The BBB SkyScraper BSP-20 seatpost is an essential reference for demanding cyclists seeking versatility, reliability, and universal compatibility. With its 400 mm length and zero setback (0°), this seatpost suits MTB as well as road bikes, e-bikes, and urban bikes. Available in 30 different diameters ranging from 25.0 mm to 34.9 mm, it adapts to virtually all frames on the market, making it one of the most universal solutions in the BBB Cycling catalog.

Technical highlights

• Cold-forged 6061 T6 aluminum: this forging technique gives the seatpost exceptional strength while maintaining a contained weight of 295 g (diameter 26.2 to 31.6 mm depending on measurements). Rigidity is optimal even when the seatpost is extended to the maximum.
• Micro-adjustable dual-bolt clamp system: allows precise and secure adjustment of saddle angle and position. Compatible with traditional rails (7x7 mm) as well as oval and carbon rails.
• Extra-long 400 mm length: ideal for tall cyclists, sloping geometry frames, or practices requiring significant saddle height (bikepacking, gravel, enduro).
• 0° setback (inline): perfect alignment between the seatpost axis and the clamp head, offering a neutral position and allowing optimization of weight distribution and comfort on long rides.
• Multi-use certifications: approved for E-bike (EN 15194), MTB (EN 14766/ISO 4210), Road (EN 14781/ISO 4210), and Touring (EN 14764/ISO 4210). Versatility that reassures and guarantees durability.

Available variants

The SkyScraper BSP-20 comes in 30 diameters to meet all frame standards. Each variant maintains the same technical characteristics (400 mm length, 0° setback, dual-bolt system, weight ~295 g) and differs only in diameter:

• Classic road diameters: 25.0 / 25.4 / 25.6 / 25.8 / 26.0 / 26.2 / 26.4 / 26.6 / 26.8 / 27.0 / 27.2 mm
• MTB and modern diameters: 28.6 / 28.8 / 29.0 / 29.2 / 29.4 / 29.6 / 29.8 / 30.0 / 30.2 / 30.4 / 30.6 / 30.8 / 30.9 / 31.0 / 31.2 / 31.4 / 31.6 / 31.8 / 32.0 mm

Each variant has a specific manufacturer reference and/or EAN code (details in technical specifications). Designed in the Netherlands (The Hague) by the brand BBB Cycling, founded in 1998 by two former professional cyclists, the SkyScraper embodies the pragmatic Dutch spirit: simplicity, robustness, and uncompromising performance.

Use and compatibility

Thanks to its minimum insertion length of 110 mm, the seatpost guarantees secure fixing in the seat tube. The dual-bolt clamp system facilitates installation and ensures perfect saddle retention, even on rough terrain. Compatible with all saddles on the market (round, oval, carbon rails), it stands out as the ideal solution to replace an original seatpost, adapt a bike to one's morphology, or prepare a custom build for bikepacking, gravel, or touring.
