ENVE 3.4 SES G2 Clincher Wheelset with Ceramic Bearings (Shimano)
ENVE describe this as a "climbing wheel with an aero advantage, designed to be ridden in the mountains" - we'd go a bit further than that and say it's one of the best all-round wheelsets for putting on the miles in a wide range of terrain.
If you do a fair bit of climbing, these are the ones to go for - light, strong and surprisingly aerodynamic. If you're more interested in speed on the flat, the ENVE 4.5 are probably the better choice of "do everything" wheel - a little deeper, a little heavier but also a bit more aero.
This set comes fitted with ceramic bearings, for the ultimate in low friction and long life.
