Name: Stromm Track Frame
SKU: 20333
Availability: InStock

The Stromm track frame takes full advantage of the new UCI rules surrounding tube shapes and rider positioning combined with new carbon manufacturing techniques to produce the fastest bike on the boards.

Cycling has changed a lot in the last decade. We want a bike design that keeps up with athletes’ innovation on the track. It’s time for the bike you ride to keep up with these advancements.

No More 3:1

The UCI has lifted the decades-old 3:1 tube shape ratio restriction giving engineers room to create shapes with 600%+ lower drag sectionally than before. Stromm is the first bike to take full advantage of this new rule change.

Long and Narrow

The age of brute-force speed is over. The Stromm is optimized for a modern, long and narrow rider position to go faster for longer.

System Optimized Aerodynamics

When is the last time your bike did a lap without you? The Stromm is designed to be the fastest when it has a rider on it: minimize the system drag of a rider on the bicycle:

Sloping top tube and seat post design creates vortices that keep air attached to rider’s back longer delaying separation and turbulence and reducing drag
Fork and seatstays encourage better airflow over rider’s legs
Seat tube creates propulsive lift when in the influence of rider’s legs
Wide fork and seatstay minimize effects of wheel differences – any well-designed wheel is fast with this frame

The fork is super wide to prevent interference drag from the wheel. It is “wheel-agnostic” and faster than bikes with narrow forks paired with wheels like Hed 3, Corima 4 Spoke, Mavic Io, etc. In addition, it also shapes the air around the rider’s legs—one of the biggest sources of drag in the entire rider-bike system.

Fast inside and out

Tube shapes are designed to harness laminar flow that exists indoors to create maximum speed.

The frame’s airfoils also perform in more turbulent outdoor flow to minimize gust-dependence and use crosswinds to create thrust.

The Fork

Difficult to design, even harder to manufacture, forks are the leading edge and the backbone of an aerodynamic system. The Stromm fork employs new techniques in carbon manufacturing to take maximum advantage of the new UCI rules.

Toray Composites

We’re exclusively using Toray Composite carbon to ensure we are getting exactly the performance we need from each piece. Strong, resilient fibers where needed. Stiff fabric in key areas, and the resin systems to optimize the combination of materials.

It is common in carbon fiber manufacturing to use “house blend” carbon with far less quality control and no certification process. What’s more is the resin systems are often less optimal resulting in resin-rich end products yielding inconsistent quality. You end up with less control and precision over stiffness, durability, and material optimization.

Additionally we’ve taken the extra step to develop internal molds, mandrels, and pre-formed shapes that can dictate precise shape, compression, and wall thicknesses throughout the frame and fork.

Use your standard components

The seat post has to be proprietary for optimized aerodynamic tube-shape, but everything else uses conventional track industry standards. Use whatever parts you love, find replacements easily, travel with confidence and generally be a happier athlete.
1.125 steerer, IS41 bearings for easy compatibility with any stem
Standard 9mm x 100mm front and 10mm x 120mm rear track axles
68mm threaded bottom bracket

Frame details:

We want this bike for ourselves, too, so we’re making the bike we want:

Long, replaceable rear dropouts with adjusters, no tiny hex key needed
Stiffness bench-marked to existing world-class frames
Extra, woven carbon in areas of high impact/fragility (e.g. top tube where you may get handlebar strike, seat stays where you could crush in airport bag, etc.)
Aluminum glued insert & star nut: no more worries about incorrectly installed steer plug. All forks come cut to size with a glued aluminum plug & star nut.
Seatpost has large range of adjustment that should allow all fits
Room for 28mm tires, wide lenticular disc wheels
Fits up to a 70T chainring
