Bar tape cushions the grip and helps prevent hands from slipping. Replacing it also reveals the handlebar beneath: tidy-looking tape does not guarantee sound metal underneath. Signs of corrosion or cracks need assessment before the bar is covered again.
Remove lumps of old adhesive and secure any cable housing beneath the tape with thin adhesive tape. An even surface prevents old bumps from carrying through into the new wrap.
Padded tape is normally wound from the bar ends towards the centre. Keep the overlap consistent and the tension appropriate to the material. Check bends and lever clamps for gaps; unwind and rework an uneven section before continuing.
Trim the end with scissors away from the bar surface, taking particular care with carbon components. Secure the wrap with finishing tape and check that both bar-end plugs are firmly fitted. Brake levers must retain completely unobstructed movement.
Cleaning also depends on the material. Where the manufacturer permits it, wipe the tape with a slightly damp cloth and neutral detergent, then dry gently. Avoid solvents and abrasive cloths; follow the specific care instructions for specialist materials.
