What Is The Length Of The Seatpost Above The Collar To The Saddle Rail?

By Sandy

18 Nov 2016

I'd really like to know the minimum amount of the seatpost that needs to be sticking out of the frame.

I'd like to know the weight of the seatpost too.

SJS Customer Service:

Hi,

You need at least 160mm of seatpost above the frame for this seatpost to fit. The seatpost weighs around 680grams.

Thanks.

Is This Actually Suspension Or Do You Just Move The Seat?

is this actually suspension or can you just move up and down the seat?

SJS Customer Service:

Hi,

This was originally designed to just be able to adjust the height of the seat, it was not designed as a suspension seat post.

Thanks.

Adjustable Seat Height Or Amortized?

By Anonymous

hi, this your seatpost is adjustable height range 10 cm? and when 'all extended the seat does not move? because on some sites I read vertical oscillation 15 mm, and finally it's mechanical (spring) or idraulic? are interested in his purchase, expect information, regard, Raffaele

SJS Customer Service:

Hi,

This seatpost does indeed have 10cm of adjustment. When extended it is not fully fixed and there is a small amount of movement similar to a suspension seatpost like that mentioned on other sites. This seatpost uses a sprung design to achieve its adjustment.

Thanks.
