Nukeproof's original coil-sprung OKLO post suffered from a range of problems when we tested it in 2015, including the saddle clamp coming loose on the shaft and the external actuator seizing up.
For 2016 though, the brand's engineers have completely reworked the post, and reliability is much improved.
We’ve been riding this new version for months with no sign of the head loosening. Meanwhile. the internally routed cable (there’s an external version too) keeps things contamination free.
The captured-barrel-clamp cable attachment is awkward to get right when fitting the post, because the cable has to be measured carefully and cut off flush for clean operation. Tensioning the lever correctly is crucial too.
In use, the post is painfully slow. It takes ages to extend or compress, which stops it clattering into your nether regions but is irritating if you’re trying to maintain flow.
Unscrewing the seal head, degreasing it and adding 10wt hydraulic fluid speeds things up slightly but it’s a shame there’s no easy way of altering the air spring pressure. At 830g (with lever) it’s extremely heavy too, and it only comes in a 31.6mm diameter so it won’t fit all frames.
