A note about disc and other structural carbon fibre wheels: For all their expense, structural composite wheels (from any manufacturer) are sometimes not as accurately constructed (laterally true and round, properly dished) as what might be obtained in a well-crafted spoked wheel. While I will certainly reject any wheel that falls outside of the manufacturer's tolerances for these parameters, some margin of error cannot be consistently eliminated. If you find this unacceptable, you should acquire the wheel locally where you can observe and measure its accuracy prior to purchase.
