Tuning

- Shorter 155 mm cranks improve stance, control, centre of gravity and braking traction, especially downhill on E-MTBs and gravity bikes.  
- The more compact position facilitates low heels, more stable handling in high-speed and shock moments as well as controlled pedalling in technical terrain.  
- The disadvantage is less leverage when pedalling, which can be partially compensated for by a smaller chainring (32 to 28 teeth in the test), for example.

155 mm vs. 170 mm: Short cranks in the test - what they bring to mountain biking

- Zéfal Z Cage Adapter moves bottle cage on the bike by up to 40 mm and makes better use of narrow frame space.

- Supplied with screws (2× M5×10, 2× M5×16), RRP 9.95 euros, suitable for everyday use, touring and bikepacking.

TUNING

- 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?

- 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.

Checklist for the start of the bike season: tyres and wheels on MTB, road & gravel bikes

- 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.

Frame building craftsmanship: build a 32" frame yourself in the course

- Bike Ahead entwickelt in Veitshöchheim einen handgefertigten 32-Zoll-Carbon-Laufradsatz Biturbo X 32 Safe Wing als neuen MTB-Standard.  
- Die Produktion erfolgt in aufwendiger Manufakturarbeit: individueller Zuschnitt der Prepregs, Monocoque-Bauweise, Autoklav-Zyklus und sorgfältige Nachbearbeitung.  
- Pro Jahr können nur rund 100 Biturbo-Laufräder gefertigt werden; alle Daten jedes Laufrads werden dokumentiert, der vorgestellte Satz ist das erste 32-Zoll-Modell.
