Cool up, warm down? We aren't sure on the terminology either, but one thing is for sure, this Radio Raceline Seat and Post combo will get your sorted when you need a long seat post at the end of the race to help you drain the lactic acid out the legs. Available in 3 sizes, there's a 400mm long post on the junior 22.2mm combo, and a 600mm post on the two bigger sized options. The seat post is full CNC machined 6061-T6 alloy to ensure that it has the strength to run it way up, and with a padded seat, you'll be cruising in comfort as you savour the win.
