In the end trifox didnt warranty the frame because they said that i jumped (used this bike only for gravel riding) and then they never responded again, i wanted tò call the service manager but obviusly never called, then i used a second Number tò see if they Just gosted me or they werent online, they responded in 3 seconds but obviusly when i said Who i was never responded again lol, dont buy a trifox frame because its good until It works then they basically scam you with warranty, the frame had Just One year, for me the problem Is sprinting but they never said tò not sprint, they also never said tò no Jump when i bought the frame tbh, so dont get scammed by trifox
