Electric groupsets: a revolution for cycling
When Shimano introduced its Di2 (Digital Integrated Intelligence) technology in 2009, the concept of electric bike groupsets was hailed as one of theone of the greatest revolutions in the bicycle industry. Like any revolution, it was met with enthusiasm by some and scepticism bycyclists. However, electric bikes have proven to be a delight on every kilometre cycled. Since then, this technology has evolved considerably, notably with the introduction of wireless connectivity, and has even conquered the world of mountain biking. This type of group still has several significant advantages.|>
Faster and more precise gear changes
The main technical advantage of electric groupsets is undoubtedly the speed of gear changes. On theCampagnolo EPS (Electronic Power Shift) rear derailleur, the 11 sprockets on the bike cassette can be shifted 25% faster than on a mechanical bike groupset, and all with a simple flick of the finger. This speed can make all the difference when attacking and accelerating, but also when riding on technical terrain when using an electric group on a mountain bike. But these gear changes are not only faster, they are also more precise. Since the electric derailleurs are controlled electronically, the bike's chain is positionedon the sprockets and chainrings for optimum performance, with clockwork precision. This factor considerably reduces friction in the drivetrain and improves the service life of the groupset components, whether it be the cassette, chainrings or sprockets., whether it be the cassette, the bottom bracket, the derailleur gears or the chain.
Connectivity to a smartphone or bike GPS
Electric groupsets also offer an immersive feature, namely connectivity with a bike GPS or smartphone. This is the case with Shimano Di2 and Campagnolo EPS groupsets. This feature allows you to display the gear ratio, as well as crucial information such as the battery status of the group.
The evolution of automatic transmission
Braking and gear changing are just the beginning of the technological advances made possible by the electric drive train. Researchers at Baron BioSystems are now offering BioShift, a technology that introduces automatic transmission to bicycles. When paired with an electric drive unit, BioShift determines the optimal gear ratio for each situation based on performance and the cyclist's physiological data.When the cyclist feels like a thrill and wants to select gears manually, the automatic transmission function can be deactivated at any time. BioShift also allows manual gear changes, even when the automatic transmission function is engaged.h3 style="font-size: 17px;">Autonomy, an issue that is no longer an issue
While the range of electric drive unit batteries was one of the main sources of scepticism, manufacturers were keen to reassure users. In this regard, a full charge provides a range of 2,000 kilometres on Shimano Di2 units, 1,000 kilometres on SRAM wireless groupsets and 1,500 to 2,000 kilometres on Campagnolo EPS.
Practical advantages
Beyond the technical advantages, electric groups offer several practical benefits, including cleaner routing of electric cables compared to mechanical cables and sheaths. This criterion is even more important for electric bikes, which are often used in urban areas.This feature is even more appreciated on recent bicycle frames with internal cable routing.inside the frame tubes.
The mechanical group: a safe and reliable choice
Despiteall the advantages offered by electric units, their use remains limited to a small audience compared to their mechanical counterparts. The latter are considered more reliable, easier to maintain and, above all, less expensive.
More affordable
Although the performance of electric generators is highly appreciated, their price remains the main obstacle to the widespread use of these components. In fact, the price of a complete electric generator (including electrical parts and generator components) is around double that of the same mechanical model. When you consider that a complete mid-range electric generator can be more expensive thana professional-grade mechanical generator, it is understandable to hesitate between more user-friendly operation and more advanced performance. Furthermore, the installation and, above all, any repairs to an electrical generator can be complicated and|>|>
A few dozen grams less
Excess weight is a disadvantage for electric groups compared to their mechanical counterparts, although the additional values shownOn the scales, the difference is minimal. In the case of complete Shimano groupsets, the mechanical Dura Ace weighs 2,149 grams, compared to 2,219 grams for the Di2, which is 70 grams more.|>
A guarantee of reliability</h3>
While the electric group refers to a new technology that is still unfamiliar to the general public, the mechanical groups are designedbased on proven principles, regardless of the improvements made by manufacturers. Therefore, choosing a high-quality mechanical unit is often a choice for reliability. A mechanical breakdown of the unit maybe fixed with basic knowledge, whereas an electronic breakdown may require the intervention of a professional mechanic.|>
A wider range of configurations for road bikes
Until now, electric groupsets for road bikes available on the market have been designed exclusively for compact or classic double chainrings. This factor inevitably limits the configuration options for cyclists who still prefer to ride with triple chainrings on the road.
Less maintenance àl’entretien
L’Maintaining a bike equipped with an electronic groupset is a delicate operation. During cleaning, it is essential to protect the electrical and electronic components of the group, otherwise you risk causing malfunction or irreversible damage to thesystem. Caution should also be exercised when riding in rainy weather, although some groupsets, such as Campagnolo EPS, are waterproof. Mechanical groupsets, on the other hand, are less temperamental and retain their performance with regular cleaning followed by lubrication andMechanical groups, on the other hand, are less temperamental and maintain their performance with regular cleaning followed by lubrication and periodic checking of the cabling.|>

Electric and mechanical groups: which one to choose
While electric groups offer many advantages, their price remains a deterrent for many cyclists. This group is recommended for intermediate or advanced cyclists who want to get the most out of their bike. The advantages will be more noticeable on frequent rides, longer distances or during training sessions. The electric group also requires greater care and patience. Handling electronic and electrical components requires some knowledge or the assistance of a bicycle mechanic. For its part, the mechanical group remains the most reliable alternative when starting out in cycling or when riding your bike for occasional outings or leisure rides.|>
Cyclists looking for more performance can also opt for a high-end mechanical groupset rather thaninvesting in a mid-range electric group. Electric groups are a fairly recent technology that are still in their infancyin its infancy, but certainly promises more extensive features beyond braking and gear changes. However, its price, which is out of reach for the general public, makes it a somewhat elitist component intended for regular or high-level use. The mechanical group, on the other hand, offers all the features expectedexpected from a bicycle group and remains the reliable solution for beginners and experienced cyclists who are more focused on performance.
