[QUOTE] [QUOTE] Don't be stupid. Go and try taking the front wheel out of your bike without removing the calipers.[/QUOTE] Got me completely baffled there - I can't for the life of me imagine why you'd need to do so. It's been a while[1] since I've done it myself, but I've stood by and watched tyre changes dozens of times on modern twin-disk bikes and never seen anyone remove the calipers. [1] 20+ years, at least.[/QUOTE] Tyres are a bit wider now and they just wont clear. I struggled to get the calipers over the discs and clear of the wheel on Adies R1 because clearances were that tight.
