The Crank Brothers Cobalt 11 carbon seatpost is available with with 20mm setback or zero setback. The setback post has a more relaxed seat angle for those looking to sit further behind the pedals. Superlight carbon fiber dampens vibrations, while the greater setback corrects steep frame angles and sets you up for more power when climbing.
The Crank Brothers Cobalt 11 carbon seatpost with zero setback has a zero setback for a more aggressive riding position and the ultimate in light weight. Superlight carbon fiber dampens vibrations, while the zero setback ensures it's easy to get behind the saddle on those descents.
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.
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.
