How to fit a tight eMTB tyre without damaging the bead or rim
To fit a tight eMTB tyre, create slack before applying more force. Reinforced casings can be awkward to handle, but the final section of bead becomes easier when the rest sits in the rim’s deepest centre channel. A bigger lever cannot make up for a bead trapped on the wider seating shelf. This guide covers…
How to clean and dry a hydration reservoir after a muddy ride
A hydration reservoir needs more than a rinse of the bag. Water and drink mix also pass through the hose and bite valve, and moisture can remain there long after the outside looks dry.

Can you mix tubeless sealants? A practical MTB and eMTB guide
Do not mix different tubeless sealants unless the maker explicitly approves that combination. Two white liquids labelled “latex” can contain different particles and additives, and a tyre holding air after a top-up does not prove the mixture will seal the next puncture. For MTB and eMTB riders, the straightforward approach is to top up with…
Why does a new MTB chain skip on an old cassette?
A new MTB chain that skips on an old cassette often points to worn sprockets, but it is not proof that the cassette is the only problem. The wrong chain, incorrect installation or a setup issue can produce a similar complaint. Work through those checks before ordering a replacement cassette. This guide is for diagnosing…
How to clean an eMTB chain when backpedalling does not move it
If your eMTB’s cranks turn backwards but the chain stays still, the usual chain-cleaning routine will not work. On many mid-drive systems this is normal: the cranks can freewheel backwards independently of the chainring. You need to move the chain forwards by hand, with the rear wheel safely off the ground, or clean it a…
