General
A TQ e-bike system makes the Domane+ SLR look, sound, fit and feel like a road bike. The Domane+ SLR 6 comes with the TQ HPR50 motor, and the Domane+ SLR 7 and 9 come with the HPR60 motor.
Domane SLR+ uses Endurance Geometry. Compared to the H1.5 geometry found on Madone and Émonda, Endurance Geometry features a taller head tube and longer wheelbase to maximise comfort and stability.
Recommended tyre clearance standards for this model have changed. Accurate values can be found in specs on each bike model page.

Yes – all Domane+ SLR come with tubeless ready wheels, tyres, valves and TLR sealant.
The Domane+ SLR has hidden mudguard mounts to be used with SKU W331954 and the RCS Pro stem is Blendr-compatible.
No, electronic drivetrains only.
Remove the magnetically attached IsoSpeed assembly cover using your hands. Loosen the exposed M6 bolt, adjust the seat post to your desired height, torque the M6 bolt to 5.2Nm and reinstall IsoSpeed assembly cover.
That bolt is only removed when full IsoSpeed service is performed. IsoSpeed is not adjustable.
No.
The RCS Pro is an all-new, integrated stem that shares compatibility across several different road models. It keeps the cables tucked out of sight while also allowing riders to swap stem sizes without having to remove any brake hoses or shift housings. The RCS Pro is available in both -7 and +7 degree rise.
No.
No – the spot where a top tube bag would go is used by the TQ display. There are no hard mounts for bags on Domane+ SLR.
No.
We lengthened the chainstays to make room for the TQ motor housing.
TQ system
Most other e-bike motors use gears and belts to transmit power. These parts take up more space and can make noise or break. The TQ HPR50 and HPR60 use a harmonic drive transmission that’s small, simple and dependable.
Up to 300 watts of assist, 50 Nm of torque, 360 Wh battery
28 mph in the US and UK, 25 kph in EU & AU, 45 kph in NZ, other markets subject to local speed regulations.
The Trek app does everything the TQ app does, including motor tuning customisation, range estimations and general e-system information. In addition, the Trek app includes tyre pressure recommendations, service reminders, useful navigation and range features, activity tracking and more!

All bikes come with the TQ SmartBox installed. It has output ports for front light, rear light, aux 12 and electronic shifting.
Trek will stock TQ parts that are used on the Domane+ SLR, as well as the optional Range Extender battery, harness and wire.
Yes! The 'dead' battery will supply about 300 shifts to the rear derailleur, even though it no longer has the power to run the motor.
Yes, Trek distribution centres will stock TQ batteries. Due to hazmat shipping regulations, batteries cannot be returned.
1,835g
Yes. There is a charge level indicator on the battery with five bars and an optical switch. Cover the bar on the end, and the rest will light up according to the current charge level.
Approximately two hours.
No, it will just stop charging when it is full. However, never leave a charging battery unattended.
No, but you should charge it. The battery can be damaged by storing it completely empty. If you aren’t going to ride the bike for three months or more, keep the battery charged above 30%.
Please note that the battery will only last to about 15% capacity the first time it is depleted. So don’t be alarmed if the range on your first ride is a little shorter than expected. After the first full depletion and subsequent charging, the battery management system will 'learn' what it needs to know and will deplete all the way to 0% on future rides.
Also note that whenever the battery reaches less than 10% charge, the motor output will be reduced to 110 watts. The battery level indicator will flash to indicate Low Battery mode.
While the TQ power meter is accurate enough for the TQ system to provide smooth, natural assist, it is not accurate enough to provide athletic training data. For training purposes, we recommend a pedal-based power meter system.
Yes – the torque vs cadence curves are flattest between 60-90 rpm, and peak torque begins to fall off at around 95 rpm.
The TQ motor only needs firmware updates, which are completed by a Trek retailer.
Riding Domane+ SLR
Range varies significantly depending on many factors such as rider weight, assist level, tyre choice, riding surface, terrain and more. With that in mind, you can expect about 60 miles/97 km with the internal battery and about 90 miles/145 km with the optional Range Extender.
There are three assist modes.
There are mode-change buttons mounted to the shifters, so you don’t have to take your hands off the controls to shift modes.
Yes. Both the Trek Central and TQ apps allow you to adjust max power, assist factor and pedal response according to assist level. If you don’t like your changes, it’s easy to reset back to the factory settings.
Not for the Domane+ SLR.
Follow the temperature range guidelines in the Quick Start guide.
Range Extender
Through your local Trek retailer. Range Extender batteries (5289555) are not eligible for return by the retailer due to hazmat delivery regulations. Each retailer will set their own policy regarding customer returns of Range Extender batteries.
You’ll also need the power cable (5289576) and retention strap (5299107): this will now include four button-head cap fasteners (W575056), if not, contact customer care.
How much does the Range Extender weigh?
It is 160 Wh, which gets you approximately 40% additional range
Yes! This also allows you to fly with Domane+ SLR by leaving the main battery behind and taking the 160 Wh Range Extender in your carry-on. Check with your airline before travelling to confirm compliance with regulations.
This job is not for the faint of heart, but an experienced home mechanic can remove the battery in 15-30 minutes. Remove the drive unit cover, remove the drive unit, remove the screws that hold the battery charge port in place, remove the battery. To put it back together sans battery, re-install the charge port bolts, re-install the drive unit, then re-install the motor cover. Sound like too much work? Your local Trek retailer is happy to help.
Approximately one hour.
Yes!
We strongly recommend using the Bontrager Side Load cage (5324465) and the retention strap (5325177). Other cages may work, but we have not tested them. Always use the retention strap.
