If you have £1099.98 to spare then SRAM fail to offer anything special with these S40’s, they feel somewhat on the sluggish side, climbing and sprinting felt laboured whereas handling did not feel altogether controlled or comfortable, with rim depth at 39mm they are not the deepest or even lightest of Aero wheels, the S40’s just seem to be left wanting.  It does seem unusual for SRAM, they are not terrifically disappointing wheels but for the price you can do better.
