Serious cyclists, listen up! This GXP hollow integrated crankset is a game-changer for your road bike or folding bike setup. Available in three lengths - 165mm, 170mm, or 175mm - so you can pick what feels right for your riding style. Made from premium 7075 alloy aluminum that's crazy lightweight (just 467g to 490g depending on size) but still tough as nails. The hollow design cuts weight without sacrificing strength, and the GXP direct mount system locks everything in place securely - no worrying about things coming loose mid-ride. Includes a bottom bracket that fits 68mm to 73mm shells with threaded type BC1.37 × 24T, working with most bikes out there. The 109mm shaft length and 24mm outer diameter provide smooth, reliable power transfer from your legs to the road. Perfect for upgrading your current setup or building that dream bike from scratch. Whether you're climbing hills, sprinting flats, or just cruising around town, this crankset delivers the performance you want without breaking the bank. Comes with everything you need: bottom bracket, left and right crank arms, and all necessary screws. Just pick your size and get ready to feel the difference on your next ride!
