Wangta- you understand the difference between fully and semi-hydraulic, right?
Semi hydralic mean that there's still a bicycle cable in there... your levers pull a cable, which attaches to a master cylinder full of hydraulic fluid located SOMEWHERE ( usually down on the front fork ). From that point - the master cylinder, to the actual calipers is where it's hydraulic.
a fully hydraulic setup is like you see on stellas / new PX's, where the master cylinder is up on the headset, and when you pull the lever you're actuating the master cylinder itself. There's no bicycle cable at all in the equation.
Now, you've got to route a braided steel hose to carry the hydraulic fluid from the headset down to the brake caliper, which is a bit harder than routing a typical cable ). I think some folks do semi hydraulic because it allows you to maintain a stock looking vintage headset ( but on a p-series, who cares ) yet still gain the power of a hydraulic front disc brake.
Eric - thanks for the explanation. I actually wasn't aware of the exact difference between the two, but from posts above, assumed the full-hydraulic was a better choice, assuming they cost the same.
I'll have to look at the two and in detail, but it sounds like a semi-hydraulic would be fine for my purposes. I think I'd prefer to have a normal headset, but then again, I'm not sure how big the master cylinder is.
