Alex Fayolle’s Polygon Collosus DH9: custom shock with ‘lockout’ for Fort William

We take a closer look at the bike that took the win at Lourdes

All eyes will be on Polygon rider Alex Fayolle this weekend at Fort William after the French rider unexpectedly took the win at Lourdes last month.


While poor weather obviously played a role in scuppering the hopes of many at Lourdes, it was still very interesting to see a bike — an alloy bike no less — with a far more diverse range of components than is usually seen on the top steps of the podium.

Walking through the Fort William pits after timed practice on Friday we spotted Fayolle and decided to take a closer look at his truly unique bike.

From the (ludicrously expensive) Trickstuff Direttissima brakes, Suntour RUX fork and Kenda Hellcat tyres to the fully custom shock, this bike is a real hodge-podge of parts that are clearly working for Alex and his team.

Fayolle’s DH9 is outfitted with a gold anodized shock that is handmade by his mechanic Hugues.

While producing your own shock obviously opens up an enormous number of tuning options for the team, most interesting is the inclusion of an on-the-fly low speed compression adjustment that acts as a semi-lockout.

Operated by an old Saint shifter — which itself has seen a little bit of customisation with grip tape on the thumb paddle to improve feel in wet conditions — the effect the adjustment has on the feel of the shock is really quite remarkable, during a cursory car-park squidge.

Each of the shocks is marked with a letter to identify them, though Hugues wouldn’t tell us what the T stood for!

Hugues claims that Fayolle likes to use this ‘lockout’ on faster, less rough and pedally sections of the course and fully expects him to use it on the infamous Motorway section towards the bottom of the brutal course this Sunday.

Although I didn’t catch his name, Polygon may have the best pit-pupper on the whole World Cup circuit, with Hugues delighting in showing off his ability to climb ladders
