Profile's Race Cranks with no bosses. At this point, pretty much only compatible with the Tree sprocket (but SOON Profile!), but people have asked for these, so here they are.
There's a reason that Profile Racing's BMX Race Crankset has been manufactured for longer than most parts companies have been around. Made in the USA from 4130 Crome Moly, our crankarms are the standard by which all other cranks are measured, and have been for years. Our 48 spline 4140 Steel Bottom Bracket Spindle revolutionized BMX when it was introduced, instantly rendering obsolete inferior square-tapered BB's. Added to all that is our Limited Lifetime Warranty on the arms and the spindle against bending and breaking to original purchasers.
Includes arms, spindle, bolts, and installation tool.
