At first, this frame broke when 4 month from date of selling gone. it happened above bottom bracket
monty didn't make warranty change.
Ot Pi told me that it's my problem, if I want to change a frame I need to buy it. A little strange, isn't it?, because monty promised half year warranty.
(i'ts not streight his speach, but meaning was so.)
so, I repaired it, but after 1 month frame broke again in other place.
I repaired it again.
but now I think it can't be repaired.
monty sucks
