It would be a huge understatement to say that road bikes have come a long way since the 1990s. Wheels are wider, tyres have gone tubeless, bars are narrower, gears are electronic, and braking has moved from rims to discs. But does all that actually make them so much faster and nicer to ride? To compare speed and braking performance, we put a 1993 MBK road bike up against Liam’s Specialized Aethos.

To introduce the bikes, we’re comparing a 1993 MBK with 22mm tyres, box-section wheels, downtube shifters, rim brakes and a Columbus steel frame, weighing 9.77kg.

The modern superbike, meanwhile, is a Specialized Aethos, equipped with Shimano Ultegra Di2, Enve 4.5 wheels with Chris King hubs, TPU inner tubes, Vittoria Corsa Pro 30mm tyres, Favero power pedals and a 36cm Enve SES aero handlebar (measured at the hoods).

Aero

The aerodynamic performance of road bikes has come a long way since the ’90s, and it’s not just about deeper frame tubing. Advances in wheels, handlebars and even tyres have all played a role.

Perhaps the biggest gains, though, come from the rider, with more efficient riding positions, alongside faster clothing and helmets, making a significant difference.

For this test, Liam rode a 3km flat circuit on both bikes. The modern bike completed the effort in 5:50, while the ’90s bike took 6:18 – making the modern setup around 7% quicker over the same distance.

Stopping power

Disc brakes are another major development in modern cycling, so we put both bikes to the test for stopping performance. Liam approached a line at 30kph and braked as hard as possible – with the shortest stopping distance taking the win.

The modern bike came to a stop in 11.5 yards (10.5 metres), while the ’90s bike took nearly double that, stopping in 21 yards (19 metres).

Gears

There are some significant differences in gearing between the two bikes, most notably the move from downtube shifters to controls integrated into the brake levers.

Modern bikes use indexed shifting, meaning each click of the lever – whether mechanical or electronic – moves the derailleur a set distance. That wasn’t always the case. Earlier systems often relied on friction shifting, where the rider had to manually position the lever just right to achieve a clean gear change, particularly on the front derailleur. In the early 1990s, many bikes still relied on friction shifting – although Shimano’s first commercially successful indexed shifting system was available from the mid-80s, and the brand’s STI lever (with both braking and gear shifting performed at the levers) launched in 1990.

Early version of indexed shifting were far from perfect, namely the indexing worked for all of about five minutes… today, however, shifting performance has reached a level of refinement that would have been hard to imagine back then. Even entry-level groupsets like Shimano Cues is better than the top end stuff from the late ’90s.

At the higher end, modern electronic shifting systems take things even further, offering fast, accurate and consistent gear changes with minimal effort. They come at a premium, but in terms of performance, there’s little doubt that today’s technology has the edge, but we know a lot of people, Liam included still have a soft spot for these old friction shifters.

Tech has come a long way since the ’90s. Liam notes that his first bike computer could only tell him how fast he was going – if it was working at all. Today’s devices, like Hammerhead’s Karoo, offer far more functionality.

Along with countless customisable data fields, riders can control music directly from the head unit, meaning there’s no need to pull out a phone to skip tracks. The extensions library, essentially an app store, allows for additional features, such as custom data when using sensors like aero meters.

Liam highlights one simple but highly useful feature: setting custom alerts to remind riders to eat and drink. Many forget to fuel properly, he says, and using this feature can help maintain performance and ride faster.

So, with all of the testing done, unsurprisingly the modern bike was both faster and had a considerably shorter stopping distance. It was Liam’s favourite too, but there’s no denying the beauty of the ’90s bike.
