Stiffest bike iv ever tried, although i modified the frame a bit, so its 1730g and not 2010 or something like that. Rides like a dream, pretty responsivel.
Just some crappy pictures about my czar dual disc, i love this bike, feels so great with these brakes.
Spec:
Czar dd short frame
Tryall rims
Tryall stem
Monty bar
Dual hope mono trials 07'
Echo forged cranks
Wellgo Mg-1s
Echo rear hub
Author front hub
One of my friends ha a similar problem. He had to take apart the lever and clean it, there was some kind of pluggage. He managed to fix it and it still works pretty well. You can ask hope about your problem, they will help.
I have an FSA Orbit for more than 3 years now, it works very well, never had any problem with it, there is only one negative point about it, a bit heavy.
I think Danni Comas used to have aluminium rotor on his mod disc, it was on the rear, i think it was a plazmatic rotor. They sad it works much better in the wet...
