FSA SL-K seatpost £75

A great performing post

BikeRadar score 4.5/5

FSA uprated their SL-K carbon fibre components a couple of years ago and the result is one of the best budget carbon seatposts available. The SL-K is relatively light, cheap, easy to adjust and totally reliable.

In the two years that we've been running it, across several bikes, we haven’t had any issues. Most importantly for us, it's comfortable. Not all carbon seatposts can claim a tick in each of those boxes and even fewer alloy ones can. To get them all, at what's a knockout price for the spec, is awesome value.

FSA run one of the most stringent test programs in the bike industry to ensure that their carbon is up to the mark. Our own extensive ‘in-field’ testing of SL-K and its big brother K-Force back this up, and we simply don’t have any reliability issues to report; really, it’s that good.

The SL-K can be had with inline or 25mm set back heads so you can tailor it to maximise your bike fit. Flies in the ointment are few, though we would like more corrosion resistant hardware to stop the post from going rusty.
