Using a 4130 frame and balanced geometry, Big Dog is our capable all-rounder ready to tackle any trail you fancy. Steel has always been the most compliant material to build frames with, keeping you fresh on the roughest of rides. Big wheels shod with 2.35 tyres maintain traction but also offer faster rolling speeds than smaller wheels. To put it simply, if your rides span from fast loops of your local singletrack to all-day epics, the Big Dog will fit the bill perfectly.
SRAM 12 speed SX Eagle groupset offers a huge range of gears for getting you up any gradient. A clutch derailleur and narrow wide chainring mean the chain will be noise free in rougher terrain. This great drivetrain has been paired with SRAM's Level brakeset, top-flight stopping power combined with great lever ergonomics.
WTB I30 29er Wheels provide fast rolling confidence. Tubeless compatible, the 30mm internal width gives you a wider tyre profile, offering more grip and control. Selcof finishing kit is used throughout the bike, including the wide and stable Enduro6 bars and a short 50mm stem for responsive yet controlled steering.
Rockshox Judy TK forks provide 130mm of plush travel, with a lockout included so you won't be losing out on the climbs. Being an air fork, you can change the air pressure to suit your weight and riding style too.
Selcof MTB: Provided by Selcof, the Enduro 6 handlebar is paired with lightweight and dependable alloy stem and seatpost or Selcof Watchtower dropper post adds capability. The Saddle is Italian made from Selle San Marco
