Foundry Cycles recently sent over their brand new Tomahawk carbon fiber hardtail race bike for review. The Tomahawk is an evolution of Foundry’s well-tested Broadaxe 29er hardtail, but rendered in new the Koolaid flavor of 650b.

The Foundry Tomahawk in its native element: fast singletrack

Like the entire Foundry product line, the Tomahawk is constructed from carbon with a matte finish that incorporates understated graphics. The few times I have taken it out so far, it has definitely evoked the, “Dude, what bike is that?” response from other riders encountered on the trail. The “G-3” build that I received features a mix of Shimano drivetrain and brake parts centered around a 2×10 setup. The cockpit bits are alloy components from FSA with grips and a saddle from WTB. The fork is the tried and true Rockshox Reba with a tapered steerer, remote lockout and 15mm axle, and Maxxis Ardent tires maintain contact with the trail.

Quick Specs

  • Fork: Rock Shox Reba 100mm, remote lockout
  • Shifters: Shimano SLX
  • Crankset: Shimano SLX
  • Derailleurs: Shimano XT Shadow +
  • Brakes: Shimano Deore with 160mm Centerlock rotors
  • Wheelset: Stan’s Rapid rims laced to Shimano hubs
  • Cockpit: FSA XC mix
  • Saddle: WTB Silverado
  • Tires: Maxxis Ardent 27.5 x 2.25
  • Weight: 23.50 lbs without pedals, 24.18 with Crank Bros Candy 3

Out of the box, my previously demo’ed Tomahawk was already set up tubeless, and I certainly hope that it ships that way in production. It’s just time for this to be the standard. The bike was quickly assembled, tires inflated, and air fork brought up to pressure, and it needed some fine tuning of the rear shifter’s barrel adjuster to dial in the indexing.

Getting the Foundry Tomahawk Dialed In

Out on the trail

For the full verdict, you’ll need to stay tuned for the final review in a couple of weeks. So far, however, I can tell you that with this bike I have destroyed every Strava PR on every trail segment I have taken it on. It’s hands-down the fastest bike I have ever ridden!

MSRP: $2,050 for frame, $3,175 as built here.

Many thanks to Foundry Cycles for sending the Tomahawk down for review!

    Doesn’t seem that light….but there’s obviously plenty of places to drop weight still. My alloy hardtail 29er with a 3×9 XT drivetrain is just a touch under 25lbs with pedals and bottle cages. But it’s got a some really light wheels, and they’re tubeless. But it’s also a $450 aluminum frame, and the only carbon on the bike is the bars.

      This is actually Foundry’s low-end build kit for this bike. The frame is available as a frame-only, and the high-end build kit features an X01 drivetrain and DT Swiss wheels. I imagine it’s a good bit lighter.

      In response to the wheels, I don’t want to speak for Corey, but I think that’s a place on this bike where you could get some big improvements really quickly by doing an upgrade.

      Also, I got to ride this bike just once, so bear that in mind… but I personally would rather ride Foundry’s Carbon 29er, the Broadaxe, which I reviewed this spring. I haven’t figured out why anyone, unless it’s a very short rider, would want anything smaller than 29″ wheels on a hardtail frame… but I know those people are out there. I just don’t see hardtail XC bikes being a big portion of the 27.5 market.

      Interested to hear Corey’s take on the topic in the final review!!

      The high-end build uses the same Stan’s rims, but DT Swiss hubs.

      “I haven’t figured out why anyone, unless it’s a very short rider, would want anything smaller than 29? wheels on a hardtail frame…”

      Stay tuned. I used to think this way, but this setup is changing my mind!

      Interested to read your final review!

    The fit and geometry seem very similar to my Niner Air 9 carbon, which is also the fastest bike I’ve ever ridden…er…uphill at least. I have it set up XX1 and it is 21lbs with pedals and heavy Nobby Nics, so I am sure you could shave off 3-4 pounds from that bike with the right amount of Visa. Foundry just makes some sweet looking rides….
