YT Industries Jeffsy CF Pro 29

The Jeffsy 27 was released just a bit too late to feature in the 100s this year. No worries though, the Jeffsy 29 still remains one of our favourite trail bikes. It may have slightly less travel but by no means are you bringing a knife to a gun fight, this bike is a true puncher.


In fact, pitching it at 140 with the larger wheels is pretty perfect for a trail bike in our opinion – not too much, not too little, lightweight, inexpensive, fully loaded and… flat out.


This is a bike that will look on your riding with disdain. “Is that all you’ve got?” Don’t be fooled by the big wheels and small travel, we’re still struggling to find its limits. This is a bike that picks up speed like a border collie but charges like a rhino. It takes some stopping even on the burliest trails. It’s delicate to the touch as well though, highly strung and always alert to rider input.

YT were far from the first to produce an agro 29 trail bike but we reckon this has only given them the time to pitch the numbers just right. A 67.6 ° head angle, 1206mm wheelbase and 32mm bottom bracket drop make it eerily similar to a Specialized Stumpjumper, not a bad act to emulate truth be told.

“YT’s march towards global domination continues”

The Jeffsy is bedecked in Fox with a 34 Performance Elite holding things together at the front. It’s a supreme fork but we could just as easily picture this bike with a 150mm 36 to allow it to really plough. The rest of the componentry is just as solid. An Eagle drivetrain only compliments the Jeffsy’s solid climbing performance with extra range.

SRAM Guide brakes, e*thirteen wheelsets, Race Face finishing kit, everything else here has a feeling of ‘deluxe’ but, as usual, the price just doesn’t seem to add up. Pay your €4499 for this and you’ll feel like a criminal.

In fact, all we questioned when we first reviewed the bike was the suspect Onza rubber but with Gwin’s input the brand is sure to be rapidly improving in the coming few years. Similarly, we worried there weren’t enough sizes last year but 2017’s XL addition leaves us really struggling to find criticism. No blingy kashima on the fork and shock? The paint job is less stealthy this time around? That’s really about it.

YT’s march towards global domination continues with the YT Jeffsy, we here at Dirt will be laying out the red carpet in anticipation.
