The Shimano RS30 is part of Shimano’s Road Sport series “integrating the best technology of the race-proven DURA-ACE wheels but at economical price points. These wheels are great for training rides and / or use at the local races.”
With super smooth hubs and superb lateral stiffness, Halo’s Aerotrack wheels are undeniably fine, bombproof wheels for daily road and/or winter service but weighing 993g and 1030g (front and rear respectively) you wouldn't put them on a lithe track or TT mount.
The four hundred pound mark is a competitive price point for wheels: If you're looking to upgrade it's the kind of money that'll buy you something decent, and the Solitudes are certainly that. They're a well-built, good quality racing wheel that'll suit if you're aiming for racing or TTs. For more general riding, the all round appeal isn't quite as wide as some similarly priced offerings.
