My initial review of the Lightweight Obermayer wheelset is now published.
The Obermayers take the prize for the best wheelset I’ve yet ridden— light and very fast and very comfortable. If you can afford the Obermayers, place an order now.
The only real downside: gusty side winds; like all aero rims they can be pushed around from the large surface area sailing in the wind. Ripping along at 40 mp down a moderate hill, a strong side gust is not an experience I care to repeat. But that is life with wheels having a big cross-section for the wind to catch. Consider a Ventoux 240 front wheel and and Obermayer rear for such conditions.
