We show that the technical condition of solvable conjugacy bound, introduced in [JOR1], can be removed without affecting the main results of that paper. The result is a Burghelea-type description of the summands and for any bounding class , discrete group with word-length and conjugacy class . We use this description to prove the conjecture -SrBC of [JOR1] for a class of groups that goes well beyond the cases considered in that paper. In particular, we show that the conjecture -SrBC (the Strong Bass Conjecture for the topological K-theory of ) is true for all semihyperbolic groups which satisfy SrBC, a statement consistent with the rationalized Bost conjecture for such groups.
