We have been following with interest the progress of Louis Grillon (aka the Grillontosaur) this season. This young (9 years old!) trials rider who has dominated the podiums throughout the 2008 season, in all four corners of the world, perhaps most notably in the Poussin World Championship or when he won the Koxxdays green category. This year he has already won the title of Central France/Paris Champion in the N3 category.
At the end of last year we presented his bike, the Koxx Foxx 2009, a bike specially adapted for younger and smaller riders, the design, specification and finish of which have nothing to envy in the ’real’ bikes of older riders: 6061-T X-Diamond Alu frame and fork, 108.9 Freewheel, KMC Light chain and Try-All Holes rims.
The Grillontosaur and his dad Laurent have been hunting down those extra grams (Ti bolts, a carbon BB, drilled forks and hubs, lightened axles etc.), and in March the bike tipped the scales at a paltry 6.84kg (A 6.84kg Koxx Foxx !). The bike has been further lightened and now weighs just 6.66kg! The weight of the beast - which ex-punk Dad Laurent is pleased about!

The recipe for a Foxx Light:
Laurent tells us the secret of this devilishly light Foxx:
Diet number one...
It wasn’t at all complicated to create such a light bike!
Here’s the recipe for your own "Foxx Light"...
drilled magnesium pedals,
a light 90mm x 25° stem stem (ours is a prototype, but there’ll be similar ones on the market),
machined out hub bodies
We replaced the fork with an XTP model (also in aluminium), and drilled it.
Diet number two...
The Foxx Light has gone on another diet and has dropped from 6.84kg to just 6.66kg! Here are the new modifications:
carbon bash plate,
machined out crank arms,
new TRY-ALL pedals with Ti axles and bolts.

Coming soon on Tribal Zine, an interview with this incredible young rider in which he tells us about himself and his bike!
