YT Jeffsy 27.5 Frameset MK2 Black Magic

Make your own rollercoaster
If you belong to the type of rider that enjoys sending it down gnarly, techy trails AND collecting hundreds of meters of altitude a day, then JEFFSY will have you covered.

Discover Your YT
It's never too late to try something new and find your passion. That's hardwired into the YT brand, and every bike that they make. Young Talent is what YT stands for. It's inside us all. It's up to each of us to find our young and undiscovered talent, to overcome conventions and pursue our dreams.

Geometry you can't overlook
The JEFFSY comes in 27.5-inch wheel sizes paired with a highly durable aluminium frame.
All models are available in frame sizes S to XXL with a fun-loving DNA and geometry, which can be adjusted thanks to the Flip Chip, which drops the bottom bracket by 8 mm and results in a 0.5-slacker head and seat tube angle. The slack head angle, long reach and low front give riders a comfortably aggressive position on the bike during technical descents and plenty of control, while the steep seat tube angle allows for great climbing characteristics.
