Blog for those who want to know more about the "BOMBTRACK HOOK EXT"
Let's check out the details of the HOOK EXT off-road touring bike.
You can also find information about the HOOK EXT on our YouTube channel, so please refer to that as well.
The HOOK EXT is a gravel road bike born to conquer rough roads.
While incorporating road bike components, it can also be fitted with MTB knobby tires, and its sturdy and tough frame makes it a serious bike for both on and off-road adventures.
Furthermore, the details of the frame combine German-style robustness with practicality, making it suitable for weekend activities like camping tours as well as heavy users commuting daily.
For the 2024 model, the HOOK EXT's front fork has undergone a minor change, with the SEIDO MGV gravel fork being adopted.
The MGV gravel fork is a versatile fork that can be used in many ways, and while it is very attractive on its own, it becomes even more user-friendly when combined with the frame.
First, let's check the fork.
◆About the Front Fork
Tire clearance up to 650B x 57C / 700C x 57C is OK!
Frame clearance is 650B x 52C / 700C x 40C.
The fork now allows for significantly wider tires than the frame's maximum capacity.
While the complete bike originally comes with 27.5-inch wheels, future customization could include upgrading just the front fork to a 29-inch for even better off-road performance, essentially allowing for a mullet setup.
Compatible with front racks and low-rider racks, with a load capacity of up to 18kg.
You can attach various racks using the eyelets on the side of the front fork. This allows you to carry anything from tents and sleeping bags to larger bottles and cooking sets.
A noteworthy point is the load capacity of 18kg. I believe there are surprisingly few carbon forks that can withstand this much weight.
Load it up and enjoy your bike trip!
Internal dynamo cable routing is also possible.
On the right side of the front fork, there's a hole for internal cable routing, intended for dynamo lights/hubs. Using this hole allows for a cleaner cable setup.
It's truly a HOOK EXT feature to anticipate practical dynamo lights.
Numerous additional eyelets are also provided.
In addition to these, eyelets are placed everywhere to accommodate various accessories such as full fenders, front lights, and cargo cages.
With so many, almost all commercially available racks should be installable without issue.
You'll be able to fully enjoy future customizations without any installation difficulties.
◆About the Frame
Next, let's examine each part of the frame.
The HOOK EXT uses a sturdy chromoly frame.
Chromoly is one of the materials that BOMBTRACK, a brand that offers adventure bikes, values greatly, and chromoly frames are always used in their main models.
For BOMBTRACK, which proposes riding styles far removed from daily life, such as gravel rides on rough roads, transcontinental journeys with heavy loads, and extraordinarily long rides, sturdy and rugged chromoly frames are an indispensable part of their identity.
Features an extra-thick downtube and bottom bracket.
The HOOK EXT features large-diameter tubing, much like an MTB, and is characterized by quick response during pedaling, resisting twisting and wobbling even off-road.
The bottom bracket adopts the new T47 standard, allowing the use of most spindle diameters currently available. Additionally, a major advantage of T47 is that it is less prone to the "creaking" noise during pedaling compared to traditional press-fit bottom brackets.
Multiple eyelets provided.
Similar to the front fork, there are eyelets on various parts of the frame for attaching accessories.
The seat tube and downtube have three consecutive eyelets, designed to carry heavy loads such as bottles over 1L or tents.
Screw holes are also provided on the seat stays and rear dropouts for easy attachment of rear racks and full fenders.
Compatible with internal dropper seatposts.
The HOOK EXT allows for internal routing of a dropper seatpost cable at the bottom of the seat tube.
Internal routing for rear dynamo cable.
The HOOK EXT allows for internal routing of the rear dynamo cable from the top of the downtube to the rear of the seat tube.
Additionally, a mount for a rear light is pre-positioned on the seat stay.
Among current gravel road bikes, such a strong emphasis on dynamo integration is quite rare, which I believe is a testament to BOMBTRACK's true consideration for practicality and adventure.
BOMBTRACK bikes are highly compatible with dynamo lights, so please consider them when customizing.
Front single or double, the choice is yours!
The HOOK EXT is designed with gravel/road components in mind.
Therefore, it can accommodate common crank sizes such as a 44T single front chainring, or a 50/36T double front chainring.
Even those who feel their gear ratios are insufficient or desire more options will find this adaptable.
