• He mentions that the derailleurs are not the only determinant of shifting quality. The supplied chainring, chain and cassette on the Java test bikes are not the best so it's hard to make an apples to apples comparison with the established brands
• FD sucks. He says that it feels like 'last gen SRAM' (not sure if he's referring to RED eTap A1 11s or Force AXS D1 here) where shifting under load especially uphill is difficult
• RD is fine and shifts like 'last gen Shimano' (R8070?) but has chain slap issues (not enough tension?)
• Lever buttons feel like a mouse click and aren't nearly tactile enough. Very mushy like SRAM pre-Rival/Force AXS D2.
• Due to how the inner shift button is half embedded into the leading edge of the brake lever, riding over bumps and uneven surfaces results in frequent accidental shifts
• You can see Joe Whittingham from China Cycling at 2:55 so you can look forward to his first impressions video
• He shifts up and down the entire cassette range at 3:45 and 4:05
• He says that the braking feels improved from the mechanical RX hydraulic he tried before

Direct mount hanger is a option for the rd. I can't figure out where a power cable goes for either derailleur. How do you charge the battery(s) what kind of battery.

Does that mean this hanger will be used for both gravel & road with a fairly big cassette clearance?

Thanks.  I'd never seen that mentioned before.

-I ordered the wrong "T47 for DUB" bottom bracket. Apparently there are two version of this standard: Inboard and Outboard. I ordered outboard. Inboard means the bearings sit inside the frame/cup, while outboard means they sit...outside of the frame. Outboard is (I think) is for MTB/Gravel frames because the road Sram DUB spindle I have did not clear the frame. The outboard T47 I have is too wide for the crankset so I have order the inboard version.
