Rated 5 out of 5 by Beautiful Headset This CK headset is a beast. It has the newer griplock split ring design so it will hold onto longer forks no problem and keep your steerer happy. The seal on the bearing cap was difficult to get over the steerer tube compared to my old headset (use lots of grease!), but otherwise installation was no problem. Nice and smooth from day one and looks good. Base can be replaced to accommodate tapered fork in the future, and bearing cap can be further replaced to accommodate a 1.5 straight fork, so there's a good degree of futureproofness for your money spent. 19 July 2012
