Strong, well finished, excellent value

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

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

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.

Super looking seat post

This seat post has been installed onto a classic De Rosa frame which is being rebuilt it had to be silver to match the rest of the campagnolo parts and it looks great.

Beware expensive imitations

You can spend an awful lot more dough on a saddle which is no better than this.

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.
