Dan Almberg, Örebro. Sweden.
Built me a MTB 29 "with 130mm damping, it worked very good at the first try.
A picture with 3 bikes made of R8 tubes have backframes that are not self-made, my last one is the whole frame built with Docol Tube R8 from ME Racing Service AB. Due to 4130 and other common bicycle materials usually the frames break in the heat effected zone. Docol does not hardeen in the heat effected zone, so I hope it will keep improve the frames. I've been broken 9 frames last 5 years so it will be fun to test if my builds works better than the bought ones.
Oh, I'll keep using it!
