The stiff and ultra-lightweight road bike. It's not just about the weight but what you do with it, too.

Designed as the evolution of the award winning DIABLO, the BURAsl was performance engineered to achieve the highest stiffness to weight ratio, ensuring the most efficient and direct power transfer.

A number of changes were made to the BURAsl to further decrease the frame weight. The carbon lay-up was reengineered to utilize longer strips of carbon pre-preg instead of shorter pieces, minimizing the number of overlapping layers.

BURAsl's front triangle is made from NEILPRYDE C6.9 unidirectional carbon fiber and incorporates our proprietary Exoskeleton technology. External carbon fiber ribs integrated in the key joints of the monocoque front triangle ensure the BURAsl frame responds immediately each time you step on the power.

The rear triangle incorporates our One-piece Stays, a unique design for the chain stay and carbon fiber dropout, together with ultra-thin seat stays. This combination enables the ride to be tuned for the perfect balance between power transfer and compliance.

Carbon fiber front and rear drop outs, a Press Fit 30 bottom bracket and carbon headset cups further reduce the frame weight without sacrificing durability or performance.

That is it: bare minimum weight and maximum performance. The only thing we piled on was the unflinching NEILPRYDE attitude, which weighs nothing.

"The Bura SL has the potential to be the lightest bike in the bunch but the down tube’s girth and thick chainstays cloak this fact... giving you a stealthy edge!"

High stiffness to weight ratio

BURAsl's front triangle is made from NEILPRYDE C6.9 uni-directional carbon fiber, the highest modulus suitable for bikes, which results in a 710g frame weight.

  • One-piece Stays

    Deep section chainstay combined with our Onepiece Stays construction result in decreased weight, increased stiffness in the rear triangle and improved power transfer

  • PU Molding

    A high-tolerance control of wall thickness in bottom bracket and head tube is possible through use of PU mandrel and internal layer of 3k carbon fiber

Exoskeleton technology

First developed for the DIABLO, external carbon fiber ribs are integrated into the head tube and seat tube joints increasing lateral stiffness and torsional rigidity of the monocoque front triangle.

Offset seat tube for increased bottom bracket stiffness.

Ultra-thin vibration dampening seat stays for tuned compliance.

Square section toptube for torsional rigidity.

Mechanical (external cable routing) or Shimano Di2 (internal cable routing) ready 1-1/8 upper and 1-1/4 lower headset bearings.

Press Fit 30 bottom bracket.

Carbon fiber headset cups.

NEILPRYDE 27.2mm seat post for increased compliance.

Carbon fiber front and rear dropouts
