Riser block and VICTORY Smart Trainer
The Rear Axle height of the VICTORY Smart Trainer is 345mm. No riser block is required to ensure a reasonably level set for most bikes compatible with VICTORY.
However a slim and mobile riser block is recommended, such as the JetBlack Smart Riser Turn or the Riser Turnblock. These turn blocks allow a slight raising of handlebars which can reduce pressure on sit bones and allow more freedom of movement of the upper body, relieving pressure on shoulders when cycling indoors.
The JetBlack Smart Turn has the added benefit of being compatible with Zwift to allow virtual steering through Watopia!
A riser turn block can also limit wear and rub on your front tyre.
