This is a new never build up Giant Team Columbia (High Road) 2008 prototype of the size XL. Only the SRM wire harness is assembled. The short stem is attached to hold the fork / headset bearings in place.
The geometry is to the Giant stock dimensions. I have seen on the smaller sizes (S and M) that the top tube was around 15 mm longer than stock. The stock frames had a designated size call out SS and MS means Small Standard (Stock) and Medium Standard Stock dimensions.
But on all frames of 2008 is the drive side BB configuration of the 86.5mm by 41mm standard change in the way that only the generic standard BB ball bearing 37x25x6 [mm] can be pressed in. The ball bearing was machined (two longitudinal cuts 180 deg apart with the hacksaw to release the press fit by reducing hoop stress) out of the Standard DA outboard cups. In the picture above you can see the Ball bearing pressed in and standard plastic bushing.
With this change the clearance get bigger between the SRM power cranks and the BB housing, and the O.D. of the bearing has firm contact alignment to the machine metal housing, instead to be embedded into a plastic housing with 2mm wall thickness.
On the non-drive side you see the standard configuration of the 86.5 by 41 standard and the aluminum insert of the drive side with significant higher wall thickness.
The wire harness for the SRM system which enter into the frame in front of the BB, in the
hole foreseen for the outlet of the shifter cable, exits the frame near the front brake cable stop.
If the SRM cable is now routed parallel to the brake cable in a heat shrinkable hose it
looks like a wireless system.
An update will follow how it looks with the SRM Power cranks, the speed and power sensor in place.
