Re: Thinkrider PP5 power meter I've tested another PP5 as someone sent me an unopened PP5. Notes: - Firmware v1.8.6 installed. - PP5 was charged ~80% but needed to be fully charged again after installing the update. - Installed with every bolt/etc to spec. - PP5 meter was tested with Assioma PRO RS-2 (indoor and outdoor) and NEO 3M smart trainer (indoor). - After one of my first peak power sprints the PP5 read low (this occured with the first PP5 and C10 I've tested) - Following sprints (not all of them) caused the PP5 to over-read (same as with the first PP5 I tested). Residual torque issue remains. - PP5 power data was inconsistent across three tests (2hrs outdoors. 1.5hrs total from two indoor sessions). - When stopping to manually zero the PP5, it'd then line-up with the other baselines. Doing this three or more times per ride, after any hard effort isn't great. ThinkRider initially responded (to someone else asking about my testing) with: "Our tech team has tested it, and the issue isn't that serious. It's probably an installation problem on his end." It wasn't an installation issue. And I've now proven (with data!) issues with this hardware exist on TWO PP5 units, and these issue persist after installing their latest firmware update (as of April 24th 2026). The latest communication I've had from ThinkRider is that they HAVE replicated this issue and will work to resolve it in "next products". My testing and results have been validated by the manufacturer. The unit has issues. This isn't ideal for anyone who owns a PP5, but it's one step towards them having an excellent power meter on the market at an excellent price point. I'll loop back here again when I have more information. I'll try meet with them in Shanghai at China Cycle in a few weeks. April 23, 2026, 08:15:05 PM	1
Re: Lightcarbon: LCR018-D (endurance all-road) Hey fellow V1 Door owners, I might have something for you. A small 5cent 3D printable part which safes you latch, door, bottle cage with bottle during the ride. Put way to much time into it and still not perfect, but 90% is good enough for something like this https://www.printables.com/model/1753559-safety-tab-thingy-for-downtube-cover-v1-lcr018-d It's adding 2mm between the door and bottle cage, and you just have to bend the tap upwards and than you can use the latch. Will take a little test ride now Edit: Works and did not open during the ride June 14, 2026, 06:20:26 AM	1
