My 2025 YT Jeffsy Core 4 bike is up for sale, with some customised upgrades from the factory.

This bike is truly a one-size-fits-all bike, as it is extremely balanced and efficient on both climbs and descents.

It is in excellent condition, with a completely invisible frame and some extra protection on the bike chain and forks. It has been used for about 5 rides, is brand new, and everything on it is extremely smooth.

Although the Core 4 specs are great, I've added some upgrades that I do for most bikes, such as tyres, cockpit and wheels. This bike needs absolutely nothing and is ready to ride.

Key features:

• V4L Horst Link 145mm suspension
• 29-inch wheels
• HTA 65
• STA 77.9 (effective)
• REACH 475 (large)
• UDH compatible
• Inside frame storage

The size is large (6 feet long, fits me perfectly but there is extra space in both directions)

Frame: Ultra-flexible carbon front and rear triangles; moulded seat stay, chain stay, and bolt-on downtube protection. Inside frame storage

Shock: RockShox Super Deluxe Ultimate, RC2T damper, 210mm length x 55mm stroke

Fork: RockShox Lyrik Ultimate, Charger 3 damper, 44mm offset, 35mm stanchions

Stem: Unite 35mm stem, 35mm clamp

Handlebar: Spank Spike Vibrocore, 40mm rise

Grips: ODI Reflex

Brakes: SRAM Code RSC, 4 pistons, with upgraded SRAM HS2 rotors

Drivetrain: Shimano XT 12-speed mechanical, chain and cranks, with Burgtec chain and SLX cassette.

Seatpost: Brand X 200 mm

Wheel set: Combination of Hunt Trail wide front wheel and Enduro wide rear wheel.

Tyres: Continental Argotal Fr and Kryptotal rear

Saddle: Ergon Sport

Pedals: Not available

If you have any questions, send me a message and I'll be happy to help.

I am happy to ship the bike, but this process is not cheap anywhere. I recently shipped two bikes, and the fully insured shipping cost exceeded £65. Personal collection is preferred at 37 Sea Ln, Ingoldmells, Skegness PE25 1SA.

No exchanges

I am only selling it because I mainly ride cross-country bikes these days and don't need the 150 mm travel.
