While carbon often gets all the credit, alloy is far from obsolete, especially the M5 premium aluminum with D'Aluisio Smartweld technology found on the Epic Comp Alloy. It's lightweight, stiff, and can also take a beating. But not only that, you also get a redesigned version of the Brain suspension technology that's made the Epic famous.
Race courses have evolved over the past few years. They're more technical, steeper, and simply more challenging to ride. But instead of quivering in our boots, we saw this as an opportunity to make something special—something that both World Cup athletes and XC riders alike can instantly feel the benefit from. We looked at the sum of parts that make a bike handle well, like the head angle, reach, stack, chainstay length, fork offset, etc., and reevaluated all of it. Increasing the reach made a bike that was more stable at speed and generally more comfortable to ride. Dropper posts? Yep, those fit, and not just a short-travel XC option, but full-length droppers that fit in the 30.9mm seat tube. Head angle? We slacked that out, but not without evaluating the overall handling package. It now lands on a custom offset, 42mm fork that works with the slacker head angle in order to behave itself in tight corners and through switchbacks.
Next comes the redesigned Brain technology, Brain 2.0. The Brain changed the way the bike world looked at suspension, both its inefficiencies and benefits alike. And oh was it good. It won races and put a flag in the ground for us as a true leader in innovation and suspension development, but we knew that we could make it better. Simple physics told us that, by moving the Brain closer to the rear axle, it would be in the most sensitive spot. And after countless hours with the RockShox team, the new Brain became more than just a slight upgrade. It's totally new. Now, it reacts seamlessly to bump forces, it has much more consistent damping performance, and finally, it integrates the hoses into the suspension links. This, in turn, improves oil paths, and it creates an incredibly sleek package that outperforms anything on the market.
At the heart of the construction, you'll find our M5 alloy with the exclusive D'Aluisio Smartweld Technology, which strategically places more welding material where it's needed, resulting in an aluminum bike that's more compliant and considerably stiffer at nearly every tube juncture.
The build of the Epic Comp Alloy is value-packed, featuring an 11-speed SRAM GX groupset, SRAM Level TL brakes, and a Roval Control alloy wheelset. Get ready, because this is going to be Epic.
- The M5 Premium Alloy frame with D'Aluisio Smartweld technology finally brings you all the benefits of alloy, like durability, in a lightweight package.
- A RockShox Reba RL fork soaks up the bumps up front, and features both compression and rebound adjustments.
- An 11-speed SRAM GX groupset handles shifting duties, bringing the convenience of one-by to your XC rig.
Often times, carbon gets all of the attention, but as our Senior Advanced R&D Engineer, Chuck Teixeira, says, "If you haven't ridden an aluminum bike lately, you haven't ridden an aluminum bike." And with its D'Aluisio Smartweld frame, trail-ready geometry, and components designed specifically for female XC riders, the Women's Chisel Expert is no exception.
Traditional welding methods create frame joints by connecting tubes to cylinders, leaving the performance and security of the connection up to the skill of the welder. D'Aluisio (DSW), however, allows us to move the joint away from the area of the highest stress, making for a lighter frameset that's stiff, compliant, and incredibly strong—the optimal characteristics of a hardtail XC rig. So what does this mean for you? You'll be powering up climbs, shredding singletrack, and everything in between on a bike that has you questioning why alloy has gotten such a bad rap.
And to further improve this feel, the Chisel also features our XC 29 geometry which took our previous XC race geo and added some trail DNA to the mix. This equates to a longer top tube, a shortened head tube, and a slacked out front end, the result of which is a tremendous increase in downhill stability, plus a wider fit range. And just as importantly, this doesn't require any sacrifice of climbing proficiency.
The build on this Chisel features a mix of Shimano XT and SLX components, powerful hydraulic disc brakes, and 25-millimeter-wide alloy wheels that are optimized for weight and traction. Even better, almost every component has been tailored specifically for women, from the handlebar width to the crankarm length all the way to our superlative Myth Sport saddle.
- Given its lightweight and ultra-stiff characteristics, M5 aluminum was the natural choice for the frame's construction. And when complemented with our speed-focused Women's XC 29 Geometry, D'Aluisio Smartweld technology, and internal cable routing, you get a bike that compromises nothing in delivering explosive speed, confident handling, and hassle-free maintenance.
- A custom RockShox Reba RL 29 fork offers up 90/100mm of smooth travel, while an easily accessible compression and rebound adjusts permit you to customize the feel according to the terrain at hand.
- SRAM GX handles one-by shifting duties, practically eliminating dropped chains, while also reducing overall bike weight.
