Joe's No-Flats Super Sealant£11.99

Seals well, but pricey

BikeRadar score4/5

Plenty of micro particles for really effective plugging of holes. It sealed holes up to 3mm well. Like the other latex sealants there was no noticeable wheel wobble. It's naturally biodegradable and is OK for cold weather use.

Initial similarities to Stan's aside, the formulation did seem different. There was more clogging when squirted through the valve unless really well shaken (sidewall method seems better for this sealant). No scoop is provided and applicator handy is an extra £2.49.
