The July edition of Cycling Plus surveyed the market for pedals. The winner was the Time Xpresso 6.
They weigh 210gms but I see that they make Xpresso pedals as light as 155g a pair.
This is what the magazine had to say in their summary:-
Time Expresso 6 pedals offer more features with lower weight and great durability, and all at a price that wont make your eyes water. For the rider new to the world of clipless pedals they offer a huge range of lateral and rotational float – which helps you avoid any biomechanical issues – whilst their easily adjustable release tension will suit learners and more experienced cyclists alike. Improved cleat engagement and strength are a step up over previous Times, and the only downside is that their lack of mass means they dont always hang down perfectly. Apart from that the Xpresso 6 delivers a cutting edge performance in a featherlight package.
The description in the Review said:-
The Xpresso 6 is the lightest conventional pedal on test, largely due to the use of a carbon leaf spring instead of coiled steel. This remains in the open position until the cleat is engaged, when it snaps closed, providing a a +/- 5 degrees of smooth angular float, 2.5mm of lateral float, and great security. The cleats allow you two Q factor options (the distance between your pedals), are positive in use and stand up to a lot of abuse, which the stainless steel protected enlarged pedal platform shrugs off with ease. But their lack of weight and improved bearing seals do mean they have a habit of not hanging down to assist engagement.
