Madera is a new component company run by Profile in the USA. These cranks are the same great quality as we have come to expect from Profile but are made slightly cheaper for those of us on a budget, basically a few minor aesthetic manufacturing processes are left out on these like stamping logos etc. RHD/LHD compatible in 175mm only. ###section### Product Specs Crank Type: 3pc Spindle Diameter: 19mm Includes BB: No Weight: 807g / 28.5oz ###shogun-image-section###
