RSP Carbon Layback Seatpost

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.
