BH Bikes has expanded its racing range with the new SL1, a model that bridges the gap between pure competition bikes and comfortable endurance machines. With a frame of Toray T400 carbon, optimised via Hollow Core Internal Molding (HCIM)-technology, the SL1 promises a balanced mix of lightness, efficiency and comfort. Just what riders are looking for for long distances without losing speed. We take you through all the details of the new BH SL1 endurance bicycle
High-performance carbon, focused on balance
At the heart of the SL1 is a Performance Carbon Layup made of Toray T400 - a material that is also used in BH's higher segments. Thanks to the HCIM technology, in which the frame is formed internally under high pressure, the carbon is more compact and consistent than in conventional manufacturing. The result is a light, rigid and durable construction, with controlled wall thicknesses in zones where forces are greatest.
The Compact Stay rear triangle, formed in one piece, contributes to direct power transmission and improved lateral stiffness. Combined with the BB386EVO step-down system and the oversized down tube, this ensures solid pedal response. Although the SL1 falls within the endurance segment, it is not inferior to the brand's competition bikes in terms of efficiency.
Endurance geometry with a hint of racing
BH positions the SL1 as a granfondo bike with racing genes. The geometry is designed to provide comfort and stability on long rides, with a slightly higher stack and shorter reach. Yet handling remains sharp and responsive, making the bike suitable for riders who like to pace without sacrificing comfort.
The full-carbon fork is optimised for both aerodynamics and vibration damping. It accommodates tyres up to 32 mm, and in some configurations even 35 mm, making the SL1 more versatile on rougher asphalt or light gravel. The fork also blends harmoniously with the frame, with a clean, modern look that matches BH's top models such as the Ultralight EVO and Aerolight.
Smart integration and refined finishing
In terms of integration too, BH shows that the SL1 is more than an entry-level model. Internal cable routing provides a clean look and less drag. The integrated saddle clamp is elegantly concealed in the frame and offers sturdy, low-maintenance clamping.
Practical detail: the hidden 12 mm Thru Axle Quick Lever system makes changing wheels easy without tools, while the design remains sleek and minimalist. The addition of a UDH derailleur hanger makes the frame future-proof and compatible with the latest generation of shifting groups.
Three versions, one frame
The SL1 series shares the same carbon frame, but is offered in three configurations that cater to different rider profiles and budgets:
| Model | Group set | Wheels | Tyres | Price |
|---|---|---|---|---|
| SL1 4.5 | Shimano Ultegra Di2 12-speed | Vision Team TC30 Disc | Hutchinson Nitro 28 mm | €3.999,90 |
| SL1 4.0 | Shimano 105 Di2 12-speed | Vision Team 35 | Hutchinson Nitro 28 mm | €3.299,90 |
| SL1 3.5 | Shimano 105 12-speed mechanical | Shimano RS171 | Chaoyang Shark 28 mm | €2.499,90 |
All models come with carbon front fork, internal routing system and thru-axle hubs.
A modern endurance bike with race ambitions
The BH SL1 endurance bike positions itself as a modern endurance bike that adopts the best features of BH's racing platforms - but with more comfort and versatility. The geometry is relaxed enough for long days, the frame light enough for mountain work, and the integration sleek enough for the modern rider who wants to combine performance and aesthetics.
In short: the SL1 is not a compromise, but a balanced choice for those seeking both speed and comfort. A granfondo machine with racing DNA - Built to devour miles without feeling heavy.
