In our never-ending quest to extract more performance from every car, we are pleased to announce Smokem's new RS top deck for the Xpress XQ11.

Drawing from our experience with previous RS designs, we set out to optimise the flex characteristics of the XQ11 to yield superior lap speed over a wider range of conditions.

A major benefit of the RS design is to allow the XQ11 to accept a large range of pinion gears. This is particular useful for 21.5T or higher blinky classes where big pinions are a must.
