BH updated their Ultralight road bike, once again making it more aerodynamic, even as they shave grams away. Now 11% lighter than its predecessor, at less than 700g for the frame. Plus, it also gets a 12% aero drag reduction, care of subtly refined Kamm tails & other tube shaping. The fact that its also quite a bit cheaper from the entry 105 level to the top-tier, UCI-illegal weight Dura-Ace level is simply icing on the cake. (Photos/BH)No more need to pick a lightweight climbers bike or an aerodynamic sprinters bike. Just get one Ultralight.2027 BH Ultralight and aerodynamic carbon road bikeThe new MY27 BH Ultralight looks pretty similar to the version they launched back in 2023 to upgrade the aerodynamic performance of their lightweight road bike. But this new one is both lighter and more aero, developed in CFD together with the University of the Basque Country (EHU). And its still as stiff as before, creating a solid all-rounder for fast riding whether heading to the mountains, sticking to the flats, or all the rolling terrain in between.What else is new?Dropping the frame under 700g makes the new BH Ultralight one of the lightest production bikes on the market these days. But there are other updates besides its improved aerodynamics, too. For one, BH finally gives the Ultralight bigger tire clearance. Officially, its only 32mm, because of the number of ultrawide rims out there. But they say that most 35mm tires will fit, with their required 6mm clearance between the frame & fork at its closest point. Theyve also refined the bikes geometry around a steep 74 seat tube angle for more forward weight balance. And BH claim new super short 405mm chainstays for faster acceleration and a more direct responsive ride feel. Although their geometry tables still show the same 410mm stays of the previous generation.The result is a bike that moves beyond the traditional concept of a pure climbing machine to embrace a much more versatile approach. The new Ultralight retains weight figures that place it among the lightest road bikes in its category, but now combines this advantage with more efficient aerodynamics, greater integration and clearance for wider tyres. It is designed to accelerate quickly on climbs, but also to maintain high speeds, tackle technical descents and compete effectively on a wide variety of routes.Tech detailshi-mod Toray T1100G carbon monocoque frameAir Bow aerodynamic tapered steer, full carbon forkHollow Core Internal Molding (HCIM) for ECL Evo carbon layupclaimed tire clearance up to 35mm (guaranteed max 32c tire clearance on wide rims)fully integrated internal cable routing through the headsetelectronic shifting onlyproprietary D-shaped aero seatpost with hidden wedge-style clampintegrated Planck taillight magnetically attaches to the post (included on top models)new lightweight, 55mm deep BH Evo Stealth aero carbon wheels (included on top models)PressFit BB386 EVO bottom bracketflat mount disc brakeslightweight machined 12mm thru-axles with integrated hidden leversUDH rear, removable front derailleur braze-on mountUCI-approved frame5 frame sizes (XS-XL)2027 BH Ultralight Pricing, options & availabilityThe new Ultralight is available on five stock frame sizes (XS-XL), three standard frameset colors (marbled red, crystalline white & raw black carbon), and the BH Unique custom paint program.

At 7000, the Ultralight 7.0 upgrades to Ultegra Di2 and SC45 wheels. Then, at 7500, the Ultralight 8.0 adds a powermeter crankset to the Ultegra groupset, and includes the Planck taillight. Plus, the 8.0 adds BHs own new 1350g Evo Stealth 55mm deep, 23mm internal carbon wheels with aero-bladed carbon spokes and ceramic bearings.2027 BH Ultralight 9.0At the top-tier, the 8500 BH Ultralight 9.0 gets a Dura-Ace group, the BH Evo Stealth wheels, and the Planck taillight. Thats a 15% lower price than the same spec level four years ago, and now in a bike that claims a complete weight of just 6.7kg (size S, without pedals).2027 BH Ultralight 9.0The new bikes will be available in BH dealer bike shops starting in November, while custom-painted BH Unique bikes would start shipping at the end of January.BHbikes.com
