*100-mile update is at the end of this article.
New for the 2018 Specialized lineup is the Chisel. The Chisel effectively replaces the Specialized Crave as their sub $2,000 hardtail 29er. The main difference between the Chisel and Crave is frame geometry. The Chisel geometry bridges the gap between traditional cross-country geometry and modern trail geometry by offering a head tube angle of 69.8°.
There are three options for the men’s Chisel:
Chisel Expert 1x ($1850)
Chisel Comp 2x ($1500)
Chisel Frameset ($750)
I chose to build up a frameset. Going the route of a frame gives you the option of two colors that are not available as complete builds. All Chisels are built with Specialized’s M5 aluminum.
The frame has internal cable routing, boost spacing, and a threaded bottom bracket shell.
My intentions were to build a lightweight cross-country bike that still felt fun/stable on the descents.
For the fork, I chose the 2018 Fox 32 Step Cast with Kashima Coat.
The fork is light (a hair under 3 lbs). I chose the Fit4 3 Position Damper without the remote lockout. The Fit4 damper offers more adjustment when the fork is in its open position.
The wheels are built around Hope Pro 4 hubs which are high-quality hubs at a relatively affordable price.
I chose Stan’s No Tubes Crest rims which are plenty light and far more affordable than an average carbon rim. The wheels are laced with DT Swiss Competition spokes and purple alloy nipples.
Finishing off the wheels are WTB tubeless valves, Orange Seal rim tape and sealant, and Maxxis 29×2.35 Ikon tires.
The drivetrain consists of a Shimano XT 11-speed 11-46 cassette, KMC X11SL chain,
Shimano XT shifter and derailleur,
Race Face Next SL G4 cranks and a Wolf Tooth 30t oval chainring.
The brakes are Shimano XT with 160mm rotors front and rear.
The cockpit contains a Race Face Next 35 20mm rise 760 width handlebar,
Race Face Turbine 35 stem,
ESI Fit XC grips, Origin8 VEX platform pedals,
Specialized Phenom Expert 143mm saddle, and a KS LEV Integra 27.2 internally routed 100mm travel dropper post.
Finding a 27.2 dropper with a decent amount of travel and internal routing proved to be difficult but this dropper seems up to the challenge thus far.
The Chisel is for a rider looking for a lightweight cross-country rig that is stable enough for fast and challenging descents without totally breaking the bank.
The price gap between the Chisel Comp 2x and Chisel Expert 1x is somewhat negligible. It really just depends on whether you prefer a 1x or 2x drivetrain. Each has its upside and downside. The 1x is clean and simple but lacks the high-end gears that a 2x provides. On the other hand, 2x drivetrains are a little heavier and less pleasing on an aesthetic level.
My particular build retails somewhere around $4,300 with every component at full price. However, If you choose to build up a frame, you should be able to get a shop to give you a break on at least some of your components.
Let me know what you think of the new Specialized Chisel. Also, how about my build? What would you have done differently?
By far the most common inquiry regarding the Chisel is whether or not it will clear a 2.6″ tire. The only 2.6″ tire I currently have access to is the Specialized Purgatory (a great trail tire in my area). Today, after keeping you guys waiting way too long, I put the tire on my rear wheel.
The good news is that it fits with more than enough room to spare.
The bad news is this 2.6″ tire isn’t actually 2.6″. Unfortunately, it measures much closer to a 2.3″.
This is an issue that Specialized is aware of and is planning on correcting this upcoming model year.
I’ve decided to stop here as I still don’t have a definitive answer on whether or not a true 2.6″ tire will fit. As soon as I get my hands on a true 2.6″ tire, I will update this post.
100 MILE UPDATE:
To put it simply, this bike is a rocket.
I expected my climbs to improve in comparison to my Stumpjumper FSR. I expected an improvement because the Chisel weighs 4.5 fewer pounds than my Stumpy. I expected an improvement because the Chisel doesn’t have 150mm of rear suspension. I expected the steeper head tube angle, 29er wheels, and XC geometry to all translate into a much better climber. It came as no surprise that all of my expectations were met.
The Chisel is a climbing machine. On climbs that I averaged speeds between 3-4mph on my Stumpy, I average close to 6mph on the Chisel. The frame is lightweight and stiff in all the right places. I feel that little to no energy is lost on the Chisel and all of my efforts result in the bike moving forward at a fast pace.
The climbing performance alone is enough to sell me on this bike. What I didn’t expect, however, is how much faster I am on the descents. There are a couple factors that should be addressed when considering why I descend faster on the Chisel in comparison to my Stumpy. First of all, I am running 29×2.35 tires on the Chisel and 27.5×2.6 tires on the Stumpy. There is a wider footprint (contact point) with the 2.6 tires which certainly adds rolling resistance. 29er tires also carry momentum better than any other tire size. This is a claim that has been tested and supported by many manufacturers and I can attest to it. Secondly, I feel that my downhill skills are slowly improving and that may be reflected in my times. Take for example the trail I rode most often: Ash Canyon in Carson City, NV. The trail is a great place to work on XC riding. There is a fun downhill section known as Jackrabbit Downhill. This is the section where I really focus on my downhill times as I know the trail very well.
In the picture below, I have highlighted my fasted Jackrabbit Downhill time for both bikes. My fastest time on the Chisel is highlighted in green and my fastest time on the Stumpy is highlighted in blue.
Again, I am becoming a better descender. But do I believe that my skills alone knocked 12 seconds off my best time in only one month? No.
I believe the 29″ tires account for some of the improvement. I also believe my sprinting efficiency on the Chisel is far superior and helped slash my time during brief moments and flat terrain. Whatever the case may be, and feel free to give me your opinion if I’m missing any possibilities, I am stoked with the results. I should mention that long descents on the Chisel aren’t nearly as fun or as comfortable as with the Stumpy. My back tightens up and begins to ache much faster on the chisel. But that’s not much of a concern because I bought the Chisel for one purpose: to go fast. I also had hopes that the Chisel would motivate me to get into shape and try some XC races. The bike has shown that it is fully capable of putting up some competitive XC runs. The only question I have yet to answer is whether or not I am as capable as the bike.
