Lots of power, wrong timing: Magura Gustav Pro in a disc brake comparison

- Larger brake discs increase the braking force via a longer lever arm and improve thermal management and fading resistance thanks to a larger friction surface.  
- 140 mm and 160 mm are only suitable for light riders, short or flat terrain; they are undersized for touring, long descents and heavier weights.  
- 180 mm is the trail standard as a compromise, while 203 mm offers maximum braking power and heat stability for >85 kg, E-MTB and long descents.

Small, large or huge: Which brake disc do I need?

- Hope Tech 4 Evo GR4 offers high braking power with low hand force and an easily adjustable, rather soft pressure point
- High-quality CNC production, easily adjustable lever width and pressure point; criticism of DOT brake fluid and lever ergonomics for small hands
- Top values in dry braking, only midfield in the wet; loud noise under load can be annoying in continuous use

- Tunap Sports offers a PFAS- and fluorine-free surface protection spray with a hydrophobic layer for frames and components.  
- The spray is suitable for matt and glossy surfaces, protects against water, dirt and UV radiation and lasts for several washes.  
- Temperature-resistant formula, application after washing on dry surfaces, 300 ml can costs 13.95 euros and is available from specialist and online retailers.

Perfect frame protection: Tunap brings surface protection spray

- Regularly pull the seat post out of the seat tube, lubricate it and thus prevent seizure and possible total damage.  
- Check safety-relevant screw connections on the cockpit and seat clamp for correct tightening torque using a torque spanner.  
- Replace the handlebar tape and seal the paintwork after washing to improve the look, reduce dirt adhesion and make cleaning easier.

Safely into the cycling season: keep your bike looking like new with these tips

- Vor der ersten Tour Laufräder, Reifen, Bremsen, Antrieb, Schaltung und Fahrwerk systematisch auf Verschleiß, Funktion und Einstellungen prüfen.
- Bei E-Bikes Akku vollständig laden, Kontakte reinigen, ggf. Batterien von Remote/Schaltung tauschen und per App auf Firmware-Updates prüfen.
- Sicherheitsrelevante Teile wie Cockpit, Sattelstütze und Griffe mit Drehmoment anziehen, schmieren bzw. auf festen Sitz und ausreichenden Grip kontrollieren.

CARE | LUBRICANTS

- Correctly adjusted cleats prevent knee and foot problems and improve comfort, efficiency and long-term health.  
- The decisive factors are the longitudinal position under the ball of the foot, lateral alignment and rotation angle, ideally mirrored on both shoes.  
- The Ergon TP1 adjustment aid facilitates precise, reproducible adjustment; in the event of pain, a specialist retailer, bike fitter or orthopaedist should be consulted.

Ergon TP1 adjustment aid: pedal plate adjustment made easy

- Cheap cable and chain locks from Aldi and Lidl offer hardly any theft protection and can be picked quickly with bolt cutters.  
- The Crivit toolbox from Lidl contains many outdated, less durable tools and is only suitable for occasional emergencies.  
- The Aldi mini pump works, but the holder collides with your feet and the storage compartment is impractical to open.

Bicycle products from discounters: These parts stand out negatively

- Günstiger Montageständer (29,99 €) mit 30 kg Traglast, höhenverstellbar, 360°-Kralle, Teleskoparm und Werkzeugschale, aber wackeliger Klemmung.
- Vier Standbeine geben Halt, können auf unebenem Boden kippeln und geraten beim Schrauben mit den Füßen in Konflikt.
- Geeignet für Gelegenheitsschrauber mit nicht zu teuren Rädern; für schwere E-Bikes und empfindliche Carbonrahmen nur eingeschränkt empfehlenswert.

TOOLS

- Mechanical shifting systems with Bowden cables wear out and require maintenance; electronic systems are self-adjusting.
- The limit stops of the rear derailleur and front derailleur limit the swivelling range and must be checked after replacing parts at the latest.
- Remove resinified grease from older Shimano derailleurs with WD-40 and lubricate rear derailleur/front derailleur joints with oil.

Bike gears: The most important tips for the spring check

- FSA offers E-MTB cranks, chainrings and spiders with broad motor compatibility, variable crank lengths and material options for efficiency and safety.  
- MegaTooth chainrings, customisable chainlines and the "E-Bike Bible" facilitate precise drivetrain tuning and reliable function in tough terrain.  
- Special FSA carbon and aluminium wheels, including Gradient i30 and NS SC i30, increase stiffness, precision, durability and traction with a higher system weight.

FSA E-MTB upgrades: How cranks & wheels improve your ride

- A.GR.TI Kurbel: 3D-gedrucktes Titan, auf Jahrzehnte Haltbarkeit ausgelegt, Gravity-zertifiziert, lebenslange Garantie, ca. 20 % schwerer als Trail-Optionen.

Changing the bottom bracket on a mountain bike: How to replace the bottom bracket on your bike

- Pressure point on the brake lever early and defined, otherwise air in the system or pad wear; change DOT fluid every two years.
- Check brake pads, discs, callipers and rim flanks for minimum thickness, grooves, dirt and foreign bodies, clean or replace if necessary.
- Replace rim brake pads if grooves have disappeared, remove aluminium particles; keep Bowden cable running smoothly, correctly fitted and secured.

Bicycle brakes: the most important tips for the spring check

- Sintered pads are hard, low-wear, heat-resistant and constant on long, wet descents, but louder and less snappy in normal operation.
- Organic pads are softer, quieter, easier to modulate and offer high braking performance at normal temperatures, but wear out more quickly.
- Sintered pads are suitable for frequent and bad weather riders, while organic pads are the more versatile all-round solution for most riders.

Metallic or organic: which brake pad gets the most out of your disc brakes

- The Hayes Dominion A4 showed weak dry braking performance but very strong wet braking performance in the laboratory test with recommended metallic brake pads.  
- In practice, it offers sufficient power, very precise modulation and excellent lever ergonomics with suitable pads.  
- BIKE evaluates brakes according to the DIN standard on the test bench as well as in extensive practical tests with standardised test conditions.

BRAKES

- Carbon frames are made from cut, resin-impregnated prepreg layers that are placed in moulds by hand, cured and finished.  
- Price and performance depend heavily on manual labour, fibre quality, manufacturing expertise and production location (Asia vs. Europe/Germany).  
- Carbon offers a very good ratio of weight, stiffness and fatigue strength, is repairable, relatively material-efficient, but recycling remains a challenge.

FAQ carbon production: 20 questions about the miracle material carbon

- Stahlrahmen gelten als langlebig, komfortabel und haben einen emotionalen Wert, sind aber im Vergleich zu Aluminium und Carbon weniger verbreitet.
- Der Bau eines Stahlrahmens erfordert präzises Handwerk, wobei individuelle Anpassungen und die Wahl der Legierung entscheidend sind.
- Stahl ist gut recycelbar und reparierbar, jedoch anfällig für Rost, besonders in salzhaltigen Umgebungen, und benötigt daher spezielle Pflege.

Interview with a frame builder: What makes steel bicycle frames so special?

- In einem fünftägigen Kurs baut der Reporter mit Rahmenbauer Leo einen maßgefertigten 32-Zoll-Stahlrahmen, einen der ersten dieser Größe weltweit.  
- Der Rahmen entsteht in intensiver Handarbeit: präzises Schleifen, Biegen, Löten bei bis zu 1200 Grad und mehrfaches Neuansetzen bei Fehlern.  
- Der Kurs vermittelt tiefe Einblicke in traditionellen Stahlrahmenbau, schafft körperliche Grenzerfahrungen und eine starke emotionale Bindung zum fertigen Rahmen.

- Listening to music on a bicycle is permitted in Germany as long as ambient noises such as bells or sirens remain audible at all times.  
- Excessively loud music that impairs the perception of traffic can result in a fine and contributory negligence in the event of an accident.  
- Operating a smartphone while driving is prohibited; hands-free operation is permitted, but the following still applies: avoid distraction and, if in doubt, do without music.

Soundtrack on two wheels: Is listening to music allowed on the bike?

- The decisive factors for MTB marathons are suitable equipment, well thought-out self-sufficiency and balanced weight planning depending on the route and conditions.
- Sufficient food and liquids, a tyre repair kit, multi-tool with chain rivet, chain lock, weather protection, GPS, mobile phone and money are essential.
- Transport via hydration waistcoat, frame storage compartment, Velcro fastenings and jersey pockets; rucksack and saddlebags are considered disadvantageous due to handling and comfort.

- Low tyre pressure and wider tyres increase comfort, traction and often also speed on real, uneven roads.  
- The optimum pressure depends on the system weight, tyre width, rim, surface, tubeless, weight distribution and riding style.  
- Professionals today usually ride 28-32 mm (road bike) tyres with significantly less bar; gravel and MTB use even lower pressures for grip and control.

Optimum tyre pressure for road, gravel & mountain bikes: Deflate!

- Discounters such as Aldi, Lidl and Tchibo offer some surprisingly good bike accessories with a strong price-performance ratio.
- We recommend Crivit road and gravel helmets, battery-powered compressors and three light sets with solid workmanship and function.
- Sufficient for everyday use, commuting and as a second set-up, premium products remain the better choice for ambitious tours.

Aldi, Lidl and Tchibo bike products: Helmet, light sets and battery pump - recommendation

- SKS Germany bringt zum 60. Jubiläum des seit 1966 nahezu unveränderten Rennkompressors eine limitierte Sonderedition heraus.  
- Die Jubiläumspumpe setzt auf klar lackiertes Stahlrohr, Echtholzgriff, Messingdetails und eine nummerierte Messingplakette mit historischem SKS-Stern.  
- Technisch bleibt sie analog mit Manometer bis 16 bar, 271 cm³ Hubvolumen und drei Pumpenköpfen für nahezu alle gängigen Ventilstandards.

PUMPS

- Before riding, thoroughly check tyres, inner tubes, sealant, valves, bearing play, concentricity and spoke tension and remove any wear.
- Tubeless requires clean tyres, fresh, unmixed sealant and free valves; old sealant and residues must be completely removed.
- Tubeless offers less rolling resistance, more comfort and puncture protection, but is more complex; tube systems are simpler and more puncture-friendly.
