SpeedCo M2 Alloy BMX Race Frame-Black/Gray/Olive

The Speedco M2 Alloy BMX Race Frame-Black/Gray/Olive is loaded with hi-tech design and construction elements to deliver max performance at high speeds. Built from heat-treated and double butted 7005 aluminum alloy, the M2 is designed after the popular Velox Carbon models, with added strength and reduced weight. Featuring an oversized down-tube that tapers a bit throughout the size range, the M2 series gives riders of all weights the perfect frame stiffness they need to achieve peak race performance. The wider down-tube and chainstay mean the BB86 delivers efficient power whether out of the gate, in the straights or hugging the corners. The dropouts on the M2 use two flex-free adapters to keep your wheel secure and you won't need to over-tighten the wheel thanks to the integrated chain tensioner. Smooth and efficient power delivery at a budget-friendly price.

FEATURES

• 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 isn’t gonna move regardless of how many horses you’re 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.
