Expirience with the YT Jeffsy Core 5

Ludwig Döhl Tattooed models, casual image, good price. That's what YT is always associated with. The Franconians are also placing the new edition of the Jeffsy Core 5 under the motto "Power of Friendship. If you break the marketing slogan down to the technology, it becomes clear: The new Jeffsy does not want to charm its rider with the latest features and trends, but builds on friendly values such as reliability and good nature. Even if the differences to the predecessor are not groundbreaking, the geometry is nevertheless flatter and the storage compartment in the down tube offers space for spare parts for the first time. With a flat 65 degree head tube angle and a long reach, the geometry corresponds to the current trend. The balanced seating position is likely to suite the taste of the majority of bikers. When viewing the 14,9 kg, its apparent: there are lighter All Mountains in this price range. All in all, in the on demanding trails category, you will hardly find a better overall package from parts and geometry. A nice warranty promises sustainability. With 5 years warranty YT sets the bar high!
