Incolor Speedster SR vs SR+: what does ¥6,000 buy?
The SR+ cost ¥6,000 more than the SR in the official-store listings retained on 29 August 2026. Its claimed bare frame is 65 g lighter under the same stated conditions. Geometry and published tire limits are shared. This source-based comparison helps decide whether the different lay-up and hardware package matter to your build; it is not a ride test.
The differences that the records establish
The official product document and exact-model SR listing and SR+ listing underlie this table. All prices and package details are snapshots dated 29 August 2026, not current checkout quotes.
| Decision point | Speedster SR | Speedster SR+ |
|---|---|---|
| Official-store listed frameset | ¥12,800 | ¥18,800 |
| Claimed frame weight | 785 g | 720 g |
| Weight basis | Size 54, unpainted; paint and metal hardware excluded | Same size and exclusions |
| Claimed lay-up | M60 + T800 carbon | 80T pitch-based + T1100 carbon |
| Additional included part | Standard package | 3D-printed titanium component package |
| Published geometry and tire envelope | Shared platform; 1× up to 38C slick or 36C small-knob, 2× up to 32C slick | Same published limits |
The premium does not buy extra clearance or a new fit
Both variants use the same six-size Speedster platform, UDH, asymmetric T47A and integrated AEROWAV cockpit. The manufacturer product page provides the geometry, but the table still needs to be checked for your intended size and position. The larger 1× tire limit cannot be transferred to a 2× build with a front derailleur.
The maker reports bottom-bracket stiffness values of 175 N/mm for SR and 181 N/mm for SR+. No independent protocol is published, so these numbers are not evidence of a perceptible ride difference. Neither variant has enough independent long-term evidence here to claim better durability or quality control.
Which one makes sense for your build?
Choose SR as the value reference if the shared geometry, tire room and included cockpit solve your requirements. The retained ¥6,000 gap can instead fund other parts, but this comparison has no current component quote and makes no claim about how much performance those parts would add.
Consider SR+ when the specific lay-up, stated 65 g bare-frame reduction and extra titanium parts justify the premium to you. The 65 g is a difference between manufacturer claims on unpainted size-54 frames, not a measured complete-bike saving. Compare exact package contents and final checkout prices before ordering.
- Confirm your exact frame size, cockpit dimensions and package contents.
- Match the tire limit to a 1× or 2× drivetrain and your actual tire.
- Request a current, variant-specific total for the frame, missing parts, assembly and delivery.
Source trail and what remains unknown
The SR model record and SR+ model record retain exact sources, price conditions and manufacturer claims. The official listings were observed on 29 August 2026; neither checkout was submitted. Stock, discounts, dispatch and shipping can change.
This is desk research with AI-assisted editing and translation. We did not ride or weigh either frameset. No independent stiffness protocol or controlled durability comparison was available in the retained evidence.
