I'm having a hard time understanding what your issue is. Here is your first post:
At winter found some cracks around link in front triangle. Carbonda claimed this as a warranty an said they send me new triangle in march. In march they said it delays to april. Now finally new triangle is ready, and they put me new recuirement - to cut off old triangle. At this moment I,m resting with shoulder injury. And I dont understand how I can dissasemble full suspension bike with inner cables with only one working hand. And I dont want to stay without rideable bike for recovery period, with easy rides. ( maybe shipping stucks for months). Carbonda do not accept my arguments. Earlier I was thinking about building trail bike on fm1002, may be now it's not a good idea...
You want to get a warranty replacement for your frame because it has cracks that made you feel uneasy enough about it that you contacted Carbonda. Carbonda responded that yes, appears to be an issue and should be replaced.
Then your complaint is that you are resting your shoulder and only have one good hand and can't disassemble the bike. Yet you will have to either way in order to swap the frame's front triangle.
Now they decide me to pay 500$ deposit, claiming to return it when new triangle arrives, and I cut off old cracked triangle. Wtf??? )
Carbonda offers a very standard compromise - give a deposit and they will send a replacement. When you get it swapped over, you will get your deposit back.
I don't expect anything from them. I just want ride my bike soon, if I cut off it now, it will be unrideable for unknown time.
Can you ride your bike right now, as is? I thought you were injured and the bike cracked enough that it is deemed a warranty replacement item, likely unsafe?
So you want to continue riding a cracked carbon framed bike, while injured, and then when the new front triangle arrives, disassemble and swap the parts over?
If so, pay the deposit. Not an uncommon practice or unreasonable thing for a company to request.
But why do you want to ride a broken bike that you were concerned enough that you asked the company for a replacement?
