KIBO FRAME & FORKS
The Kibo 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 725, and the fork blades Reynolds 631.
Over the last 20 years steel has progressed from cheaper chromoly such as the base level Reynolds 525. Reynolds 631 is significantly stronger which is essential for an an expedition bike such as the Kibo.
We also use lugs, proven to be the strongest form of frame join. In terms of looks, nothing quite compares to lugs for that handmade frame aesthetic.
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. We also heat treat the steerer tube from the fork - in fact Reynolds do this for us and noone else - we do this as we know from frame testing that the steerer tube undergoes a lot of stress, particularly on rough ground with loaded panniers. The Reynolds 725 seatstays we use are also unique to Stanforth Bikes, providing more strength than other 725 stays in the Reynolds range. It's this attention to detail that sets us apart. The frame is also double butted for extra strength at the joins.
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.
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.
The frame and forks have bosses for three bottle cages, a front low rider rack and rear pannier rack, as well as mudguards.
We also do a version of the Kibo frame with guides and mounts for disc brakes.
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.
