Cycling and Bikepacking Planning
Bikepacking combines cycling with lightweight camping, and getting your setup right is essential for comfortable riding. Weight distribution, tyre pressure and gear ratios all affect handling and performance, especially when carrying camping gear on multi-day rides.
Tyre pressure depends on rider weight (including bike and luggage), tyre width and terrain. Lower pressures give better grip and comfort on rough surfaces, while higher pressures reduce rolling resistance on tarmac. Our tyre pressure calculator accounts for all these factors.
Gear ratios determine how easy or hard it is to pedal at different speeds. For bikepacking with loaded panniers on hilly UK terrain, low gearing is essential. Our gear ratio calculator shows development (metres per pedal revolution) and speed at any cadence for your specific chainring and cassette combination.
