Buying advice

- High-end e-bikes and carbon-fibre bikes are driving up the cost of damage; traditional combination locks are considered inadequate against organised thieves.
- New locks rely on fingerprint sensors, app control and biometric technology to make keys and combination codes obsolete.
- High-security models use graphene, ceramic armour or pepper spray chambers to make attacks with angle grinders more difficult and deter thieves.

Bicycle locks: Using fingerprint recognition and a stink attack to deter thieves

- The author finds road cycling shoes impractical and expensive, despite comfortable models such as the Specialized S-Works Torch, particularly when walking.  
- Problems include the risk of slipping on tiles and cobblestones, noise in stairwells and a lack of confidence when walking; The risk of falling is illustrated by examples.  
- She prefers gravel shoes with SPD pedals: they offer more sole area and grip, are quieter when walking, and are more suitable for everyday use, as performance and split times are less important to her.

- Oko markets its own brand, Magic Milk, and offers several sealants for tubeless and clincher tyres.  
- According to the manufacturer, Tubeless-Pro Hi-Fibre seals cuts of up to 8 mm, whilst the more affordable Original seals cuts of up to 6 mm; both have a shelf life of around 6 months.  
- Innertube Sealant for inner tubes is available in Hi-Fibre, Original (Tubolito-approved) and organic versions, all of which are ammonia-free and come in a well-designed bottle.

- Lightweight summer base layers improve moisture-wicking and evaporative cooling, and prevent your jersey from becoming soaking wet in the heat.  
- The key factors are an open mesh structure, low weight, high breathability and a close-fitting cut, rather than the brand.  
- The article cites the Assos Summer NS Skin Layer P1, Craft Pro Dry Nanoweight and Castelli Core Mesh 3 Sleeveless as the best options for the height of summer.

- Thin summer base layers improve moisture management in hot weather, increase the surface area available for evaporation and can thus help to keep you cool.  
- Particularly useful on long, intense rides, in the mountains, when wearing tight aero jerseys or when sweating heavily; sometimes unnecessary for short, leisurely rides.  
- Suitable materials include lightweight polyester/polypropylene and mesh fabrics for temperatures above 25 °C, as well as merino or blended fabrics for varying levels of exertion and multi-day tours.

- The 100% A2 follows the trend towards slimmer, frameless shield-style sunglasses with a subtle look and a wide field of vision, ideal for sport and everyday wear.  
- A lightweight Grilamid TR90 frame, Ultra Grip Rubber, adjustable temples with a copper core and three nose pads are designed to ensure a good fit, secure hold and comfort.  
- Ultra HD polycarbonate lens with 3D construction, hydrophobic/oleophobic coating, UV protection and optional HiPER contrast lens; price €149.90.

- Shimano Shadow+ levers on GRX and Cues rear derailleurs activate a damping mechanism that reduces chain slap and keeps the chain more securely on the sprockets.
- When riding, the lever should be set to ‘On’; when fitting or removing the rear wheel, set it to ‘Off’, as this allows the derailleur cage to move more freely.
- The lever does not increase chain tension, but merely dampens the movement of the derailleur cage; the new generation of GRX uses Shadow ES without a lever, which provides greater damping.

- From August 2026, Maxxis will be launching Maxx Seal, its own synthetic latex sealant, for its range of tubeless tyres.  
- The ammonia-free liquid is designed to be gentle on materials, seal punctures of up to 7 mm and function reliably from -20 °C to +55 °C.  
- Maxx Seal is compatible with CO₂ and inserts, and is available in recycled PET bottles (250 ml, 500 ml, 1 l) as well as in 5-litre canisters.

- Chain oil lubricates reliably and is easy to reapply, but it attracts dirt and requires more frequent cleaning of the drivetrain components.  
- Chain wax keeps the chain clean, reduces wear and runs efficiently, but requires thorough degreasing and, in some cases, more frequent re-waxing.  
- Wax is particularly suitable for dry gravel conditions, whilst oil is better for rain, long rides and changeable weather; regular maintenance is key.

Components

- Quad Lock comes out on top in the test, but at 25–90 euros it is the most expensive option in the range, as it requires a mount and a model-specific protective case.
- The bayonet lock secures the smartphone firmly to the stem, either vertically or horizontally; it requires some force to turn, but feels very sturdy.
- The slim, robust case provides protection for everyday use whilst maintaining ease of use; accessories include adaptors for aero handlebars, the stem and a rain cover.

Stays rock-solid: The Quad Lock Out Front Mount + Mag Case is the test winner

- Fidlock Vacuum combines magnetic force and vacuum technology, offering ease of use and high smartphone compatibility via an adhesive pad or case.  
- Weighing 50–51 g, the mount is very light, has a compact design and leaves all control buttons accessible, though it wobbles slightly on rough sections.  
- It can be fitted using clamps for various handlebar diameters or cable ties on aero handlebars; the editorial team awarded it a ‘recommended buy’ rating.

- The Infini Glaux and Aegle Pro form a connected lighting system that can be controlled simultaneously and with minimal distraction via a handlebar remote.
- The Glaux front light offers up to 1,200 lumens, a brightness sensor, multiple modes, USB-C fast charging, IPX6 protection and costs €67.99.
- The Aegle Pro rear light delivers up to 65 lumens, a wide beam angle, auto-standby, energy-saving mode, IPX6 protection and costs €24.99.

Electronics

- Edge 850 offers precise data collection with multi-frequency GPS, up to 12 hours of battery life and customisable data fields.  
- Varia RearVue 820 STVZO detects vehicles up to 175 metres away, displays position and speed difference on compatible Edge devices.  
- In the Garmin bike ecosystem, radar and riding data are synchronised in real time and analysed in detail in Garmin Connect.

- UCI limits bike computers to 126 x 71 mm from 1 January 2028, justified with lower cognitive load and more safety in the race.  
- From 1 July 2026, front pockets on jerseys will be banned, except for radios; UCI cites aerodynamics, safety and equal opportunities.  
- Also from 1 July 2026, stricter, more uniform sanctions will apply for non-compliant equipment in several UCI disciplines.

UCI banned list: Jersey bags and large cycling computers are banned

- Battery-powered mini-pumps are more convenient and quicker than hand pumps, but more expensive and bulkier than CO₂ cartridges, and have their limitations when it comes to tubeless tyres.  
- The test winner is the large, heavy Silca: by far the most powerful, with the best battery life and minimal heat build-up, but a poor pack size.  
- NG Sports is the weakest performer; Muc-Off is powerful but has ergonomic shortcomings; Dynamic gets very hot; Trek is slow; Topeak is well-balanced with good ease of use.

- Lightweight, water-repellent rucksack (approx. 17 l instead of 20 l) made from stretchy material; however, the outer compartment is not waterproof.
- Simple organisation: storage space with little structure, well-padded laptop compartment, few internal pockets.
- Comfort and ventilation are average; the back system and build quality are disappointing; not recommended for frequent commuters at this price.

- Modern bikepacking racks offer better weight distribution, greater stability and more loading options than large saddle bags.  
- Three main mounting types dominate the market: thru-axle for maximum stability, threaded eyelets for continuous use, and seatstay mounting for bikes without eyelets.  
- The Tailfin Journey Rack is considered the most versatile rack, the Restrap the workhorse, the Aeroe for full-suspension bikes without mounting points, and the Ortlieb Quick-Rack L for everyday use.

- Zentrales Element ist ein Smart-Trainer; empfohlen wird der Wahoo Kickr Core 2 mit Zwift Cog und Click als preiswerter Einstiegs-Trainer.
- Ergänzt wird das Setup durch vorhandenes oder altes Rad, Ventilator, Bodenmatte, Handtuch sowie Bildschirm und eine Trainings-App.
- Ein funktionales Indoor-Cycling-Setup ist für unter 700 Euro möglich, hinzu kommen optionale Abo-Kosten für Zwift oder Rouvy.

- Fully integrated cockpits offer minimal aerodynamic benefits on road bikes, but result in complex maintenance and high workshop costs.  
- When replacing the headset, stem or handlebars, cables often have to be disconnected, rerouted and the brake systems bled (200–400 euros).  
- For gravel and mountain bikes, there is no functional benefit; aerodynamic advantages are irrelevant, and semi-integration is considered a more maintenance-friendly compromise.

Cockpit: A service nightmare – full integration is going to be expensive!

- Weight optimisation on a bike makes little difference in everyday use; what matters most are aerodynamics, rolling resistance, drivetrain maintenance and tyre grip, depending on the discipline.  
- On a road bike, air resistance is the dominant factor: clothing and riding position save significantly more watts than a bike that is 1 kg lighter, even on an Alpine pass.  
- For gravel and MTB riding, lower tyre pressure reduces rolling resistance, whilst on an MTB, a clean, waxed drivetrain can also prevent losses of up to 30 watts.

The weight myth: Why we ignore the real energy guzzlers

- Gravel handlebars strike a balance between control and comfort; key factors include width, flare, drop, backsweep, aero shape and adaptation to the rider’s body geometry.  
- Aluminium with moderate flare, a flat drop and a slight backsweep is usually the best compromise; carbon offers more damping but comes at a higher price.  
- Stem length, spacer height and the option of fully integrated handlebar assemblies influence riding position, handling, aerodynamics, maintenance requirements and costs.
