KIBO DISC FRAME & FORKS
The Kibo disc frame is hand built in the UK using the strongest gauge of the quality air-hardened British Reynolds 631 steel for the main triangle and chainstays. The seatstays are Reynolds 525, and the forks Reynolds 631. 631 is significantly stronger than Cromoly steel tubing. The frame is also double butted for extra strength at the joins.
The Kibo disc frame differs to the standard Kibo frame in terms of the brake cable guides and routing, the rear dropouts and the addition of the disc mount on the fork blade. We also use stiffer disc specific Reynolds 631 blades on the fork. The disc mounts are IS for a post mount calliper. The dropouts are for a QR hub axle (as are all the Kibo’s).
The specific tubes tubes used on your frame, within the Reynolds 631 range, will be chosen based on your weight and planned load. The tube wall thickness and diameters have a significant bearing on frame stiffness so your frame can be designed specifically with your planned touring in mind.
All of our frames are custom made to best fit you. You can either send us some key measurements or better still, come and visit us for a fitting. The frame will be designed specifically for you, no two frames are the same.
As well as being hand built in the UK, our frame and forks are lugged. We can build fillet brazed versions of the Kibo, just email us on firstname.lastname@example.org to discuss. Please note we don't tig weld as tests have shown joins to be weaker using this process, we braze only with either lugs or by fillet brazing.
We do two frame versions, one for an ahead stem with a 1 1/8" threadless steerer and the other with a 1" threaded steerer for a quill stem. As all of our frames are made to order we can have sloping or horizontal top tubes on either. We also do a step through version.
All of our fork steerers are now heat treated.
The frame and forks have bosses for disc bottle cages, a front low rider rack and rear pannier rack, as well as mudguards.
Why steel? This is an expedition bike so there's only one material suitable for the frame and forks and that's steel. Wherever you are in the world steel frames can be fixed more easily (in the unlikely event that it needs welding...) and on a rigid bike the steel provides a more comfortable ride.
As all of our frames are made to order we will customise the seat tube and top tube lengths to best fit you, either visit us for a fitting or send us your measurements - click here for more info
For heavier riders we can tweak the tube diameters/thicknesses, please get in touch if you'd like to discuss this - click here for more info
All of our frames are supplied with vertical dropouts. Horizontal dropouts can be fitted if preferred.
