Press fit is a great idea in my opinion , if it works fine for headsets and even 10 year old frames that have had multiple headset changes are still going , then bottom brackets should be fine.
In reply to jeff, exactly what mark said haha
Cheers dman
Built it and give it a pasting yesterday and seems all gravy. Loads stiffer than the tr it replaces which is always nice, and far better chain line
Soooo, front hub mk2 has been pretty well beaten and still very much in one piece so cue rear hub mk1!
Widest flange spacing I could reasonably get away with ( whilst being symmetrical )
M10 ti fun bolts
7075 for shell and axle and spacers
28/30 carbon fibre shell
Vudu glu to stick it all together
Side hops in my opinion are largely down to how
Much fast twitch muscle
You have , most of the best riders of the world go from a normal position to fully preloaded to extended in a very short amount of time.
6082 is the uk equivalent of 6061, far lower strength than 7075 that most trials frames are made from.
you'll buy at t6 temper presumably but after welding will be at t0 at the haz ( heat affected zone ).
Without heat treating the area around the welds will be significantly weaker due to the rapid cooling of the metal resulting in the crystalline bonds in the metal not aligning correctly.
Pretty sure I'm right in saying that.
