Pro Bike Check: Theo Galy’s SUNN Kern LT 29 Prototype

The SUNN Kern LT is the flagship in SUNN’s enduro line-up and has represented the French cult brand at the Enduro World Series for several years. At the penultimate 2018 EWS appointment in Ainsa team rider Theo Galy rolled up on a brand new prototype — the latest incarnation of SUNN’s Kern LT. The new version features twenty-nine inch wheels, an all-new carbon frame to replace the previous aluminium version and a very futuristic look — the most striking upgrades on the new Kern. In Finale Ligure we had the chance to take a closer look at SUNN’s new Enduro rig.

The stealth-bomber look with a partially-hidden shock is the true eye catcher of the new carbon frame. The new and very extravagant-looking version of the Kern will go on sale in March 2019.
A broken hand forced Theo Galy to sit out most of the Enduro World Series and the French enduro pro was only able to join his fellow racers on the penultimate appointment of the 2018 EWS season. That’s why he was more than pleased with his 15th place in the Finale Ligure race. As opposed to his team mate Kevin Miguel, Theo rode the SUNN LT 29 Prototype both in Ainsa and at the last race in Italy. His “ready to race” bike weighs 15,65 kg including pedals, multi-tool etc.
Even without the “PROTOTYPE” decal on the seat-stay the new SUNN LT 29 stands out from the crowd — the frame is rather extravagant-looking. The SRAM Eagle 10-50-tooth cassette offers an enormous gear-range — it certainly managed to impress us in our endurance test.

The FAST SUSPENSION Holy Grail-shock hides inside the frame, offers 150 mm of travel and is equipped with a 477 spring. In order to accommodate the shock inside the Horst-Link construction the engineers had to keep the seat tube short.

Of course a French bike asks for French pedals. Theo uses a pair of LOOK’s X-Track pedals.
Theo runs a 750 mm FSA Grid handlebar with 20 mm rise mounted on a 35 mm FSA Grid- stem. He also carries a OneUp Components multitool with CO2 cartridge in the headset.
Theo stores a tubeless repair kit and other bits in a Zefal saddle bag under the DDK Kallum-saddle
Both the front- and rear-wheel come with FSA Afterburner WideR 148 rims with 30 mm inner-width and Hutchinson Toro RR tires. Theo rode the EWS finale with 20 psi in the front wheel and 23 psi in the rear. He also used two Huck Norris protectors in the rear wheel to protect it from punctures whilst the front wheel only had one wheel insert.
Theo brakes on a pair of Formula Cura brakes with 203 mm brake-rotors front and rear. Here you’ll find out how the Formula Cura brakes performed in our big brake comparison test. Theo rides a 160 mm Formula Selva fork which he set up with 56 psi for the Finale Ligure race.
