Are there any pros/cons to going over centre lock rotors?
For the consumer, in my opinion, no benefits either with centerlock rotor or centelock hubs.
I’ve only got a centerlock hub on one set of wheels because I needed a quick cheap set and being DT factory wheels of the shelf they’re centerlock only (shops can get oem versions that are 6 bolt). Got perfectly good one piece 6 bolt rotors so I use an adapter. Cheaper than centerlock rotors.
The DT adapter is a bit rubbish though. It keeps loosening and it’s difficult to tighten down enough to grip the disc without play. It won’t come off and fine under braking but it’s weird when rocking bike back and forth with brake on. Can’t tighten on the trail unless I carry a bulky tool with me.
I’m thinking of swapping to Shimano adapter as they appear to bolt the disc onto the adapter, then you screw the adapter onto the hub.
All my other wheels are DT350 hubs that I specced with 6 bolt to avoid this nonsense.
