Hollow-forged from 6061-T6 aluminum, both crank arms are hollow so they are super stiff, yet lightweight. The crank arms spin on a beefy 30mm spindle permanently fitted into the drive-side arm.  These cranks offer direct-mount sprocket compatibility for additional weight savings, or run them with the included 104 BCD spider adapter.\u003c\/p\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eCNC machined 6061-T6 aluminum crank arms are lightweight, strong, and stiff\u003c\/li\u003e\n\u003cli\u003eDesigned and optimized for chainrings and spiders with SRAM's 3-Bolt mount style\u003c\/li\u003e\n\u003cli\u003eIncludes 4-bolt, 104 BCD spider\/adapter (Not compatible with CK-1 crank spider\/adapter)\u003c\/li\u003e\n\u003cli\u003e30mm spindle provides increased stiffness and efficient power transfer\u003c\/li\u003e\n\u003cli\u003ePedal washers included and required\u003c\/li\u003e\n\u003cli\u003eBottom bracket sold separately\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Promax","offers":[{"title":"170","offer_id":46704475242744,"sku":"CK21-030HF170-BK","price":299.99,"currency_code":"USD","in_stock":false},{"title":"172.5","offer_id":46704475275512,"sku":"CK21-030HF172-BK","price":299.99,"currency_code":"USD","in_stock":true},{"title":"175","offer_id":46704475308280,"sku":"CK21-030HF175-BK","price":299.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0357\/3930\/4074\/files\/CK0497_de171a15-3d3d-49be-87c8-22ef9bdfcd3f.jpg?v=1755501688","url":"https:\/\/shopbikesupply.com\/products\/hf-3-crankset","provider":"Sierra Bicycle Supply","version":"1.0","type":"link"}
