Italian brand Fasten has announced that you can now pre-order bikes featuring its Switch Wheel System (SWS), which makes front and rear wheels interchangeable and allows for ultra-fast wheel changes with the disc brake rotor and cassette remaining attached to the frame.
You might remember that we told you about Fasten last year. Check out that story for a full explanation of the concept, along with the benefits Fasten promises.
> Could the Fasten Switch Wheel System revolutionise wheel design?
Fasten says, “SWS is an innovative system born from the need to simplify the world of cycling by making wheel changes easier, faster, and safer than ever. With this new system, there’s no more fiddling with the chain or adjusting the brake disc: with SWS, you can change wheels in seconds, without getting dirty and without compromising the bike’s performance.”
When you remove the rear wheel, the disc brake rotor and cassette remain attached to the frame. You change the wheel without touching the transmission or braking system.
There’s loads more about how SWS works here.
SWS requires specifically designed framesets with bearings integrated into the chainstays and fork. When we ran our story last year, Fasten said it was “working with several manufacturers to integrate SWS into the next generation frames”.

Now, though, Fasten has announced its own bikes – with the Switch Wheel System at the heart of things, of course – which are available to pre-order.
There are three platforms: the Fasten Light, the Fasten Aero, and the Fasten Gravel. The model names pretty much speak for themselves.

Although Fasten doesn’t give a weight for the Light, it’s a disc brake, thru axle frameset that can be built up with Shimano (105 Di2, Ultegra Di2, Dura-Ace Di2) or SRAM (Rival AXS, Force AXS, Red AXS) components and a choice of SWS wheels.
You can choose between 40mm and 50mm carbon rims, and wavy rims that vary in depth from 45mm to 50mm. Fasten claims a weight of 610g for its Carbon Road 40 wheel
Complete Fasten Light bike prices start at €6,090.
The Fasten Aero is available in the same builds with prices starting at €5,990.
The Fasten Gravel comes built up with Shimano GRX or SRAM XPLR groupsets and 35mm-deep SWS Carbon Gravel 35 wheels. Prices start at €4,990.

I’m going to go out on a limb here and predict that we will next see this concept in a cycling museum.
Hmm. Interesting, but I think it’s a solution in search of a problem.
It would great for neutral service in the Pelaton IF it is universally adopted…
It’s taken the bike industry more than a century to agree on a universal derailleur hanger standard, I wouldn’t hold my breath…
Not sure I agree with that, firstly it is not universal yet despite its optimistic name and secondly a separate derailleur hanger has only been needed since frames became weaker than derailleurs, proper steel frames had one build into the dropout and if it ever did get bent it could be bent back straight.
OK then, it’s taken them fifty years to partially start using a UDH. Changes can take a long time in the bike industry, was my point.
Assuming the product is patented, the standard will never be universally adopted. And even if – by some miracle – this happened, the demand would never make the product viable business-wise.
And by the way, who would actually want the same spoke count on both wheels?!
Talking of such things, I think I saw an inious grenadier yesterday, in orange.
Well that’s certainly innovative. Think I’ll stick with the usual arrangement of one at each end though.
So somebody has reinvented the Cinelli Bivalent hubs from six decades ago.

If it offers no disadvantages (no performance, reliability or significant weight penalties) then I don’t know why this wouldn’t be a good thing
Well there’s the total incompatibility with any other bike for a start and the total incompatibility of any bike made for them with any other wheelset…and what real world advantages does it offer? Very slightly faster wheel changes, really relevant only to racers and even then only to racers at a high enough level that they have a mechanic car following. I can already change a wheel in seconds, I don’t mind getting my hands dirty and I’ve always found discs slot right in without needing adjustment. Can’t see it as good for anything but manufacturer profits (if it catches on) myself.
I always enjoy seeing innovative ideas, even if I agree this one seems doomed.
I certainly think there is no chance of anyone buying their bikes based on the information currently available on their website. It’s almost laughable how little information there is about the actual bikes, although I enjoyed the “Performance Indicators” (apparently all three of their models have exactly 95% Elegance).
