INCOLOR SR "Speedster Intropy": 3 Reviews, Specs & Prices

The INCOLOR Speedster SR/SR+ is a Chinese aero road frameset that delivers stiffness, high-speed stability and build quality competitive with premium Western bikes, with owners frequently rating it on par with an S-Works SL8. Measured weights run higher than the unpainted claims, the official 38 mm tyre clearance shrinks to about 32-33 mm with a front derailleur, and several small hardware niggles (integrated seatpost adjustment, titanium saddle clamp, thru-axle hex fit) recur across owner reports.

Pros

Very stiff front end and bottom bracket; pedaling stiffness measured at 181 N/mm (SR+)1 2
Aero performance competitive with top aero bikes: 3W less drag than a Tarmac SL8 at 45 km/h, frontal area 3.2% smaller than a Cervelo S5 and 1.7% smaller than a Tarmac SL8; aero bottle kit saves up to 8W and the integrated bar 2-3W2
Extremely stable at speed and on Alpine descents, confident enough to ride hands-off1
Proven over high mileage: 20,000 km on an SSR and 27,000 km on an SR+ without significant issues1
More comfortable than expected for a race bike, especially on 28-30 mm tyres; owners rate it on par with an SL81
High build quality and good paint finish with straightforward assembly and nice internal cable routing1 3
Custom paint at reasonable cost, a 30% crash replacement discount and saddle-clamp spacers for ISP fine-tuning1
The 600 ml aero bottles work well and the cages also hold round bottles1

Cons

Integrated bar is heavy (about 400 g for 130x355) and its 20 mm-rise tops are uncomfortable to hold1
SSR integrated seatpost allows only 20 mm of spacer adjustment once cut1
3D-printed titanium saddle clamp on the SR+ cracked or loosened on a few bikes and cannot be torqued to its rated 4 Nm; owners use 2.5-3 Nm or the aluminium clamp1
With a front derailleur, tyres wider than about 32-33 mm measured do not fit despite the 38 mm claim1 3
Paint chips easily on some frames and the fork crown collects dirt; other owners report no chips after 20,000 km1
SR+ stock thru axles have a poor hex fit and wear; Specialized axles do not fit1
Front end passes more road buzz to the hands than some rivals; rear brake hose routing through the fork is fiddly1
Higher price than typical Chinese frames, with limited availability and objective reviews in Western markets2

Key Facts

Claimed weight 720 g unpainted (size 54); measured about 890 g painted for a size 54 frame, 920 g with hardware for a 58 cm frame2 1 3
Official tyre clearance 38 mm, but with a front derailleur owners find about 32-33 mm measured is the practical limit1 3
T47A (77 mm) threaded bottom bracket1 2 3
28.6 mm round steerer; headset MR128 (40x52x7 45°) upper and MR137 (37x46.9x7 45°) lower1
Frame material M60+T800 (SR) or 80T+T1100 (SR+); wind tunnel tested at SSEH in Silverstone, UK2
Aerowav integrated bar weighs 340-416 g (about 400 g for 130x355); a lighter Aerowav version with new drops and textured tops was announced in November 20261
SSR integrated seatpost allows only 20 mm of spacer adjustment after cutting; Incolor sells -2/+2/+4 mm clamp spacers1
SR+ 3D-printed titanium saddle clamp is rated 4 Nm but owners run it at 2.5-3 Nm; the aluminium SR clamp is 7 g heavier (161 g vs 154 g) and takes full torque1
UDH hanger for Shimano and SRAM included; crash replacement offered at 30% discount1 3

This Isn’t Your Typical Chinese Carbon Bike | Incolor SR+ Build

The reviewer discusses the In-Color SR+ frameset, noting it is an aero race bike with a geometry similar to a Tarmac SL8/SL9. The frame is lightweight (920g with hardware) but heavier than the unpainted claim of 720g. The finish is good and cable routing is nice, but the tire clearance is overstated (claimed 38mm, but actual maximum is around 32-35mm). The bike feels stiff and is suitable for aggressive riding, though not ideal for very tall riders.

Intropy Speedster SS(+)

The INCOLOR Speedster Intropy SR/SR+ and the integrated-seatpost SSR (also called SS/SS+) are Chinese aero road frames praised for stiffness, high-speed stability and build quality. They have a 28.6 mm round steerer, T47A bottom bracket, UDH and an official 38 mm tyre clearance, but with a front derailleur about 32-33 mm measured is the practical limit. A painted size 54 frame weighs about 890 g, and the integrated Aerowav bar about 400 g; a lighter Aerowav version with new drops was announced in November 2026. Long-term owners are very satisfied: - one has 20,000 km on an SSR and 27,000 km on an SR+ without real flaws or paint chips; - a beginner on an SR found it comfortable on 28 mm tyres and very stable; - many owners call it on par with an SL8, disputing critical Cyclingnews and YouTube reviews. Recurring niggles: - the SSR's integrated seatpost leaves only 20 mm of spacer adjustment; - a heavy bar with uncomfortable tops; - paint that chips on some frames; - poor hex fit on SR+ thru axles; - a 3D-printed titanium SR+ saddle clamp that cracked on a few bikes and cannot take its rated 4 Nm. The aluminium SR clamp is only 7 g heavier and takes full torque.

AI Summary

Pros

Very stiff front end and bottom bracket; power transfer is a standout.
