Expirience with the YT Jeffsy 29 CORE 4

Ludwig Döhl Uninterrupted fun on the descents combined with the option of coping with longer climbs. That's the promise YT makes with the Jeffsy 29 CORE 4 . With 13,9 kg weight for the complete bike, the YT Fully joins the lighter bikes that you can buy for under under 6000 Euro. Most bikes in its class are heavier. The geometry is moderate and makes for a balanced handling. When it comes to the seating position, YT chooses the middle ground between sporty and comfortable. Finally, here is another killer argument: in price range in alpine terrain, the Jeffsy 29 CORE 4 is one of the best models in the in alpine terrain category. A nice warranty promises sustainability. With 5 years warranty YT sets the bar high!
