Spotted in 2018 ridden by Aaron Gwin, then launched in Feb of 2019, the current 29in YT Tues is now officially 5 years old. That’s the same year that YT launched its Decoy e-bike, which hasn’t received an update either. Has YT’s development team been sitting on its hands for all that time, or did it just get both bikes right, straight out of the gate? Having spent two weeks testing the top-end Tues Core 4 29 in Morzine, France, it’s clearly the latter, even compared to the much younger Propain Rage and Canyon Sender that it’s up against in this three-way DH shootout. YT Tues Core 4 29 need to know Full carbon frame with 200mm travel Available in 29in or 27.5in, but not MX Three size options based on reach Tues Core 4 is the flagship model Fox Factory suspension E13 DH Carbon wheels and 9-21t cassette SRAM Code RSC brakes Zero geometry adjustment Entry level alloy Core 2 £3,499 Frame and geometry Wind the clock back to 2019 when 29er downhill bikes were still being referred to as wagon wheels, and brands were scrambling to get new designs under racers, some hasty designs were more successful than others. Looking at the geometry and sizing of the Tues 29 through a 2024 lens, the numbers haven’t dated one bit. The 62.6º head angle, 349mm BB height and 1,272mm wheelbase on the Regular size Tues 29 puts it right in the mix with the most modern DH bikes. Even the 442mm chainstays are short by current 29er standards. The frame comes in three sizes, Regular, Long and X-Long and all have the same 420mm seat tube height. So essentially you’re sizing for reach and head tube length. And what’s most telling is that even five years on, we opted for the Regular size with its 460mm reach. Yes, that puts us right at the upper limit of YT’s sizing recommendation, but it’s still in line with the dimensions of the size M Canyon Sender, which is the most current bike our Direct Sales Downhill bike test. And it’s a good thing that YT nailed the profile of the carbon Tues first time round. Because there are zero geometry adjustments designed into the frame. So other than raising or lowering the 40mm Kashima coated stanchions in the fork crowns of the Fox 40, you’re stuck with those numbers. There’s also a full 27.5in version of the Tues Core 4, and if anything dates the platform, it’s the distinct absence of an MX build. We’ve seen riders using 27.5in rear wheels, but given that the geometry really is optimised around a 29in rear wheel, you’re going to need some other custom modes to make that work on the current design. Suspension We’ve already mentioned that the Tues does not have hard point geometry adjustments on the frame. But that doesn’t mean you can not manipulate the dynamic geometry and handling of the bike. Best of all you can do so in …Continue reading »

The YT Jeffsy Core 4 is a bike that arrives in a box that is not quite perfect out of the box. BUT... there is loads of potential here.

Is YT the latest brand tempted by the wonders of an elevated main pivot?
