Ultra Heavy Duty Tube 80/100x21 inch straight valve.

Michelin Ultra Heavy Duty tubes are 4mm thick. These are a great option for dirt riders who need to run low tyre pressure and for all adventure bikes. These tube weight just under 2kg so we dont recommend them for MX riding. Use this tube in 80/100-21, 90/90-21, 90/100-21 tyres.
