Wil reviews the Specialized Chisel LTD

Out of all the high-end carbon superbikes, big travel enduro smashers, and fancy electric mountain bikes we get to ride here at Flow, the Specialized Chisel might seem a little, erm, pedestrian in comparison. So it might seem a little strange that when it came time to build up a new bike for myself, I specifically chose an alloy hardtail. The thing is, I really, really like this bike. And there are a few reasons why. Here I’ll be taking you through the custom build behind my Specialized Chisel LTD, and what I love so much about it.

The low weight is fantastic, and being a hardtail it possesses the sort of undiluted responsiveness that full suspension bikes, with their myriad of pivots, bearings and linkages, can only dream about.

Shorts, t-shirt, dusty trails, sunshine and the simple joy of riding a lightweight hardtail. Belissimo!

Why the Specialized Chisel?

Having decided to move on my much-loved Santa Cruz Blur last year, I’d been eyeing up a new XC bike ever since. A hardtail isn’t exactly the logical choice for our local trails, but I had such a good time ripping around on the super-light Canyon Exceed CFR last year that I decided it could actually be a viable option for a personal long-term test bike.

I’m also an absolute sucker for the clean lines, low weight and ease of maintenance of a hardtail. The simplicity is really appealing, so too is the handling. And from the perspective of testing components like wheels, tyres and forks, you don’t get much more high-fidelity feedback than riding a hardtail.

The Specialized Chisel launched in late 2020, gaining attention for its Epic-inspired geometry and the impressive 1,400g claimed frame weight. That is very light, and not that much heavier than many carbon frames. It’s a striking example of how alloy tubes can be manipulated and formed into a lightweight structure that flows and curves in a way that we’re more used to seeing from carbon fibre.

Appealing as it was, the Specialized Chisel only launched in Australia with just the single spec option – the $2,700 AUD Comp. I was contemplating buying the complete bike and stripping it down to the frame to build up my own bike, until I heard a whisper through the grapevine that Specialized would be releasing a small run of limited edition framesets. A few emails later, and I was very fortunate to put my name down for one before they disappeared forever.

Of the four special paint jobs on offer for the Specialized Chisel LTD, this one gets the ‘Air’ finish.

The build kit

Having arrived as a standalone frame, my Specialized Chisel LTD has sprung to life as a custom-built bike. It’s made up of some parts I already had, plus some new bits I sought out specifically for this build. Longer term, it’ll serve as a rotating roster for future test components.

Right now it’s equipped with a 100mm travel RockShox SID SL Ultimate fork. Originally I had it rolling on Hunt Race XC Wide alloy wheels, though they were switched out for a set of high-zoot Crank Brothers Synthesis XCT 11 wheels. These are wrapped with a Schwalbe Racing Ralph/Racing Ray combo. The tyres are 2.35in wide and feature snazzy tan sidewalls, with Tyreinvader inserts fitted front and rear.

The groupset is an all-SRAM affair with a wireless SRAM GX Eagle AXS drivetrain and Level Ultimate brakes. Up top is the new Bontrager RSL one-piece carbon handlebar and stem, a Specialized Power S-Works saddle and the lightweight BikeYoke Divine SL dropper post.

For all the build details, you can check out the full spec list at the bottom of the page.

Wil’s setup his Chisel with a lightweight integrated cockpit from Bontrager that weighs an outrageous 239g.

Any setup tricks or sweet details you’re really into?

No real setup tricks, though I will say I’m a big advocate of running tyre inserts on a hardtail. Those Tyreinvaders only weigh 72g each, but they bring a significant degree of rim and pinch-flat protection to the party, allowing you to get away with slightly lower pressures for a smoother ride. I’m currently running 23psi in the front and 25psi in the rear.

I’m still unsure if the rainbow brake hardware is gaudy or classy, but either way I like the extra dazzle of colour. The titanium rotor bolts are sweet too, and the machined construction of the WolfTooth ReMote dropper post lever is another personal favourite.

Being someone that works on my own bikes, the threaded bottom bracket shell is a boring but much appreciated detail. I also like that the rear brake hose and cables are only routed internally through the downtube. They’re well managed too, with a big alloy plug down at the BB that keeps them snug and secure.

I also love how smoothly the thru-axle head integrates with the dropouts, and how the Stumpjumper-derived chainstay protector effectively dampens chain-slap. It may only be an alloy hardtail, but it’s finished to a really high level.

Specialized Chisel weight

In its current guise, my Specialized Chisel LTD weighs 10.34kg. As usual, that’s weighed without pedals and cages, though it does include the two tyre inserts.

For my fellow weight weenies, here are some of the lightweight highlights from the build;

specialized chisel ltd 2022
Weighing just 1,300g on the dot, the RockShox SID SL is the lightest fork we’ve tested.

Without going into ultra-exotica territory, many of those components are towards the lighter end in their respective categories.

The Crank Brothers wheels don’t break any records, but it’s worth noting that they are built with Industry Nine Hydra hubs, which are relatively heavy. That means the most of the weight is at the centre of the wheelset, with the rims being quite light at 365-375g each (claimed).

Still, if I was really hunting grams, I could drop over 200g with a set of the Roval Control Carbon wheels that Mick has been testing lately. I quite like how the Crank Brothers wheels ride though, so I’ve got some other ideas for gram removal, which I’ll touch on in just a bit.

What do you love about this bike?

I love how clean this bike looks. I dig the paint job, which gives the appearance of being airbrushed. There is a logo underneath the downtube, but from the side you can’t see any branding at all.

The low weight is fantastic, and being a hardtail it possesses the sort of undiluted responsiveness that full suspension bikes, with their myriad of pivots, bearings and linkages, can only dream about. Acceleration is addictively quick, aided by the ridiculous 690 engagement points (!) inside the Industry Nine Hydra rear hub.

However, I think the two attributes that have surprised me most about the Specialized Chisel is just how balanced the handling is, and how comfortable it is given there’s no rear shock.

The Specialized Chisel delivers a highly responsive ride quality, but it’s surprised us with its comfort and control on rougher trails.

I’ve spent time on the latest Specialized Epic HT, and while that’s up there as one of the lightest and most rapid XC bikes I’ve ever ridden, there’s no getting away from the fact that the carbon frame delivers a rather uncompromising ride. Same goes for the Canyon Exceed. In comparison, the Specialized Chisel is decidedly more comfortable, with more give through its slender alloy tubes.

That quality is no doubt enhanced by the Crank Brothers Synthesis XCT 11 wheelset, with the shallow carbon rims helping to dampen high frequency buzz. I’ve ridden a lot of different carbon wheels, and these are up there as some of the smoothest I’ve tested. The slightly narrower rim width (26.5mm front & 24.5mm rear) also gives the tyres a little more spring to their step. Along with the supple Schwalbe casings and tyre inserts, the Chisel is pleasingly adept at rounding off sharper edges on the trail.

While it is very responsive, the use of a 68° head angle and a 44mm fork offset gives it a much calmer temperament compared to the angry race hardtails of old. The 750mm wide bars provide a broad platform up front, and while the dropper only has 80mm of travel, it makes a huge difference for your confidence levels on the descents, while giving you more room to throw the bike around through tight turns.

The RockShox SID SL has terrific small-bump sensitivity for a 100mm fork, but the supportive mid-stroke means it doesn’t dive heavily under hard braking and pronounced weight shifts. Along with the high volume rubber there’s good grip on offer, and minimal pin-balling through rock gardens as a result.

Of course it’s still an XC hardtail, so there’s only so much you can expect when riding much rougher trails. But I’m consistently surprised and impressed with how composed it is on a variety of trail types thanks to the good angles, beautifully refined frame, and considered parts spec.

The supple 2.35in tyres and sensitive fork help to maximise grip, while smoothing off harsher edges on the trail.

What are the best upgrades so far?

Admittedly the build hasn’t changed drastically. I’ve upped the front rotor to 180mm for improved braking power, and I also moved from the Syncros Fraser iC SL integrated cockpit to the Bontrager RSL setup. These are slightly wider at 750mm, and I reckon that’s spot-on for XC riding.

I’ve also recently changed to Ergon GA3 grips, which have been an absolute game-changer. It may seem like a mundane component, but grips are one of the most important contact points with your mountain bike, affecting both comfort and control.

The Ergon GA2 grip offers a mini-wing profile that aims to strike a balance between comfort, support and control.

To begin with I setup the Specialized Chisel with a pair of ODI F-1 Float grips. These are very light at just 86g for the pair, and the squishy silicone foam offers good comfort when riding dirt roads and gentle singletrack. There’s not a lot of absorption on bigger impacts though, and I was finding my palms were suffering on our local rock-laden trails as a result.

In comparison, the Ergon GA3 grips use a lock-on design and are made with a tacky rubber compound. They get a small flared profile with a mini-wing that provides a bigger platform for your palms, and more support for your wrists. There’s actually a bit of squish and flex to each wing, which improves damping further. You still get a high-traction tread pattern, and because the wing is quite small, your fingers can still wrap around uninterrupted. It’s a really nice balance between support and control that allows you to ride with a more relaxed grip. I also like how rotating the grips can help to fine-tune your riding position over the bars.

We’d like another port on this side for routing the rear brake line around the head tube.

What don’t you like about it?

Though the cable routing is pretty well managed, the brake routing is biased for those who run their rear brake on the right side. I’d like to see an additional port so I could route the rear brake hose around the head tube.

Speaking of the brakes, it’s worth noting that the Specialized Chisel will only fit a 2-piston calliper on the rear. I had originally intended to fit a set of SRAM G2 brakes, but the 4-piston calliper wouldn’t physically clear the seatstay tube. Same problem with a 4-piston Shimano SLX calliper. That’s worth bearing in mind for any Chisel owners out there who may be looking into fitting more powerful brakes.

The dropouts are beautifully crafted, though there’s only clearance for 2-piston callipers.

The SRAM GX AXS drivetrain performs well, with the wireless system offering a super clean setup and the 10-52T cassette achieving a huge gear range. That said the rear mech is quite bulky, which is especially noticeable when mounted to such a slender frame. Also, given this is a bike that I’m reaching for in between other test bikes, I like the idea of not having to remember to charge a battery.

For those vanity reasons, and to help drop a few grams, I’m going to swap it out for a cable-activated GX Eagle derailleur and shifter.

Any changes you’re looking to make in the near future?

With the goal of cracking the 10kg weight barrier, next on the upgrade list is a set of carbon cranks. And once the GX Eagle cassette wears out, I’ll look to fit an X01 or XX1 cassette to drop a few more grams while improving shift performance. I intend to seek out the ancient 10-50T ratio, as the 10-52T cassette is overkill for such a lightweight hardtail. Plus, it just looks so big on there!

I’ve also just bought some Torque Caps for the front Industry Nine Hydra hub. These mate up neatly with the Torque Cap dropouts on the SID SL fork to make wheel installation a little quicker, while also providing a stiffer interface between the fork and wheel. A small but sweet upgrade for RockShox users.

While I really like the shape and feel of the Bontrager RSL bars, the integrated look is perhaps a little too futuristic paired to the slender frame tubing. I’m eager to try out a classic 31.8mm handlebar and stem, which will add grams (aargh!) but will also hopefully improve compliance.

I’m also curious about trying a longer fork. The Specialized Chisel frame is rated for up to a 110mm travel fork, which opens the door to fitting a bigger SID with the 35mm upper tubes, or the latest Fox 34 Step-Cast fork. I’d love to see how that affects the handling, though given how much of a hoot this bike has been so far, it’s got a good vibe about it.

Either way, I’m absolutely frothing on the Chisel. The process of making small, incremental upgrades as part of the custom build is so satisfying, especially when it contributes to such a cohesive and well-rounded ride quality.

So what do you folks think of my Specialized Chisel? What do you think we should test out next on this bike? And would you choose to build one up? Or is an alloy hardtail just way too passé for you? Let us know your thoughts in the comments below!

With its highly manipulated alloy frame, progressive geometry and clearance for 2.4in tyres, the Specialized Chisel is a terrific example of the modern XC hardtail.

It may not have a rear shock, adjustable geometry gizmos, or a motor and battery, but that’s kind of the whole point.

Hardtails are no longer the torture devices they used to be – this Specialized Chisel is brilliant!
