TMARS 27.2mm DROPPER SEATPOST, REMOTE HEIGHT ADJUSTABLE 27.2mm SEATPOST.

Well, it's a bit rubbish. Tricky to use when riding and vdry easy to break. Only three adjustable heights. Looks awful. The only positive is the seller was very helpful when I damaged it. But I imagine he just wants to rid himself of the stock! Spend another 50 quid and get a proper post would be my advice.

Works well and very cheap compared to other dropper posts which are crazy money

You simply can’t go wrong for the money. I’ve had one for 7 years and I’m a 6’4”, 19stone stone rider. It’s never let me down. I’ve never even serviced it but there is admittedly a bit of play in the post. It’s not noticeable when riding though.
