Does anyone know if the Tririg adapter for Trek Speed fits TT-023 cockpit?

Here is an adapter for mounting a standard carbon computer mount to the single mounting hole on the TT-023 bridge.
The computer mount must be 16 mm wide at the point where it attaches to the 3D-printed part.

Greetings Bernhard

Yours might twist, sooner or later. I designed the following fixation.

Thanks, I did take a look, but couldn't see anything on their website - https://xmcarbonspeed.cc/collections/triathlon

you can write an email to Peter from xmc.
They released the D78CU-33 first time in Feb, but maybe didn't updated the website yet?

What disc wheels are people using? I'm thinking of the Elite Wheels Bundle, due to price, but it looks like they are on backorder.

Does anyone have any recommendations on what they have used for their builds?

Happy with my xmcarbonspeed

I contacted Chris with the same problem and told me to use 10-12mm screws for the front of the stem. I cut the screws, as mine were 15mm long, but I would recommend buying new ones.
This worked for me, as it allowed the stem to clamp with better grip the bars.

Thanks. And the torque u were using was still 6Nm? Or did u increased it as a shorter screw is not applying a stronger clamping force or grip?
Any assembly paste in addition?

How to fix the stem? Fixed them with 6Nm torque already, but still, a good impulse on the bar, is tilting it slightly the bar slightly

seems ThinkRider released a new firmware targeting the issue of abnormal power a few of u spotted. Lets see...

When will you all understand that this accuracy will go outta window after one sprint?

Oh my God, stop coming here and defending shitty products. Are you getting paid for it or what? Let people write whatever they want - it's an open forum. And yet again you show up here defending your poor/cheap choices. What a guy...

I'm not sure what you wanted to achieve with your post under my comment. I've shared data from my ride, even my assessment as an age-grouper - I'm not pushing 1200 Watt, but I did with 400-500 Watts - not sure u checked the data prior commenting ;). At least on my end, I've not seen the drift. I'm wondering if the majority of rider do way harder. Let me try another set with higher W, but in real life, for me, I'm not battling at this level.

Nothing against the test of GPLama, nothing about that this product might have weaknesses at requested performance of ambitious or pro rider. There might be is a compromise, but at this price point I consider this as more than acceptable. The set of Speedplay I have came 600€ a few years ago and they are obviously worse ... and it didn't bothered me (so far ...because I never compared them until now).

...check the data around 35-44min. It's uphill with short, but (for me) high intensity phases of 400+W followed by pausing pedalling. I don't see a drift ... maybe it's to low push or self adjustment is correcting it or ...

I did another test, 1h open ride on MyWhoosh, recording ThinkRider pp5 (I have the set with 165mm Carbon crank), Speedplay Pedals and ZwiftTrainer with 3 different devices. At the beginning I saw that the fine adjustment from last time installation (110%) needed to be tuned (to 105%, u can do this with the ThinkRider app on the fly). SelfAdjustment for pp5 was ON. Overall avg power during the ride was 195W (Trainer) vs 194W (pp5) vs 197 (Speedplay). Of course, I'm not riding 400+Watts, and I've tried to stop pedalling at decent (as I do usually outside as well)...

Make your own reading at https://compare-the-watts.com with the 3 fit files attached.

The 60m power curve shows an offset of 0.4%, and a max diff of 2.4%...

At this price point and with my age grouper ambitions, it's acceptable.
Any different readings?

I would be interested if ThinkRider is able to fix the residual error with a software fix.

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.
