Thinkrider PP5 power meter

[waltini]

Maybe but with Easton interface the crankset on aliexpress are very expensive.

If you scroll to the top of the page, I posted this one. I have purchased for my gravel frame from Taobao and it is getting delivered next week to Australia. ($83 AUD, so cheaper than Aliexpress)

Senicx XR3 (on Aliexpress)  - https://www.aliexpress.com/item/1005010582023538.html

Easton, which will fit this power meter.

Guys, i think its working

not proper test and indoors and i was blown from yesterday ride, but xcadey gen 2 demonstrated some problems even indoors. pp5 solid on sprints like my pes505 or fsa powerbox
Tomorrow will ride proper test and post here. My test on xcadey in its thread with setup and method if you want more now

I have 1 suspicious sprint undershoot (900 vs 950 and flat cadence reading from pp5), but everything else seems fine. Please check my files, maybe i missed something

Whole ride was with +3% offset for pp5 (after my first ride), but i think it should be +2% - 1 watt under direto on low watts and spot on on 300+ is better than exact low watts but +2-5 on high

Comparing with Elite Direto (very first one) and Magene PES505.
For past 7 years Direto was tested with FSA PowerBox (Power2Max NGEco) and Xcadey gen1 spider. In those tests Direto had identical readings with some constant offset - fsa no offset, magene offset +4%, xcadey gen1 -2% - so Direto my control device.
I have only spider PMs, so no triple recording and no outdoor comparison

Test protocol - copied from GPLama, with free ride first, sprints, some ERG work, more sprints and 2 stops in the middle for calibration. FIT files and screenshots attached

I really think they did it. Now we wait for Shane and others guys, especially outdoor rides, to be certain

Nice one - even the initial testing is very helpful.

More input attached (can be used with compare-the-watts.com). Was recording a MyWhoosh session (32min) with 3 devises in parallel, each recording another single power source - Zwift trainer, ThinkRider and Wahoo Speedplay. All calibrated before (as well the trainer after warmup). At ThinkRider I needed to change the sensitivity to 110% (max value, this is possible in the TR app) as I had a constant shift vs Trainer of 20W (did yesterday already a run).

Feel free to comment.

24rmm alu spindle...

[alfiomotrambo]

So cheap

[DavidG]

Only if the power data from PM is usable otherwise not that cheap for a piece of aluminium ;-)

[Rajmundx]

24mm alu spindle is not good?

[gandalf]

But is alu?? Crankset yes, but I haven't read anything about spindle... It seems like cruz ones that I  have in my sons bike and they spindle is not aluminium

24rmm alu spindle...

Are you sure about this? There is no mention of what the material of the spindle is. And given the weight, I would assume it’s steel.
