The Speedco M2 Alloy BMX Race Frame-Matte Black/Yellow line of alloy frames is aesthetically designed to replicate Speedco’s Flagship model, the Velox Carbon. The custom 7005 series alloy tubeset on the M2 frames are heat treated and double-butted for weight reduction and increased strength. The down-tube on the M2 line is oversized and tapered slightly throughout the sizes to enhance response and ensure that riders of all sizes benefit from the maximum rigidity for their body weight. The chain-stay width follows suit as these bikes were built to sprint, and peak performance out of the gate and corners under high power output is top priority in the M2. Lastly, an integrated chain tensioner system is seamless throughout the 16 sizes in the M2 line and will keep the rear wheel locked in under the highest wattage output you can only dream of. Do you have what it takes to put the most responsive alloy bike you’ve ever ridden through it’s proper paces?

YOUTH FEATURES (MINI- EXPERT 24″)

• Euro BB: The bottom bracket on our youth frames is a euro threaded 68mm shell which works efficiently with all crank systems whether pinch-bolt or square-taper.
• 10mm drop-out: a 10mm drop-out with an included outside adapter to integrate with the frames chain-tensioner works efficiently while avoiding direct axle to tensioner contact.
• Integrated 1-1/8″ head-tube: The head-tube on our youth line is a standard integrated system which allows for easy headset drop-in install, and accommodates both 1 & 1-1/8 steerer tubes with ease.

PRO FEATURES (PRO AND LARGER)

• BB86: There are 3 popular bottom bracket standards for BMX euro, BB30, and BB86. A euro is a threaded BB, the shell is 68mm wide and it uses 24mm (92mm total) of outboard bearings and a 24mm crank spindle. A BB30 is similar, 68mm shell but promotes a larger crank spindle (30mm) therefore a larger spindle to flex the same narrow bottom bracket junction. The M2 Alloy uses a BB86 which is a 86mm BB shell and press-fit bearings that equal 4mm added to the 86mm shell (92mm total) while using a 24mm spindle. The advantage to our BB is the wider down-tube and chain-stay described above. Rigidity is key for first straight pull and accelerating out of turns, while a flimsy frame will just get you cut off out of the gate.
• 10/15mm dropout: The dropout on the M2 Alloy is all about efficiency. With an integrated chain tensioner through the front of the dropout, the need to over-tighten your wheel has been eliminated. Each dropout uses two flex-free 4mm adapters to insure your wheel isnt gonna move regardless of how many horses youre putting down first pedal.
• Tapered head tube: The standard for high-end race frames is a tapered head tube. A tapered head tube uses a 1-1/8 top bearing and a 1.5 bottom bearing and allows us to use a fork both lighter and stronger than ever before.
• Tubeset: The M2 features a fully double-butted 7005-aluminum tube set. The massive down-tube tapers 52mm to 72mm top to bottom, which eliminates flex and allows your power to be efficiently converted to speed as you accelerate from the gate, and corners.
