Hed Tech & Safety



Rest Easy - We've got you covered.  HED products are coverd by our 5-year Limited Warranty (a copy of which is attached below for your reference).  For review of a HED product covered under warranty, please fill out HED's Warranty & Repair Request Form here: https://store.hedcycling.com/warranty-repair-request-form/   

For further warranty information, please call us at Dawson Sports on 02 9979 2855 or e-mail us at hed@dawsonsports.com.au

PLEASE NOTE: Any wheels sent to us for warranty or repair must be clean and free of any/all accessories such as tires, tubes, rim tape, cassettes, skewers, axles, disc brake rotors, track lockrings, and reflectors (or there will be a service charge).  We are not responsible for any loss of these accessories.  




We receive a lot (and I mean A LOT) of questions about our wheels, and how to determine which wheel is right for which rider, terrain, weather condition, or style of riding.  Matching the right product to the right intended use is the most important factor for ensuring a long and healthy life both your products AND yourself.  In other words - if you want to make it down the mountain, up the ramp, and over the three flaming school buses, don’t use a lightweight climbing wheel set.  Similarly, if you want to win your local road race, we advise that you not use our 100mm-wide BFD fat bike wheels. 

The chart below will help you determine whether the wheel you're interested in is appropriate and safe for your type of riding.  Of course, we always suggest that your proper wheel choice be paired with proper tire pressure, which we cover in greater depth at www.hedcycling.com/pressure/.

*A Note On Wheels and Impact Damage: For all types of bicycle wheels, a hard strike on the rim is likely to result in rim damage. At or near the point of impact, an aluminum rim will dent, and a carbon rim may delaminate - both are unsafe conditions that require rim replacement.  If your wheel or rim become damaged from impact, please contact us to inquire about our limited Crash Replacement program.


NOTE: Hed does not currently manufacture downhill-specific products, or those intended for downhill racing or other highly aggressive riding



Nothing sets you and your HED wheels up for success like using the optimum tire size and pressure – regardless of whether you’re riding on a road, trail, or snow-covered field.  This page will help to guide you to the proper pressure for your bike based on the tire size, type of terrain, and your body weight.  

Please note that this only serves as a guideline, and your individual terrain, riding style, body weight, weather, and preferences will ultimately dictate the best pressure.  HED is not responsible for rim damage due to tire pressure that is too high or too low.  Also note that MAXIMUM pressure and recommended pressure are not the same thing, and inflating your tires to the maximum pressure will typically result in a reduction in ride quality, safety, and overall speed.


*NOTE: For 25mm-wide clincher aero disc wheels (Jet Plus Disc, Jet Disc BLACK, Jet Disc^2, the maximum tire pressure with TUBELESS tires is 80psi.  Max PSI value is for the narrowest tire listed.  For wider tires run lower PSI





***Adding pressure for body weight:

Our charts are intended as a baseline, but must be adjusted for rider body weight.  If the tire pressure is too low, the rim can bottom out on the ground, potentially causing damage and an unsafe riding condition. 

For every 20lbs of rider body weight beyond the maximum on our charts – 

  • Add 5psi for road tires (25 - 30mm inflated width)
  • Add 2psi for MTB tires (2.0 – 3.0” inflated width)
  • Add 1psi for fat tires (3.8 – 5.0” inflated width)
  • Never exceed the maximum tire pressure of either your tire or rim (whichever is lower)


true-speed-2-27-18.jpgFor over 25 years, Steve Hed spent his energy developing the best cycling equipment available. When it came to wheels, the end goal was simply to make them as fast as possible. It may sound easy, but the journey to building the world's fastest wheels is complicated, and ever-changing. In the pursuit of speed, Steve continually pushed the envelope to its fullest; no stone left unturned. Hed is known for building the world's most aerodynamic wheels, a title that all wheel companies wish they could claim.  Most people do not realize that Hed goes a lot further than just aerodynamics to bring you the fastest wheels on earth. Other important issues such as tire performance, stability in crosswinds, lateral stiffness, drivetrain efficiency, durability, comfort, quality control, carbon fiber manipulation, and weight are also carefully considered. Each wheel addresses these aspects in different ways, and this is truly where science meets art – and True Speed was born.

Back in 1984, Steve Hed started his company building aerodynamic disc wheels. At that time, Hed was the only company able to make them affordable to the average person. With his wind tunnel experience and deep manufacturing knowledge, it became obvious to Steve that his disc wheel provided a huge aerodynamic advantage. Using them as a front wheel, however, created steering problems that could be dangerous in windy conditions. In order to solve this problem, Steve invented the deep section carbon wheel that we all see today. In hindsight, this seems like a simple solution, but back in the 80's it was revolutionary.



Steve's understanding of how airflow interacts with wheels led to further improvement and innovation. While other companies talk about aerodynamics, Steve Hed mastered it. Through the years, he accumulated more than 200 days in the wind tunnel and this knowledge goes into every wheel. Year after year, bike magazines, pro tour teams, and amateur athletes do their own testing in the wind tunnel and on the track to verify what we already know: that Hed wheels are still the world's most aerodynamic.



In 2006, Steve became dissatisfied with the interaction between the rim and the tire. By this time, the 23mm tire had become the standard choice for nearly every cyclist. However, Steve noticed that combining a wider tire with a narrow rim simply did not make any sense. Aerodynamically, the narrow 19mm rim of that era combined with a 23mm tire created a tire profile that was light bulb-shaped - this is not very efficient and leads to increased wind drag. Steve invented a solution and Hed's C2 technology was born – widening the rim to 23mm to match the tire. By making the rim edge wider, C2 allows the tire to flow almost perfectly into the rim shape, ushering in a revolutionary step forward in aerodynamic performance.

Some other manufacturers took note and began to use 23mm-wide rims in their wheels over time. Knowing that there was still more speed on the table, Steve and the engineers at Hed were already hard at work on the next innovation. It debuted in 2013, and is called Plus rim technology. Using an all-new 25mm-wide rim, this completely shattered the mold for what’s expected out of road, time trial, and gravel wheels. Plus rims take everything that C2 did, and does it better – better aerodynamics, better lateral stiffness, better ride quality, better tire shaping, and better handling. Plus rims also allow for lower tire pressure, allowing for even more comfort and rolling speed than the benchmark C2.



Steve Hed's follow-up to C2 technology was Stability Control Technology (SCT). Anyone can design a wheel that is fast while riding straight into the wind. Making one that is excellent in all wind conditions, which is what riders deal with most of the time, is quite different. With the newly-found aerodynamics that the C2 platform provides, Steve engineered how to tame the stability of a wheel in crosswind situations. After all, what good does superior aerodynamic performance do for a cyclist if they are not able to control their wheel? The resulting SCT design is yet another Hed-invented technology that has revolutionized overall wheel performance. The knowledge and design technique involved in the SCT design is Hed's most heavily guarded secret. Recreational cyclists confirm SCT's effectiveness after just one windy day in the saddle. Professional cyclists confirm it daily by their numerous victories throughout the season.




The properties of carbon fiber can be tailored and modified to your advantage if you have the expertise. Hed has known this for decades, and constantly improves their designs by tweaking and revising this process. By fine-tuning the resins, layup schedules, and fiber orientation we can manipulate a wheel's comfort, strength, and weight while maintaining its lateral stiffness. Although this creates extra steps in the production process, the advantages these processes create are astounding. After one good ride on our wheels you will find that this extra effort is worth it.



Steve Hed loved to talk about quality control and was been in business long enough to know its importance. Steve was often heard saying, "Don't confuse technology with execution." In other words, no matter how good your design is, the execution of the design is just as important. This is why every Hed wheel goes through a rigorous quality control program. This QC begins at the individual component level. Every rim, hub, spoke, bearing, and nipple goes through a painstakingly meticulous inspection before they are built into our wheels. We also require each wheel to be built to our strict standards. Spoke tension as well as trueness in both axial and radial directions are measured and recorded with every wheel. This level of precision is crucial to deliver the finest wheels that have ever been built.



While weight is a factor in True Speed, it is one of the smallest influences. Each of our wheels is a particular weight because of the performance that is engineered into it. We do not set out to hit a target weight with any particular wheel; we build wheels to perform properly and reliably. In some (but certainly not all) cases this means that our wheels weigh just a bit more than our competitors' wheels. Nonetheless, the small amount of extra weight in our wheels is there to ensure that we hit our parameters for lateral stiffness, drive train efficiency, durability, and fatigue resistance. When weight adds stiffness, for example, you expend fewer watts pedaling. When you compare this watt efficiency to the savings you achieve from reducing the weight of a flexible wheel, you find that a little weight and stiffness wins out by a wide margin. Know that when you ride a Hed wheel, every gram is there for a reason.
