How to get the veelo chapter style of the memoir class to pick up trimmed paper sizes?

I have defined how I want to cut my paper and I was planning on using the veelo chapter style. However it doesn't pick up the trimmed paper size correctly. See this example:

\documentclass[showtrims]{memoir}

\usepackage{graphicx}

\stockaiv

\settrimmedsize{242mm}{165mm}{*}
\settrims{20mm}{20mm}
\settypeblocksize{*}{33pc}{1.618}
\setlrmargins{*}{*}{1.5}
\setulmarginsandblock{3pc}{3pc}{*}
\setcolsepandrule{1pc}{0pt}

\chapterstyle{veelo}
\checkandfixthelayout

\trimFrame

\begin{document}
\chapter{My first chapter}
Notice how the veelo setting has not picked up the right paper size.
\end{document}


I have tried calling \checkandfixthelayout before \chapterstyle{veelo} also but that did not make any difference. What am I doing wrong?
