BOMBTRACK

Hook EXT

  • Sale
  • Regular price $3,350.00


Smaller wheels, bigger tyres, rowdier personality. The burly Hook EXT is made for the most extreme drop bar adventures. A classic case of "if it ain't broke – don't fix it!". Besides adding a wider, more durable T47 bottom bracket we've revised the cable routing to keep the bike looking clean with any combination of derailleurs and dropper posts. Besides this, the bike retains the same gorgeous matt metallic grey paint scheme and awesome parts list that’s made it a pin-up for many gravel nerds.

Frame with Bombtrack casted drive-side yoke, T47 bottom bracket, extra cage mount under down tube, direct mount top tube ‘fuel’ bag and stealth dropper post routing.

Columbus Cromor, double butted front triangle chosen for its lightweight yet durable properties ideal for CX and gravel rides.

Straight blade extra wide full carbon fork with triple cage mounts and 12mm thru-axle.

FSA GOSSAMER alloy crank with 40T narrow-wide chainring, 11 - 42t cassette and Rival-1 11-speed derailleur,Rival hydraulic brakes.

WTB ST - i21 TCS rims with WTB Nano 2.1” Race folding tires
