How can you convert to disc brakes when it doesnt have rear disc brake bosses????Have considered both these bikes but probably gonna opt for a Cervelo S3 which has all the aero advantages of the Canyon and BMC but is a little more compliant at the rear end for my 55 year old ar*e! Also comes with the option to convert to disc brakes in the future, which is probably the way all road bikes are heading.
About the same price with electronic shifting, although the Mavic wheels are not as good.

Both will be great bikes however the brake at the BB would put me off the BMC. Also judging from the photo it doesnt have an internal battery...thats a bit daft for an aero frame.
Downside of the Canyon is that the aeroad had big delays in delivery earlier in the year, im not sure what its like now though.
