Which Clipless pedals?

stay away from eggbeaters, the design is clever and the tension is good at first but then after not very long they slacken off and you can't get them tight enough again. obviously if you unclip accidentally while riding fixed it's not going to be a pleasant experience. the bearings on them are also shit: they seem to come out of the box with play built into them, and as far as i'm aware you can't just pop them open and service them like you can with spds.

I hear this a lot, and disagree. I have two pairs of candys, a pair of quattros, and a pair of mallts. I used to have a pair of eggbeaters. But I used them to extinction over many years (without any issues).

I would'nt ride fixed on eggbeaters. But after 4 years riding fixed on quattros I've never once uncliped accidently.

I use candys both off-road, and commuting through nordic winters. I've never had problems with them.

IMHO candys would make great pedals for those only wanting the same pedal on several bikes. They look ugly on road bikes though.
