M2 Pro Frame Features Cruiser Pro 21/Pro XL 21.75
BB86 – press-fit BB86 is our bottom bracket of choice throughout our entire pro line of frames, both for the Velox & M2. The cups efficiently press directly into the shell with ease, but the benefit of this system is the oversized shell width. The 86mm shell accommodates a super wide chain-stay and a massive down-tube junction. These components maximize rigidity and responsiveness needed in our pro models.
Tapered head-tube - The standard for pro sized 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.
10/15mm drop-out - 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.
