Hey cyclists! This GXP crankset is a solid upgrade for your road bike. You're getting a complete setup with left and right cranks, your choice of chainring size (from 40T to 50T), and a bottom bracket that fits BB68-73mm frames. The crank arms come in 165mm, 170mm, or 175mm lengths - perfect for getting that perfect fit. It's all made from 7005 high-strength aluminum alloy with a full CNC process, so it's lightweight but seriously durable. The hollow integrated design shaves off weight without sacrificing strength. The narrow-wide tooth profile on the chainring is awesome for preventing chain drops, and it works with 8-12 speed systems. The bottom bracket has a 24mm shaft diameter and uses GXP direct mounting - super straightforward installation. Total weight is around 467g for the 165mm version plus 95g for the BB. Just make sure to double-check your frame compatibility and preferred chainring size before ordering. Seriously, if you're building up a new bike or upgrading your current setup, this crankset gives you pro-level performance without the crazy price tag. The black anodized finish looks slick too!
