OVERVIEW and REVIEWS

The SuperB 275 titanium mountain bike frame is not just an XC on smaller wheels.  The complete design is aimed at smaller and lighter riders, or simply someone who wants to utilize the smaller 27.5″ wheel size.  Plainly, it’s the purest racer in our SuperB series lineup.  The rear triangle accommodates the narrower cross-country tire width (up to 2.4) rather than plus-size tires.  In addition, the SuperB 275 optimizes short 100mm travel suspension forks.  It’s also fun on a rigid fork with an approximate 490mm axle to crown.

The SuperB 275 is a compact and minimalist design built with material weight in mind.  It’s fabricated with smaller frame tube sizes, and as a result, it’s the lightest of the SuperB group!  Therefore, we recommend the X-Small through Medium frame sizes have a rider weight limit of 175 pounds.  However, there is no limit on the Large and X-Large frames.

Not only is pedaling efficiency maximized through the geometry and shorter fork travel, but also, the 27.5″ wheel size optimizes acceleration without sacrificing rolling speed.  And, as a result, the lightweight SuperB 275 has proven itself to be a podium machine!  Multiple highly competitive athletes have race wins and Top 5 season finishes on it.  If you want the lightest and quickest bike for XC racing, or just plain fun, this is it!

    Binary Bicycles provides the absolute best customer service I’ve ever experienced. George answered all my questions and built the most amazing bike I’ve ever ridden. And having ridden for almost 40 years, I’ve ridden a lot of bikes! His geometry and bike design, attention to detail, and quick email responses from George and Jalene are unsurpassed. I can’t wait to order my next custom frame! Thank you again for such a wonderfully designed bike.

DEBUGGING the FAQs

  • 12mm thru axle
  • conventional sliding dropout inserts and titanium insert hardware
  • 35mm seat post clamp

Yes! While conventional sliding dropout inserts are traditionally provided with your frame, you can easily upgrade to SRAM UDH compatible inserts and axle. Just check the appropriate upgrade option while adding your frame to the cart and we'll set you up accordingly. (Note: if you upgrade to the UDH inserts and axles, you will not receive the conventional inserts.)

The SuperB 275 is designed to use a threaded 73mm BSA bottom bracket.

Any headset with a zero stack 44mm internal upper cup and a zero stack 56mm lower cup should work just fine.

  • Lower: ZS56
  • Upper: ZS44
  • Stem Clamp Diameter: 28.6 Threadless
  • Crown Race: 40

We recommend running a 27.5" 100mm travel suspension fork or a rigid fork with the axle-to-crown length as close to 485mm as possible.
