For now I thank you. However, in November the frame arrived with a dropout with M1.5 thread and axle with M1 thread and I never received the correct components even though they were promised to me. Now I'm anxiously awaiting the spare parts but I'm still very saddened. On Thursday and Sunday I will not be able to participate in amateur competitions for which I have paid to register. I found myself with my ass on the ground and to get home I had to walk and push the bike lifting it for 17km.... If I think that I could have replaced the balance wheel with the new aluminum model and not have had any problems I get even more angry! For clarity, I must say that the frame has never had any accidents or falls. The pin broke while pedaling uphill. It is also true that the frame has traveled on many downhill mountain paths.
