This Gram Light 57DR is the most affordable wheel made by Rays Engineering. When making this design, Rays optimized the design and construct while still ensuring proper strength and rigidity. 

The 57DR is a cast wheel, so it will be heavier than forged and other Flow Formed Wheels, however the wheel is meant to withstand the abuse of the track and is just as strong as its forged counterparts. 

If you are looking for a quality performance wheel that won't break the bank, then look no further than the 57DR!
