premium product for budget price
by Anonymous user on 09/09/2020

Superb finish and good seat clamp, no movement. I bought this to put on my city roadster bike but ended up putting it on my seventies classic colnago road bike which has a campag' sr group set, it is that good!

System EX seat post
by Anonymous user on 16/06/2020

Good length, a little heavy and the clamp is a bit basic, but great value for money. Fine for a casual cyclist, but more serious bikers will probably look elsewhwere

Strong, well finished, excellent value
by Anonymous user on 28/08/2018

I was pleasantly surprised to see the quality of this when it arrived. An engineering friend of mine would not believe that it was such a good price. The whole finish and construction is superb. Highly recommend.

Great seat post
by Caleb G on 25/02/2016

I wanted to replace my seat post which was really rusted out bad. This is one of the least expensive seat posts you're gonna find. it's long, it's adjustable when mounting the saddle, and the black has a real nice finish. I couldn't ask for more.

Long and sturdy at good price
by John R on 10/11/2015

I was looking for an extra long seat post - I'm tall and my bike is only a medium - and this was about the longest I could find anywhere. It seems sturdy and fitted easily. Can't complain about the price eiether.

Seatposts Guide

What are seatposts?

The seatpost is the extendable metal rod that slots into your bike’s frame, with a clamp at the top to hold your saddle.

Who needs a seatpost?

Every bike has a seatpost, but a common reason for fitting a new one is to get a longer post for a leggy rider. Weight saving is another prime reason for upgrading.

What are the choices?

You need to pick the right seatpost width for your frame, but then you will have a choice of materials, from practical aluminium to weight-saving carbon. Mountain bikers can also opt for dropper posts, which are tremendously useful out on the trails.

What should I buy with them?

You might need a different seatpost clamp to go with your new seatpost and hold it firm in your frame.

Anything else?

Finding out which seatpost width you need can be a tricky business. With luck it will be stamped on the inside of your bike’s seat tube. It is measured down to tenths of millimetres, so eyeballing it with the tape measure won’t work.
