That is what worries me (- referring to Tron's comment -). The Superstar Mag Lite pedals weigh 340g (275g with the ti axle) and it does concern me that they may be too light.
I currently have some Tioga Surefoot Pro pedals that weigh about 460g and have stood up to everything, including being clouted on rocks in the Whistler bike park. So basically I'd have to spend a fair bit of money to make a weight saving worth having: Is it worth it?
I'm using the SuperStar ultra mags. (Non-ti version)
No problems yet with the pedal body or the bearings. Only issue is that the paint has come off when I've clipped them on rocks. They've not cracked or dented though, nor have any pins gone walkies. I got them September 2009.
