Pro Bike Check: Isabeau Courdurier’s Custom SUNN KERN LT Team

2015 was Isabeau Courdurier’s break through season in the EWS which seen her taking to the podium steps twice alongside consistent placings in the top five, finishing off the season fourth in the overall. Shortly after the end of the season she announced that she would no longer be riding for the Rocky Mountain URGE Team, and in the following months came the news that she would be joining SUNN for the next 2 years. Most interestingly it was noted that she would be riding a fully custom extra-small SUNN KERN LT. Whilst in the South of France we took the opportunity to visit Isabeau and have a close up look of her shiny new race bike.

At first glance it looks for the most part, like the same frame layout as the larger models. It isn’t until you look a little closer that you see the significant detail changes.

The first major difference between the larger models is a shorter headtube. Internal cable routing also keeps things tidy.

On the larger models the top tube has a triangle connecting it to the seat tube. On Isabeau’s this has been removed and replaced with curved tubing to meet the shorter seat tube.

The shorter seat tube is also laid out in a vastly different arrangement to her team mate’s bikes.
