SRAM X01 BB30 Crankset

SRAM X01 BB30 Crankset

Anyone who's ever dealt with granny ring induced pedal feedback knows that front derailleurs are for the birds, as far as mountain biking is concerned. So if you're ready to ditch the front derailleur, and you're looking for the simplest, lightest setup, the SRAM X01 BB30 Crankset fits the bill. With an oversized BB30 spindle for maximum stiffness, and sleek yet durable carbon fiber arms, lightness and power transmission will be the least of your concerns. But perhaps the biggest breakthrough is the X SYNC chainring profile, which, when combined with SRAM's Type 2 clutch rear derailleur, makes a chain guide entirely unnecessary. Welcome to the future, we think you're going to like it. Borrowing heavily from its XX1 sibling, X01 is designed to works as a part of a system, with each piece designed for precision and seamless execution. Individually, these components represent a radical approach to building a more effective bicycle transmission. And taken by itself, the X01 Crankset sets itself apart with its sleek carbon fiber arms and revolutionary X SYNC single chainring. The carbon arms are mated to an aluminum spider for a lightweight single ring setup interface. The X SYNC chainring is designed for maximum chain retention, with each tooth CNC machined to support the inner and outer links. The machining process provides a variable thickness from tooth to tooth, so the chain and chainring lock together as you pedal. When taken in conjunction with the Type 2 roller clutch rear derailleur, chain retention is no longer an issue, which frees the drivetrain from the drag of chain guides. The new chainring's 94mm bolt circle diameter also sets it apart from others in the SRAM catalog. It provides a stiff interface that powerful riders will appreciate. Granted, as compared to XX1, the larger bolt circle diameter means that the X01 Crankset forgoes the option of a 28 tooth chainring, but that should only be a factor for those whose rides regularly include long, steep,...
