Simplon claims its Pride II is still the fastest bike on earth – and this custom version certainly looks the part

Well, that's what was claimed in 2021, but this newly built custom edition is surely still fast as!

"If it looks fast it must be fast right?" Ccache – an Australian premium bike shop – typed on its Instagram post showcasing this bespoke Simplon Pride II aero road bike. The bike itself here isn't particularly new, the Pride II was introduced already three years ago and it continues to claim it's the "fastest UCI-compliant road racing bike in the world". But we've taken a little look at what this aero bike is all about, in its popping colourway.

Simplon has focused on making the Pride its most aerodynamic bike for quite a few years now – our very own Tony did a video about the Pride in 2017. The Pride II is the updated version of the bike, and little has remained the same from the earlier model. The Pride II boasts an ever more advanced carbon frame (with a claimed weight of 1,210g), and the fully built bikes claim to weigh anything from 7.5kg upwards. Despite that being a relatively lightweight bike, this is not to be mistaken for a climbing bike. 

In 2021, Simplon said the Pride II broke all wind tunnel records, beating the likes of Cannondale SystemSix Hi-Mod, Canyon Aeroad 2018 and Trek Madone SLR 9. How it would fare against the 2024 models has not been tested, so we can't confirm it'd be still quite as fast against the modern competition, but it's fair to believe that the bike is still pretty fast - perhaps faster than the Cervelo S5 which it bears a lot of aesthetic resemblance to.

The frame boasts minimal air resistance with its drag-optimised tube shapes and the bike is said to make a highly efficient use of the sail effect for maximum propulsion (forward movement). For amateur riders the benefits of all this are likely very marginal, but at top speeds over long-distance rides, those benefits compound even at medium speed.

As with any modern aero bike, the Pride II of course comes with a custom-designed, proprietary cockpit.The setup neatly (and excruciatingly, if you're a mechanic) hides away all cables and this of course further adds to the aero gains. It is, however, not one-piece like many of the ones seen on 2024 road bikes are, but instead consists of two parts meaning it's easier to tailor for individual riders' needs. There are four options for the flat aero base bar (from 38cm to 44cm), as well as three stem rise heights. In essence, the system allows for 15mm of reach adjustment with each combo. 

And a little bit about the Ccache build here... the custom bike is built with a SRAM Force rear mech with Ceramic speed cage and Force shifters, and a dinner-plate-sized SRAM TT chainring attached to a SRAM Red chainset with a Quorc powermeter. There is zero bartape to be seen because… well we don't know why. To save weight?

The deep-section wheels are clad with GP5000 TT TR tyres and the bike is finished with white Look pedals, Selle Italia Boost SLR saddle and a white bottlecage. 

The Simplon Pride II currently retails for 6,399€ (£5,500) and though we don't have the exact price for this specific build, it's likely more than the stock versions from Simplon.

What evidence do we have thats its fast?  And define fast.  Probably a few fractions of a second at Pro power levels.

Fast is pointless when theres a 65kg lump sitting above it and the aerodynamics will be dominated by the Pro's posture.

I love the smell of marketing BS in the morning!

It's fastest in the Tour magazine testing. Who knows whether that applies when being ridden outside.

Tour magazine eh? Are they still at it even after their enormous faceplant with stiffness in the nineties and noughties?
As the German saying goes: Wer viel misst, misst Mist.

What do you think was wrong with their measurements?

Taking some abstract measurements, stiffness then and now aerodynamics (I suppose, I don't read them), that have little or no bearing in real life (and can like high stiffness even be detrimental for many if not most riders) and making them absolute, because they're easy to measure and what's more easily marketable...

There are VERY sizeable drag differences between bikes, even if they're all aero bikes.

Which is why this will probably be beaten by any reasonably laid back recumbent....

Don't know about fastest (surely that depends on who's riding it?), but ugliest they're really getting there.

I think you are faster on it because you are constantly subciously trying to get away from it.

Fugly thing.
