Bombtrack Gravel Bike Hook Ext Sram Rival 11s Matte Grey 2019
What size do you need?
Choosing the right sized bike depends on the type of bike, your height, your riding style, and your preference. A correct fitting bike will be more comfortable, more efficient and more fun to ride
Measure yourself accurately
To get started, measure your height and use the size chart available on each product description.
What to do if you are in between bike sizes?
If you are on the edge of two different bike sizes, don't worry, you'll probably be ok on either size (rather than thinking that one size will be awful and the other will fit). Indeed, bikes are adjustable: the seatpost can slide up and down, the saddle can move backwards and forwards and you can even switch out parts like the stem for different sized ones to help the bike fit better.
Finding out whether or not you should pick a bigger or a smaller frame is sometimes as simple as personal preference, but there are a few simple ways to work out which might suit best:
- If you’re flexible, you might prefer a shorter head tube, so the smaller size might work out better for you. You can use a longer stem to make the reach more comfortable.
- On a bigger bike, the reach to the handlebars will be longer. This means that if you have proportionally longer arms, you might be more comfortable on a bigger frame.

The Bombtrack Hook EXT is a CX and gravel bike, designed to keep on going even when the going gets tough.
650 i/o 700 wheels: more personnality!
Built on the foundations of the original Hook, which had proven itself to be beyond capable having tackled the Transalp (endurance) mountain bike race and coming out totally unfazed. If your sights are set a little lower, its no problem, you can rest assured the capabilities are there, and in the meantime enjoy the ride. Carrying the famous white Dove, the Columbus tubing is recognized around the world for its quality. The Cromor tubing on the Hook 2 is ideally suited to the life of a CX and gravel bike, strong and durable yet light enough to let you perform.
Utilising front and rear 12mm thru-axles benefits the Hook Ext with increased stiffness, enhancing your control especially on rougher ground. Versatility comes as standard, not only in the geometry but also with the rear rack and fender mounts.
- Columbus Cromor, double butted front triangle chosen for its lightweight yet durable properties ideal for CX and gravel rides.
- Full carbon fork with 12mm thru-axle.
- SRAM Rival 1x11 long cage derailleur with 11-42T cassette
