thanks guys!  
 
i've thought that someone used this bb and can say how it feels on the bike standing on rear wheel, keepeing balance, etc 
 
Alex Dark, increasing Q-factor is good for me - i usually hit the bone on the left leg above my shoe.. So with tms bb pedals will stand much more further from magura cylinder. 
 
Filo, you are right! i didn't thought about this fact. But for me it's not so important - i use hope pro2 trials, so i'll be able to make the chain line go almost straight )
