Rocky Mountain has released its 2027 Blizzard Carbon, giving us another current production fat-bike as we head toward winter.
The U.S. price is $2,999, with the bike offered in small through XL featuring Rocky Mountain's SMOOTHWALL carbon frame and rigid Rocky Mountain Carbon Fat fork. Rocky lists Shimano Deore, the carbon fork and Tektro four-piston brakes as the headline components.
The frame uses familiar fat-bike standards including a 100 mm threaded BSA bottom bracket and 197 mm rear spacing. It also gets SRAM UDH compatibility, fully guided internal cable routing and dropper-post compatibility.
The drivetrain is Shimano Deore 12-speed with a 10-51 cassette and Rocky Mountain 30-tooth crank. Rocky specifies 165 mm crankarms on small and medium bikes and 170 mm on large and XL. Braking comes from Tektro HD-M5141 hydraulic brakes.
Wheels are built around WTB KOM Light i76 rims. That's a 76 mm internal-width tubeless-compatible rim and a sensible match for a modern 27.5-inch fat-bike setup.
Up front, there's a short 40 mm stem and 780 mm Rocky Mountain handlebar with 38 mm rise. Again, these are contemporary mountain-bike cockpit numbers rather than the longer-stem setups common on earlier fat-bikes.
27.5 x 4.5 Tires... Probably
Here's where the specifications get interesting.
Canadian Rocky Mountain dealer Bosk Vélo Café lists the 2027 Blizzard with Vee Tire Snow Avalanche 27.5 x 4.5 tires, front and rear. They're 120 TPI, folding and tubeless ready.
And Rocky Mountain’s own site specs:
Tires
F: VeeTire Snow Avalanche 27.5 x 4.5 120 TPI SC (Silica Compound) E-25 120TPI FB TLR, All Black color
R: VeeTire Snow Avalanche 27.5 x 4.5 120 TPI SC (Silica Compound) E-25 120TPI FB TLR, All Black color
That makes plenty of sense for a bike intended for winter riding.
The problem is that Rocky Mountain's own current 2027 Blizzard product page says the maximum tire width is 27.5 x 4.0, along with 29 x 3.0.
Meanwhile, Rocky Mountain's Blizzard overview page still discusses 26 x 4.6 tires with room to go larger, along with older Blizzard 10, 20, 30 and 50 model designations. That page seems to contain information carried forward from previous Blizzard generations.
We've contacted Rocky Mountain for clarification.
Until we hear back, we'd consider the 27.5 x 4.5 OE tire specification credible, since it's being published by a Rocky Mountain dealer for this specific 2027 bike, but we wouldn't make assumptions about maximum clearance beyond the stock configuration.
The Geometry Is Familiar
One thing that initially looked new for 2027 turns out to have a longer history.
The Blizzard's current geometry dates back to Rocky Mountain's major redesign for the 2022 model year. At that time the Blizzard moved to a 66-degree head angle and 74-degree seat angle, with a medium reach of 450 mm and a wheelbase of 1,198 mm.
Rocky Mountain still highlights the 66-degree head angle and 74-degree seat angle on its current Blizzard overview and describes the design as "true trail geometry."
So the 2027 Blizzard isn't a new frame geometry story in the same way the recently redesigned Salsa Beargrease is. Instead, it shows that Rocky Mountain is continuing with a design philosophy it adopted several years ago.
In hindsight, Rocky was ahead of the curve.
A Dropper Comes Standard
Another indication of how Rocky Mountain sees the Blizzard being ridden is the inclusion of a dropper post.
Dealer specifications list either an X-Fusion Manic or TranzX adjustable post depending on availability, with travel increasing by frame size: 150 mm on small, 170 mm on medium and 200 mm on large and XL.
That's a substantial amount of dropper travel on a fat-bike and fits neatly with Rocky Mountain's emphasis on trail riding.
Plenty of Mounts
The Blizzard hasn't abandoned utility in pursuit of trail performance.
Rocky Mountain lists 18 mounting points, with 12 on the frame and another six on the fork. That leaves plenty of options for bottles, cargo and winter or adventure setups.
The combination is interesting: carbon frame and fork, 27.5-inch fat-bike wheels, modern trail geometry, a full-length dropper and enough mounting points to build the bike for considerably longer days.
For $2,999, the component package isn't exotic, but Deore 12-speed is proven equipment, the WTB i76 rims are appropriate for the application and the carbon chassis keeps the Blizzard positioned as a serious current fat-bike rather than an old model simply lingering in a catalog.
We're waiting on Rocky Mountain for clarification about the tire specification and whether anything meaningful has changed in the frame itself for 2027.
We'll update this story when we hear back.
