Specialized Command Post BlackLite Review

Components Pro Reviews

Bottom Line
The Specialized Command Post BlackLite that has been reliable, smooth and a very functional three position mechanical seatpost that is simple to use. Having the options of 75, 100 and 125mm of travel, opens up a whole slew of uses, from x-country to freeride. The mechanical system gave me no issues, and the collet and adjustable air spring internals have worked exceptionally well, with three solid locking positions, although the middle one can be indistinct to locate. The remote worked decently, and the inline adjuster was easy to use on the fly, but the lever throw was stiff and awkward to use. The ability to use the quick-release functionality made it handy to swap the seatpost between different bikes, albeit it does require a second remote. The saddle clamp needs to be cranked down tightly, else it can loosen, making for an interesting riding experience.

The Command Post has been a fine mechanical adjustable seatpost, that has done its job without issue, and I enjoyed how stichion free and quick the stroke was.

    Not sure how SP can claim this to be 100g lighter than previous model when they list 500/530/545g (75/100/125mm size) and the previous model MTBR review is 525.2g (100mm) ! I have last version and like it a lot, but it’s a lot heavier than gravity dropper (even though it uses air shock rather than a spring) or the jopplin (which I do not like as the head wiggle and I need to be fully up and locked as being off a bit will eventually hurt my knees

    Bought a BlackLite in April. Worked great until the first of Sept. when it started to leak air.Took over 6 weeks to get it back from the shop. Lots of excuses from the shop about Specialized as to why it took so long. Had only two rides on it and it just shot right out the top. Total failure. Now at the end of Oct., still no seat post back from Specialized. Not very happy about this Very Poor Service.
