I've had a number of rear racks of my own design produced to fit the Ten, see the pic below.
            
 
             The rack is CNC machined from 4mm 5251 grade aluminium, anodised silver. 
            
 The 4 standoff posts are turned from 1050 grade ally. 
            
 Bolts nuts & washers are zinc plated steel.
             
            
 I had 10 made, of which five are still available, price is �43, plus postage. Depending on demand future batches will be larger.
             
            
 more pics will follow when i've had a chance to take them in daylight.
             
            
 please PM me if you are interested.
