With road disc standards beginning to settle down now Shimano have laid down some industry “standards” (12 thru front and 142 x12 rear) Chris King have released details of their R45D thru axle options for road and cyclo cross / gravel / adventure cyclists. The good news is that if you have a set of R45D with QR you can upgrade to thru axle with an axle swap. Here’s what CK have to say –
Road or CX disc with thru-axle? We’ve got you covered….with the introduction of a growing number of disc brake thru-axle cyclocross and road bikes, we have designed two new axles to allow our hubs mate up to your new frame. 142×12 R45D rear and 100×12 R45D front axles will convert your QR R45D hubs.
For those of you with a 15mm thru-axle fork we also offer our ISO in 24h drilling to mate with the many 24h disc rims on the market.
