This Pair of MTB Wheelchair Wheels are designed to be swapped for standard 24 inch wheelchair wheels for when the surface you\'re travelling on becomes bumpier, you want to safely go quicker or indeed you want that extra comfort. With their offset hub, these mountain bike style wheels are designed to fit your wheelchair without the need to adjust you brakes. If you want to use your wheelchair offroad, or introduce a powered wheelchair add on such as a TriRide, Klaxon or Batec, these wheels offer you the perfect solution. These mountain bike wheelchair wheels come fitted with black anodised pushrims. The Pair of MTB Wheels are fitted with Schwalbe Landcruiser tyres which incorporate Schwalbe\'s K Guard technology, a natural rubber that is reinforced with Kevlar fibres to give you that added peace of mind. These are a 22 inch rim with a 2 inch tyre depth to deliver a 24 inch wheel. The offroad wheels are designed to be used in conjunction with your existing quick release pins. However, if you are at all uncertain about compatibility please get in touch with us. The hub is a depth of 53mm, if your wheel hub is the same as per most standard Quickie and Kuschall wheels for example then you should be fine.
