Extremely low profile ideal for slammed stems
A .2mm lip and concaved underside - one of the lightest and lowest profile top caps available. If you are having trouble seating your standard top cap to a shortened steerer tube this will do the trick. Instead of shaving off another 3mm of carbon steerer or running a tower of spacers, simply replace your top cap with one of these and you'll only add 6.5g (including bolt)
32mm wide outside diameter will seat flush with most quality spacers for a slick finish.
