FS SRAM 172.5 compact cranks

For sale, black SRAM S500 cranks, 172.5mm compact. Less than 600 miles use (they came on a bike, I use 165mm cranks but thought I would try them for a month), anodising still almost perfect, will send pictures if you are interested. NO outer ring, bottom bracket or chainring bolts but includes a 34 ring with no more than 30 miles use. Offers around £25 plus p&p at cost.
