Pedals are not the place to save chunks of weight. Having tried Xpedo Ti/ti, Ritchey WCS and Look Quartz Carbon/Ti they all fell apart irrepairably within 6 months and all cost over £150 rrp.
The Quartz are light, but are easily the worst product I’ve tried in my entire life, they just don’t work well! The Carbon/Ti ones seized solid after 2 rides, then the body snapped when I was taking them apart.
It’s the same of Eggbeaters, they’re light, but they fall apart regularly, and even with servicing the lightest ones won’t last more than a year or so!
XTR are light enough, dependable and will last forever, any lighter is a mistake IMO.
Candy’s will require regular servicing and still won’t last long, if that doesn’t bother you, then they’re good pedals.
