I've had 3 denguras. The first one leaked on the first ride, was unusable afterward. The second one worked well, then I broke a hose, and rebled it with water. Huge mistake. It leaked all the time, I'd have to rebleed the brake every second day. It also became very spongy and slow acting with the water inside...not designed to be used with water as far as I can see. On the third one, I didn't want to run it, so I gave it to my brother and bought a maggie No problems with the maggie, quicker rebound, no spongyness, and the cylinders seem to move more, so it has better lever feel as well. I'd never buy another dengura. Too much hastle. They need to start using olives with them as well, makes shortening the hose a fack load easier.
