Despite it being new to the market,we’ve had three different examples of Manitou’s Jack post under testing for a couple of months now and, so far, it’s doing OK in normal conditions. The cable nipple hooks into the mechanism on the seatpost base for easy trimming at the lever end, but be careful not to strip the small cableclamp grub screw if you’re hamfisted. There’s currently only a vertical-action ‘universal’ remote available, but it’s reasonably light in leverage. Combined with the neat two-bolt head, it helps keep the post fairly light. The drop is smooth off the top, and return speed is prompt enough without being threatening.On really muddy, cold rides,we’ve had problems with ice sneaking past the seal and causing stickiness. While a clean and lube gets it going again quickly,we don’t know how this potential contamination will play out long-term. This is the only issue we’ve had, though, and it’s a reasonable price if it keeps on keeping on.
