Concrete pull-back calculation along H-space map

I am trying to calculate the pull-back of a cohomology class on the loopspace of the algebraic $K$-theory space $\Omega K(\mathbb{C})$ along the H-space map of $K(\mathbb{C}).$ Let $b_k\in \tilde{H}^{ … 2k}(\Omega K(\mathbb{C});\mathbb{R})$ be a reduced cohomology class on the loopspace of the complex K theory space (it is in fact derived from the Borel regulator classes, but this should not matter). …
