Exclusive: Jens Voigt's hour record Trek bike

When it comes to embarking on the hour record attempt, timing is of course of the essence but it's not just a factor imposed on the rider, in this case Jens Voigt, but also the support staff and the bike manufacturer.

"To accommodate that chain line in the back, we've also manufactured some custom rear cogs, with the help of Shimano, that are spaced out so that the chain line is optimised. We've made a few different selections of cog sizes for Jens to ensure that he has the right gearing available to him."
