Another new TQ motor: hpr40

[Rás Cnoic]

So after many months of haunting the Canyon website the Endurace Onfly suddenly became available in my size today. Sadly it’s the Stealth black when I would have preferred the White but this is still not available and has been pushed back to November. Quickly convincing myself that I can love a black bike too, I pushed the order button and am now waiting for delivery in July. Unfortunately I am out of the country until August so will have to wait a bit longer for my first ride but am pretty stoked to finally get this on order after first seeing Yako’s review back in October last year.

Which model/version/tier? Tell me you splurged on the Sub 10! Need a photo of you holding it up with just your little finger!

Sadly (luckily) the sub10 isn’t made in my size 2XS. I’ve ordered the CF8 as the 105 version is not showing any availability - not even a long delivery date at the moment. Happy to have the ultegra group set but may sell the wheels as I already have a set of super light Hunts and I would hope that selling a brand new set of DT Swiss will go some way towards bringing my outlay back towards the cost of the CF7.

Just looked again at the Canyon website and the CF8 is now shows delivery October-November. Glad I pushed the button quickly, looks like they don’t have too many frames in that size.

This is the nature of DTC. Try buying a M2S Amflow. One minute they are in stock, the next they are not.

I'd like to add a handlebar-mounted assist control remote to my 2023 BMC Road machine AMP X (TQ HPR50 system and V01 display). At first I was not switching assist levels much, but now that I have set assist levels way down (30W,60W,100W) I find myself switching levels more to adjust to grade/speed/headwind)

It appears the current options are:

• TQ Remote V02 (listed for flat bars)
• TQ Remote V03 (listed for drop bars)
• TREK Domane buttons (2) with special splitter cable ?

Does anyone know the actual difference between the V02 and V03 remotes? Is it only the clamp diameter/mounting hardware, or are there other differences?

For those using the V03 on a drop-bar bike:

• Is it intended to mount near the stem/top of the bar, or can it be mounted on the side/underside of the bar behind the hood so it can be operated with your thumb while keeping your hands on the hoods?

 

[stompandgo]

I have a V02 remote and a V04 color display. Works fine. I change assist levels enough to not want to take my hands off of the bars.

As for mounting the V03 on drop bars, they would have to be conventional round bars. not aero top bars. The remote itself is fairly bulky, it needs a strong press to select, and it's wired. It's a bit big next to one side of the hoods. I would not like it, but it's cheap enough to try.

Purchased the VO3 control (31.8mm clamp) and mounted it below the left shifter on my BMC Amp. its out of the way, and allows me to change assist level while keeping my hands on the hoods. Not as nice as Di2 buttons built into each shifter but serves the purpose. Note that the cable that you have to route from the display thru the frame and integrated headset has a large connector which was difficult to route, too big to fish thru without a lot of disassembly.

I had the same issues, so I ran the remote wire first.

looks pretty clean!! i imagine it’s tricky work routing that through the headset. well done.

 

[apctjb]

Yes, one would hope that with the move to integrated bars and stems with internal routing that TQ would use a smaller molded connector. The one they are using appears bigger than is required for the job...

it seems like a lot of low voltage connectors are way bigger than needed these days! compare to the little tiny ones shimano uses for di2…

Significantly, however it has three conductors.

I have the same bike and I used the trek/TQ buttons. No problem routing the cables through the headset. I don’t know why they would have used a bulkier connector on your button. Either way, it’s a big improvement to get the buttons by the hoods and off the top tube!

 

[apctjb]

The buttons look great! They were out of stock on the Trek site or I would have gotten those instead. Looking at the button photo it appears they use a much smaller connector on the buttons...

 

[stompandgo]

Because the buttons require a splitter cable which has the TQ green connector on the other end.
less conductors = smaller connector. For the HPR40, I believe they plug directly into the bar end display, no splitter.

The TQ motor tuning settings can be somewhat confusing especially the relationship between max power setting, assist level setting and rider input required to achieve the max power setting. There are lots of ways to think about it, but the following is most understandable for me.

Excellent! Wish I had a reliable table like that for my power-sensing Specialized Vado SL 1.

This table gives saturation rider power (Prs) as a function of assist mode settings. Prs is the rider power needed to saturate (hit the motor power ceiling) in a given assist mode.

Handy to have a sense of how Prs varies with assist mode. Once you're pedaling at or above Prs, the only way to get more assist is to change assist mode accordingly. Conversely, pedaling harder gets more assist only when you're below Prs.

The following table might be of interest for those considering which TQ Motor best fits their riding style. Its easy to focus on maximum motor watts/torque but forget that there is a min rider input to achieve those values. For example if 150W is all your old legs are able to deliver then there is no benefit to going to TQ60 (because the max assist is 2X=300W) and the TQ40 is not going to cut it if you need >300W to keep up with your buds.
