I think that the few people using the Evo are using the old type of rear brace, which doesn't break. At that price I think that they will carry on doing that.
unless they have a really bad case of orange fever.
Alternatively, I do have some slight seconds of my brackets that people could have at £10, a saving of £40 on the orange masterpiece if they drill their own holes in the brace.
("Slight seconds" were the result of my milling machine throwing a hissy fit and losing its way. Some of the chamfers and rads are not quite right but the parts will function as intended.)
