The increase in reach on the new bike is due to the one piece cockpit, which will be 110mm regardless of which size I go with (I would prob do 100mm, but they're not available, so I either wait indefinitely or go with the 110mm). The one piece bar also has 10mm more reach than the Zipps I have on the Tarmac, so I've taken that into account.
