Echo cnc the dearer version if you are after spending that mutch. i have the cheaper ones and they are realy strong and never let me down. id get them if i was you.
Why spend more money when the magura is cheaper and even if the echo brake has a better performance the magura is still good enough. personaly i wouldnt get an echo one because off what ive heard.
I had the szme problem, i got a new bb and it started to happen. so then i just put the old bolts in and it sorted it (the bolts was clean with no lock tite on)
I cant think of any where but on the 10th of october there is quite a big ride in leeds, if youre interested then read the topic it is under rides/locations, Il be there.:)http://www.trials-forum.co.uk/index.php?showtopic=142433
