Our award winning ENG Threaded bottom bracket is designed for use with a BSA/Euro/English threaded frame. It comes in 8 different colors and can support 24mm cranks such as Shimano and FSA. It can be used with 22/24mm SRAM GXP/Truvativ cranks with the addition of our adapter kit (select SRAM crank above). There are 3 different bearing choices to best meet your needs: Standard Bearings: Use for road bikes in dry/no salt environments. Full Stainless Steel Bearings: Use for extreme distance riding (>200miles/week), BMX, MTN, and other varying conditions. Full Stainless Steel Bearings with CX Seals: The CX seal is for riding conditions where water, dust, and debris can get into the bearing and degrade it prematurely. Use for MTN, BMX, Cycle Cross, or other wet and dirty conditions. NOTE: This is not for timed road biking as the extra seal slightly increases wattage. NOTE: For 22/24mm SRAM/Truvativ cranks you will need to select the SRAM option on the crank menu. NOTE: For BMX cranks that use a 19mm spindle, road cranks with a 19mm spindle, and the FSA omega you will need our 19mm bushing kit which is sold separately. Recommended Tools: Park Tool BBT-9, Park Tool Anti-Seize Compound
