They are crafted from CNC machined 7075 aluminum and feature an anodized finish for exceptional durability. Ovality has been optimized for each chainring size, ranging from 10.2-14.4%, with timing of 110.5-116.3° after TDC (top dead center). - Oval shape reduces stress on knees, helps to keep your legs fresh, and does not feel any different while riding - The unique, patent-pending narrow-wide tooth profile keeps the chain in place - Teeth have been 3D-machined for ultimate mud shedding and quieter operation - Provides excellent weight-to-strength ratio - 6mm offset for standard 49mm chainline

BSA is equivalent to English threading. English threading on MTBs mean a 73mm-wide, 34mm-inside-diameter shell with reverse threading on the drive side. It's the most common threaded standard employed today. This kit works with 24mm diameter cranks, such as Shimano, FSA, Rotor, and others. Choose between two bearing types for the cups. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag. For MTBs, English threading, thanks to history, is pretty much the one threaded standard. It works great. 24mm spindles easily fit through the shell, allow for large bearings to be employed in the outside cups. What's more, they rarely creak and seal up well. Lots of things slow bikes down; bearings shouldn't be among them. CeramicSpeed Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That's in the range of a 75% drag reduction compared to standard bottom brackets. The bearings last at least 3x longer than other bearings. Coated bearings have even less drag. These bearings come packed with LongLife Grease, best for muddy conditions. For less drag when riding in cleaner environs, you can coat the bearings with either All Round Grease or lowest drag TT and Track Grease, which is designed for clean conditions. In The Box - 2 threaded cups with bearings - 2 dust covers with built-in spacers - Spacer tube - 10ml syringe of LongLife grease - Sticker sheet
