The field at the 2015 Challenge Heilbronn is loaded and here are some impressions of the bikes, athletes and happenings during the bike check-in. Especially interesting is Kienle's bike that appears to have SRAM's new electronic group. Surely Jan Frodeno is not the only German who gets to ride that long awaited group.

Sebastian Kienle's new custom painted Scott Plasma sits next to Maurice Clavel's Plasma and Andi Böcherer's Kuota. The cover on the aero extensions on Kienle's Plasma and the look of the derailleurs hints that this is not a standard SRAM group.

The 2014 Ironman World Champion seemed relaxed and ready. He will have many eyes on him tomorrow.

The transition area for this race is indeed in a parking garage, as indicated by the two previous pictures.

Andreas Dreitz with Erdinger mate Michael Raelert will surely be in the mix.
