Now in its third iteration, JEFFSY rewrites the rulebook for trail bike performance. Longer, lower, slacker may be a cliche, but here it means control – the Rider Centered Geometry brings absolute balance to your rides, and with the new YT STASH box, we elevate your storage game. No half measures; only Trail Excellence. Get to know the lineup below in our YT JEFFSY CORE range overview.
The YT JEFFSY CORE Range
With five CORE models to choose from, there is a JEFFSY for every budget and style. It’s our first bike to stretch from the budget-brawler CORE 1 level right up to the no-holds-barred CORE 5.
Whichever you choose, know this: Each CORE model provides a level of performance that stretches above and beyond its price point, delivering killer value and trail-ripping prowess for every budget.
Which one you choose is up to you – every JEFFSY features our confidence-inspiring Rider Centered Geometry for unrivaled balance and capability, the all-new Postman V2 dropper post with adjustable travel, and a Thirstmaster 6000 bottle and cage. Carbon models receive the YT STASH downtube storage, and CORE 4 & 5 include a Crankbrothers SOS Tube Stash on-frame storage mount.
Top of the Food Chain: Look no further, this is peak performance. Right down to the finest detail, each component is proven at the highest level, offering an unmatched degree of tuning and quality.
