Product Description
Perfection would almost intimate a stasis. Whatever is truly perfect would have to be the last form of an evolutionary process. We know that this is just not possible with the current pace of technological advancements. However, at the moment there are a number of bicycles that must surely be nearing the top of the pinnacle. The BH Ultralight is one of those that deserve the distinction. Its performance is only overshadowed by its contempt for the traditions of the scale. As the name would imply, the Ultralight is just that. In a painted 54cm version, the frame weighs a mere 747 grams.Of course, light weight is nothing without performance. And who hasn't witnessed the laughable show bikes that simply aren't rideable as a normal road bike. Chris Cocalis of BH USA made the goals for the Ultralight very clear - make it the stiffest and lightest road racing frameset on the market. With a defined concept, BH was able to make the Ultralight just that by utilizing a number of key elements. These are the BB386 bottom bracket, their Formula 1 spec high modulus carbon fiber blend, and proprietary molding techniques. You might be wondering how the bottom bracket could relate to the performance of the bike. At 86mm in width, it shares that same dimension with a standard pressfit (BB86) bottom bracket. The benefit with either is that the shell has the real estate to accommodate larger diameter down and seat tubes. As the cross-section of a tube increases, so does the torsional stiffness for any given wall thickness. The difference between the two standards has to do with the inside diameter. Where a BB86 has a 37mm ID, the BB386 has a 46mm ID. And the reason that BB386 is superior to BB86 is that it allows the use of the newer cranksets with 30mm alloy spindles. They are roughly 40-50 grams lighter than their steel spindled 24mm counterparts in addition to offering greater torsional stiffness.The BH Ultralight is molded as a monocoque including ultra-high modulus carbon fibers.
