Why does a shock pump hiss when you disconnect it?
A short hiss as you unscrew a correctly working shock pump is normally air leaving the pump hose, rather than your fork or rear shock emptying itself. RockShox and FOX both describe this behaviour in their setup guidance. The confusion often comes when you reconnect the pump and see a lower reading. Two different moments,…
DJI Osmo 360 II vs GoPro MAX2: what matters for MTB and eMTB riders?
DJI Osmo 360 II vs GoPro MAX2: we compare the features that matter for MTB and eMTB filming, from woodland footage and mounting to editing your ride.
MTB brake fluid explained: mineral oil, DOT and Shimano low-viscosity oil
How to choose the correct MTB brake fluid, avoid mixing mineral oil and DOT, and check Shimano standard versus low-viscosity oil before servicing.
Removable vs fixed eMTB batteries: what to check before buying
Integrated does not always mean fixed. Check charging access, pack removal, lifting and replacement support before choosing your next eMTB.
MTB freehubs explained: Shimano HG, Micro Spline and SRAM XD compatibility
MTB freehub compatibility becomes important the moment you replace a rear wheel or cassette. Shimano HG, Micro Spline and SRAM XD describe different fittings between those two parts. They are not interchangeable, and knowing that your bike has 12 gears is not enough to choose the right one. The quickest route is to find the…
Waterproof MTB clothing ratings explained: 10K, 20K and breathability
A 20,000mm waterproof rating tells you something useful about a fabric, but it cannot tell you whether a jacket will keep you comfortable on a muddy climb. Waterproofness, breathability and ventilation describe different things. Understanding the difference makes it easier to choose MTB clothing without paying for an impressive number that solves the wrong problem.…
Why MTB tyre pressure gauges give different readings — and which number to trust
Your floor pump says 25psi, but a handheld gauge says 23psi. That does not automatically mean the tyre has a puncture or that the digital display is correct. The gauges may have different measurement errors, the connection may have released air, or you may be comparing readings taken under different conditions. buy why do tyre…
Why your tubeless MTB tyre loses air overnight
A tubeless MTB tyre losing air overnight needs a little diagnosis before another dose of sealant or a new valve. The leak may be in the casing, bead seal, valve or rim tape, and the place where air escapes is not always where the problem started. Finding that route is usually more useful than replacing…
How to remove and fit MTB pedals without damaging your cranks
Learning how to remove and fit MTB pedals starts with one easily missed detail: the two sides do not use the same thread. Getting that right protects the crank, whether you are changing worn flats, fitting clipless pedals or packing an eMTB for a trip. Choose the replacement system before reaching for a spanner. Our…
How to check MTB brake rotor wear
Check MTB brake rotor wear by measuring the braking track against the minimum thickness for that exact model. Brake noise alone cannot tell you whether the rotor is worn out. Find the correct rotor wear limit Read the rotor’s minimum-thickness marking and confirm the model’s instructions. There is no single limit to apply to every…
