I reckon the Prime Primavera Shorty Carbon Saddle is an instant classic. I found it comfortable straight out of the box thanks to its flowing shape and perfectly judged padding. For a full carbon saddle, it's well priced too.
I've been really impressed with the Primavera X-Light handlebar in terms of performance. I was skeptical of it's super-low weight since it costs less than half the price of equivalent weight carbon handlebars but it has yet to yield any short comings.
Prime's BlackEdition 50 Carbon Wheelset represents the brand's first push to compete with high-end performance wheels. They vastly outperform their price-tag, with stable rims, great braking, smooth hubs and easy tubeless setup.
