alpine meadows, and didn't want to scare the cows. Nothing helped except giving up and changing to cheap Deore brakes.
Thanks for warnings, theories and suggestions. I think a set of Magura HS 11 (or even 33) can be justified on my winter commuting bicycle, which is supposed to bring me trough 2500 slippery kilometres of Nordic darkness between November and April. I hope my Mrs will understand the need of investing 140 euros in safety equipment.
It's an amazing amount of insight that can be collected in this newsgroup within a few hours. I appreciate that.
