SD - Thank you for these consistent updates. One thing I haven't seen on here yet. My wife just got the IA10 and is super excited about it. When picking it up after her fitting at the LBS, they mechanic and fitter recommended keeping the battery junction box cover off of the bike. They said that the Torx t9 screw is easily stripped and will become a problem after multiple removal attempts for charging purposes. Without the cover on: 1. The front end doesn't look as clean. 2. The junction box cables rub a little with the brake cable 3. Worried about liquid and debris getting into the opening. When we put the cover back on, we could tell that one of the screws was already pretty stripped. Is this a known issue or is this something the LBS should deal with considering it's a brand new bike?
I'm a practical guy so I also recommended to consumers they leave the covers off their IA when we introduced that model with aero brake covers. I hadn't realized that vanity was more important than access to the brakes for adjustment between training and racing wheels and swapping alloy-compound and carbon compound pads.
If it bothers your wife to leave the Di2 junction A outside the frame for regular use and tuck it away for race day, then don't. As for the risk of stripping the bolts, that's why we changed from hex to torx. With a careful hand and very low torque requirement I'm about 2,000 out of 2,000 for removing and installing bolts without stripping them. Your results may vary.
the junction A 5 cables can be shrink wrapped for added protection once the aerobar extensions trimmed and position identified. This protects them from any wear.
Debris can also enter the opening in the frame at the cable wire slot entry on the storage box on the top tube. The frame is not sealed.
