Who said you can't buy free speed?  Molten Speed Wax has been measured by Friction Facts to reduce chain friction by up to 6w!  Thats not a small amount and adds up to minutes in an Ironman distance triathlon.  So go ahead, buy some speed.  

Send in your own (hopefully newer) chain and it will be fully ultra-sonically cleaned before being treated with Molten Speed Wax.  The chain is then sent back to you and ready for speed!  A final touch of Race Powder just before your event will shave a bit more friction of your chain.  (Powder included).  

The treatment lasts for about 600 km before needing to be reapplied or treated with normal chain lube.
