HED Jet TC9 Track Wheelset Info

The HED Jet TC9 Track Wheelset is the deepest option in HED's Jet Track Series — a 90mm front-and-rear clincher built by hand in Roseville, Minnesota for velodrome pursuit, kilometer, and flying start events. Track cycling puts demands on a wheel that road riding doesn't: no coasting, no braking, continuous power transfer through every pedal stroke, and the laterally loaded cornering forces of a banked velodrome at race speed. HED designed the Jet Track Series to meet those demands, drawing from rim technology refined across years of road and triathlon racing and reconfiguring the hub and axle standards for fixed-gear use.

The TC in the name refers to the rim depth, and 9 means 90mm. That's a specific, deliberate choice — not the depth you choose because it's the default or because someone told you deeper is always better. The Jet Track Series comes in three depths: TC4 (38mm), TC6 (60mm), and TC9 (90mm). The TC4 is the most versatile option, suited to mixed training and outdoor track conditions. The TC6 balances aerodynamic efficiency with manageable weight as an all-around choice. The TC9 is designed for the velodrome and essentially only for the velodrome — events where aerodynamic efficiency is the governing variable and where crosswinds, road debris, and variable terrain aren't factors. At the sustained speeds of pursuit and kilometer efforts, a 90mm rim cuts through the air with measurably less resistance than a shallower profile, and in a controlled indoor environment that advantage compounds across every lap.

The rim is built around an alloy base with a bonded carbon aero fairing — a construction that divides the structural and aerodynamic work cleanly. The alloy core handles bead retention, spoke tension, and the repetitive cyclic loading of hard efforts and high-speed banked cornering. The carbon fairing wraps the exterior and delivers the aerodynamic profile. Using an alloy core rather than a full monocoque carbon structure makes the wheel more tolerant of the sustained stress that track racing puts on a rim across a training block and a racing season. The hooked bead design is compatible with any standard clincher tire at up to 80 psi. The TC9 ships without a brake track and is not rim brake compatible — the correct configuration for essentially any modern velodrome setup.

At the hub, HED made specific engineering choices for track applications. The HED Track hub runs on 6001-size stainless steel bearings — a size larger than what most track hubs use — which distributes load over more surface area, lowers rolling resistance, and adds durability under repeated full-gas efforts. The high-flange design shortens effective spoke length between the flange and rim, which reduces lateral flex when you accelerate hard out of a corner or wind up through the final 200 meters of a flying effort. Sapim CX-Ray J-bend spokes laced in a 2-cross pattern complete the assembly. Front axle is 9×1 100mm threaded; rear is 10×1 120mm threaded with standard 1.37"×24tpi fixed cog threading. The lockring thread is 1.29"×24tpi left-hand — the lockring is not included, so factor that into your build.

HED has been building wheels by hand in Minnesota since 1984. The Jet Track Series is built in the same Roseville facility where HED produces their road, gravel, and triathlon wheels — hand-laced and trued on-site, not assembled overseas and shipped back for finishing. At the level the TC9 is designed for, build quality is performance. Consistent spoke tension and a properly trued wheel determine how the wheel responds under high-torque efforts and how it holds up across a full season of racing. The TC9 ships with silver hubs and carries HED's 5-year warranty.

At $1,800, the TC9 is a focused investment for velodrome-specific use. Its 90mm depth, track-threaded hubs, and lack of a brake track make clear that it was designed for one environment. In that environment — pursuit races, kilometer efforts, time trial events on a banked indoor track — it's one of the most aerodynamically capable clincher track wheelsets available, built by a company that has been making performance racing wheels, and only performance racing wheels, for over 40 years.

The RA Perspective

The HED Jet TC9 is the wheel you spec when you're done hedging. The TC4 and TC6 give you options — training, outdoor racing, mixed conditions. The TC9 is a singular choice: maximum aerodynamic depth, track-only hub standards, no brake track. It's a velodrome wheel, and a serious one.

What stands out is how HED has handled the hub. Most track wheels at this price point are sold on rim depth and spoke choice, but the 6001-size bearings in the HED Track hub are a genuine differentiator. Larger bearings mean less rolling resistance under load and longer service life before you notice any degradation — something that matters if you're putting in real velodrome training volume, not just showing up for the occasional race day. The high-flange geometry is equally deliberate: shorter spoke spans translate to a wheel that stays stiffer under the kind of torque a pursuit effort or standing start puts through the drivetrain.

The alloy-plus-carbon-fairing construction is worth understanding before you buy. This isn't a full monocoque carbon rim. The alloy core is what the spoke beds into, what holds the tire bead, what handles the structural load. The carbon fairing is aerodynamic, not structural. That's a more durable long-term design for track use — the alloy core handles cyclic loading better than a carbon rim wall of equivalent weight, and it's more predictable under the kind of stress that sustained velodrome training generates.

Hand-built in Minnesota, 5-year warranty, ships with silver hubs. For riders building a dedicated pursuit or TT setup, the TC9 is the right depth and a properly engineered wheel.
