Hardcore hardtail showing that "steel is real" with new tubing refinements and the same evolved geometry as the other Evo models. The 456 Evo2 brings Dropper Post fit possibilities, with a neater, refined chassis.
Hand welded from DN6 chromoly, this latest incarnation of the 456 continues to evolve for hardtail lovers. That tubing? It's double butted 4130 cromoly steel with tube sections varying from 1.0mm to just 0.6mm in places. We've got our brand new bulge butted seat tube here too, with a 30.9mm ID to take a dropper post if you want it, and shimmed with a brazed on ring reinforcement to take a 34.9mm seat clamp. Front mech size is 34.9mm too if you're running one.
We've also revised the chain stays to have our new asymmetric S bend profile giving huge tyre clearance and chainring clearance, without indents or any other weak points. The frame has an ISCG mount to take a chain guide too.
And finally, we've revised the top tube, to give a better ride. A slimmer, externally butted top tube saves weight whilst adding strength and compliance. And the gussets are in a better position. Result.
Steering geometry, sat static, with an 150mm fork up front the head angle is 65.6 degrees, the seat angle is 71.1 degrees and the BB drop is 11mm. Doesn't make a lot of sense looking at that. So let's look at it with a rider aboard BB sits at 26mm below the wheels, head angle 67.7deg, seat angle 73.2degs. Stable up front, good to descend, good BB height. Also, we've sized the chain stays proportionally, making them 2mm longer on the largest size, which helps stop the front end wheelying about when you're climbing steep stuff. If you're going to ask, 120mm forks give a 67.2deg static head angle and 68.5deg ride height angle, and if you're going to take the 4-5-6 thing to it's extreme and run around with 100mm units, you're looking at a 69deg head angle when you're on the bike. Which is still a whole lot more relaxed than things we rode 10yrs ago.
The head tube remains a standard 1.125in "external" or "normal" or "EC34" type. No fancy pants oversize tapered stuff for this one. Keeping it easy for you to swap over and upgrade.
Colour options are a painted finish, in a lovely "Smoked Paprika" colour, and a raw finished frame, which is clear-coated but does require some cautions The Raw Finish is designed to have manufacturing blemishes and might not appeal to all. Also, it's extremely likely that some degree of surface rusting may be present from new or develop over time, though due to the only process that this frame has been through is the first surface treatment in the paint process, the action of that rust on the frame is only as bad as the action of rust on the inside of a painted frame. The frame is coated with a matt laquer, which being slightly porous will allow the steel tubes to corrode, but this, we consider, gives a patina of age and wear (like a nice wok) rather than it being a problem. If you have an issue with this, please select the painted option.

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.
Correct frame size choice can also depend on a rider’s torso and limb length.
I absolutely love my raw 456. I used to have an aluminium XC machine. I could not imagine how different the ride would feel. The steel is a much more forgiving beast. Where my entire body would be rattling, it just wasn't on the 456. It felt more nimble, more fun. I love the tube sizing, no need for the fat aluminium. It gives the bike a leaner appearance and the tyre clearance is indeed very ample. I run reasonably high volume 2.3 up front and 2.2 out back. I was so excited about getting it that I neglected to weigh it, but it doesn't matter. Fully assembled it doesn't seem much different to the aluminium predecessor. Plus as I mentioned, the handling characteristics are much better so the weight is not an issue at all.I am an absolute convert to steel frames because of this bike, and I will more than likely never ride anything else. I also quite possible will only get me more 456s in the future. An absolute bargain for the price.
