YT Industries have just released a trail bike for young shredders! The YT JEFFSY PRIMUS is available in both 24″ and 26″ models and features an aggressive geometry and well-thought-out spec. If your kids are watching you read this, you might want to stop here before they convince you to cash out on one. If not, read on for YT’s official press release!

YT JEFFSY PRIMUS JP 26 | 140 mm | 26″ | 14.2 kg | € 1,999

Having an eye on Young Talent has been a major part of YT’s DNA since the very beginning. Signing Vali Höll to a development contract back in the day was already an early indication of YT’s dedication to junior athletes. Seven years later YT has welcomed a new Young Talent to the YT Family: Harry Schofield. The Brit is one of the biggest talents two-wheel sports has to offer and he already had the chance to send it on the JEFFSY PRIMUS. The 24’’ and 26’’ inch bike is aimed at short shredders with 135cm-150cm and 145cm-160cm in height respectively.

Geometry and spec of the YT JEFFSY PRIMUS

Riders looking to step into gravity mountain biking need bikes that accommodate their needs. So, YT has equipped the JEFFSY PRIMUS with a rear shock with custom tune for lighter riders and also chosen handlebars, grips, saddles and seat posts, that deliver the goods, so that the smallest mountain bikers can get the most out of their ride. Depending on the position of the Flip Chip both the 24’’ and 26’’ JEFFSY PRIMUS have a geometry boasting a slack head angle of 65.5°/66° for a comfortable yet truly aggressive position on the bike while ensuring a smooth ride and allowing for easy handling with plenty of style. Additionally, the aluminium frames have overcome the same testing procedures as all other YT bikes, ensuring maximum stability and reliability. This extremely playful performance bike has been developed with small shredders in mind and aims to enable them to go full send with their big buddies on the trails while proving to be an excellent climber on the way back up.

The JEFFSY PRIMUS JP 24 is spec’d with a mint Manitou Machete JUNIT fork with 130mm worth of travel and its rear counterpart the Manitou McLeod shock is custom tuned for lighter riders. High-end handlebars, grips, saddles and seat post all come from SDG and the 11-speed NX drivetrain from SRAM enables smooth gear changing. The SRAM Guide R brakes with 160mm rotors deliver the braking power to manage speed well before tight corners and come to a halt at the end of the trail to finish with a stoked fist bump with the riding buddies before heading back up again.

The JEFFSY PRIMUS JP 26 has been developed for slightly taller shredders looking to send it with their mates. Fit with a 140 mm Manitou Machete fork and RockShox Deluxe Select + rear shock this mountain bike is a mean machine. The 12-speed SX drivetrain from SRAM paired with SRAM Guide R breaks deliver high performance when it comes to shifting and braking. Handling the bike is a given thanks to ODI grips, E13 handlebars and the dropper post ‘YT Postman’ makes sure the SDG saddle is out of harm’s way when riders hit the next downhill section. Both the JEFFSY PRIMUS JP 24 and 26 rely on MAXXIS Minion DHR II tires to deliver grip in any conditions. Talking of conditions, even the muddiest and wettest days can’t stand in the way of a good shred in the woods, thanks to both bikes boasting the same high-end tech features as the JEFFSY which enable easy maintenance such as the single-sided hardware access and race-specific advanced sealing concept with double-sealed bearings which keep water and dirt at bay.

Our thoughts

The new YT JEFFSY PRIMUS range looks like an absolute dream for young shredders who love pushing the limits and charging hard. The aggressive geometry and sorted spec should translate to great performance on the trail, and to be honest, we wish we could have got our hands on a JEFFSY PRIMUS back when we were kids!
