Does the SuperWheel REALLY offer power assistance without a battery? Plus Hunt’s new lightweight alloy wheels, prototype Cadex superbike, Black Inc’s fastest ever disc wheel + more

Catch up with all of this week’s big – and not so big – bike and equipment news

Here are this week’s tech highlights including a deeper look at a wheel that's said to turn your weight in the saddle into forward movement, news about Hunt’s lightweight Alloy SL Disc wheels, Colnago’s TT1 speed weapon that’s also sporting some prototype Campagnolo components, La Passione’s jerseys, Koo’s sunnies, and more. As always, there are some stunning custom finishes to check out too…

“Pedal assistance without a battery” – but does the SuperWheel REALLY work?

The SuperWheel – which we reported on the Live Blog months ago – has been doing the rounds in the media again, which prompted us to get a scientist involved to check out the claims surrounding it.

“Can this spring-powered bicycle ‘SuperWheel’ work on cars to save gas?” MotorBiscuit asked earlier in the week, while Designboom reported that “Spring-powered ‘SuperWheel’ prototype converts cyclist's weight into propulsion”.

If you’re not up to speed with SuperWheel, the idea is that you can “transform your bike to a high-performance bicycle... and experience the freedom of Easy Cycling without the range and speed limit of an electric bike”, according to the claims. 


“This is the new way of pedal assistance without a battery,” says the inventor. “SuperWheel is the practical and convenient alternative to the electric power assistance. Whether you are a city commuter or simply for recreational use, the SuperWheel provides you with the additional power for easy cycling and allows you to enjoy cycling without the hard work.

“Superwheel is a bicycle wheel with a built-in power assistance system, using our patent-pending (WTECT) weight (mass) to energy conversion technology [to] transform the user’s weight to turning power during rotation to improve cycling efficiency.”

The patent does now exist

SuperWheel claims an efficiency improvement of more than 30% compared with a standard wheel.

This video explains how it’s said to work:

Rather than relying on our own assessment, we asked Dr Robert Kelly, a science teacher at Okehampton College with a PhD in physics, what he thought.

“There’s nothing of merit in this,” he said. “My initial scepticism is only heightened by the lack of any proper explanation. 

“Essentially, it looks like they’re saying that due to compression of the springs at the top of the wheel due to the rider’s weight, followed by a decompression as the wheel undergoes its first revolution, there is an extra force that is converted to forward motion. 

“That’s fine on first push off if you got the technique right, but once the wheel is in motion there simply cannot be any continuous gain. 

“If a rider was to then effectively reduce his/her weight on the bike, effectively doing a little jump to lift off the pedals and back down again, you could benefit from the push effect again, but in stable, level riding there’s no gain here. 

“It may be that on riding over hills there is a little ‘bounce’ that happens as you push down on the pedals, so there could be some small continuous gain uphill – but probably only for riders who pedal inefficiently. 

“The 30% energy recovery or equivalent to an e-bike claims must just be wildly exaggerated.”

Hunt unveils lightweight Alloy SL Disc wheels

Hunt has expanded its range with new Alloy SL Disc wheels that are designed to be lightweight and responsive at a reasonable price.

2022 Hunt Alloy SL Disc wheels - 1

The 6061-T6 heat-treated alloy rims are 25mm deep with a 19mm internal width. 

"They're asymmetric and V-shaped in profile, which remains the best option when strength and weight are the priorities," says Hunt.

The rims are tubeless-ready and are laced with triple-butted, straight-pull spokes to Hunt's Sprint SL hubs. The hub shells are made from 6066 heat-treated alloy and the rear wheel engages in 7.5°.

Hunt claims a wheelset weight of 1,443g.

The Hunt Alloy SL Disc wheels are available with various different freehub options at £439.

Check out Colnago’s TT1 speed weapon, complete with prototype Campagnolo components

2022 Colnago TT1 - 1 (1).jpeg

Colnago's prototype TT1 time trial bike certainly looks fast and the Italian brand says that it says offers greater aerodynamic efficiency than the previous K.One. It’ll be raced by UAE Team Emirates in the Giro d’Italia.

The TT1 is the first Colnago time trial bike to use disc brakes. 

“The choice guarantees the best routing of the hydraulic hoses inside the frame with better braking performance and greater rigidity of the entire bicycle thanks to the use of thru-axles on the wheels,” says Colnago. “The weight difference [from the] K.One is minimal while delivering better overall braking performance and safety.”

2022 Colnago TT1 prototype - 1 (1)

The Campagnolo brake lever controls are prototypes, as are the 80mm deep front wheel and rear disc wheel.

The TT1 uses a bayonet fork – the steerer is external – to reduce the frontal impact of the frame, and a monocoque carbon fibre base bar.

It also features a bottle holder and bottle kit incorporated into the aerodynamics of the entire frame. The 500ml bottle is still a 3D printed prototype and will be developed in collaboration with Elite.

2022 Colnago TT1 prototype - 2

Colnago has gone for a very short head tube and a tall stack of spacers under each elbow rest to get the correct riding position. It says that this approach offers less drag than “a more voluminous frame”.

The top tube is horizontal, as are the seatstays along half of their length before kinking down towards the dropouts. 

Colnago says that the TT1, designed exclusively for electronic groupsets, will be modified further before going on sale to the public in autumn 2022.

Black Inc unveils its fastest ever disc wheel

2022 Black Inc Zero wheel - 1.jpeg

Sticking with time trialling, Black Inc has launched its new carbon fibre Zero disc wheel which is set to make its debut on Stage 2 of the Giro d’Italia after the testing of three prototypes over the past year.

Black Inc says that the Zero’s lenticular (curved face) shape is key to its performance. 

2022 Black Inc Zero wheel - 2.jpeg

"The wheel’s drive side utilises a ‘virtual 100mm rim’ design with a striking flat centre section to allow the uninhibited operation of the bike’s rear transmission," says Black Inc. "The non-drive side, meanwhile, pushes the boundaries of wheel aerodynamics with a lenticular disc profile that challenges industry conventions on design and manufacturing."

Black Inc says that the shape "has been proven to generate as much as 20 watts of ‘thrust’ for the rider when fully sailing at yaw".

The Zero has a tubeless-compatible rim with a 21mm inner width and is aerodynamically optimised for a 26.2mm tyre. The claimed weight is 1,188g.

The new Black Inc Zero is available now at £1,883.

Cannondale WorldTeams shift to compostable bottles

Do you know how many times pro cycling teams use each water bottle? Once.

2022 Cannondale compostable bottle - 1

Whenever we’ve asked them why they’ve said that washing and reusing water bottles adds the possibility of passing germs around the team. Plus, giving the bottles away is a form of promotion.

This means that EF Pro Cycling uses 34,000 bottles per year. The pro peloton as a whole uses 630,000.

2022 Cannondale compostable bottle - 2

From now onwards, the Cannondale professional World Tour teams will be using a 100% compostable water bottle. It’s made from plant-derived materials and is free from plasticisers, heavy metals and BPAs (the industrial chemical bisphenol A).

The bottle will disintegrate within three months in an industrial compost system, or 10-12 months in home compost systems.

I really must write up the rant I've had in my head for a couple of years about how Covid-19 is a lightweight and we need a plague that wipes out 99% of the human race.

Is the cadex missing the top tube so that one can now ride it in long flowing skirts?
