as much as i thank 2pure for all their help repairing my CB pedals over the years i've sold them all..
i've bent and snapped spindles, destroyed bearings and worn out "wings" in times that no one would believe. 2pure always fixed them with no complaints (although they like to claim a lack of maintenance for most failures i personally believe that the CB pedal needs excessive looking after when compared to other spd's on the market). i had a candy come off still attached to my foot not 3 months old, only to be told i didn't grease them (i didn't, they were new in the box and 3 months old.. who'd have thought you needed the grease a brand new pedal out the box! i would have expected them to come pre greased and needed topping up after 6 months)
granted there are lots of people who love them (i love the float and the fact my knees were ok after riding on them) and will claim to never look after them or have any issue. for me having owned 2 mallet M's and 2 candy CL's and basically swapping like for like as 2pure etc repaired the broken pair i got bored… of dealing with a good (sorry great) idea poorly executed. grease ports needed, better seals needed, better bearings needed (maybe less so if the seals were good) stronger axle needed (i'm 12st on and bent one and snapped another) i could live with the wing's cutting into my shoes (with sole savers to protect and help clip in) but not the rest.
shimano don't have enough float for me and hurts my knees. Gone back to flats.
