For the contrasty light that the bike is photographed under I would concur that a reduction in development time would give more printable highlights. If fact, cutting the contrast even more, by dilution or time and aiming for grade 3 or even a bit higher would give more local contrast and and a more pronounced impression of sharpness...perhaps you would want to try 1/4 to 1/2 stop more exposure if you do this.

If you like Rodinal and really wnat to maximize the sense of sharpness, and with a reduction of grain try Pyrocat HD used as a semi-stand developer.

I cannot reccomnend any developer time for Trix Professional with {yrocat HD.
