Algupära
The Ultralight was BH's response to the weight-weenie road segment — a line that prioritised the scales above all else. The BB386EVO bottom bracket, oversized downtube, and monocoque HCIM carbon construction were all selected to shave grams while maintaining the lateral stiffness needed for sprint power transfer. Over time the line evolved into the Ultralight Evo, which pushed the frame closer to sub-850 g territory, before the Aerolight superseded it as BH's primary performance road platform.

- Jõuülekanne
- Shimano groupsets from 105 to Dura-Ace; 2×11 or 2×12 depending on build year
- Pidurid
- Hydraulic disc (current builds); rim brake on early pre-2020 builds
- Rattad
- 700c, tubeless-compatible on current builds
- Rehvid
- Road/all-road tires, 25–30 mm (build-dependent)
- Geomeetria
- Climbing-optimised race geometry: aggressive stack/reach for low frontal area; short wheelbase for responsive handling
- Kaal
- Ultralight RC: ~16.3 lbs (7.4 kg) complete; Ultralight Evo frame: sub-850 g target

Verdikt
+Tugevused
- HCIM construction achieves exceptional stiffness-to-weight in the climbing class
- BB386EVO bottom bracket makes the power transfer feel immediate and direct
- Long lineage refined through years of competition feedback in Spanish stage races
−Nõrkused
- BB386EVO requires press-fit installation — prone to creaking if not perfectly installed
- Older builds lacked tire clearance beyond 25 mm — limiting comfort on rough roads
- Superseded by the Aerolight as BH's headline road model
