Hm, is it 38 or 42!? kinda big difference. I've bought it but haven't received it yet. Sounds no good what johnsdevil tells about the sloppiness in the arms after just 500km!? I ordered it with straight ramps, so will try it with those first. I have a m7000 mcx 190, so I think I could get away with 42 degrees and up. I'll see how it holds up, may be an expensive way to find out a good angle to use... Heard good things about both dalton helixes and Hercules, may go to some of those when I know which angle to use.
Bikeman helix with the torsional, does it work good? Like to be able to adjust a little after conditions.
