Shimano 105 Di2 R7120 versus SRAM Rival eTap AXS

SRAM took the fight to Shimano in 2021 when it launched Rival eTap AXS – a 12-speed, wireless electronic groupset at a relatively affordable price point. After years of telling us that 105 Di2 wouldn’t happen, Shimano was forced to react and create a rival for Rival eTap AXS. And now it has – Shimano 105 Di2 R7120 launched earlier this year. Having had plenty of time to put both groupsets through their paces, BikeRadar’s senior technical editor, Warren Rossiter, sits down with senior technical writer, Simon von Bromley, to discuss the strengths and weaknesses of each system, and see if they can crown one the king of budget electronic road groupsets.

How MTB racing has influenced bike design

How MTB racing has influenced bike design

The rigours of racing between the tapes demands high performance from both competitors and their bikes, and so the development of bikes, and the components fitted to them, are inextricably linked to racing. At BikeRadar we’re lucky to have two members of the team, Rob Weaver and Luke Marshall, who have competed at World Cup level downhill. They, along with our tech-expert Seb Stott, dig deep in to how the world of racing has, or hasn’t, influenced the design of the modern mountain bike. Hosted on Acast.

MTB Tech Talk | Why do derailleurs still exist?

MTB Tech Talk | Why do derailleurs still exist?

Pretty much since the advent of gears on bicycles, the derailleur has been the dominant mechanism for shifting the chain between gears. However, being dangled by the rear wheel, exposed to the elements, is a risky place to hang out. Internal gear hubs and mechanisms have long been touted as the future of mountain bike drivetrains, yet have never had the impact they’ve promised. Why is that? And what could the future hold for gear shifting on mountain bikes – Seb and Tom discuss. Hosted on Acast. See acast.com/privacy for more information. Learn more about your ad choices.

Do you really need more than one bike?

Do you really need more than one bike?

The ideal number of bikes to own is N + 1 is a popular saying among cyclists – with N representing the number of bikes you already own. But does the new breed of highly versatile, go anywhere road (or gravel) bikes mean that, really, one bike is all you need? Bikeradar’s Tom Marvin, Warren Rossiter and Rob Spedding try to work out if they need to buy more bikes. Hosted on Acast. See acast.com/privacy for more information. Learn more about your ad choices.

MTB Tech Talk | Suspension springs

MTB Tech Talk | Suspension springs

Both your fork and shock rely on their spring to support your weight. This comprises of either a pressurised air spring, or a steel or titanium coil spring. While air springs dominate, for good reasons, it’s not a foregone conclusion as to which may work best for you. Technical Editor Tom Marvin and BikeRadar’s tech guru Seb Stott introduce you to both types, their pros and cons and, ultimately, which you should pick. Hosted on Acast.

MTB Tech Talk | Wheel size

MTB Tech Talk | Wheel size

Debates over wheel size in mountain biking seemingly never end. First there was 26” wheels, then 29er stormed on to the scene – their larger diameter finding fans in the XC world, but older geometries just didn’t work out when travel numbers grew. Then, out of nowhere the 650b wheel arrived and killed off 26” almost instantly. Hosted on Acast. See acast.com/privacy for more information. Learn more about your ad choices.
