heres the story i got a gu frame kit for christmas and put it together on the day with it i got some taped echo cranks and have had no problems untill today.i was riding and noticed the pedals were fairly loseso i borrowed a spanner and tightened them up and then when i went to ride again it felt like the cranks were bent. i obviously knew they weren't as they were new so i took the pedals of to see if it was them and they came off at a angle as if i had cross threaded them but i knew i hadn't i the cranks would have felt like they were bent ever since i put it together. so i started to think of ideas to solve this and i've come up with 2 ideas 1. drill the thread and tap a bigger one and use a pedal with a bigger thread like truvatis have 2. in the end of the pedal drill a hole and tap a thread in and bolt the pedals on any sugestions would be a great help or if you have aan easier way any thing at all apart from buy new cranks
