The INCOLOR SR Speedster Intropy is a highly stiff aero road bike with competitive aerodynamics and build quality, but it has overstated tire clearance and a delicate paint finish.
Pros
- Very stiff front triangle and excellent aero performance, competitive with top-tier bikes
- Good build quality and attention to detail
- Custom paint options available at reasonable cost
- Rear end comfort is good; bike handles predictably
Cons
- Tire clearance overstated (claimed 38mm, but max 32-35mm realistic)
- Paint is delicate and chips easily; protective film recommended
- Integrated handlebar is heavy (~400g) and top part uncomfortable due to rise
- ISP on SSR model has very limited adjustability (only 20mm via spacers); no fine-tuning after cut
Key Facts
- Frame weight (size 54 painted): ~890g as measured; claimed 720g for unpainted SR+
- Tire clearance: official 38mm, but actual maximum 32-35mm depending on tire and rim width
- Bottom bracket: T47A (77mm width)
Reviews & Ratings

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.
AI Summary
Pros
- Lightweight frame at 920g with hardware
- Good paint finish and build quality

The INCOLOR SR "Speedster Intropy" SR/SR+ (also referred to as SS/SS+) is a high-end Chinese aero road bike praised for its stiff front triangle, stable downhill handling, and excellent build quality. It features a 28.6mm round steerer, T47A bottom bracket, and clearance for up to 38mm tires. The frame is relatively light (around 890g for size 54 painted), but the integrated handlebar is noted as heavy (around 400g for 130mm stem). The bike offers aero performance close to top-tier bikes like the S5 and SL8, with a comfortable rear end but a stiffer front. The integrated seatpost (ISP) on the SSR model is a polarizing feature due to limited adjustability; however, Incolor now offers seat clamp spacers with different offsets for additional fine-tuning. Paint quality is delicate and chips easily, so protective film is recommended. The stock thru axles on the SR+ have poor hex fit and are not compatible with Specialized axles. Incolor provides a 30% crash replacement discount. The bike is available through distributors like Ciclisti (EU) and PandaPodium (US), with custom paint options.
AI Summary
Pros
- Very stiff front triangle and handlebar, no flex when pedaling hard.
- Extremely stable at high speeds and downhill, feels faster than actual speed.
- High build quality and attention to detail, easy assembly for experienced mechanics.

Cons
- Integrated handlebar is heavy (around 400g for 130mm stem), and the top part is uncomfortable to hold due to 20mm rise.
- ISP (integrated seatpost) on SSR has very limited adjustability (only 20mm via spacers) and requires careful cutting; no fine-tuning after cut.
- Front end transmits more road buzz and big bumps to hands compared to some competitors (e.g., SEKA, SL8).
