The 24mm HollowTech II spindle requires a compatible Shimano external bearing bottom bracket (sold separately in most cases). Not compatible with square taper, ISIS, or other bottom bracket standards. The crankset is designed for single-chainring setups—riders wanting multiple chainrings should consider other options. Ideal for downhill mountain biking, freeride, and gravity-oriented disciplines where crankset strength and stiffness are critical for handling repeated impacts, hard landings, and high-torque pedaling situations. The 36T chainring suits gravity riding where climbing efficiency is less important than descending control and having appropriate gear ratios for technical terrain. Choose crank length based on rider height and preference: 165mm for shorter riders or those prioritizing ground clearance, 170mm for average heights, 175mm for taller riders or those wanting increased leverage.\u003c\/p\u003e \u003cdiv\u003e\u003cp.\u003e\u003ci\u003e\u003cu\u003e\u003cfont size=\"2\"\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/p.\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e**Due to unique nature of this item, ALL sales of this product are FINAL.

You must purchase a compatible square spindle bottom bracket separately—ensure the spindle length matches your frame's chainline requirements (typically 113mm-122mm for BMX). The 110mm BCD fits most BMX sprockets with 5-bolt patterns; verify your sprocket's BCD before installation. Suitable for riders building or upgrading bikes with square taper systems, common on mid-level BMX racing and freestyle setups. Forged aluminum construction makes these appropriate for riders who need durability beyond entry-level cast cranks but don't require the weight savings or stiffness of chromoly three-piece systems.
