The Flint 28" Gravel frameset with Kol fork by bc original - The perfect combination for your gravel road adventure


The bc original Flint, already known as a versatile gravel bike frame with generous tyre clearance, has found the perfect complement in the bc original Kol carbon gravel fork. The Kol is an all-round model that impresses with its safety, low weight and numerous bikepacking accessories. With its simple and functional design, it ideally matches the classic look of the Flint, which offers you a modern foundation for gravel road adventures. Thanks to a 70° head tube angle, even more difficult descents are manageable. Toe-overlap, i.e. contact between the toe and the front wheel when turning in, does not occur even with thick 28" tyres and fenders. Speaking of tyre clearance: tyres up to 45 mm wide at the rear and even up to 50 mm wide at the front are possible. In addition, the compact design of the frame with a bottom bracket drop of 55 mm prevents you from pedalling in narrow, gnarly terrain. This way, your bike always retains its agility and you benefit from the direct propulsion of the high-quality aluminium chassis on both short and long distances. This makes for more riding fun and comfort!
In the second generation, the Flint frame features a third bottle cage mount, a revised head tube and improved brake hose routing. The fender and pannier rack eyelets are tried and tested, making this frame suitable for commuting and bikepacking. A Cane Creek headset, a BSA bottom bracket and a seat clamp with integrated dust protection round out the frameset and make it a low-maintenance companion. As you probably know, the name " Flint" is an allusion to the flint that used to be mined from the Lousberg in Aachen, Germany. Behind the name " Kol" is the Middle High German word " kol" for " carbon" , which is a reference to the fork's carbon fibre material.

Mein traum Gravelbike.
Ich war auf der Suche nach einem verlässlichen, schicken Gravel Bike ohne Schnickschnack. Ich habe damit eine Radreise durch die Toscana gemacht und nutze es für den täglichen weg zur Arbeit und regelmäßige Feierabendrunden.

Haltbarkeit und Verlässlichkeit waren mein wichtigstes Kriterium an das Rad und das erfüllt es mit Bravour. Es hat echt Spaß gemacht das Rad aufzubauen, da alles perfekt vorbereitet bei mir ankam und nach einem halben Jahr kann ich mit freuden sagen, kein Knacken, Knarzen oder sonstige Kinderkrankheiten. Ein sehr verlässlicher Begleiter.
