From across the road, the Trek Domane+ SLR 7 looks like a regular carbon endurance bike. The motor hides at the cranks, the battery hides in the downtube, and the whole bike weighs 27.89 lb. It’s Trek’s top 800 Series carbon frame with a 60 Nm TQ motor and assist up to 28 mph. I haven’t ridden it. I’ll compare it with the two other Domane+ models on the site and the Velotric T1 ST I filmed. Everything here comes from Trek’s product page, checked on Oct 28, 2026 and linked at the bottom.
A road bike first
Trek built the Domane+ SLR around its lightest carbon, 800 Series OCLV, and calls it a road-specific design. Trek points to a narrow Q factor (the distance between the pedals), a road tune for the motor and mode buttons on the brake hoods. Its endurance geometry is meant for long days rather than racing.
Rear IsoSpeed, Trek’s flex joint at the seat tube, is there to take the sting out of rough roads. The bike rolls on 32mm Bontrager Kwaremont RSL tubeless-ready tires, and the frame clears up to 40mm without fenders or 35mm with them. That means it can take gravel tires too, and there are fender mounts.
Trek’s page calls the Domane+ SLR its lightest e-bike ever. The newer Domane+ SL Gen 5 now lists lower weights (24.26 to 26.7 lb), so that line looks out of date.
Motor and speed
The motor is TQ’s HPR60, a compact unit Trek describes as very quiet. It has 60 Nm of torque and 350W peak. Trek’s two spec lists disagree on its continuous rating: the summary says 300W, while the parts list says 250W.
The SLR 7 is a Class 3 bike, so it assists up to 28 mph, and there’s no throttle. Class 3 bikes are banned on some paths and trails, so check our e-bike laws hub and Class 2 vs Class 3 guide.
Battery and range
A 360Wh battery sits inside the downtube. Trek says it’s good for about 60 miles in Eco mode. An optional 160Wh Range Extender, sold separately, raises that to about 90 miles in Eco, according to Trek. A TQ 4A charger is included.
The display is an integrated TQ LED unit with Bluetooth and ANT+, and Trek’s Trek Central app adds range estimates, ride tracking, motor tuning and navigation.
Components
This is a high-end build. Shifting is wireless Shimano Ultegra Di2, 2x12, with a Praxis carbon crank (50/34T) and an 11 to 34 cassette. Shimano Ultegra hydraulic disc brakes run 160mm rotors. The wheels are Bontrager Aeolus Pro 37 carbon, tubeless ready, covered by Trek’s lifetime warranty for the original owner and its two-year Carbon Care program.
The seatpost is a KVF aero carbon post, the saddle is a Verse Short Pro with carbon rails, and the stem is Trek’s RCS Pro. Trek’s two spec lists name different bars: the summary says a Bontrager Aero Pro carbon bar, while the parts list says a Bontrager Pro IsoCore VR-SF (40 to 44cm by size). Pedals aren’t included.
Sizes, stock and weight
There are seven sizes, 50 to 62. Trek’s 27.89 lb figure is for size 56, with sealant and no tubes. The total weight limit is 275 lb, including the bike, which leaves about 247 lb for you and your gear. On Oct 28, 2026, both colors were build to order and listed as out of stock in every size.
How it compares
Against the Trek Domane+ SL Gen 5, which I haven’t ridden either: the SL 7 AXS is $9,499.99 with a TQ HPR40 (40 Nm), a 360Wh battery rated up to 70 miles, 35mm tires and built-in lights, at 25.29 lb. It’s about 2.6 lb lighter and $500 less than the SLR 7 on sale, with less torque. The SLR 7 has the stronger motor and Ultegra Di2.
Against the Trek Domane+ ALR: the same HPR60 and 360Wh battery on an aluminum frame, from $4,999.99 at about 31.7 lb. On paper, you pay about $5,000 more for the SLR 7 to save about 4 lb and get the carbon frame, carbon wheels, IsoSpeed and Ultegra Di2.
Against the Trek Checkpoint+ SL: Trek’s gravel model with the same motor and battery, wider 42mm tires and 1x gearing, from $5,599.99 at about 30.5 lb.
Against the Velotric T1 ST, which I filmed: a 36 lb Class 1 flat-bar bike now sold as the T1 ST Plus at $1,399. It’s a very different bike, but it shows how much of the SLR 7’s price goes to weight and road performance.

Pros and cons (from the specs and sources)
Pros: 27.89 lb with a 60 Nm motor and 28 mph assist; top 800 Series carbon frame with IsoSpeed; Ultegra Di2 2x12; carbon wheels with a lifetime warranty; about 60 mile Eco range, about 90 with the extender; clears 40mm tires; $1,000 off on Oct 28, 2026.
Cons: about $10,000 even on sale; out of stock in every size online on Oct 28, 2026; 275 lb total limit; no pedals or lights listed; Trek’s spec lists disagree on the motor’s continuous rating and the handlebar; the cheaper Domane+ SL Gen 5 is lighter.
Who it’s for
On paper, the Domane+ SLR 7 fits experienced road riders who want a premium carbon bike with real help on climbs and long days, and who want 60 Nm rather than the SL’s 40 Nm. Riders who care most about weight should look at the Domane+ SL Gen 5, and riders on a budget should look at the Domane+ ALR, which has the same motor for about half the price.
