I had a long chat with the rep on a demo day up in the lakes. Asked about ISCG on the newer (at the time) heckler and he said it was 50/50 if people wanted it. As 2x & 1x is now becoming more accepted it’s probably time to do it.
As for both through rear the answer was they don’t need it. It’s true the back of my heckler is as stiff ans anything, the nomads & blur lt’s I tried were too. If the frame is stiff you don’t need the maxle.
As a company that doesn’t run to the this year/next year buzz it’s great design a product sell for 2/3 years then spend the time revising each model in turn. Frames don’t become bad overnight.
In a world where the mythical orange 5 is the best bike in the world the heckler can’t be old hat (tried both much prefer the heckler)
