Chinese BikesSource-based editorial review; no hands-on testing.
The SR+ is the premium Speedster: the same unusually broad 1× tire envelope and six-size aero platform, paired with the lighter 720 g claim, higher-grade lay-up and titanium hardware at CNY 18,800.
Best for: lightweight aero road and rough-road versatility, premium frameset buyer prioritizing the top Speedster lay-up
Buying checks
Incolor rates 2× builds for 32C slick tires
One 58 cm SR+ with Dura-Ace Di2 2× had little room at about 32.5 mm measured tire width; larger tires and 1× were not tested
A painted 58 cm SR+ frame weighed 920 g with hardware in one workshop's build video
The 720 g claim excludes paint and metal hardware
The 181 N/mm bottom-bracket stiffness figure is a manufacturer result without a published independent protocol
The CNY 6,000 premium over SR buys claimed weight, lay-up and hardware differences rather than a different geometry or clearance envelope
Independent long-term ride, quality-control and crash-replacement evidence remains limited

Fit and frame evidence
Tire clearance
Up to 38 mm with 1× / 32 mm with 2×.
Evidence: official source.
Slick-tire limits; 1× small-knob limit: 36C.
Front-derailleur, rim and tire choice affect fit.
Field check (Crafted Cycles video, 15:52): The fitted tires measured about 32.5 mm and left little room. The mechanics doubted 38 mm and expected 35 mm to be tight; neither was test-fitted. A 1× setup and the SR were not tested. Build: 58 cm SR+; Shimano Dura-Ace Di2 2×; GP5000 tires on wide rims.
Up to 38C slick or 36C small-knob tire clearance with 1×. 720 g unpainted size-54 frame claim. UDH and asymmetric T47A. AEROWAV integrated cockpit, aero seatpost and 3D-printed titanium parts included. Six-size official geometry.

The builders praised the finish, tidy routing, stiff bar and light weight, but found the bar heavy, the supplied bottles impractical and the tire room far short of the 38 mm headline on their 2× build.
ConfigurationCustomer's 58 cm SR+ built with 2× Dura-Ace Di2 at a UK workshop.
The dealer rates the routing through the compression ring, the 3D-printed titanium parts and the overall finish among the best he has seen; he had not built or ridden the frame.

Takeaways
Measured1:36The painted 58 cm SR+ frame weighed 920 g with its hardware. Incolor quotes 720 g unpainted without hardware; the builders found the gap plausible for a large painted frame.
Build note4:35The Di2 battery sits in a carrier inside the frame above the bottom bracket, so the very thin seatpost can be removed without unplugging it. Hose and wire routing through the frame was rated about 6/10 for difficulty.
Build note9:08Incolor's Aero Win one-piece bar (140 mm stem here, lengths to 150 mm) has very low stack and a negative stem angle with a cable spacer underneath. The hosts called it heavy at about 400 g but stiff, and its routing about 7/10 for difficulty.
Fit check15:52On this 2× build the fitted GP5000 tires measured about 32.5 mm with little room left. The mechanics doubted 38 mm tires would fit and expected even 35 mm to be tight on a wide rim. Incolor rates 38 mm for 1× builds only and 32 mm for 2×; no larger tire was test-fitted.
Build note18:06The supplied Incolor aero bottles sit low on the frame by design; the hosts found them rattly, hard to grab and awkward to refill, though aerodynamic.
Finish and faults23:41The very light seatpost uses a 3D-printed titanium clamp head; the builders questioned how robust its thin sections are over potholes but did not test it.
Ride impression27:02Verdict from the bench: good finish, tidy routing and a stiff bar, but buyers must accept the curved offset steerer and an aggressive geometry that may not suit very tall riders.

Takeaways
Repeats a maker claim0:21Incolor's engineer says SR and SR+ are the same model and mould with different lay-ups (T800 versus T1100), about 60 g apart, with the same comfort and build quality; the SR+ adds 3D-printed titanium parts.
Repeats a maker claim2:51He says the SR's CFD work took two to three months, the SSR's about six months, and a full new frame about a year from design to production.
Repeats a maker claim4:03The Voyager gravel/all-road frame, he says, shares the SR's design language with 45 mm tire clearance and takes a front derailleur; a longer, wider-clearance gravel model may follow.

Takeaways
Repeats a maker claim0:01The dealer says Incolor renamed SS/SS+ to SR/SR+ and that this size-54 frame is an SR+ still marked SS+; he reports the change followed customer remarks about the 'SS' name. Incolor's own sources do not state whether the frames are identical.
Build note1:25The Di2 battery sits in a holder under the bottom bracket reachable without removing the bottom bracket; UDH and direct-mount hangers are both supplied.
Build note1:53Brake hoses pass through dedicated holes in the compression ring so they never touch the round steerer, which is offset rather than straight to make room for them.
Finish and faults3:10Computer mount, expander cap, front-derailleur tab and saddle clamp are 3D-printed titanium; the dealer rates the finish among the best he has seen. A printed white paper of Incolor's test data comes in Chinese only.
Price at publication6:59The dealer's frameset price was €3,290 in October 2025 with these parts included; Incolor claims 720 g for the SR+ frame.
