Steep head tube, short rear end, light as possible with strength where it matters are all the things that made the CK the frame of choice street riding. The CKv3 Frame builds on all those features and takes it to the next level with a 127mm head tube for increased strength and reduced stack height, investment-cast dropouts with inside knurling, built in chain tensioners and gussets on both the top tube and down tube. The CKv3 frame checks all the boxes, even the ones you didn’t know about.
