All our wheels have hooks because it is safer and the tyre can not come off easily.

Hookless run with wider tyres, but are slower in every aspect.

Our wheels are 700cc which is the standard road bike wheel size. Provided you have a standard-sized road bike, then our wheels will fit your bike.

Indeed, converting from rim brakes to disc brakes involves significant effort. It's not just about changing the braking system; you also need new brake calipers, spokes, brake levers, brake cables, brake rotors, and a substantial amount of know-how. Not to mention the many hours you need to invest yourself. Additionally, most rim brake and disc brake wheels differ in terms of spoke count and rim width. Disc brake wheels tend to be much more aerodynamic as they can be wider. Rim brake wheels, on the other hand, have limited width due to the brake pads.

So, it's a complex endeavor, and we do not recommend it. Even professional wheel mechanics wouldn't reuse spokes, let alone the rim itself.

I've also conducted some research that supports our viewpoint, including insights from experts.

The HADRON2 Ultimate/classic 800 are recommended for time trial and triathlon only. The combination of a 625 (front) and 800 (rear) setup is the most recommended for any wind conditions or for those athletes who are sensitive to the wind. At an extreme, the combination of a 500 and 800 setup can also be applied for very challenging wind conditions for very lightweight riders.

The 625s and 485/500s are recommended for road riding. For ultra hilly and changing wind conditions the 485/500s offer more wind stability at the cost of some aero performance. Overall, the fastest solution for the most hilly races is the 625 set. “Aero is King!”

HADRON aero wheels
28mm tyres are the absolute maximum-width tyres you can use on our HADRON aero wheels. In this instance, we would suggest 28mm tyres at the rear and 25mm tyres on the front wheel. For optimal aerodynamic performance, we only recommend using 25mm tyres or less.

HADRON² aero wheels
Tyre sizes of up to 64mm are possible but we advise using tyre sizes between 25mm to 32mm. Our recommended tyre setups are as follows:

• For maximum overall performance: 25mm front and rear, with the option of 28mm on the rear for additional comfort. In general, we recommend this setup for average speeds of 25km/h or higher.
• For increased comfort and for example in training: 28mm front and rear.
• We recommend 8 bar tyre pressure for 25mm tyres and 6bar pressure for 28mm tyres however the maximum tyre manufacturer pressure should be respected and not exceeded.

First of all, make sure the rim tape is intact and is sealed to the rim bed. So there should be no holes, folds, or tears in the tape, especially around the spoke holes. Secondly, check that the tubeless valve is seated well and fastened (not too tight) in place. Then with regards to the tyre itself, important is to lubricate the tyre bead and the rim bed with either some soapy water or some tubeless milk when mounting. Then push the tyre bead out of the rim well (the sunken center part of the rim) as much as possible before inflating. Normally this will be more than enough to get the tyre to seat, even without a compressor.
If all this fails, the tyre tolerances are probably too far on the loose side. To solve this, a second layer of tubeless tape will tighten the assembly and do the trick.

Tyre pressures of 120psi should not be exceeded. The maximum permitted system (bike and rider) weights are:

• HADRON Ultimate Rim Brake: 100kg
• HADRON/HADRON² Ultimate Disc Brake: 110kg
• HADRON Classic Rim Brake: 105kg
• HADRON Classic Disc Brake: 115kg

We recommend only using the following Swiss Side approved brake pads with HADRON² aero wheels: SwissStop Black Prince Flash EVO and SwissStop Black Prince Flash Pro. These are available to buy on our online store. Failure to do so can lead to damage to the wheel and will void the warranty.

When you order the SINC Ceramic Bearings Upgrade Kit, you will receive a User Manual with information on how to install and use the component, as well as how to maintain the component.

We offer our rim brake wheels with a 17mm inner rim width as this is the maximum wheel width we can offer to fit standard rim brake frames and brake callipers.

 When you combine a 17mm wheel with a 25mm tyre you have enough clearance on a typical rim brake frame, for example on a Cervelo A5, at the top of the fork and at the front of the chain stay.

Our wheels offer the best technology available in terms of wheel width on the market, and accordingly are the leading Aero-Dynamic Rim Brake Wheels on the market.

It's important to know that brakes only overheat and potentially cause a blowout if they are continuously and excessively engaged for a prolonged period. You probably are aware that proper braking involves applying them and then releasing gradually, repeating this process throughout the entire descent. Most blowouts occur when the rim overheats due to sustained braking.

You cannot damage the rim by braking; what matters is that during a descent, you avoid constantly keeping the brakes engaged, which would overload the rim.

Disc brake wheels do not come with the lock nut (=disc brake rotor) nor the lock ring. Beacuse this is specific to the bike.

We do not recommend to transfer the bearings from one freehub to a other. You can transfer the Shimano Freehub to the XDR Freehub, but we do not recommend it. Firstly, you are very likely to damage the bearings since they are generally pressed into the Freehub during manufacturing. Secondly, from a performance perspective, you won't gain any advantages by doing this. The only benefit of ceramic bearings is their longer lifespan.
If you intend to upgrade your standard freehub without ceramic bearings, we recommend purchasing a new freehub instead.
